化学除草的增产效果草荒是影响直播水稻高产的重要原因和发展水稻直播栽培的主要障碍。经过几年的试验和生产实践,我场从1973年开始实现了直播稻田除草化学化,完全免除了人力和畜力中耕除草。同时,在稻田基本无草的基础上,改宽行大垅为20+5厘米的小垅条播,促进了直播水稻高产。

The effect of chemical weeding on grass yield is a major reason that affects the high yield of direct seeding rice and the main obstacle to the development of direct seeding rice. After several years of experiments and production practices, we started to realize the weed-chemicalization of direct-seeded rice fields in 1973, completely eliminating the manpower and animal-power cultivation and weeding. At the same time, on the basis of basically grass-free paddy fields, the widening of the large rachis to 20 + 5 cm of small raccoon sowing, to promote the direct seeding rice yield.
