AI Technical Summary

Technical Problem

Anji white tea gradually re-green at above 20℃, resulting in a shortening of the picking period and a decrease in yield.

Method used

Using the organic fertilizer prepared by the potassium-detoxified Bacteria Panraburkholderia sp.AnNong-1, the soil microbial community is regulated and the chlorophyll synthesis of tea trees is inhibited, thereby delaying the greening of Anji white tea.

Benefits of technology

It significantly delays the return time of Anji white tea, increases the picking period, increases the yield and economic value of white tea, and delays the return time of at least 5 to 10 days, which can basically increase the yield of white tea by more than 30% for the tea garden.

Abstract

The invention provides a method for delaying greening of Anji white tea, and belongs to the technical field of tea planting, the method comprises potassium bacteria organic fertilizer for delaying greening of Anji white tea, the potassium bacteria organic fertilizer mainly comprises vinasse and rape seed cakes, and the specific preparation method comprises the steps that the vinasse and the rape seed cakes are fully and evenly mixed according to the mass ratio of 5: 5-7: 3, and the moisture content is adjusted to be 45-55%; and adding 0.2-3% of potassium bacteria, and fermenting for 2-4 weeks under the conditions of normal temperature and ventilation to obtain the potassium bacteria organic fertilizer. The potassium bacteria organic fertilizer is applied to soil of a tea garden from September to December in the first year, and afforestation of Anji white tea can be delayed in spring in the second year. The method is low in cost and simple in preparation process, fertilization is also a traditional fertilization method, afforestation of the Anji white tea can be effectively delayed, the picking amount of the Anji white tea is increased, and the economic value of the Anji white tea is increased.

Claims

1. A use of potassium-solubilizing bacteria, the Latin name of the potassium-solubilizing bacteria is: Panraburkholderia sp. AnNong-1, deposited in China Center for Type Culture Collection, with the accession number: CCTCC M 2021242, is characterized by: The potassium-dissolving bacteria are used to prepare potassium-dissolving bacteria organic fertilizer for delaying the greening of Anji white tea.

2. A method for preparing an organic fertilizer for delaying the greening of Anji white tea and dissolving potassium bacteria, characterized in that: The steps include: ① Prepare fresh distiller's grains with a moisture content of 55-65% and rapeseed cake with a moisture content of 20-30%; ② Mix the distiller's grains and rapeseed cake in a mass ratio of 5:5 to 7:3 to obtain mixture I; ③ Adjust the moisture content of mixture I to between 45% and 55%; ④ Add 0.2-3% potassium-solubilizing bacteria Panraburkholderia sp. AnNong-1 to the mixture I in step ③ according to the mass ratio and ferment for 2-4 weeks under normal temperature and ventilation conditions to obtain potassium-solubilizing bacteria organic fertilizer.

3.
