| 摘 要： | 在小麦返青期和起身期喷施浓度为270~1 080 g/hm2的2,4-D丁酯乳油,研究其对不同小麦品种的影响。结果表明:起身期喷施2,4-D丁酯乳油对小麦农艺性状及产量影响较小;返青期用药对小麦穗粒数影响最大,对穗数和千粒重也有不同程度的影响,小麦产量降低,且减产幅度随着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: | The effects of spraying 2,4-D butylate at returning green stage and standing stage on the growth and yield of wheat were studied.The results showed that spraying at standing stage had little influence on the agrononic characters and yield.Spraying at returning green stage had great influence on the grain number per spike,and had some degree impact on the spike number and 1 000-seed weight.The yield decreased with the increasing of conscentration of 2,4-D butylate.The sensitivity of wheat varieties to 2,4-D butylate in oder was Shixin 733Jifeng 703Ji 5265. |
