摘要
田间试验结果表明:麦阔净对麦类田双子叶杂草有良好的防除效果,对作物安全,使用剂量1950g·hm-2;田间双子叶杂草危害严重且有多年生双子叶杂草,进行苗期用药,于麦苗3—4叶1心期,双子叶杂草2—4片(轮)叶期,对水225kg·hm-2均匀喷施,除草效果达90%—95%;田间只有一年生双子叶杂草,且土壤潮湿,可作播后苗前耱(耙)地时施药,除草效果达85%—90%。灭草后增产显著。
The field trials showed that Maikuojing(MKJ) had a good effect to control dicotyledonous weed in wheat field and safe to wheat,The dicotyledonous weed occuring are serious and perennial .MKJ mixed water 225kg·ha^(-1)is sprayed on stem and leaf,it was applied during 3 leaves to 4 leaves and 1 spear leaf of wheat seedings,and 2 leaves to 4 leaves of dicotyledonous weed.The control effect were about 90%—95%.It could be applied it after sowing and before seedling emerged of wheat when there are only annual weeds in wheat field and soil is humid.The control effect were about 85%—90%.Wheat yield will be increased after controlled wheat field weed.
