南方直播水稻浅沟渗灌节水增产机理研究
Because of no differences with weeds in time and location, direct sowing rice with labor saving, low investment and high yield potential also has some shortages in competition for space, so the harm degree of weeds is increased, such as moleplant seed which is unsusceptible to normal weed killers and becomes a severe weed.
直播水稻具有省工、节本、产量潜力高等优点 ,直播稻苗与杂草无时差、位差 ,不存在“空间”竞争优势 ,增加了杂草的危害程度 ,尤其是千金子 ,对目前稻田常用除草剂不敏感 ,已逐渐成为直播水稻田间的恶性杂草 ,部分地块甚至因其猖獗危害而绝收。
