摘要
[目的]选择出能在水稻直播田大面积推广的封闭除草剂。[方法]通过对30%丙.苄DP等4种药剂的不同用量封闭处理水稻直播田防除杂草的效果对比,探讨最佳的除草剂及其用量。[结果]结果表明,参试药剂封闭处理水稻直播田对杂草都有一定的效果,以30%丙.苄、50%惠除一号、35%丙.苄和30%丙草胺4种药剂的效果较为理想,在今后水稻直播田杂草封闭处理的工作当中可以考虑推广使用。[结论]研究结果为稻田除草提供了参考依据。
[Objective] The aim was to select herbicides which could be used for rice direct sowing paddy fields in large scale. [Method]The best herbicide was selected and the best dosage was studied, by comparing the weeds controlling effects of 30% C-Benzyl DP and other three herbicides with different dosages in rice direct sowing paddy field. [Result]The results showed that the tested chemicals had a certain effect on weed in rice direct sowing paddy fields. The effects of 30% C .benzyl, 50% Pendimethalin-Isopropyl ＂Benzyl, 35% C, benzyl and 30% Pretilachlor were better, and which could be considered to promote the use among weed blocking treatment work in rice direct sowing paddy fields in the future. [Conclusion] The research results provided a reference for controlling weeds in rice direct sowing paddy fields.
