为了推广果园化学除草技术,近年来我们对草甘磷、阿特拉津、拿、净、西草净、禾大壮五种化学除草剂进行了不同浓度的除草试验。喷药时期为5月末至6月初,防治对象有荠菜、小黎、鹅观草、大蓼、马唐、刺儿菜、蒿类、三角菜等杂草。试验结果表明,适于果园除草的药剂为草甘磷和阿特拉津,使用浓度草甘磷以100倍为宜,亩用药量0.5公斤,阿特拉津以300倍为宜,亩用药量0.165公斤。两种除草剂 In order to promote orchard chemical weeding technology, in recent years we glyphosate, atrazine, take, net, sisal net, Wo Dazhuang five kinds of chemical herbicides were weeding at different concentrations. Spraying period for the end of May to early June, prevention objects are shepherd’s purse, Little Li, Goose grass, Polygonum, Crabgrass, Calyxe, Artemisia, triangular vegetables and other weeds. The results showed that the herbicides suitable for orchard weed glyphosate and atrazine, the use of glyphosate to 100 times the appropriate amount of 0.5 kg mu, atrazine 300 times is appropriate, the mu dose 0.165 kg. Two herbicides
