| 摘 要： | 目的]研究植物生长调节剂麦巨金对德抗961小麦产量和株高的影响。方法]以小麦耐盐品种德抗961为材料,在小麦起身拔节期喷施麦巨金,对小麦产量、穗粒数、千粒重、株高、穗长、穗下各个茎节进行调查分析。结果]随着喷施麦巨金次数的增加,穗下各个茎节长度缩短越大,尤其是倒二节间和穗下茎,最终显著降低株高;能够改善小麦的产量构成要素,随着喷施次数的增加对穗粒数和千粒重影响越大,最终小麦产量增幅越大。结论]在小麦起身期间隔14 d连续喷施2次麦巨金效果较好,不仅能够显著降低小麦株高,还能够明显提高穗粒数和千粒重,最终显著提高小麦产量。

| Abstract: | Objective] The objective of this experiment was to study the effect of plant growth regulator,Maijujin,on yield and plant height in wheat cultivar Dekang 961.Method] The research was carried out with salt-tolerant wheat cultivar Dekang 961 by spraying plant growth regulator at standing and jointing stage.The main traits,including yield,grain number per spike,1 000-seed weight,plant height,spike length and stem nodes,were evaluated.Result] Increasing Maijujin application times shortened the length of lower internodes,particularly the top second stem and under-spike internode,lead to significantly reducing in plant height.The Maijujin also improved wheat yield components.With the increase of application times,spike grain number,seed weight and wheat yield increased accordingly.Conclusion] The effect of twice Maijujin spraying at standing stage with an interval of 14 days was the best.It not only significantly reduced the plant height but also improved spike grain number and seed weight,which improved wheat yield in the end. |
