Agricultural water-retaining soil-loosening soil conditioner and preparation method thereof

Abstract

The invention discloses an agricultural water-retaining soil-loosening soil conditioner and a preparation method thereof. The conditioner is prepared from the following components: 20 to 55 parts of calcium ammonium nitrate, 0.1 to 10 parts of monoammonium phosphate, 0.1 to 5 parts of ammonium sulfate, 10 to 35 parts of potassium humate, 0.1 to 1 part of polyacrylamide, 0.1 to 3 parts of biological enzyme, 0.5 to 2 parts of magnesium oxide, 2 to 6 parts of potassium fulvate, 5 to 10 parts of bentonite, 5 to 10 parts of light calcium carbonate. The agricultural water-retaining soil-loosening soil conditioner is stable in nature, and can be combined with various means such as improving microecological environment of the soil, loosening compacted soil, and improving physical properties of thesoil, thereby ultimately improving the utilization rate of a fertilizer and yield and quality of crops, and avoiding problems of imbalances in proportion of nutrient elements and changes in soil nutrient structure caused by long-term use of compound fertilizers containing only major elements, and has high social, economic, and ecological benefits.

Description

technical field [0001] The invention relates to the technical field of soil conditioners, in particular to an agricultural soil conditioner for retaining water and loosening soil and a preparation method thereof. Background technique [0002] The normal growth and development of food and commercial crops depends on a good soil environment. The neutral soil environment is most conducive to the growth of most plants, and the overacid and overalkaline environment is not conducive to the normal growth of most plants. According to the national field positioning experiments and surveys conducted by the Soil and Fertilizer Research Institute of the Chinese Academy of Agricultural Sciences in recent years, in the cultivation of major agricultural areas in my country, the increase in grain production mainly depends on the application of large amounts of chemical fertilizers. The massive investment in planting and agrochemicals and the aging of ditch facilities have led to the general ...

Problems solved by technology

[0005] However, in the process of using the above-mentioned conditioner, due to the molecular characteristics of polyacrylamide, a kind of water-soluble linear polymer, it is easy to cause the degradation of polyacrylamide in heat, salt, oxygen (chemical oxidation) environment, making soil loosening The water retention effect is weakened and lasts for a short time, and if you continue to spray pesticides and fertilize in subsequent planting, the improvement effect will not last long
