研究结果表明 ,多效唑对超高产小麦降秆增产效果较为理想。喷施时期宜在小麦起身期和拔节期。起身期喷施最佳用量为多效唑 90 0g/hm2 对水 75 0kg/hm2 ,拔节期喷施最佳用量为多效唑 6 0 0～ 75 0g/hm2 对水 75 0kg/hm2 。笔者还针对不同类型小麦品种提出了多效唑的不同喷施时期。研究还发现 ,多效唑能有效地改善小麦籽粒品质
The results show that paclobutrazol on super high yielding wheat stalk yield increase effect is more ideal. Spraying period should be in wheat and jointing stage. The optimum amount of application of spraying PP was 90 0g / hm2 on water 75 0kg / hm2. The optimum dosage of PP333 at jointing stage was 60 0kg / hm2. The author also proposed for different types of wheat different paclobutrazol spraying period. The study also found that paclobutrazol can effectively improve wheat grain quality
