Biofertilizer leavening agent for improving strawberry rhizosphere soil ecological structure

Abstract

The invention relates to a biofertilizer leavening agent for improving a strawberry rhizosphere soil ecological structure. The biofertilizer leavening agent is characterized by comprising 40-60 partsof pseudomonas oryzihabitans, 20-30 parts of saccharomycetes, and 20-30 parts of bacillus subtilis. The pseudomonas oryzihabitans is preserved in China General Microbiological Culture Collection Center (CGMCC) which is located in No.3, No.1 courtyard, Beichen West Road, Chaoyang District, Beijing, the preservation number is CGMCC No.15325, and the preservation data is Jan. 29, 2018. Bacterial manures prepared by the leavening agent can better colonize at the root of the strawberry, is safe and reliable, can decompose autotoxin in soil of continuous cropping strawberries, improves physical andchemical properties of soil remarkably, promotes stress tolerance of strawberry plants, increases yield and improves quality of strawberries.

Description

technical field [0001] The invention relates to the field of repairing microorganisms and continuous cropping obstacles, in particular to a biological bacterial fertilizer starter for improving the ecological structure of strawberry rhizosphere soil. Background technique [0002] Strawberries contain a variety of vitamins and 17 kinds of amino acids, as well as calcium, iron, phosphorus, zinc and other minerals, which are very popular among consumers. Yield and quality have seriously affected the income of growers. Strawberry is a kind of herbaceous crop. It is susceptible to diseases during the growth period, and there are many kinds of diseases. If it is planted in the same field for a long time, harmful microorganisms and soil-borne pathogens will gradually accumulate, which will easily cause the breeding and spread of diseases and insect pests, and the more harmful the plant infection will be. If the disease becomes more and more serious, the growth of the plant will be...

AI Technical Summary

Problems solved by technology

At present, there are relatively few probiotics applied to strawberry continuous cropping obstacles, and most of them use fungicides and chemical fertilizers for soil treatment, which leads to problems such as soil compaction and acidification, nutrient imbalance, and secondary salinization. The lack of safe and effective biological bacteria treatment seriously restricts melons The governance and sustainable development of crop continuous cropping obstacles have become one of the bottleneck problems that need to be solved urgently in the agricultural production of melon crops

[0004] At present, the planting area of ​​edible fungi in my country is expanding rapidly. After the cultivation of edible fungi, a large amount of fungus residues are produced. Some mushroom farmers discard the fungus residues in the ditch and on the road at will, which not only causes waste of resources, pollutes the environment, but also It is more likely to be infected by diseases and insect pests, which will harm the normal growth of edible fungi

Even some industrialized production enterprises pile up the fungus residue for a long time in order to sell the fungus residue at a better price, which not only pollutes the environment, but also breeds diseases and insect pests and spreads quickly. It is easy to be infected with diseases and insect pests, and the quality of the produced fungus products will also be affected

The crop straw and cottonseed hulls in the edible fungi cultivation material are rich in lignin, cellulose, etc., and some of them are absorbed and utilized by mycelia. Hydrocarbons and trace elements can be used as good organic fertilizers for vegetable cultivation, but edible fungus residues cannot be completely absorbed by plants without fermentation treatment, and will instead destroy the original nutritional structure of the soil, resulting in unbalanced nutritional components, resulting in The phenomenon of root damage caused by the obstruction of plant root absorption
