Problems solved by technology

The chemical diagnosis method is to use chemical analysis to measure the content of nutrient elements in soil and plants, and judge the nutritional status of plants based on this method. It has the characteristics of accuracy and rapidity. Diagnose plants during growth and find out the situation for topdressing, but the existing nutritional diagnostic standards are not perfect, and a lot of systematic research work is needed

Embodiment Construction

[0025] Through the specific examples given below, the present invention can be further understood, but they are not limitations of the present invention.

[0026] Special fertilizer formula for tea tree

[0027]

[0028]

[0029] Fertilization should be relatively concentrated, whether it is basal fertilizer or top dressing, the tea gardens planted in strips should be applied in strips, the tea gardens in clusters should be applied in clusters, and young tea gardens should be applied in seedling holes. The position of fertilization is generally based on the principle of vertically lowering the crown of the tea tree. For young tea trees that have not formed a shaggy face, the distance from the fertilization point to the root neck: 5-10 cm for one-year-old and two-year-old tea trees, and 10-15 cm for three-year-old and four-year-old tea trees. Fertilize on one side or both sides of the flat tea garden, and fertilize on the top side of the tea row in the slope tea garden or...

Abstract

The invention relates to a special fertilizer for tea trees of northern tea gardens and applying technology. Compared with only applying urea and only applying a controlled release fertilizer, applying the special fertilizer can increase the quantity of root microbes, enrich microbial populations, improve root environments of the tea trees, decrease accumulation of polyphenol substances in tea leaves, increase the total amino acid and water extract content of the tea leaves and remarkably improve the quality of the tea leaves. Besides, nutrients released by the special fertilizer exactly meet the requirement of the tea trees on nutrients, the use ratio of the special fertilizer is increased, and cost is saved.

Description

technical field [0001] The invention belongs to the field of chemical compound fertilizer technology and special crop cultivation technology, and in particular relates to a special fertilizer for tea trees and corresponding matching fertilization technology. Background technique [0002] In tea garden management, fertilization is a key control point to improve tea yield and tea quality. [0003] The current methods to guide the fertilization of tea gardens mainly include: the empirical method based on the experience of the masses; the effect function method of "fixing fertilizer after delivery" based on field experiments and biostatistical principles; The nutritional diagnosis method of "fertilization"; the formula fertilization method of "prenatal fertilizer" under the target benefit, etc. The empirical method depends entirely on the personal experience of the tea grower. The actual operation is simple and can be completed without complicated procedures. However, it lacks ...
