Nutrient soil capable of improving stony desertification region and production method thereof

Abstract

The invention provides nutrient soil capable of improving a stony desertification region and a production method thereof and belongs to the field of stony desertification treatment. The nutrient soilis prepared by, by weight, 8-15 parts of plant straw, 10-20 parts of peat soil, 30-50 parts of viscose loam, 12-21 parts of coconut coir, 7-18 parts of pond sludge, 30-45 parts of potassium acrylate,7-18 parts of anhydrous magnesium sulfate, 10-20 parts of aloe extract, 2-10 parts of crosslinking agent, 1-7 parts of initiator, 15-25 parts of livestock manure and 5-10 parts of yeast powder. The nutrient soil and the production method thereof have the advantages that the water absorption rate of the nutrient soil is increased; water-retaining components in plant fibers allow the nutrient soil to be high in water retaining performance, and the nutrient soil can slowly supply water for plant roots under a dry and water-shortage environment condition; the nutrient soil is capable of providingbasic nutrition for plant growth, easy in raw material obtaining, simple in production method, good in stony desertification region treatment effect and capable of saving stony desertification regiontreatment cost.

Description

technical field [0001] The invention relates to the technical field of rocky desertification control, in particular to a nutrient soil for improving rocky desertification areas and a preparation method thereof. Background technique [0002] Rocky desertification is also called rocky desertification. It refers to the phenomenon of loss of surface soil, bare bedrock, loss of agricultural use value of land and degradation of ecological environment due to soil erosion. Rocky desertification mostly occurs in limestone areas, the thickness of the soil layer is mostly less than 10cm, and the surface presents an evolution process of gradually exposing rocks similar to desert landscapes. In terms of causes, the main factor leading to rocky desertification is human activities. Due to the continuous destruction of natural vegetation for a long time, large areas of steep slopes have been reclaimed, resulting in exposed ground, coupled with thin soil layers in karst rocky mountainous a...

AI Technical Summary

Problems solved by technology

The southwest karst area has a special geological background, strong landscape heterogeneity, strong karst action, and small ecological environment capacity. However, the population is large, and the sharp human-land conflict has led to increasingly serious vegetation damage and soil erosion, resulting in very serious rocky desertification. And it shows a trend of continuous expansion, leading to aggravation of poverty in rocky desertification areas and affecting sustainable economic and social development
