How to fertilize plants in winter

Jiulixiang likes fertile soil containing humus. If the soil is lack of nutrients, the growth of jiulixiang will be affected.

Jiulixiang likes fertile soil containing humus. If the soil is lack of nutrients, the growth of jiulixiang will be affected. Especially at the flowering stage, jiulixiang needs more nutrients. Therefore, it is necessary to maintain sufficient nutrients in the soil so that jiulixiang can bloom. It is best to move the plant to a ventilated and sunny place outdoors, and the illumination time given every day shall not be less than 5 hours, so as to promote the growth and development of the plant.

Too much watering also has a low demand for water. It can store a certain amount of water charge in its body, so it is very drought resistant. Therefore, when watering, you must pay attention not to water too much to avoid ponding(5 gallon plant pot). Moreover, sufficient water will accelerate the growth rate of Rosa roxburghii, resulting in nutrients being absorbed by branches and not flowering. The normal watering method should be watering after the soil is completely dry, rather than being too wet.

At the initial stage of planting, apply less fertilizer until the flower stems are about to be pulled out or before flowering. Generally, it is applied once after one month of planting, once before flowering, and once every one and a half months or two months thereafter. Insufficient light tuberose is a photophile plant. Before flowering, ensure that there is sufficient sunlight every day, which can promote the flowering of the plant. Otherwise, due to insufficient light, it will affect the differentiation of flower buds, resulting in the non flowering of the plant.

Lack of light, thyme likes soft sunlight and is afraid of strong direct sunlight, so it is best to put thyme in an environment with scattered sunlight during normal maintenance. If there is no light for a long time, the growth of thyme will slow down and is not conducive to the differentiation of flower buds. Generally, apply decomposed liquid fertilizer every half a month or so during the growth period of gardenia, and the concentration of fertilizer should be lower.

In winter, you should also learn to control water. Water once a week, a small amount of water, but also ensure that the soil is slightly wet. In this way, the probability of falling leaves will not be great, which will make Jasmine ensure that its branches and leaves are green and ornamental. If you water too much, there will be accumulated water, leading to the root rot of the plant(15 gallon pot). Some Chimonanthus chinensis are out of control due to water and fertilizer, especially the excessive amount of nitrogen fertilizer, resulting in the crazy growth of branches and leaves, affecting the differentiation of flower buds, resulting in non flowering.

Therefore, wintersweet should be applied with nitrogen fertilizer in spring, phosphorus and potassium fertilizer should be increased in summer and autumn, and less or no nitrogen fertilizer should be applied to promote flower bud differentiation as soon as possible. 3. Excessive dampness: wintersweet likes light, and insufficient light will affect flower bud differentiation; The pot soil is too wet or the place is too wet, which is not conducive to flower bud differentiation. For this reason, water should be "drained" in late summer and early autumn, and it should always be placed in a sunny place, which is greatly conducive to the formation and expansion of flower buds.

The temperature is too low, and the longevity flower likes a warm growth environment. Generally, the temperature suitable for its growth is between 15 degrees and 25 degrees. If the temperature is lower than 10 degrees, it will cause the longevity flower to grow slowly, and the flowering period will be delayed, or even not bloom. If it is lower than 0 degrees, it will be frozen to death. Therefore, when we maintain the longevity flower, we should take warm measures, especially the flower friends in the north, to let the longevity flower bloom, it is best to keep the temperature above 15 degrees.

Improper illumination Osmanthus fragrans especially like sunlight and can accept direct sunlight. Sufficient sunlight can make Osmanthus fragrans bloom more(10 gallon nursery pots). If Osmanthus fragrans grow in a dark environment for a long time, it will cause Osmanthus fragrans not to bloom, and in serious cases, it will lead to yellowing and drying of branches and leaves, and even death. Therefore, we must ensure that Baocheng Osmanthus fragrans can get sufficient light, especially in indoor maintenance, and we should ensure the light of Osmanthus fragrans.

Improper fertilization is very important if you want osmanthus flowers to bloom. You can use more nitrogen fertilizer during the growth period to make the branches and leaves more luxuriant. You can use more phosphorus and potassium fertilizer during the flowering period, so as to ensure that there are enough nutrients during flowering. The concentration of fertilizer should not be too high to avoid burning the roots of osmanthus flowers, but you must pay attention not to use manure for osmanthus flowers.

The branches and leaves of Catharanthus roseus are luxuriant, and the demand for nutrients is also relatively large. Therefore, if we want Catharanthus roseus to bloom, we need to ensure adequate nutrient supply, which requires us to apply fertilizer regularly. Generally, we mainly apply fertilizer containing phosphorus and potassium before the flowering period, and some potassium dihydrogen phosphate can be used during the flowering period, which is conducive to extending the flowering period. The time of fertilization is about every ten days, and the concentration of fertilizer should be lighter.

In winter, we need to stop fertilizing jasmine, especially the jasmine maintained in the north, which is in a dormant state and will not grow. If fertilizing, the plant roots cannot be absorbed, it will burn the plant roots and make it unable to grow normally. In serious cases, it may also cause the death of jasmine flowers(4 gallon pot). In this way, after a period of time, it absorbs enough sunlight and will recover and begin to bloom.

Insufficient fertilization means insufficient nutrient supply. The temperature is too low, so it is suitable to grow in a relatively warm environment. If it is kept in a place with low temperature, it will grow poorly and cannot bloom. At this time, we need to find ways to increase the temperature around the plant and control it above 15 ℃, preferably above 25 ℃. The simpler way is to move it to a warmer place.

If you don't get enough nutrients, the plants will lack nutrients and it will become difficult to blossom. Saffron should not grow in clayey soil or alkaline soil. When cultivating saffron, it is necessary to provide it with humus loam rich in organic matter, which can be mixed with sapropel, perlite and vegetable garden soil, and the pot soil should be replaced every 1-2 years to maintain the normal growth of saffron.

Put it under the stove and bake it(20 gallon nursery pots). After baking, the tubers can be relatively dry, which forces the tubers of evening jasmine to enter the dormancy period, which is conducive to the growth and flower bud differentiation after planting in the next spring. Excessive fertilization and excessive nitrogen fertilizer after planting will lead to the stem and leaves of Tuberose growing in vain. This situation will cause Tuberose to bloom less, and even not bloom in serious cases.

The flowering period of Osmanthus fragrans is generally from September to October every year, and the specific flowering time of the plant will be affected by the variety, climate and other factors. Therefore, if Osmanthus fragrans does not bloom, it is very likely that it is not in the flowering period. In this case, we just need to wait patiently. Generally, leaves will begin to fall in November, and winter will enter the dormancy period. If it is inconvenient to move, you can also keep warm by bagging.

Carnations like a cool growth environment. The temperature suitable for the growth of carnations is between 14 ° C and 21 ° C. carnations are very afraid of heat. When the temperature exceeds 35 ° C, the growth of carnations will stop. At this time, carnations will not bloom naturally. Therefore, when the temperature is too high in summer, we should spray water to cool carnations. If the temperature is lower than 9 ° C in winter, carnations will enter dormancy and will not bloom at this time.

In terms of isolation, artificial evolution can go beyond the isolation conditions formed by spatial distance and mountains, oceans, lakes and deserts, and create various artificial isolation environments to promote the formation of new types(25 gallon pot). The actual situation is that natural evolution has no purpose and plan to follow in terms of the purpose and planning of selection, while artificial evolution has developed from the initial aimless and unplanned unconscious selection to purposeful and planned selection.

This is a comprehensive and philosophical generalization. These variations that occur under artificial selection are often detrimental to the organism itself in the wild. It should also be noted that there is consistency between natural selection and artificial selection for some traits. For example, the adaptability to various environmental stresses and the improvement of the reproductive ability of plants with seeds and fruits are not only the direction of natural selection, but also the basic requirements of artificial selection.

Wild cabbage has developed apical buds and lateral buds, which can produce lush leaf clusters without forming special storage organs. Although there are great differences in morphology and structure among the varieties, they still retain many common characteristics of their ancestors' primitive wild species. For example, all varieties have racemes with yellow flowers of different depths; Insect pollination habits; Self incompatibility in natural state; The varieties can cross with each other.

Humans began to cultivate cabbage more than 4000 years ago and introduced it to all parts of the world. Under the cultivation and selection of different environmental conditions, many cultivated varieties have been formed. For example, in the vegetative growth period, the lateral buds are in a state of inhibition, while the terminal buds are developed, first growing into leaf clusters, and then forming leaf bulbs(1 gallon nursery pots wholesale). The terminal buds are suppressed and the lateral buds are developed, forming many lobular bulbs of Brussels sprouts, and the stems are shortened and expanded to form bulbous succulent stems.

Cauliflower with hypertrophy of flower buds at the top to form fat and tender flower balls, with developed flower branches, forming many fat and tender flower branches; And kale with yellow, red, purple and other bright colors, which are mostly wrinkled and of high ornamental value. There are also other varieties with different characteristics not mentioned above, such as wrinkled cabbage, purple cabbage, etc. The difference between natural evolution and artificial evolution lies first in the subject of selection and the direction of evolution.

The concept of variety has been discussed and described in various books and periodicals at home and abroad. The commonness is to confirm that varieties are domesticated animal and plant groups with certain attributes. Stability refers to maintaining the genetic stability of the previous and subsequent generations under the condition of adopting the breeding method suitable for this kind of variety. For example, although the vegetative line variety is genetically heterozygous, it can maintain the stability and continuity of the previous and subsequent generations during asexual reproduction by means of bracket, layering, grafting, etc.

But there are some differences in which attributes. For example, the concept of variety in the crop volume of China Agricultural encyclopedia is "a crop type that is relatively homozygous and stable in genetics, relatively consistent in morphological characteristics and biological characteristics, and used as a means of production in agricultural production(black nursery pots). Based on this, the concept of variety is formulated that its main economic characteristics meet the needs of production and consumption markets in a certain period of time.

Jing Shixi summarized relevant discussions and proposed that the necessary and sufficient attributes of varieties should include five aspects: elite, adaptability, uniformity, stability and specificity, which are abbreviated as excellent, suitable, homogeneous, stable and special (in English, it is simply written as eausd). Varieties generally have high economic value, meet human needs, and can adapt to natural conditions and cultivation conditions in certain areas.

The guide to seed law (1969) issued by the food and Agriculture Organization of the United Nations and the International Association for seed inspection defines a variety as "a cultivated plant group that can be distinguished from other plants according to its specificity (morphology, cytology, chemistry, etc.), and will not lose its important characteristics due to reproduction (sexual or asexual).". Some international books and periodicals have made some other imprecise statements about the attributes of varieties, such as "after long-term cultivation and domestication".

Taking the evolution of cabbage as an example, wild cabbage is a kind of herb originated from the Mediterranean coast. In addition, there are many fan-shaped chimera varieties in ornamental plants, such as corundum, Cinnamomum, dragon head bamboo, etc. there are so-called somatic mutation types for ornamental purposes, such as golden Jasper, Jasper gold, etc(1.5 gallon nursery pots). Hybrid varieties are used in the production of some vegetables and flowers, and the stability and continuity between generations are limited to the repeated production of hybrid seeds every year.

Biological characteristics adapt to the requirements of ecological environment and agricultural technology in a certain region; Appropriate breeding methods can be used to maintain the uniformity of utilization and the genetic stability of previous and subsequent generations in the population, as well as the domestic animal and plant population with some marker traits that can be distinguished from other varieties. The combination of computer and other technologies can automatically analyze and process a large amount of data, which greatly improves the efficiency and accuracy of breeding.

The latter concept does not express that as a means of agricultural production, it should have the attributes of excellence and adaptability. Or simply expressed as a group of domesticated animals and plants with excellent, adaptive, neat, stable and specific performance that does not hinder utilization under specific conditions. These five aspects are also the main contents of new variety approval. Excellent refers to that when the population is used as a variety, its traits or comprehensive economic traits meet the market requirements and have higher economic benefits.
