Embodiment 1

[0023] The use effect of embodiment 1 on Anxi Tieguanyin tealeaves

[0024]Before spring tea picking and after the last pesticide spraying, according to the amount of 50 kg / ha, 7 to 14 days before each harvest, dilute the fungal agent 15-20 times and spray it on the surface of the tea tree plant once. Dried tea was prepared by the same tea-making process with and without bacterial agent, and the two kinds of dried tea were tested and compared at the same time for quality and chemistry. The test report shows that compared with the control tea without using the bacterial agent, the water extract content of the tea using the bacterial agent has increased by 5.0% (from 35.9% to 37.7%), and the tea polyphenols have increased by 7.0% (from 19.9%). % increased to 21.3%), amino acids increased by 20% (from 1.5% to 1.8%), EGCG increased by 7.4% (from 3.53% to 3.79%), GCG provided 6.8% (from 3.08% to 3.29% ), the total amount of catechins increased by 3.6% (from 13.07% to 13.54%), whic...

Embodiment 2

[0025] The use effect of embodiment 2 on paddy rice

[0026] At the booting stage of rice and after the last spraying of pesticides, when the pests have been controlled, spray the bacterial agent once each time. According to the dosage of 45 kg / ha each time, the bacterial agent is properly diluted and sprayed on the surface of the rice plant. The use effect report on rice shows that compared with the control rice without bacterial agent, the content of various amino acids and crude protein has been improved in varying degrees: aspartic acid has increased by 23.0% (by 23.0%) 0.52% increased to 0.64%), threonine increased by 23.8% (from 0.21% to 0.26%), serine increased by 36% (from 0.25% to 0.34%), glutamic acid increased by 33.6% (from 0.98 % increased to 1.31%), proline increased by 21.4% (from 0.28% to 0.34%), glycine increased by 24% (from 0.25% to 0.31%), alanine increased by 23.5% (from 0.34% increased to 0.42%), valine increased by 20.5% (from 0.39% to 0.47%), isoleucin...

Embodiment 3

[0027] The use effect of embodiment 3 on Chinese cabbage

[0028] Before the pak choy is picked and after the last pesticide spraying, when the pests have been controlled, spray on the surface of the pak choy plants 7 to 14 days before each harvest at an amount of 60 kg / ha. The report on the application effect on pakchoi shows that the pakchoi with the bacterial agent has beneficial changes in various growth indexes and nutritional indexes. Compared with the Chinese cabbage without bacterial agent, fresh weight increased by 25%, dry weight increased by 11%, chlorophyll a increased by 36%, chlorophyll b increased by 11%, and carotenoids increased by 11%. 39%, soluble sugar increased by 48%, soluble protein increased by 31%, vitamin C increased by 9%.

Abstract

The invention relates to the application of pesticide residue degradation bacteria of pyrethroid on modifying the crop quality, belonging to microbiological fertilizer field. It takes the pesticide residue degradation bacteria strain LFJS3-9 as bacteria for production, dilutes it for 15-20 times according to consumption of 30-75kg / hectare, and sprays on crop surface or to soil in a sunny day. It is usually used after the last pesticide utilization, and the effect would be better if used many times or during crop best growing period. It is determined that said bacteria contains many kinds of nutritional components. The invention is characterized by low cost for production and utilization, dramatic crop quality modification, suitability for farm product production and processing in modern agricultural production, and the utilization can be widely spread on industrial crop such as tea and vegetable and cereal crop such as rice.

Description

1. Technical field [0001] The invention relates to the application of pyrethroid pesticide residue degrading bacteria to improve the quality of crops, belongs to the field of microbial fertilizers, is a method of using microorganisms to improve soil and improve the quality of crops, and is suitable for the production and processing of high-quality agricultural products in modern agricultural production. 2. Technical background [0002] my country's agriculture has gone through more than 5000 years of history. Traditionally, farmers' planting and animal husbandry are closely combined, and the application of organic fertilizers maintains the balance of soil nutrients, follows the natural operating laws of ecosystem processes, and ensures the sustainable development of agriculture. However, since the 1950s, the growing population has urgently required the use of new agricultural technologies such as chemical fertilizers, pesticide inputs, and improved new varieties to produce m...
