Desert improver and processing technology thereof

Abstract

The invention provides a desert improver, which can realize water and fertilizer retention, provide multiple mineral nutrients like phosphorus, potassium, calcium, magnesium and silicon required by plant growth, and solve the soil fertility problem during planting development or at the early stage of planting restoration. The desert improver is suitable for vegetation damage or degradation causedby over grazing, excessive deforestation, grassland reclamation and continuous farming or other human factors under certain rainfall or irrigation conditions, or restoration and desertification process reversal of desert or immobile sand that is located on the edge of the desert or around oasis and serves as the foundation of a planting field parcel, and can realize a planting effect fitting waterand fertilizer resource conditions. The desert improver is prepared from the following raw materials by mass: 18-30 parts of phosphate ore; 3-10 parts of potassium mica; 2-4 parts of bentonite or expanded vermiculite; 2-5 parts of illite; 35-60 parts of coal gangue; 2-5 parts of an organic fertilizer; and 1-2 parts of wood flour.

Description

technical field [0001] The invention relates to the technical field of desert transformation, in particular to a desert improving agent and a processing technology thereof. Background technique [0002] Human factors such as overgrazing, deforestation, grassland reclamation and continuous farming have caused vegetation damage or degradation, exposed ground, and accelerated wind or rain erosion, which is an important cause of desertification. From the perspective of the impact of human activities on land degradation in the Asia-Pacific region, vegetation destruction accounts for 37%, overgrazing accounts for 33%, unsustainable agricultural cultivation accounts for 25%, and over-development of infrastructure construction accounts for 5%. The main impact of desertification is: the decline of land productivity and the subsequent reduction of agricultural and animal husbandry production, which will bring corresponding economic losses and a series of social consequences. In extrem...

AI Technical Summary

Problems solved by technology

[0003] Among all kinds of deserts, some are non-flowing sandy lands with certain precipitation, and some have certain irrigation conditions, such as those located on the edge of deserts and around oases, have certain water sources, and have become the basis for planting fields, but the soil particles in these places are relatively coarse , it is not easy to store water, retain water and store fertilizers. Because of the large particle gap and serious water evaporation, it often cannot provide a variety of mineral nutrients needed for plant growth, such as phosphorus, potassium, calcium, magnesium, silicon, etc.
