Abstract

The invention belongs to the technical field of oil improvement, and especially relates to a soil improvement agent. The soil improvement agent is prepared from, by weight, 20 to 25 parts of dolomite powder, 19 to 22 parts of flyash, 13 to 16 parts of powdered rock phosphate, 12 to 15 parts of peat, 8 to 10 parts of food residue, 7 to 9 parts of polypropylene glycol, 6 to 10 parts of humic acid, 5 to 8 parts of livestock manure, 4 to 8 parts of leguminous green manure, and 0.5 to 1 part of dendrobium. The soil improvement agent is reasonable in formula, is capable of improving soil physical structure effectively, reducing soil volume weight, improving soil water content, changing soil chemical properties, adjusting all conditions or a part of conditions including soil water, fertilizer, gas, and heat, and improving soil fertility.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a soil improver. Background technique [0002] At present, the world has 730 million hm of arable land 2 , but an average of nearly 5 million hm per year 2 of the land is too degraded to produce food. By 2050, the world's nearly 600 million hm 2 of land desertification, about 2 million hm 2 Salinization of irrigated land. my country's land resources are even less optimistic. On the one hand, the development of urbanization has occupied a large amount of high-quality cultivated land. On the other hand, soil erosion has continued to intensify. The annual loss of nutrients is equivalent to 1 / 2 of the current total national fertilizer production. Nearly 33 million hm of desertified land in the north 2 . The grassland degraded area is about 87 million hm 2 , and with 1.2 million hm per year 2 The speed of left and right expands. The area of ​​polluted cultivated lan...
