Tea garden weed ecological control method

Abstract

The invention relates to a young tea garden weed ecological control method, which comprises technologies of weed seed selection, seeding time and method selection, seedling period management and the like. The seeding time of autumn tea seedlings is middle and late February of the second year; the spring tea seedling is the spring of the current year. According to the seeding method, after the shallow hoeing in the tea garden, 500g to 750g trifolium repens seeds are seeded in per mu of land, and the seeding is possibly uniform; according to the seedling period management, weeds with the protruding growth condition are manually pulled away in the current seeding year; in late May and early June, according to the growth condition of the trifolium repens, 5 to 10kg of three-element composite fertilizers are spread in rainy days; the ground surface of the tea garden can be fully covered in the current year. The method provided by the invention solves the problem of overgrown weed damage of the young tea garden, and is favorable to the fast growth of tea seedlings, and has the advantages that the tea seedling transplanting survival rate is improved; the management and protection cost of the young tea garden is greatly reduced; the method belongs to an economic simple and convenient young tea garden weed ecological control method.

Description

technical field [0001] The invention relates to an ecological control method for weeds in young tea gardens. technical background [0002] Due to the low coverage of young tea trees and the strong growth of weeds, a little negligence can easily lead to weed shortage, which seriously affects the growth and development of tea trees in newly planted tea gardens. In severe cases, large areas of tea trees are missing or even broken, resulting in a low gardening rate. At present, only manual weeding is the only way to control weeds in young tea gardens. However, manual weeding in young tea gardens is cumbersome and requires careful attention. According to surveys, in general years, newly planted tea gardens should be weeded at least 4 times a year, and in special years, it should be more than 6 times. With 3 to 4 laborers, the cost of weeding per mu is as high as more than 1,000 yuan, and the cost of weeding labor in tea gardens accounts for more than 60% of the management costs o...
