Embodiment Construction

[0008] The preferred embodiments of the present invention's compound fertilizer for activating soil to condition saline-alkali land without deep plowing and its preparation method will be described in detail below.

[0009] The compound fertilizer for activating soil conditioning saline-alkali land without deep plowing is made from the following raw materials in weight percentage: 40% desulfurized gypsum, 6% potassium chloride, 11% potassium sulfate, 8% monoammonium phosphate, 25% urea, and 10% humic acid , and Bacillus subtilis 0.2 billion / g.

[0010] Desulfurization gypsum is also known as exhaust gas desulfurization gypsum, sulfur gypsum or FGD gypsum. The main component is the same as natural gypsum, calcium sulfate dihydrate CaSO4·2H2O, with a content of ≥93%. Desulfurization gypsum is a by-product of the FGD process, a technology that uses lime-limestone to recover sulfur dioxide from coal or oil flue gas.

[0011] Potassium chloride is a colorless elongated rhombohedra...

Abstract

The invention discloses a compound fertilizer capable of activating soil, regulating saline-alkali soil and avoiding deep tillage and a preparation method thereof and relates to the field of agricultural fertilizers. The compound fertilizer capable of activating soil, regulating saline-alkali soil and avoiding deep tillage is convenient in application, can be spread or sprayed, can achieve effectsof regulating and improving soil, improving soil fertility and reducing saline-alkali degree, has phosphorus / potassium-dissolving effects and excellent nitrogen fixation effect and also has multipleeffects of inhibiting bacterium reproduction, improving soil aggregate structure, promoting acting root development, improving the fertilizer utilization rate and the like.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers. More specifically, the invention relates to a compound fertilizer capable of activating soil and regulating saline-alkali land without deep plowing and a preparation method thereof. Background technique [0002] China has a large population, but the area of ​​cultivated land is relatively small, and the soil has a lot of saline-alkali land, especially in Xinjiang and other places in China. Protecting the ecological environment, improving soil fertility, reducing the use of chemical fertilizers, and increasing the organic matter of cultivated land are the top priorities in realizing the fertile soil engineering plan, which is of strategic significance for promoting sustainable agricultural development and regulating and improving soil compaction and salinity. Existing compound fertilizers for saline-alkali soil use relatively traditional raw materials and outdated manufacturing techniques...
