80年代以来,随着省工简化农艺措施的推广,稻茬免耕移栽油菜面积迅速扩大,而草害问题也日益突出。自1983年起,我们针对生产上出现的这一实际问题,开展了稻茬免耕移栽油菜田的化学除草技术研究,1985年已大面积推广应用,1987年推广应用面积7.8万亩,占油菜种植面积的70.9％。 (一)绿麦隆防除油菜田杂草的优点 1.货源充足,成本较低。绿麦隆是国产农药,货源充足。而稳杀得等进口农药,供货数
Since the 1980s, with the promotion of simplified agronomic measures for migrant workers, the area of no-tillage transplanting rapeseed in rice fields has rapidly expanded, and the problem of grass-pests and diseases has become increasingly prominent. Since 1983, we conducted a study on the chemical weeding technology for no-tillage and transplanting rape field of rice stubble in view of the actual problems in production. In 1985, we have popularized and applied it in a large area. In 1987, the area of 78,000 mu 70.9% of rapeseed area.
