A kind of sand control method of degradable integrated fertilizer planting soil

Abstract

The invention discloses a sand control method for degradable integrated fertilizer planting soil. The method includes: 1. adding a polymer water-soluble bio-based binder and a binder solution prepared by water to a water-soluble fertilizer containing humic acid, The fertilizer seed soil mixture composed of grass seeds and sandy soil is mixed to obtain prefabricated fertilizer seed soil aggregates; 2. Preparation of natural polymer material solution and cross-linking agent solution; 3. Spraying the cross-linking agent solution on the surface of the prefabricated fertilizer seed soil aggregate The semi-finished product of prefabricated fertilizer seed soil aggregate; 4. The semi-finished prefabricated fertilizer seed soil aggregate is added into the natural polymer material solution to obtain the fertilizer seed soil gel; The invention utilizes the water absorption and water retention properties of the gel to provide humidity and temperature conditions for grass seeds, improves the survival rate of grass seeds, solves the problem that grass seeds are not easy to grow due to poor water and fertilizer retention performance in sandy land and large temperature difference, and is suitable for degradation Governance of grassland, moving sand, semi-moving sand and fixed sand.

Description

technical field [0001] The invention belongs to the technical field of sand control, and in particular relates to a sand control method for degradable integrated fertilizer planting soil. Background technique [0002] Land desertification refers to the phenomenon that the topsoil loses fine particles (silt, clay) and gradually becomes sandy due to soil erosion, or due to the intrusion of quicksand (sand), the content of organic matter in the land is reduced, and the productivity is reduced or even lost. The causes of land desertification include natural factors such as climate, as well as human activities such as overgrazing, deforestation, land reclamation, rodent damage, and unreasonable use of water resources. [0003] The common methods of controlling land desertification include fencing and natural restoration, grass squares for sand fixation and grass cultivation, and liquid plastic film, all of which have good control effects. However, the cycle of fencing is long, t...

Problems solved by technology

In this method, the natural polymer water-absorbing material gel is coated on the prefabricated fertilizer soil aggregate composed of humic acid water-soluble fertilizer, grass seeds and sandy soil to form a fertilizer soil gel, and the water absorption and water retention characteristics of the gel are utilized. Provide continuous and stable humidity and temperature conditions for grass seeds, improve the survival rate of grass seeds, and solve the problem that grass seeds are not easy to grow due to lack of soil structure, poor water and fertilizer retention performance, and large temperature difference in sandy land. It is used for sand control in degraded grassland, mobile sand, semi-mobile sand and fixed sand
