摘要
为筛选出对糜子安全、高效的苗后茎叶处理除草剂,以齐黍2号为试验材料,研究不同除草剂对糜子田间主要杂草的防除效果。结果表明:在糜子4~5叶期,选用38%莠去津、57%2,4-D丁酯、48%灭草松,在剂量分别是5250,1300,3400 g·hm-2时防除糜子田杂草效果最佳,株防效都达到80%以上;与清水对照相比,38%莠去津的增产效果最佳,增产率达到了44.8%,48%灭草松增产次之。
In order to screen out a safe and efficient herbicide for the treatment of post seedling stem and leaf of millet,the effects of different herbicides on the main weeds in the field of millet were studied with Qishu No.2 as the experimental material.The results showed that 38%atrazine,57%2,4-D butyl EC,48%bentazone were the best for controlling the weed during 4-5 leaf stage,3 kinds of herbicides in dose were 5250 g·hm-2,1300 g·hm-2,3400 g·hm-2 respectively,strain control effect of broomcorn millet field weeds was 80%or more;Compared with spraying water contrast,yield-increasing effect was best by spray 38%atrazine with increase rate of 44.8%,following 48%bentazone.
