摘要
以垦鉴豆28为材料,研究同一时期喷施不同剂量多效唑对大豆生长的影响。结果表明:不同剂量多效唑对大豆生育期没有影响,均能够降低植株高度,增加植株茎粗,缩短植株节间长度。其中喷900g·hm-2多效唑处理的产量最高,比对照增产29.53%。
Taking Kenjiandou 28 as test material ,the effect of different paclobutrazol dosages on growth of soybean was studied .The results showed that different dosages of paclobutrazol had no effect on soybean growth period ,all treatments could decreased plant height ,increased stem diameter ,shorten internode length .The yield of treatment 3 was the highest ,increased by 29 .53% than CK .The suitable dosages of paclobutrazol was 900 g·hm^‐2 .
