Application of nitrogen fixation bacterial manure to improvement of tea quality

Abstract

The invention relates to application of nitrogen-fixation bacterial manure to improvement of tea quality. The nitrogen fixation bacterial manure is characterized by being prepared from mixing nitrogen-fixation bacteria and a carrier with a weight ratio of 0.1 to 1%, the nitrogen-fixation bacteria is prepared by mixing azorhizobium caulinodans, azomonas winogradsky, A.lipoferum according to a weight ratio of (3 to 5) to (2 to 4) to (1 to 2). according to the invention, the nitrogen-fixation bacterial manure is applied to the planting of tea, the content of amino acid and caffeine in tea can beimproved and the quality of tea is obviously improved.

Description

technical field [0001] The invention belongs to the technical field of tea planting, and in particular relates to the application of nitrogen-fixing bacterial fertilizer in improving the quality of tea, which can be used in tea planting. Background technique [0002] Tea originated in China and is one of the three major beverages in the world. There are many kinds of tea, which can be divided into: fully fermented tea (black tea), semi-fermented tea (black tea) and non-fermented tea (green tea) according to the degree of fermentation; according to the season of tea production, it can be divided into: spring tea, summer tea, Autumn tea and winter tea; according to the shape of the tea, it can be divided into: loose tea, bar tea, broken tea, garden tea, regular tea, auxiliary tea, brick tea, bunch tea, etc.; Tea, scented tea, bagged tea, and health tea; according to the place of origin, it can be divided into: high mountain tea, hilly tea, Longjing tea, etc. Generally speaki...

Problems solved by technology

At the same time, the soil structure is poor, there are few soil microorganisms and soil animals, the permeability is not good, and the performance of water and fertilizer retention is poor.

Due to the lack of reasonable planning and layout in the development of tea gardens, steep slopes and full slopes are developed for tea plantation, without supporting ecological protection forests and street trees, the soil management adopts the traditional clear tillage mode, and green manure is not planted alternately, and "three light" measures are implemented for the tea garden to look good; Extensive use of chemical pesticides not only kills pests, but also kills soil animals such as birds, spiders, frogs, natural enemies insects and earthworms; excessive application of chemical fertilizers, especially N fertilizers, leads to deterioration of soil structure, soil The reduction of animals and microorganisms makes the yield of tea leaves relatively low and the quality relatively poor
