| 摘 要： | 在小麦拔节期喷施浓度为270～1080g／hm^2的2，4-D丁酯乳油，研究其对3个小麦品种株高及农艺性状的影响。结果表明：2，4-D丁酯乳油对不同小麦品种的株高无显著影响，对穗数和千粒重影响不大，小麦穗粒数减少，产量降低，且减产幅度随用药剂量的增加而增大。小麦品种对2，4-D丁酯的敏感性顺序为石新733〉冀丰703〉冀5265。

| Abstract: | Effects of 2,4-D butylate sprayed at the jointing stage on agronomic characters of three wheat varieties were studied.The results showed that 2,4-D butylate had no significant effect on the plant height,and had little effect on the spike number and 1 000-grain weight.The grain number per spike reduced.The yield decreased,and the decreasing range became larger with the increase of the dosage of 2,4-D.The sensibility to 2,4-D butylate of wheat varieties was that Shixin 733>Jifeng 703>Ji 5265. |
