The invention discloses a phosphate-solubilizing fungus for promoting the growth of corn and a screening and identification method thereof, and specifically relates to the technical field of microorganisms. The deposit address of the species is: China Type Culture Collection Center, and the sequence of the phosphate-solubilizing fungus is shown in SEQ.No1. The invention provides a separation and screening method for promoting the growth of phosphate-solubilizing fungi of corn, obtaining a single colony that dissolves both organic phosphorus and inorganic phosphorus, and also provides a DNA extraction and identification method for promoting the growth of phosphate-solubilizing fungi on corn. The phosphate-solubilizing fungus has the ability to dissolve phosphate, tolerate salt and alkali, and has a good growth-promoting effect on maize. The root weight, stem and leaf weight, SPAD value and nitrogen content of the control group were significantly different, among which the SPAD value, nitrogen content of the second leaf and the difference of nitrogen content of the third leaf were obtained. |
