Soil conditioner for desert and gobi regions and application method of soil conditioner

Abstract

The invention discloses soil conditioning granules for desert and gobi regions. Each granule comprises a water absorption layer, a fertilizer layer, a compound bacteria layer and a sand stabilizationlayer in a weight ratio of 1: (3-5): 1: (2-4) from outside to inside, the sand stabilization layer is prepared from the following raw materials in percentage by weight: 13 to 23 percent of modified Sa-son seed gum, 75 to 85 percent of a super absorbent resin and 2 percent of an adhesive; wherein the modified Sa-son seed gum is prepared by stirring carboxymethyl Sa-son seed gum and an organic silicon coupling agent, and the weight of the organic silicon coupling agent accounts for 1-2.5% of that of the carboxymethyl Sa-son seed gum; the raw materials of the fertilizer layer at least comprise one of a compound bacteria nutrient and a plant fertilizer, and also comprise an adhesive; the composite bacteria layer is prepared from composite bacteria powder and an adhesive. By arranging a multi-layer granular structure, the fertilizer and the probiotics are uniformly released and distributed in the soil, and the desert soil is improved and solidified according to a reasonable sequence; a reasonable use method is adopted, a soil environment most suitable for microorganism growth, fertility distribution and subsequent plant growth is created, and very good sand stabilization and water retention effects are achieved; the dosage is small, and the required irrigation water is little.

Description

technical field [0001] The invention belongs to the field of soil improvement, in particular to a soil improver in the Gobi desert area. Background technique [0002] China has a huge area of ​​desertified land, covering Xinjiang, Inner Mongolia, Gansu, Qinghai, Shaanxi and other regions. Land desertification has gradually reduced the land area of ​​our country and caused a serious decline in land productivity. Therefore, desertification prevention and control has become one of the most severe and urgent tasks facing our country. my country's desertification area is large, the ecology is fragile, the desertification soil consumes a lot of water and the planting effect is poor, and the prevention and control of soil desertification is very difficult. To develop a method that can change the loose particles of desertification soil, lack of aggregate structure, improve water retention and fertilizer retention, and increase organic matter. It is very important for the prevention ...

Problems solved by technology

However, this method is very cumbersome, has very high requirements on the selection of soil amendments, construction methods, etc., and has low reproducibility, and the effect of planting crops or forest trees on the treated soil is limited.
