Balanced water-soluble fertilizer containing humic acid and preparation method thereof

Abstract

The invention discloses a balanced water-soluble fertilizer containing humic acid and a preparation method thereof. The balanced water-soluble fertilizer is prepared from the following raw materials:monoammonium phosphate, potassium nitrate, urea, humic acid, ferrous sulfate, zinc sulfate, magnesium sulfate, a microelement chelating agent and complexing elements. The preparation method comprisesthe following steps: raw material weighing, uniform mixing, smashing, uniform stirring and filling. The balanced water-soluble fertilizer is full water-soluble, chelated, high in activity and reasonable in nutrient proportion, and can quickly supplement various nutrients required for crops. The soil can be improved, the propagation of effective microbial community is promoted, and the acidity andalkalinity of soil are effectively adjusted. The balanced water-soluble fertilizer is rich in humic acid, the root growth is promoted, the content of leaf chlorophyll is increased, the photosyntheticefficiency is improved, the yield is increased, the picking period is advanced, and the picking time is prolonged. The organic powder fertilizer provided by the invention is excellent in performance,low in cost and moderate in chelating constant, and can effectively solve the problem that the contradiction between the preparation of the fertilizer and crop balanced absorption is balanced.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a balanced humic acid-containing water-soluble fertilizer and a preparation method thereof. Background technique [0002] my country is the world's largest producer of chemical fertilizers. Although the arable land area is less than 10% of the global total, the amount of chemical fertilizers used is close to 1 / 3 of the global total. However, excessive use of chemical fertilizers not only reduces soil fertility rapidly, but also seriously affects crop quality. , but also pollute the environment and seriously damage the ecological environment. Humic acid fertilizer adds humic acid that is beneficial to the land and crops into a single chemical fertilizer, and has gradually become a new direction for fertilizer production. However, the humic acid water-soluble fertilizer currently sold on the market is liquid humic acid fertilizer, or a small amount of nitrogen. Phos...

[0002] my country is the world's largest producer of chemical fertilizers. Although the arable land area is less than 10% of the global total, the amount of chemical fertilizers used is close to 1 / 3 of the global total. However, excessive use of chemical fertilizers not only reduces soil fertility rapidly, but also seriously affects crop quality. , but also pollute the environment and seriously damage the ecological environment

Humic acid fertilizer adds humic acid that is beneficial to the land and crops into a single chemical fertilizer, and has gradually become a new direction for fertilizer production. However, the humic acid water-soluble fertilizer currently sold on the market is liquid humic acid fertilizer, or a small amount of nitrogen. Phosphorus and potassium liquid fertilizers. These simple humic acid water-soluble fertilizers cannot meet the normal growth needs of plants due to their low nitrogen, phosphorus, and potassium content. Moreover, the existing humic acid water-soluble fertilizers are easy to produce due to unreasonable process parameters during production. A large amount of biuret is produced, resulting in production failure
