Protective cultivation method of tea garden

Abstract

The invention discloses a protective cultivation method of a tea garden and belongs to the technical field of horticultural plant cultivation. The method comprises the steps of applying mulch to the tea garden with straw plants or growing plants or combination of straw plants and growing plants in May, and ditching between lines of tea trees before the mulch and applying base fertilizer mixed by farmyard manure, potassium sulphate for agricultural use, regular calcium superphosphate and urea; and applying urea in small holes near the tea trees once in May of the next year. According to the protective cultivation method of the tea garden, contents of organic matter, soil alkali-hydrolyzable nitrogen, available phosphorus and available potassium in top soil are improved fast after three months, soil acidity is adjusted, soil environment is improved, the water content of soil is greatly improved, water and soil loss is reduced, tea quality is improved, the soil structure in the tea garden is changed, the fresh leaf yield ratio is increased by 11.3-15.6% comparatively, income is increased, and protective cultivation and sustainable development of the tea garden are achieved.

Description

technical field [0001] The invention relates to a protective cultivation method for tea gardens, belonging to the technical field of horticultural plant cultivation. Background technique [0002] At present, more than 40 countries at home and abroad, such as France, China, Canada, Spain, Brazil, Australia, Japan, etc., have conducted research on protective cultivation techniques, focusing on rice, corn, wheat, beans, potatoes, sugarcane, rape and other crops. Mainly, most of them focus on food crops, and less in tea garden production. The main key technical problems lie in the selection and matching of covering materials and species, supporting fertilization technology, and the inability to balance short-term and long-term benefits of tea gardens. [0003] The tea garden suffers from severe soil erosion and poor nutrition, the tea trees grow thin and the yield is low. The causes of soil erosion in tea gardens are tea gardens built on steep slopes, long-term unreasonable fa...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the existing tea garden production that adopts the mode of plowing and turning the soil several times a year, and the ground is exposed to cultivation and management, which leads to serious water and soil loss in the tea garden all the year round, increases in the amount and frequency of use of chemical fertilizers and pesticides, poor nutrients, and tea tree growth. Thin, low-yield defects and deficiencies, and provide a tea garden that can effectively reduce soil erosion, promote effective use of soil nutrients, vigorous growth of tea trees, increase tea production, increase tea garden biodiversity, reduce environmental pollution, save costs and labor Investment, leading the tea industry to a low-carbon, sustainable and healthy development of tea garden protective cultivation methods
