Abstract
A Penicillium simplicissimum sp. nl-z1 strain for promoting growth of root nodules and increasing abundance of probiotic microorganism population is disclosed. The Penicillium simplicissimum sp. nl-z1 strain can promote Indigofera pseudotinctoria Matsum. production and nodule growth, and improve probiotic microorganisms and nutritional environment. After the application of Penicillium simplicissimum sp. nl-z1, the nutrient elements needed by plants such as potassium, calcium and magnesium in rock powder are effectively released, the fusion of spraying matrix and rock surface is promoted, the nutrition is continuously supplied for plants, the total nodule weight is increased by 152.63%, the content of hydrolyzed nitrogen is improved by 15.28%, and the symbiotic nitrogen fixation ability is effectively exerted. At the same time, the relative abundance of Mortierella in soil is increased from 12.81% to 94.95%, and the increasing amount of Mortierella and its promoting effect on plants are better than that of direct application of Mortierella.
