Abstract

The invention relates to the technical field of soil amendment and discloses a soil amendment for deserts and beaches. The soil amendment for the deserts and the beaches is prepared from 50-60 parts of crop straw, 10-20 parts of fly ash, 5-6 parts of ground phosphate rock, 12-18 parts of crab shell and 8-12 parts of modified montmorillonite, wherein the crab shell is pretreated, acid and alkali treatment is performed on the crab shell, chitin is obtained, then acrylamide is grafted to chitin, and a hydrophilic polymer is formed; ultra-hydrophilic montmorillonite is obtained from montmorillonite through modification treatment with cocamidopropylamine oxide; a water-retaining agent with an interlayer structure is prepared from chitin and the modified montmorillonite through mixing. The soilamendment can have better fertility improving and water retaining effects on desert soil.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a soil conditioner which can obviously improve the soil quality of desert tidal flats. Background technique [0002] Deserts and desertified lands seriously threaten the living environment of human beings. In the past, the practice of transforming deserts was mainly to plant psammophytes and shelter forests on the edge of deserts, and gradually advance to the hinterland of deserts. Due to the drought and lack of rain in desert areas, the survival rate of sandy vegetation is not high. Although people have adopted various technical means and measures in planting vegetation, the effect is not great. The existence of large areas of desert and desertified land directly leads to the deterioration of air quality and environmental degradation in cities. Sandstorms that have occurred continuously in recent years have brought a large amount of sand to cities. Therefore, how to ma...
