Crop bacterial preparation capable of mitigating soil-borne disease, promoting rooting, resisting continuous cropping

Abstract

The invention relates to the technical field of biotechnology, in particular to a crop bacteria preparation capable of mitigating soil-borne disease, promoting rooting, resisting continuous cropping,which is prepared from the following raw materials in parts by weight: 2-20 parts of humic acid, 0.2-10 parts of indolebutyric acid, 0.2-10 parts of naphthylacetic acid, 0.2-10 parts of zinc, 0.2-5 parts of iron, and 0.02-10 billion spores / trichoderma mycetes or trichoderma mycetes, the bacteria preparation disclosed by the invention can mitigate disease, promote rooting of crop, strengthen rice seedling, improve survival rate of transplanting, turn green quickly, resist diseases, increase production by 5-8% or above.

Description

technical field [0001] The invention relates to the technical field of biotechnology, in particular to an agricultural crop fungus 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...

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;
