膜侧小麦应用壮丰安的调控效果研究

根据生育特点、器官建成和产量形成的规律 ,就膜侧小麦应用壮丰安的调控效果进行了试验研究。结果表明 ,壮丰安拌种能有效控制苗期叶片生长 ,明显促进分蘖的形成和根系的发育 ,有利于增强植株抗旱、耐寒性能 ,提高越冬保苗率 ;返青期喷施能显著抑制基部节间的伸长。壮丰安处理一般会引起小麦粒重的下降 ,拌种处理还会导致成穗数减少 ,但穗粒数的显著增加可有效平衡二者下降对产量的影响。膜侧小麦用适宜剂量的壮丰安拌种和喷施 ,一般增产 10 %～ 15 %。与常规露地小麦相比 ,膜侧小麦更适宜于应用化控制剂进行调控。

Regulation Effect of Zhuangfengan for Wheat Grown on Sides of Film in Furrow Line

The experiment was conducted in application Zhuangfengan for regulation of wheat grown in furrow line at different stages, according to the growth characteristics, organ establishment and yield components. The results showed that the seed dressing agent Zhuangfengan could control the growth of leaf at seeding stage effectively and improve the formation of tillers and development of root system. It also improved resistantce to drought and cold damage and increased the rate of seedling survived over wintering. It also inhibited the elongatation of internodes at base remarkably. The treatment of Zhuangfengan often resulted in reduction of grain weight and numbers of formed ear, however, the obvious increase of numbers of grain per ear could effectively balance the effect caused by the former mentioned. For wheat grown on sides of film in furrow line, seed dressing with proper amount of Zhuangfengan and spray usually increased the yield by 10%~15%.Compared with conventional uncovered cultivation of wheat, it was more suitable to regulate the cultivation of wheat on sides of film in furrow line by chemical regulators.
