Embodiment 1

[0022] This embodiment provides a composition for preventing bacteria and removing pesticide residues in tea, which is prepared by the following steps: weighing 5% of organophosphorus hydrolase HT976, 5.0% of pyrethroid hydrolase HT986, 3.0% of After the trehalose was fully mixed, 1.0% rhamnolipid, 0.5% Paeonia suffruticosa bark extract, 0.1% citric acid were sequentially added, and the balance was made up with water, and the pH of the composition was 5.85.

Embodiment 2

[0024] This embodiment provides a composition for preventing bacteria and removing pesticide residues in tea, which is prepared by the following steps: weighing 30.0% organophosphorus hydrolase HT976, 30.0% pyrethroid hydrolase HT986, 20.0% pyrethroid hydrolase HT986 by mass percentage After the trehalose was fully mixed, 8.0% of sophorolipid, 10% of Cortex Moutan extract, and 2.0% of tromethamine were sequentially added, and the pH of the composition was 7.92.

Embodiment 3

[0026] This embodiment provides a composition for preventing bacteria and removing pesticide residues in tea, which is prepared by the following steps: weighing 15.0% of organophosphorus hydrolase HT976 enzyme solution and 15.0% of pyrethroid hydrolase HT986 enzyme solution by mass percentage and 10.0% trehalose were mixed thoroughly, followed by adding 4.0% trehalose lipid, 5% Paeonia suffruticosa bark extract, 2.0% citric acid, the balance was made up with water, and the pH of the composition was 5.46.

Abstract

The invention belongs to the technical field of crop cultivation, and particularly provides a composition for preventing germs and removing pesticide residues for tea, which comprises the following components in percentage by mass: 5.0 to 30.0 percent of organophosphorus hydrolase HT976, 5.0 to 30.0 percent of pyrethroid hydrolase HT986, 3.0 to 20.0 percent of trehalose, 1.0 to 8.0 percent of bioglycolipid, 0.5 to 10.0 percent of moutan bark extract and 0.1 to 2.0 percent of acid-base regulator, the pH value is 5.0 to 9.0, and the balance of water. The balance is water or maltodextrin. The composition provided by the invention has the advantages that the components are safe and free of toxic and side effects, the problems of preventing and treating germs of tea trees, increasing the tea yield, removing pesticide residues in soil and the like in the picking period of small camellia and rice field tea can be solved, and the pesticide removing effect on tea is improved.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a composition for preventing pathogenic bacteria and removing pesticide residues from tea, and a preparation method and application thereof. Background technique [0002] The commonly used pesticidal pesticides diafenthiuron, chlorpyrifos, bifenthrin, and herbicide glyphosate are all applied to the soil or sprayed on the leaves of the tea leaves after the tea leaves are diseased. Rice field tea, with seasonal regular pests and diseases, is used to control tea leafhoppers (springworms), arch-backed insects, carbon maggot diseases, tea cake diseases, etc. After a while, bacterial diseases and insect pests will appear drug resistance, and the applied pesticides The amount of pesticides will gradually increase, and over time the residual pesticides will not only pollute the soil water quality, but also easily endanger human health. [0003] Most of the existing ...
