Ferment leaf fertilizer for green vegetables and preparation method of ferment leaf fertilizer

Abstract

The invention specifically discloses ferment leaf fertilizer for green vegetables. The ferment leaf fertilizer can improve the absorption rate of a leaf surface for nutrients, promotes photosynthesis, enables the leaf to grow vigorously, and has an antibacterial insect repelling efficacy. The ferment leaf fertilizer is prepared by mixing a solution A and a solution B according to a weight ratio of 1: (1.0 to 1.3), the pH value of the mixed solution is adjusted to 6.0 to 6.5 by adding acid, wherein the solution A is prepared by fermenting the following components for 3 to 5 months at a temperature of 25 to 35 DEG C and removing the ferment residues: brown sugar, sodium chloride, silkworm excrement, tea seed cake, fresh fruits and vegetable residues, water, activated EM flora and bacillus aceticus; and the solution B is prepared by adding water to the following components to 100 parts: biochemical fulvic acid type B, sugar alcohol, urea, boric acid, ammonium sulfate, zinc sulfate, magnesium sulfate, manganese sulfate, ferrous sulfate, ammonium molybdate, potassium dihydrogen phosphate and a penetrating agent.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizer processing and utilization, in particular to an enzyme foliar fertilizer for green leafy vegetables and a preparation method thereof. Background technique [0002] Although there are more than 700 kinds of foliar fertilizers officially registered in my country, there are still many problems in these foliar fertilizer products. The first is the wrong judgment on the standard of foliar fertilizer. From the perspective of leaf color and growth, the effect on improving yield and quality is often ignored; in terms of products, there are many problems: many products are "traditional" and have single nutritional elements. The application effect has not been achieved, and most of the modern research results have not been followed up. For example, the compatibility of nutrient elements is not paid attention to, the proportion is unscientific, or the content of nutrient elements is low, the ...

Problems solved by technology

The first is the wrong judgment on the standard of foliar fertilizer. From the perspective of leaf color and growth, the effect on improving yield and quality is often ignored; in terms of products, there are many problems: many products are "traditional" and have single nutritional elements. The application effect has not been achieved, and most of the modern research results have not been followed up. For example, the compatibility of nutrient elements is not paid attention to, the proportion is unscientific, or the content of nutrient elements is low, the water solubility is poor, and the mobility in plants is poor; too much attention is paid to the application of growth regulators. Ignoring the improvement of nutrient absorption rate; no foliar additives, or inappropriate types of foliar additives, low leaf spread and penetration; do not pay attention to impurities and toxicity of medium and trace elements, such as high content of accompanying elements, heavy metal content Exceeding the standard; poor protection for medium and trace elements, selenium and rare earth elements, the type of chelating agent used is inappropriate or is a large molecule, which directly affects the effective absorption rate of nutrients, etc.
