Embodiment Construction

[0031] The present invention is further described below in conjunction with embodiment.

[0032] The effect of each component of the present invention is as follows:

[0033] Vermiculite: It is a layered structure of magnesium-containing hydroaluminosilicate secondary metamorphic minerals, usually formed from black (golden) mica through hydrothermal alteration or weathering, and has high heat insulation and frost resistance and other performance. Available in the market.

[0034] Diatomaceous earth: It is a kind of siliceous sedimentary rock, mainly composed of algae remains of single-celled aquatic plants called diatom water, with special porous structure, light weight, heat insulation, strong adsorption, low abrasiveness, and chemical stability Advanced advantages. As a lightweight insulating material and absorbent in formulations. Available in the market.

[0035] Soil: It is a highly hydrophilic substance that increases in volume when it meets water, forming a thixo...

Abstract

The present invention relates to an atomization agent instead of agricultural plastic mulch film, which is characterized by that it uses vermiculite, diatomaceous earth, ban soil, microcrystal cellulose, yellow clay, cotton pump residue, pregelatinized starch, PVA and water as raw material, respectively adopts the processes of pulverizing, drying and hydrolysis treatment to make them into suspended emulsified liquor, and adopts atomization method to spay it on the soil surface to form protecting shell layer with the actios of antifreezing, raising temp., temp.-insulating, drought-resisting, preserving soil moisture and increasing fertilizer effect, and good air permeability and antiscouring property.

Description

technical field [0001] The invention relates to a soil covering agent. Background technique [0002] The application of plastic film mulching cultivation technology has greatly improved the yield of crops, and the economic and social benefits are very significant. However, with the increase in the use of plastic mulch, its negative effects have gradually emerged. First of all, the residual film in the cultivated land gradually forms a barrier layer, which affects the growth and development of crop roots and the absorption of water and fertilizer, reducing crop yield. Experts predict that if this happens for more than 20 years, the output will drop by 15-20%. If the accumulation of plastic mulch per mu reaches more than 34 kg, the land will lose its productive capacity. Secondly, it is difficult to recycle plastic mulch. According to estimates, about 1 / 3 of the amount of plastic mulch used remains in the soil, causing damage to the land structure, and the recycled residual ...
