Bacterial preparation capable of decreasing soil-borne diseases, accelerating rooting and resisting continuous cropping

Abstract

The invention relates to the technical field of biotechnology, in particular to a bacterial preparation capable of decreasing soil-borne diseases, accelerating rooting and resisting continuous cropping. The bacterial preparation is prepared from the following raw materials in parts by weight: 2 to 15 parts of humic acid, 0.1 to 15 parts of amino oligosaccharide, 0.1 to 2 parts of naphthyl acetic acid, 0.2 to 10 parts of indolebutyric acid, 0.1 to 20 parts of DA-6, 0.2 to 10 parts of zinc, and bacillus lichens with 0.02 to 50 billion spores / gram. The bacterial preparation has the advantages that the soil-borne diseases are decreased, the crop rooting is quickly accelerated, the growing and strengthening of seedlings are accelerated, the transplanting survival rate is improved, the green return speed is quick, the disease-resistant property is realized, and the yield is increased by 5 to 8% or above.

Description

technical field [0001] The invention relates to the technical field of biotechnology, in particular to a fungal preparation capable of alleviating soil-borne diseases, promoting rooting and resisting heavy cropping. Background technique [0002] Biotechnology is the use of science and biotechnology to transform agriculture or other aspects. Bacterial preparations are a common application of biotechnology in agriculture. Bacterial preparations are live microbial preparations made from normal microorganisms or substances that promote the growth of microorganisms. [0003] Continuous cropping disease (also known as continuous cropping disease) refers to the disease caused by the long-term cultivation of the same crop in the same field, including physiological diseases caused by the imbalance of soil nutrients caused by continuous cropping, and diseases caused by severe pathogenic bacteria. pathological disease. [0004] In recent years, the contradiction of more people and le...

Problems solved by technology

[0007] 1. Continuous cropping (heavy cropping) causes an increase in pathogenic bacteria in the soil: crops grow in the same place for a long time, some pathogenic microorganisms such as Fusarium remain in the soil or plant residues and multiply in large numbers, and the base number increases year by year; , susceptible to disease;

[0008] 2. The selective absorption of crops causes the imbalance of nutrient supply: the selective absorption of crops causes the imbalance (deficiency) of nutrient supply, leading to the deficiency of nutrients, especially the lack of some trace elements;
