Modified-rice-straw soil modifier capable of preventing and curing pests and pathogens

Abstract

The invention discloses a modified-rice-straw soil modifier capable of preventing and curing pests and pathogens. The soil modifier is made from the following raw materials, by weight part, 16-18 of pine needles, 8-10 of tamarind seed polysaccharide gum, 26-27 of rapeseed meal, 34-36 of traditional Chinese medicine residue, 5-7 of a pyroligneous liquor, 6-8 of ammonium dihydrogen phosphate, 3-4 of boric acid, 55-60 of rice straw, 2.2-2.4 of monochloro acetic acid, 13-15 of kaolin, 5-6 of calcium-based bentonite and a proper amount of water. In the soil modifier, raw materials, such as traditional Chinese medicine residue and pine needles, having the function of resisting pests and killing pathogens, are adopted, so that the environment of resisting pests and pathogens is formed in shallow soil. The soil modifier has a preferable auxiliary effect on planting crops in the modified soil. The soil modifier develops the function of the modified soil and reduces pesticides used in the later. The soil modifier provides a good environment and has good economic benefit.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a modified rice straw soil modifier capable of preventing insect fungi. Background technique [0002] my country's agriculture is relatively developed, and it is a large agricultural country with a long history. A large amount of agricultural solid waste is produced every year, such as sugarcane dregs, rice husks, rice and wheat straw, etc. These agricultural solid wastes are often not comprehensively utilized in a timely manner, and are dumped and incinerated indiscriminately, causing huge pollution to the environment. The use of low-quality agricultural solid waste as raw material for soil improvement has become a research hotspot in the field of high-quality solid waste utilization and environmental restoration. Through simple physical or chemical treatment of these solid wastes, the adsorption performance of heavy metals and organic pollutants in the soil can be imp...
