- 摘要:
- 为探索玉黄金在玉米生长中最佳的使用时间，以绥玉7号为试材，研究了玉米化控剂玉黄金对玉米形态指标、干物质积累及产量的影响。结果表明：8叶期喷施玉黄金能够显著抑制玉米生育前期株高，10叶期喷施玉黄金能显著降低株高、穗位高、增加茎粗；玉米10叶期期喷施适量玉黄金会降低茎叶干物质积累，而喷施过量的玉黄金，导致单穗粒重也降低，进而会降低产量。
- Abstract:
- In order to explore the best use time of chemical control agent Yuhuangjin in maize growth period,taking Suiyu 7 as test material,the effect of chemical control agent Yuhuangjin on morphological indexes,dry matter accumulation and yield of maize was researched.The results showed that the treatment of spray Yuhuangjin at 8 leaves stage could significantly inhibit early stage plant height of maize,the treatment of spray Yuhuangjin at 10 leaves stage could significantly reduce the plant height and ear position high,increased the stem diameter; spray moderate Yuhuangjin at 10 leaves stage could reduce the matter accumulation of stem and leaves,excess Yuhuangjin could decrease grain weight per ear and reduce yield.
