A kind of biological pesticide that promotes plant growth and improves immunity and preparation method thereof

Abstract

The invention provides a biological pesticide for promoting the plant growth and improving the immunity. The biological pesticide is prepared from the following ingredients in parts by weight: 5 to 10parts of chitosan, 5 to 10 parts of carrageenan oligosaccharide, 10 to 20 parts of oligosaccharins, 20 to 30 parts of ammonium polyphosphate, 20 to 30 parts of itaconic acid, 1 to 5 parts of compoundsodium nitrophenolate, 20 to 30 parts of potassium nitrate and 20 to 30 parts of magnesium sulfate. The biological pesticide provided by the invention has the advantages that the plant growth condition can be enhanced; the plant yield can be increased; the internal quality of the plants can be improved; in addition, good effects of repelling underground pests can be achieved; the plant immunity is enhanced, so that the plant disease resistance and stress resistance characteristics are enhanced.

Description

technical field [0001] The invention relates to the field of fertilizer production, in particular to a biological pesticide for promoting plant growth and improving immunity and a preparation method thereof. Background technique [0002] The fertilizer currently being promoted by the country is an organic-inorganic compound fertilizer. Its standard is based on the general organic fertilizer. It is an improved type of pure chemical fertilizer and is biased towards the characteristics of pure chemical fertilizers. The use effect is not ideal, the improvement effect on the soil is limited, and the organic matter contained in it has not been fermented. The reason is that the current standard sets too low moisture content for compound fertilizers, because in order to meet the standard, the fertilizer must be dried at high temperature during the processing of the fertilizer to meet the standard. Therefore, there is a waste of resources and a shortcoming of increasing costs in thi...

Problems solved by technology

[0002] The fertilizer currently being promoted by the country is an organic-inorganic compound fertilizer. Its standard is based on the general organic fertilizer. It is an improved type of pure chemical fertilizer and is biased towards the characteristics of pure chemical fertilizers. The use effect is not ideal, the improvement effect on the soil is limited, and the organic matter contained in it has not been fermented

The reason is that the current standards set the moisture content of compound fertilizers too low, because in order to meet the standards, the fertilizer must be dried at high temperature during the processing of the fertilizers to meet the standards.

Therefore, there is a waste of resources and a shortcoming of increasing costs in this processing process.

In addition, since the organic matter in the compound fertilizer currently used has not been fermented, after being applied to the ground, the organic matter will ferment in the ground after absorbing water, which may easily cause seedling burn

Moreover, the effective utilization rate of nitrogen, phosphorus and potassium in the fertilizer is low, the fertilizer efficiency is not ideal, and it does not have the effect of preventing and controlling diseases and insect pests.
