Abstract

The invention relates to the technical field of soil improvement, in particular to a soil improver for sandy soil of a dry land. The soil improver is prepared from the following components: rice huskcharcoal, peat, coal humic acid, kaolin, loosening agent, high-performance moisturizing agent, nutrition supplementing agent and composite amino acid, wherein the loosening agent is coal ash or talcumpowder; the high-performance moisturizing agent is prepared by compounding a porous carrier and water absorption resin by virtue of a special process, so that compared with the traditional polyacrylamide, the water absorption performance is higher, and the water retention performance is better; and the soil improver is good in combination effect with sandy soil, can improve the clustering effectof the sandy soil, can avoid the soil loss, and can significantly improve the water retention performance of the soil of the dry land.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a soil conditioner for dry sandy soil. Background technique [0002] With the increase of my country's population, the advancement of urbanization and the improvement of people's material living standards, the basic farmland has already experienced soil compaction and salinization due to high-load planting. This problem will lead to a sharp decline in farmland productivity. production rate is reduced. In order to solve this problem, my country has carried out a variety of farmland protection measures such as returning farmland to forest, returning farmland to grassland, fallow, and crop rotation in vast rural areas, which has greatly alleviated the degradation of farmland soil quality in my country. [0003] However, due to the low per capita arable land share in my country, large-scale reforestation, grazing and fallow will affect my country's grain production. Grain pr...
