Embodiment 1

[0046] Example 1. A method for preparing field crop production-increasing disease-resistant biological bacterial fertilizer, characterized in that it comprises the following steps:

[0047] Step 1: Protease-producing bacteria, lipase-producing bacteria, cellulase-producing bacteria, amylase-producing bacteria, potassium bacteria, and phosphorus bacteria obtained from the General Microbiology Center (CGMCC) of the China Microbiological Culture Collection Management Committee were respectively prepared according to the provided Bacterial Strain Explanation Carry out activation, step-by-step expansion culture, and prepare bacterial agent. The microbial enzyme activity unit of the international system of units is used as the measurement unit, wherein the cellulase activity unit is based on the FPA activity unit, according to protease: lipase: amylase: The ratio of cellulase=0.5: 0.2: 0.3: 0.8, then add 2% volume ratio of potassium bacteria agent and 5%% volume ratio of phosphorus ...

Abstract

The invention discloses a preparation method of a yield-increasing disease-resistant biological bacterial fertilizer for field crops. The preparation method comprises the following steps: step 1, preparing a first complex microbial inoculant and a second complex microbial inoculant; step 2, screening a plurality of strains from a strain library of verticillium lecanii, beauveria bassiana and metarhizium anisopliae, selecting three fungal strains which have the smallest antagonism with the second complex microbial inoculant obtained in the step 1 from the strains, and carrying out enlarged culture; step 3, preparing a coating agent; step 4, fermenting; step 5, granulating and coating; and step 6, carrying out low-temperature drying in vacuum. The problems that in the prior art, a field biological bacterial fertilizer prepared from plant ash, furfural residues and mushroom dregs does not contain various active microorganisms with different functions, the colonization survival performance of the microorganisms is low, and the disease prevention and insect prevention effects are not achieved can be solved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a method for preparing field crop-increasing and disease-resistant biological bacterial fertilizers. Background technique [0002] Plant (herbaceous and woody plants) residues after burning, called plant ash. Because plant ash is the ashes of plants after burning, plant ash contains almost all the mineral elements contained in plants. Among them, potassium is the most abundant element, generally containing 6-12% potassium, of which more than 90% is water-soluble and exists in the form of carbonate; followed by phosphorus, generally containing 1.5-3%; it also contains calcium, magnesium, silicon, Sulfur and iron, manganese, copper, zinc, boron, molybdenum and other micronutrients. Therefore, it is a natural fertilizer with a wide range of sources, low cost, complete nutrients and obvious fertilizer efficiency. However, because plant ash is alkaline, it cannot be mixed with ...
