Problems solved by technology

[0007] At present, although various probiotics are used to produce microbial foliar fertilizers and abamectin is used to prepare biopesticides, there are relatively extensive and in-depth studies, but the combination of probiotics and abamectin is used as an effective way to promote plant growth and prevent pests. However, there is no report on the new micro-ecological foliar fertilizer

specific Embodiment approach

[0017] The technical solutions of the present invention will be further described below in conjunction with specific embodiments.

[0018] The principle of the invention is that the probiotic culture contains bacteria cells and metabolites thereof, which have the functions of stimulating plant growth and metabolism, and alleviating and preventing diseases. Abamectin is a kind of biological insecticide, acaricide and nematocide mainly with gastric toxicity and contact action. It paralyzes and kills pests by hindering the transmission of pest motor nerve signals; it has high efficiency, low toxicity, It has the advantages of no pollution, long-lasting drug effect, not easy to produce drug resistance, and no cross-resistance with other pesticides. The micro-ecological foliar fertilizer produced by mixing the probiotic culture and avermectin according to a certain ratio combines the advantages of probiotics and their metabolites to improve plant growth and abamectin’s effective pe...

Embodiment 1

[0020] First, the respective fermentation cultures to obtain cell concentrations of 18.2 billion / ml Bacillus natto, 15.7 billion / ml Lactobacillus, 10.3 billion / ml Rhodopseudomonas palustris and 2.8 billion / ml Saccharomyces cerevisiae, such as attached figure 1 As shown, the cell concentration of 18.2 billion / ml Bacillus natto 100ml, 15.7 billion / ml Lactobacillus 100ml, 10.3 billion / ml Rhodopseudomonas palustris 100ml and 2.8 billion / ml Saccharomyces cerevisiae 100m were mixed, and then Adding 0.5‰ of Abamectin, the total cell concentration obtained is 11.75 billion / ml, and the content of Abamectin is 0.5‰ of micro-ecological foliar fertilizer, as attached figure 2 shown. In the experimental group, the micro-ecological foliar fertilizer composed of 4 kinds of probiotics and 0.5‰ abamectin was diluted 100 times with water, and sprayed evenly on the leaves of rapeseed once every 7 days. , and the control group was sprayed with the same dose of water. After 40 days of growth, ...

Embodiment 2

[0022] Firstly, the cell concentrations of Bacillus natto, 15.7 billion / ml, 10.2 billion / ml Rhodopseudomonas palustris and 2.5 billion / ml Saccharomyces cerevisiae were obtained by fermentation respectively. , mixed according to the proportions of 15%, 15%, 45% and 25% respectively accounting for the total volume percentage, and then added 0.2‰ of abamectin to obtain a total cell concentration of 10.23 billion / ml, and the abamectin content 0.2‰ micro-ecological foliar fertilizer.

Abstract

The invention discloses a preparation method of a microbial-ecological foliar fertilizer promoting plant growth and controlling pest. The method comprises the following steps: separately cultivating bacillus, lactic acid bacteria, rhodopseudomonas palustris with the cell concentration of over 10 billion / ml and a bacteria liquid of yeast with the cell concentration of over 2 billion / ml; and mixingthe mixed solution of the four kinds of probiotics with abamectin of a certain proportion to obtain the liquid microbial-ecological foliar fertilizer with the total cell concentration of over 8 billion / ml. The method disclosed by the invention has the advantages that: all strains adopted are edible probiotics of human beings, safe and nontoxic; abamectin is a macrolides insecticidal antibiotic agent, and has the characteristics of high efficiency, low toxicity, no pollution, lasting effect and the like; the prepared microbial-ecological foliar fertilizer integrates the advantages of probiotics in promoting plant growth and abamectin in efficient pest control; the microbial-ecological foliar fertilizer is diluted with water for 100 times and sprayed onto the leaf surfaces of the plant every other 7-10 days; and the microbial-ecological foliar fertilizer not only obviously increases the plant yield by over 30%, but also can control plant pest, thereby having important application value.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular provides a method for preparing micro-ecological foliar fertilizers for promoting plant growth and preventing pests by using probiotics and abamectin. Background technique [0002] Foliar fertilizer refers to the fertilizer that is applied to the leaves of the plant and can be absorbed and utilized by it. Since the foliar fertilizer can directly enter the plant body from the leaves and participate in the metabolism of the plant and the synthesis of organic matter, the absorption capacity of the root system is weak at the later stage of plant growth and development. When needed, the nutrients needed can be supplemented in time. As a representative of emerging fertilizers, foliar fertilizers can improve the yield and quality of crops, and its research and application have attracted more and more attention. [0003] Foliar fertilizer originated in France, since 1884 botanist Grisb put...
