Abstract

The invention belongs to the fields of agriculture, an agricultural technology and bacillus application, and relates to bacillus megaterium H3 and application thereof in promoting crop growth and reducing absorption of heavy metal by crops. The bacillus megaterium H3 is adopted as a raw material, and is subjected to bacteria activation so as to prepare into a bacterial suspension. The bacillus megaterium H3 bacterial suspension is inoculated in heavy metal contaminated soil, so that the rice growth can be promoted, and the cadmium content in rice grains is reduced. When a passivator and the bacillus megaterium H3 bacterial suspension are complex-used in the heavy metal contaminated soil, the vegetable growth can be promoted, the vegetable quality is improved, and the cadmium content of edible parts of vegetables is reduced.

Description

technical field

[0001] The invention belongs to the field of agricultural technology and the application of bacillus, and relates to bacillus megaterium H3 and its application in promoting crop growth and reducing crop absorption of heavy metals. Background technique

[0002] With the rapid development of industry and the widespread use of pesticides and chemical fertilizers, cadmium pollution in farmland soil in my country has become increasingly serious. Rice is an important food crop in my country. Heavy metal cadmium accumulates in rice roots, stems, leaves and grains, which not only affects rice yield, quality and the entire farmland ecosystem, but also seriously endangers the health of animals and humans through the food chain. In recent years, farmland contaminated soil remediation technologies represented by passivation (stabilization), phytoremediation, and bioremediation are currently a good choice for the remediation of moderately and lightly polluted soil and he...
