摘要
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 。
The experimental result indicated that PP 333 can shorten the plant height and raise the yield significantly. The suitable time of the chemical spraying should be among the standing to jointing stage. The optimum spraying concentration was 900 g/hm 2 and 600～750 g/hm 2 PP 333 solved in 750 kg/hm 2 water,respectively,used in standing stage and jointing stage. Also, the different method of using PP 333 in different wheat varieties and the possibility of wheat grain quality improvement by using PP 333 was discussed.
