Sandy soil conditioner

Abstract

The invention provides a sandy soil conditioner. The sandy soil conditioner is prepared from, by weight, 80 parts to 100 parts of organic fertilizer, 20 parts to 40 parts of high-hydroscopicity resin, 10 parts to 15 parts of humic acid, 3 parts to 5 parts of sepiolite, 8 parts to 10 parts of smectite powder and 15 parts to 18 parts of hydroxyapatite. According to the sandy soil conditioner, as the proportion of the organic fertilizer, the high-hydroscopicity resin, the humic acid, the sepiolite, the smectite powder and the hydroxyapatite is reasonably set, the problems that sandy soil is loose in structure and barren, and does not have fertilizers are effectively solved, and the material conditions required by growth of crops and vegetation can be improved.

Description

technical field [0001] The invention relates to a soil improver, in particular to a sandy soil improver. Background technique [0002] my country is one of the countries most seriously harmed by desertification in the world. The large area and wide distribution of desertification have threatened human survival and development space, leading to a serious decline in land productivity, exacerbating the deterioration of the ecological environment, causing serious economic losses, and affecting food security. pose a threat. Therefore, it is of great practical significance to explore practical techniques and methods for improving sandy soil. [0003] At present, the sandy soil amendments currently used are mainly direct application of organic fertilizer or peat soil, and the improvement effect is poor. Although direct application of organic fertilizer and peat soil as soil amendments can improve the fertility of sandy land, it can only temporarily improve soil fertility but not s...

Problems solved by technology

[0003] At present, the sandy soil amendments currently used are mainly direct application of organic fertilizer or peat soil, and the improvement effect is poor.

Although direct application of organic fertilizer and peat soil as soil amendments can improve the fertility of sandy soil, but because it has no water retention function, it can only temporarily improve soil fertility but not soil properties.
