自1978年开始,我们在黄麻田对五氯酚钠、除草醚、敌稗、拉索、氟乐灵等除草剂进行了除草效果比较试验。结果证明:氟乐灵是目前麻田较理想的除草剂,杀草率高、对黄麻幼苗安全、植株生长正常、产量稳定、施用方便。1981—1982年我们对氟乐灵的药效作了进一步的试验,现将上述试验简报如下。 (一)材料及方法 1.参试品种;“粤圆5号”。 2.供试药剂:48％氟乐灵乳剂,又名茄科灵(法国产),商品名称Trifluralin,普通名称Trefan。 3.试验处理: (1)药剂用量:每亩用0.12斤、0.16斤、0.20斤、0.24斤等4种处理。
Since 1978, we conducted a comparative herbicidal effect test on herbicides such as sodium pentachlorophenate, weed herbicides, propanil, cable, trifluralin in jute field. The results showed that trifluralin was the ideal herbicide currently in field, with high rate of killing grass, safe for jute seedlings, normal plant growth, stable yield and convenient application. In 1981-1988, we further tested the efficacy of trifluralin. (A) Materials and methods 1. Varieties of the test; “Yue Yuang 5”. 2 for the test agent: 48% trifluralin emulsion, also known as Solanar (France), trade name Trifluralin, common name Trefan. 3. Test Treatment: (1) dosage: 0.12 kg per mu, 0.16 kg, 0.20 kg, 0.24 kg and other four kinds of treatment.
