水稻秧田草害是影响秧苗健壮多蘖的重要原因之一。人工拔草,每亩需7～10个工,使用除草醚等常规药剂除草,由于4月下旬至5月上旬育秧期间气温偏低,故防效较差。为了解决秧田草害问题,我站1983、1984两年进行了丁草胺防除秧田杂草试验,证明丁草胺是一种杀草谱广、药效期长、受低温影响较小、安全、高效的秧田除草剂。 Planting rice seedling is one of the important reasons that affect the sturdy seedlings. Artificial weeding, per acre to be 7 to 10 workers, the use of weed and other conventional herbicides weeding, as late April to early May early low temperature during seedling, it is less effective. In order to solve the problem of grass seedling damage, we carried out the weed control of butachlor in seedling field in 1983 and 1984, and proved that butachlor is a broad-spectrum herbicide with long-term efficacy, less affected by low temperature, safe, Efficient seedling herbicide.
