稻田杂草丛生,争夺水稻的阳光、水分和养料,严重影响产量,稻田杂草的防除是水稻栽培中一个很重要的问题。直至目前为止,我国广大农村仍然采用人工除草或部分地区采用机械除草来防除田间杂草。随着祖国农业现代化的不断发展,在不久将来,现代化省力的化学除草将会逐渐推广。
The weeds are overgrown in the paddy fields, scrambled for sunshine, moisture and nutrients in the rice so as to seriously affect the yield. The prevention and control of paddy weeds is a very important issue in rice cultivation. Until now, the majority of rural China still use artificial weeding or mechanical weeding in some areas to control field weeds. With the continuous development of agricultural modernization in the motherland, the modernization and labor-saving chemical weeding will be gradually promoted in the near future.
