Description

technical field

[0001] The invention relates to the field of agricultural microorganisms, in particular to a rhizosphere growth-promoting bacterium capable of dissolving phosphorus, producing NH3, producing plant growth hormone and producing siderophile and its isolation and screening method. Background technique

[0002] According to statistics, the current consumption of chemical fertilizers per unit area in my country is three times the world average level, ranking first in the world. Due to the extensive application of chemical fertilizers, a large amount of chemical nutrients in the cultivated soil has accumulated, and problems such as soil acidification and secondary salinization have become more and more prominent. Environmental security and food safety pose serious threats. Improve the production technology mode of excessive application of chemical fertilizers and pesticides in the current agricultural production, improve the soil structure, increase the number and ...
