Liquid fertilizer and preparation method therefor

Abstract

The invention discloses a liquid fertilizer and a preparation method therefor. The liquid fertilizer is prepared from the following raw materials, by weight, 10-20 parts of microbial fermentation broth, 130-210 parts of urea, 145-205 parts of water-soluble ammonium polyphosphate, 150-200 parts of potassium phosphate, 45-70 parts of potassium nitrate, 20-50 parts of potassium chloride, 3-60 parts of ammonium dihydrogen phosphate, 3.5-6.5 parts of boric acid, 5-10 parts of chelating zinc, 4-8 parts of chelating iron, and 365-420 parts of water. The liquid fertilizer has a high nutrient content and can be absorbed by crops directly, absorption and utilization of the fertilizer is raised, capabilities of drought resistance, high temperature resistance, cold resistance, disease resistance, salt resistance, lodging resistance and the like of crops are raised, and the liquid fertilizer has obvious effects on stable yield and high yield of crops and keeping of excellent characteristics of varieties and is suitable for modern agricultural fertilizer application technology.

Description

technical field [0001] The invention relates to a liquid fertilizer, in particular to a large-element liquid fertilizer and a preparation method thereof, belonging to the field of fertilizers. technical background [0002] At present, the international fertilizer consumption is developing in the direction of high concentration and liquefaction. Water-soluble fertilizer is one of the key areas in the development of new fertilizers. It has the functions of instant dissolution, easy absorption, complete nutrients, high utilization rate, water saving, environmental protection, and convenient use. It can be applied to sprinkler irrigation, drip irrigation and soilless cultivation to realize water and fertilizer Integration to achieve the effect of saving water, fertilizer and labor, especially in the production of facility agriculture with great potential. Water-saving agriculture is an inevitable trend in the development of sustainable, ecological and environmentally friendly a...

AI Technical Summary

Problems solved by technology

Although solid water-soluble fertilizers can be quickly dissolved in water, they are prone to moisture absorption and caking, incomplete dissolution, and insufficient mixing. The absorption rate of crops is not very fast, and the absorption rate and utilization rate are limited. The fertilizer efficiency of the fertilizer is not fully utilized, resulting in the lack of nutrients in the crops, the imbalance of nutrients in the crops, causing physiological diseases, resulting in frequent occurrence of various bacterial and fungal diseases, and heavy losses

[0004] Although the existing liquid fertilizer also has many advantages such as convenient use, non-toxic, harmless, non-polluting, fast absorption speed, etc., its formula structure is unreasonable, and its nutrition and disease resistance are not strong, especially for wheat that is prone to lodging and mild white powder. disease, high-sensitivity wheat rust, head blight and many other diseases, there is no liquid formula fertilizer with excellent control effect
