Production process for desert soilization promotion material

Abstract

The invention discloses a production process for a desert soilization promotion material. The production process is performed through the following operation steps: 1, crushing serpentine to a size of30 to 50 mm through a cone crusher, and transporting crushed serpentine to a ball mill production area for subsequent usage; 2, selecting and purchasing lime with a CaO content of larger than 85% anda particle size of 30 to 50 mm, and transporting the lime to the ball mill production area for subsequent usage; 3, adding the crushed serpentine and the lime into a mill according to a mass percentage ratio of 70%: 30%, carrying out grinding through the mill until the fineness of a ground material is 200 meshes or more, then carrying out discharging, after completion of discharging, and carryingout magnetic separation through a magnetic separation belt conveyor with a volume of 0.2 T so as to separate most of Fe2O3, NiO, CoO, Fe3O4 and Cr2O3, with the remaining being fine powder which is applied as a desert soilization material; and 4, selecting an area for to-be-planted plants on desert soil, applying 300 to 400 kg of the fine powder per mu, then carrying out rotary tillage and sowing,and performing normal cultivation.

Description

technical field [0001] The invention belongs to the field of desert soil control, and relates to a production process for promoting desert soil transformation materials. Background technique [0002] The problem of soil desertification is a worldwide problem. Once the land is deserted, it will cost a lot to restore it to an oasis and arable soil. The technical problems of desert soilization focus on the following aspects: (1) The desert area is dry and water-scarce all year round. Even if there is occasional rainfall, the sand will not have the function of water storage and water retention, so that the rainwater will either be lost through the surface or through the air. evaporation. (2) Due to the large pores of sand and gravel, even if there is groundwater under the sand layer, water cannot be transported to the surface of the ground through capillary action, so most plants cannot survive in the desert. (3) The water source in the desert area has a high degree of mineral...

(2) Due to the large pores of sand and gravel, even if there is groundwater under the sand layer, water cannot be transported to the surface of the ground through capillary action, so most plants cannot survive in the desert

[0005] According to the above literature, we can see that in the current desert control, there is no process of using minerals as desert soil materials.
