Method for preparing compound inoculants by decomposing non-water soluble potassium-containing shale with torulaspora globosa

Abstract

The invention discloses a method for preparing compound inoculants by decomposing non-water soluble potassium-containing shale with torulaspora globosa. The method comprises the following steps: torulaspora globosa (ACCC ID: 20321) is used for decomposing non-water soluble potassium-containing shale in a liquid fermentation medium so as to obtain a leachate containing potassium, phosphorus, sulfur, magnesium, calcium, zinc, copper and other minerals needed for plants; the leachate is mixed with a concentrated EM liquid according to a volume ratio of 2: 1 so as to obtain the compound inoculants which mainly contain mineral element potassium and further contain phosphorus, sulfur, magnesium, calcium, zinc and copper. According to the method, non-water soluble potassium-containing minerals are used as the raw materials to alleviate the situation of lack of potash fertilizer resources in our country and reduce the cost; meanwhile, the method is low in pollution and energy consumption and is expected to have good economic and social benefits.

Description

technical field

[0001] The invention relates to a method for preparing a composite microbial agent by using Torula spores to decompose water-insoluble potassium-containing shale, in particular to a method for preparing compound bacteria containing various plants by using Torula spores to decompose water-insoluble potassium-containing shale The method of the compound bacterial agent of the required mineral elements. Background technique

[0002] Potassium fertilizer is one of the three commonly used fertilizers that are indispensable in agricultural activities. In recent years. The amount of potassium fertilizer application in my country has been on the rise, but the storage of soluble potassium mineral resources in my country is low, which cannot meet the needs of growing agriculture, and the contradiction between supply and demand is prominent. Therefore, how to increase the supply of potassium fertilizer in our country has become an urgent problem to be solved. In my co...
