Improver for desert planting and improving method

Abstract

The invention further provides an improver for desert planting. The improver is characterized by being formed by mixing, by mass, 70-80% of seaweed with colloid, 10-15% of clay and 10-15% of super absorbent resin, the seaweed is 200-600 meshes, the clay is 100-600 meshes, and the super absorbent resin is 200-400 meshes. The invention further provides an improving method for desert planting. Seaweed and clay which are small granules are used, so that sand gaps can be filled well; the clay is water-impermeable while the seaweed has high cohesiveness, thereby being capable of bonding the clay, the super absorbent resin and sand grains together, so that water retaining ability of surface-layer sand land is improved, seepage is reduced, and sand fixing effect is realized; volume change of the super absorbent resin during water storage and release enables improved sand land to be free of hardening due to cohesion and to still have high air permeability.

Description

Technical field: [0001] The invention relates to the technical field of desert planting, in particular to an improving agent and an improving method for desert planting. Background technique: [0002] my country's desert area is large, and the area is still expanding. In the semi-desert area and the area adjacent to the desert, how to effectively return the sand to the field to protect / expand the cultivated land area is of great significance. [0003] Vegetation needs water. Since the desert has high evaporation and high water seepage rate, the center of traditional sand control is how to retain water. In recent decades, the development of water-retaining materials, such as superabsorbent resins, has taken desert water retention a big step forward. [0004] However, due to the large gaps between the sand grains, the simple use of superabsorbent resin materials solves the problem of water retention, but a large amount of irrigation water still leaks out. During actual cultiv...

Problems solved by technology

[0004] However, due to the large gaps between the sand grains, the simple use of superabsorbent resin materials solves the problem of water retention, but a large amount of irrigation water still leaks out. During actual cultivation, the applied fertilizer leaks due to leaching. and wasted very badly

In addition, the pure use of superabsorbent resin materials cannot play a role in sand fixation, and the surface sand and water-retaining materials may be scraped away, which can neither play a role in water retention nor fix plants
