水直播稻是水稻高产、省工、经济栽培的新途径。对水直播稻田草害的防除要采取包括农艺措施在内的综合防治,才能取得较好的效果,但化学防除是控制草害的重要手段,在综合防治中起着重要的作用。为此我们在省植保站的部署和指导下,1986年进行了水直播稻田出草规律的系统观察和化学防除试验。
Direct seeding of rice is a new way for high-yield, labor-saving and economic cultivation of rice. The prevention and control of grassland damage to water direct-seeded rice should adopt comprehensive prevention and control measures including agronomic measures to achieve good results. However, chemical prevention and control is an important measure to control grass-roots damage and plays an important role in comprehensive prevention and control. To this end, we plant and plant protection stations in the province’s deployment and guidance, conducted in 1986, the direct observation of the law of rice field drafting rules and chemical control test.
