Liquid bacterial agent capable of reducing soil-borne diseases, promoting rooting and resisting continuous cropping

Abstract

The invention relates to the technical field of biotechnology, in particular to a liquid bacterial agent capable of reducing soil-borne diseases, promoting rooting and resisting continuous cropping. The liquid bacterial agent is prepared from the following raw materials in parts by weight: 3 to 20 parts of amino acid, 0.01 to 1 part of brassinolide, 0.2 to 20 parts of pyrimidine nucleoside antibiotics, 0.2 to 10 parts of indolebutyric acid, 0.1 to 10 parts of naphthylacetic acid, 0.2 to 10 parts of zinc and 0.2 to 10 parts of magnesium. The bacterial agent disclosed by the invention can achieve the effects of reducing the soil-borne diseases, promoting fast rooting of vegetables, promoting the growth of strong seedlings and improving the transplanting survival rate, and has the advantagesof fast green returning and disease resistance; the yield is increased by 5 to 8 percent or higher.

Description

technical field [0001] The invention relates to the technical field of biotechnology, in particular to a liquid bacterial agent that can reduce soil-borne diseases, promote rooting and resist continuous cropping. Background technique [0002] Biotechnology uses 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] Repeated cropping disease (also known as continuous cropping disease) refers to the diseases caused by the long-term cultivation of the same crop in the same plot, including the physiological diseases caused by the imbalance of soil nutrients caused by continuous cropping and the serious occurrence of pathogenic bacteria. Pathological disease. [0004] In recent years, the contradiction between more people and less lan...

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;
