Description
Technical Field
The invention belongs to the technical field of microbial preparations, and particularly relates to a corn growth-promoting, probiotic and biocontrol bacterial fertilizer integrated preparation and a preparation method thereof.
Background
The Gansu province climate has the characteristics of southeast moistening, middle drought and northwest high cold, so that the planting quantity of middle and late maturing corn varieties is large, the growth period is long, and the environmental conditions and the phenological period are prolonged to create a good living environment for pest and disease damage; on the other hand, the corn in Hexi province is continuously planted for years, so that the disease residues and the pathogenic bacteria source base number in soil are increased in an accumulated mode, and soil-borne diseases are widely spread due to excessive application of nitrogen fertilizers and flood irrigation.
The corn diseases become the most main problems of yield reduction and income reduction of the corn planting industry in China, and the economic benefits of farmers are damaged. Chemical control can prevent and control the disease rate of corn diseases in a wide range within a very short time, but the chemical control has the problems of drug resistance of germs and insect pests, excessive pesticide residue, serious environmental pollution, threat to human health and the like. Biological control avoids a series of problems in plant protection, environment, energy, health and the like caused by the use of chemical pesticides.
Microbial preparations have a plant growth promoting effect and plant growth is improved by plant rhizosphere or symbiotic microorganisms producing plant hormones, such as: indoleacetic acid, gibberellin, cytokinin, ethylene, and the like; microorganisms produce vitamins such as: nicotinic acid, pantothenic acid, biotin, VB12 and the like, which are coenzymes or prosthetic groups of various enzymes in organisms; the growth process of the microorganism secretes nucleic acid substances, promotes the absorption of phosphorus and potassium by the roots of the plants, and enhances the photosynthesis of the plants. The microorganism converts inorganic trace elements which are not easy to be absorbed by the plant into organic trace elements which are easy to be absorbed, and the absorption of nutrition by the plant is promoted; some inducers secreted by the microorganisms improve the activity of soil enzymes, are beneficial to the transformation of soil nutrients and improve the absorption of plants to the nutrients.
The microbial preparation has biocontrol effect on plants, including antagonism, and biocontrol bacteria can be obtained by secreting antibacterial substances, such as: antibiotics, bacteriocins and other antibacterial proteins, etc., change the living environment, thereby inhibiting the growth of pathogenic bacteria; the method has the advantages that the method has a heavy parasitic effect, active substances secreted by biocontrol strains are identified by pathogenic bacteria, the biocontrol bacteria tightly wind pathogenic bacteria hyphae, and the cell walls of the pathogenic bacteria are degraded by secreting extracellular hydrolases, so that the hyphae are broken or disintegrated, and the growth of the pathogenic bacteria is hindered; competition effect, biocontrol bacteria are planted in the plant body and rapidly propagated, and a large amount of nutrition is consumed in the process, so that the pathogenic bacteria are lack of nutrition to inhibit growth; the induction of resistance and the excitation of biocontrol bacteria to the potential disease resistance of plants can play a role in preventing diseases.
The composite microbial preparation has better functionality than a single microbial preparation, 3 functional microorganisms including plant growth promoting microorganisms, probiotic microorganisms and biocontrol microorganisms are screened out and compounded with the functional microorganisms to prepare the preparation, and metabolites and various bioactive factors of the preparation are compounded, so that the function of the composite microbial preparation is diversified, and the stability of the preparation is enhanced.
