Problems solved by technology

[0003] In terms of agriculture, due to the effects of over-planting, soil erosion, and excessive application of chemical fertilizers, fertile soil in my country has become less and less, and barren soil is increasing. Barren soil is easy to harden, has poor permeability, low fertilizer efficiency, and poor arability. It is rich in elements needed by the soil, such as sulfur, calcium, silicon, magnesium, iron, sodium, potassium, phosphorus and other beneficial ingredients. It can be used to modify barren soil with appropriate amount of modifiers to cultivate landscaping crops and greening projects, which can make full use of barren soil. Industrial solid waste is consumed while soil resources are used, but the use of phosphogypsum in the soil affects the material cycle of the soil itself, exceeding its own capacity, which will cause soil pollution

Abstract

The invention belongs to the technical field of soil improvement, and particularly relates to agricultural gypsum powder and a method for improving barren soil by using the same. The agricultural gypsum powder is used for improving the barren soil, and the improvement method comprises the following steps: 1) treating the barren soil by using a soil bactericide through spraying or irrigating or mixing; 2) spreading crushed straw and the agricultural gypsum powder on the surface layer of the soil together, watering until the soil is wet, and carrying out ploughing; 3) spreading animal waste anda decomposition agent on the surface layer of the soil and carrying out deep ploughing; and 4) decomposing for 30-60 days, ploughing 2-3 times in the decomposing period, and meanwhile, irrigating until the improved soil is kept moist. An industrial by-product phosphogypsum is fully utilized, nutrient elements contained in the phosphogypsum are utilized to improve the barren soil, and pollution ofthe phosphogypsum to the barren soil is prevented.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to an agricultural gypsum powder and a method for improving barren soil. Background technique [0002] Gypsum is industrial solid waste, which has the characteristics of large output and many impurities, which greatly limits the scope of application of gypsum. At present, the main application of gypsum is reflected in building materials, cement products, chemical products, agriculture, etc.; in agricultural applications Among them, phosphogypsum is the most used one. Because phosphogypsum contains elements such as phosphorus, calcium, magnesium, iron, silicon, and sulfur needed by crops, it can supplement mineral elements in the soil, improve the soil environment, reduce the amount of fertilizer applied, and eliminate soil The hard shell on the surface reduces the viscosity of the soil, increases the permeability of the soil, and prevents and crop diseases. Ther...
