Abstract
An experimental study on spring weed control in tea garden was conducted with four control measures [intercropping white clover(Trifolium repens),rice straw mulching,intertilling and weeding,and chemical weed control] from March to June,2013.The results showed that rice straw mulching had a marked control effect on the spring weeds in tea garden,its plant control effect and fresh-weight control effect were above 90%,which were equivalent to those of chemical weed control;rice straw mulching also had obvious control effect on the plant height of main weeds.Intercropping white clover played a certain role in controlling both the quantity and the biomass of main weeds.Chemical weed control had a better control effect on all major weeds,its plant control effect and fresh-weight control effect were more than 90%,and the average plant height of main weeds was only 3.72 cm.The control effect of intertilling and weeding on the main weeds in tea garden was lower than that of rice straw mulching and chemical weed control.
