Fertilization Methods and Principles of Bonsai

There are mainly two kinds of fertilizer for bonsai plants: organic fertilizer and inorganic fertilizer. Organic fertilizer mainly includes: human feces and urine, stable manure, poultry manure, green manure, bone meal, plant ash, bean cake, sesame sauce residue and so on, as well as waste organic matter in daily life, such as fishy water, rice washing water and so on. Inorganic fertilizer mainly refers to all kinds of synthetic chemical fertilizers. Commonly used are urea, ammonium sulfate, potassium dihydrogen phosphate, calcium superphosphate, ferrous sulfate and so on.

The application of chemical fertilizer is more clean and hygienic, and the bonsai placed indoors should mainly be topdressing chemical fertilizer. The nutrient elements contained in chemical fertilizer are more specific. When plants are in urgent need of certain nutrient elements or show element deficiency, the effect of corresponding chemical fertilizer is better than that of organic fertilizer.

The main results are as follows: 1. Siduo "thin and thin, apply more before germination, apply more during bud pregnancy, and apply more after flowering."

2. "Si Shao" fat and strong less application, sprouting less application, flowering less application, rainy season less application.

3. "the four nots" do not apply, do not apply new plants, do not apply in the heat of summer, and do not apply dormancy.

Different stages of plant growth and development have different requirements for nutrients. In general, in late spring and summer, plants enter a period of vigorous growth, it is appropriate to apply more fertilizer, the growth rate slows down after autumn, less fertilizer should be applied to avoid overgrowth, and most plants enter the dormant period in winter. Fertilizer should be stopped. The bonsai of flowers and fruits should be applied with phosphate fertilizer during the period of flower bud differentiation and before and after flowering.

1. Base fertilizer

Base fertilizer is the fertilizer that is supposed to be applied to the soil. Base fertilizer is used in the pot or when mixing mud in winter, mainly cake fertilizer, hair, poultry feet and so on.

2. Topdressing

Topdressing is the fertilizer applied in the flower growing season. Topdressing is applied during the growth period of flowers and trees, usually once every half a month or so, not too much. The topdressing of potted flowers is mainly irrigated with dilute liquid fertilizer. Rarefied liquid fertilizer should be made in spring in advance and can only be applied after it is fully ripened at high temperature in summer. There are two kinds of rarefied liquid fertilizer:

1. Fat water: put the broken bone pieces, bean powder, rice washing water, sesame sauce dregs, etc., into the vat, add the water cover, place it in the sun and mature at high temperature. Diluted with water when applied, it is suitable for all potted flowers.

2, alum fertilizer water: in the bubble fertilizer water, add 500 grams of ferrous sulfate (black alum) every 50 kilograms of water, and then dilute it with water. it is suitable for flowers that like acid soil, and alum fertilizer water also plays a role in promoting the luster of leaves.

Principles of fertilization:

1. Fertilization must be timely.

Timely fertilization is to fertilize flowers when they need fertilizer, and it is most appropriate to apply fertilizer when it is found that the leaves of the plants become lighter and the growth is weak.

2. Fertilization must be appropriate.

Fertilization must be applied differently according to the different growth stages of flowers. For example, at the seedling stage, there should be more nitrogen fertilizer, fertilizer and water, and more times, so as to promote the rapid and robust growth of seedlings, more phosphorus and potassium fertilizer, more nitrogen fertilizer to make the leaves green, and more phosphorus and potassium fertilizer to flowers and fruits, so as to make the plants blossom and bear fruit early, and make the flowers and fruits brightly colored.

3. Fertilizing must master the season.

Flowers grow rapidly and vigorously in spring and summer, and can be fertilized more. Flowers grow slowly after autumn, and should be fertilized less. They should be dormant in winter and should stop fertilizing.

4. Time must be mastered in fertilizing.

Fertilization of potted flowers should adopt the principle of "eat less and eat more" (that is, "thin fertilizer is applied frequently"). Generally, thin fertilizer and water can be applied every 7-10 days from the beginning of spring to the Beginning of Autumn, and 15-20 days after the beginning of autumn.

5. Temperature must be mastered in fertilization.

Fertilization should be carried out on a sunny day. Potted flowers should not be fertilized around noon when the summer temperature is high, because the pot soil temperature is high, topdressing is easy to hurt roots, and the effect of application in the evening is the best.

6. The soil must be loosened when applying fertilizer

Before applying thin liquid fertilizer to potted flowers, the surface of potted soil should be raked loose, and then fertilized until the potted soil is slightly dry. After fertilization, the leaves should be sprayed with water immediately so as not to pollute the leaves with residual liquid. Water must be watered the next day of fertilization.
