摘　　要：2013年3～6月开展了间种白三叶草（ Trifolium repens）、稻草覆盖、中耕除草和化学除草4种措施控制茶园春季杂草的试验研究。结果表明：稻草覆盖对茶园春季杂草的控制效果明显，其株防效和鲜重防效达90％以上，与化学除草结果相当，对茶园主要杂草的株高也有显著的控制作用；间种三叶草处理措施对茶园主要杂草数量、生物量均有一定的控制作用；化学除草对茶园各种主要杂草均有较好的控制效果，其株防效和鲜重防效达90％以上，主要杂草平均株高仅为3．72 cm；中耕除草对茶园主要杂草防效不及稻草覆盖和化学除草。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 mulc-hing 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 .
