Abstract

The invention discloses a coal ash soil improver and a preparation method thereof. The soil improver comprises the following components in parts by weight: 30 to 50 parts of coal ash, 20 to 30 parts of ageratina adenophora, 10 to 18 parts of ammonium sulfate, 3 to 6 parts of monoammonium phosphate, 8 to 16 parts of vinasse, 8 to 15 parts of bentonite, 10 to 14 parts of urea formaldehyde, 4 to 8 parts of monopotassium phosphate, 12 to 18 parts of chicken manure, 6 to 10 parts of earthworm manure and 1 to 2 parts of a composite microbial agent. The improver prepared by the method has remarkableimprovement and repair effects on the degraded soil, can increase the organic matter content of the soil, increase the living bacteria count of the soil, improve the granular structure of the soil, improve the acidity and the alkalinity of the soil, improve the soil buffer capability and the water-retaining and fertilizer-retaining capability, maintain the ecological balance of the soil, fix radioactive elements in the soil, reduce migration of the radioactive elements, reduce the potential ecological risk and relieve pollution of the radioactive elements of the soil, and has a wide market application prospect.

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...
