| 摘 要： | 以桂糖29号、桂糖02 -1156、桂糖05 -3084、新台糖22号4个甘蔗品种为材料,用56％二甲四氯钠盐、48％蔗草灭、38％莠去津、99.9％乙草胺4种除草剂做防除杂草的田间试验.结果表明:甘蔗产量最高的为38％莠去津胶悬剂处理,但各处理间差异不显著；产量构成因素中,茎径差异显著,株高、有效茎数、分蘖率差异不显著.这4种除草剂对甘蔗安全性好,可做土壤封闭和芽后(3～5叶)处理.其中56％二甲四氯钠粉剂对单子叶杂草防效差,99.9％乙草胺乳油对3叶以上的杂草防效差,38％莠去津胶悬剂防效最佳,田间剂量以3 748 g/hm2为宜.

| Abstract: | Field experiment on effect of four kinds of herbicides,56% MCPA sodium,48% Zhecaomie,38% atrazine and 99.9% acetochlor on weed control was carried out with 4 sugarcane varieties,Guitang No.29,Guitang 02-1156,Guitang 05-3084 and ROC22,as materials,and the results showed that yield of treatment of suspension concentrate of 38% atrazine was highest while there was no obvious difference among different treatments.Stalk diameter had significant difference while plant height,millable stalks or tillering rate had not.The four kinds of herbicides were safe to sugarcane,which could be used for soil sprayed and post-emergence(3～5 leaves).Control effect of powder concentrate of 56% MCPA sodium on monocotyledon weeds and that of emulsifiable concentrate of 99.9% acetochlor on weeds with more than 3 leaves was bad.Control effect of suspension concentrate of 38% atrazine was best and the optimal dose was 3 748 g/hm2. |
