水稻直播栽培,以其独特的优越性受到广大农户的青睐,应用面积稳中有升。但直播稻苗体小,土壤裸露程度重,加之前期以湿润灌溉为主,十分有利于各类杂草的发生,成为高产、稳产的障碍。目前大面积实际生产中,直播水稻田杂草的化除次数较多,工本较高。故我们从1994年开始,进行了有关旱直播水稻田杂草的一次性化除配方的试验探讨,旨在为大面积直播水稻高效、经济化学除草提供参考。 Rice direct seeding cultivation, with its unique advantages favored by the majority of farmers, the application area steadily. But the direct seeding rice seedling body is small, the degree of soil nuisance is heavy, combined with pre-wet irrigation primarily conducive to the occurrence of various weeds, a high yield, stable yield barriers. At present, a large area of ​​actual production, weeds in direct seeding rice fields in addition to the number of times, the higher the cost. Therefore, we started from 1994 to conduct a trial on the formula of weeds in dry-sowed rice paddy in order to provide a reference for the efficient and economic chemical weeding of large-area direct-seeded rice.
