Zinc-rich fruit tree ground nutrient and applying method thereof

Abstract

The invention relates to the field of microelement fertilizer research, in particular to a zinc-rich fruit tree ground nutrient and an applying method thereof. The zinc-rich fruit tree ground nutrient is prepared from 60-70 parts of water soluble zinc fertilizer, 10-15 parts of sparingly soluble zinc fertilizer, 3-5 parts of chelated zinc, 1-3 parts of microbial fertilizer, 1-2 parts of rare earth, 1-3 parts of humic acid, 5-12 parts of plant growth promoter and 5-10 parts of accessory microelement. Quick-dissolving zinc fertilizer and slow-release zinc fertilizer are contained simultaneously, consideration is given to both timeliness and long effectiveness, the zinc-rich fruit tree ground nutrient is evenly sprayed at the root of a fruit tree in a staged mode, which promotes fruit development, increases the yield, and reduces plant diseases and insect pests. The zinc-rich fruit tree ground nutrient and the applying method thereof have the advantages of mainly solving the problem of zinc deficiency during fruit planting; not only can zinc be supplemented fast, but also the zinc fertilizer can be continuously provided within a period of time after application by adopting a formula of combining the soluble zinc fertilizer and the slow-release zinc fertilizer; the zinc-rich fruit tree ground nutrient contains a growth regulator which promotes cell division of plants and increases the plant yield; the formula is reasonable, the yield increasing effect is obvious, and the quality of fruits is improved.

Description

technical field [0001] The invention relates to the field of trace fertilizer research, in particular to a zinc-rich fruit tree ground nutrient and an application method thereof. Background technique [0002] Zinc is mainly used as a metal activator of enzymes in plants. The earliest zinc-containing metalloenzyme discovered is carbonic anhydrase, which is widely distributed in plants and mainly exists in chloroplasts. It catalyzes the hydration of carbon dioxide and promotes the fixation of carbon dioxide in photosynthesis. Zinc deficiency reduces the activity of carbonic anhydrase. Therefore, zinc is important for the formation of carbohydrates. Zinc also participates in the synthesis of auxin (indole acetic acid) in plants. When zinc is deficient, the auxin content in plants decreases, growth and development stagnate, stem nodes shorten, plants are short, and leaf extension and elongation are blocked. , forming leaflets, and in leaf clusters. Pale green, yellow or whit...

Problems solved by technology

[0005] The existing fruit tree fertilizers are all compound fertilizers, which contain a variety of trace elements, but have not been finely divided, and lack targeted supplements, resulting in some trace elements exceeding the actual needs of fruit trees, which will have a negative impact on the quality of the fruit. How to use them accurately and efficiently Trace elements are a topic worth studying
