Functional ecological potash fertilizer for agriculture and preparation method thereof

Abstract

The invention relates to a functional ecological potash fertilizer for agriculture and a preparation method thereof. The potash fertilizer comprises nutrition ingredients like potassium, calcium, magnesium, and a plant nutrition conditioner (containing multiple organic acids like gamma-polyglutamic acid, and microelements like iron, zinc, manganese, boron, molybdenum and the like). The functional ecological potash fertilizer for agriculture is prepared through uniformly mixing all raw materials according to the demand and prilling, has complete nutrition, has the pH greater than or equal to 7, has high use ratio, can be well absorbed, becomes effective rapidly, can regulate the pH value of the soil, effectively improves the soil so as to improve the yield and quality of the crops, reduces input of fertilizers, saves plant cost for farmers, and protects the ecological environment. According to the requirement of soil measurement and fertilization, the potash fertilizer has remarkable effects no matter the potash fertilizer is individually used or used with other fertilizers by mixing.

Description

technical field [0001] The invention relates to a functional agricultural ecological potassium fertilizer and a preparation method thereof, in particular to a multifunctional agricultural potassium sulfate and potassium chloride with large particle pH ≥ 7, which can improve soil and protect the environment, and a preparation method thereof. Background technique [0002] Fertilizers are the grain of crops (grain). my country consumes 32% of the world's total output of chemical fertilizers, and the amount of fertilizer per unit area is more than three times the world's average level. According to statistics, the amount of chemical fertilizers used in 2012 exceeded 60 million tons, and the actual amount was 160 million tons. 9% of the total, but the amount of fertilizer application accounts for more than 30% of the global total, which can be called a superpower of fertilization, which brings about low fertilizer use efficiency, decreased soil fertility, and soil acidification, r...

Problems solved by technology

3) Due to the exchange of bases, K+, Ca2+, and Mg2+ on acidic soil colloids are replaced by H+, which enter the soil solution and are lost, resulting in the lack of potassium, calcium, and magnesium nutrients

4) At the same time, soil acidification activates heavy metal elements, such as: cadmium, mercury, lead, chromium, aluminum, etc., resulting in a decline in the quality of agricultural products
