麦套稻田杂草种类多、密度高、出草早、出草期长、危害重。用“一封、二杀、三挑”的防除方法 ,即水稻套种后第 5d用 5 0 %速除 10 0g/6 6 7m2 等除草剂进行土壤封闭。水稻 3～ 4叶期用 36 %二氯·苄 5 0g/6 6 7m2 喷雾进行二杀。水稻生长中后期视田间残留杂草情况 ,用千金等除草剂进行挑治 (三挑 ) ,对水稻安全 ,增产效果好。
Wheat paddy weed species, high density, early grass, a long grass, endanger heavy. With “one, two kill, three pick” method of prevention and control, that is, 5d after rice intercropping 5 0% speed except 100g / 6 6m2 and other herbicides closed soil. Rice 3 to 4 leaf stage with 36% dichlorobenzyl 50g / 6 6m 2 spray kill. In the late rice growing field depending on the situation of weeds in the field, with daughter and other herbicides pick (three pick), rice safety, yield a good effect.
