Description

technical field [0001] The invention relates to the field of controlling weeds in tea gardens, in particular to a method for controlling weeds in tea gardens by covering early straw. Background technique [0002] With the transfer of rural labor force, weeds in tea gardens have been changed from manual weeding to chemical weeding. The use of herbicides has caused some herbicide residues in organic tea to exceed 10 times the European and American standards. Therefore, herbicides are one of the main factors affecting the quality of tea in my country. one. In the past 10 years, rural living standards have gradually improved, and the fuel has been changed from rice straw to gas and electricity. Only a small part of straw is used, and most of it is burned in the field, which not only pollutes the air, but also affects traffic safety. To this end, we carried out research on the control of weeds by early rice grass as a bedding in tea gardens. Contents of the invention [0003]...
