Abstract

The invention discloses a soil modifier prepared by using phosphogypsum and a preparation method thereof. The soil modifier is prepared from, 30-40 parts of the phosphogypsum, 60-80 parts of limewater, 20-30 parts of eupatorium adenophorum, 3-7 parts of coconut powder, 12-20 parts of rapeseed dregs, 6-10 parts of humic acid, 8-16 parts of pig manure, 2-3 parts of compound amino acid liquid, 5-9 parts of plant ash, 0.1-0.5 part of zinc sulfate monohydrate, 2-4 parts of polyacrylamide, 8-14 parts of ammonium tribasic phosphate and 1-2 parts of complex microbial community. According to soil modifier, by using the phosphogypsum to prepare the soil modifier, the environmental pollution problem brought by the accumulating of of the phosphogypsum can be effectively solved, and the prepared soil modifier can obtain better economic benefit.

Description

technical field [0001] The invention relates to the field of agricultural technology, and also relates to the field of environmental protection technology for utilizing waste, in particular, to a soil conditioner prepared from industrially produced waste and a preparation method thereof. Background technique [0002] At present, chemical pesticides pose a threat to the sustainable development of agriculture. Chemical fertilizers and pesticides are widely used in agricultural production. A large amount of agricultural chemicals such as chemical fertilizers, pesticides and herbicides have been invested, the irrigation area has continued to expand, and the intensity of soil mechanical operations has continued to increase. The introduction of new crops, crop fertilizer-resistant varieties and continuous innovation of cultivation techniques have jointly promoted the rapid increase of global agricultural production. At the same time, chemical agriculture has also brought serious e...
