绿色植物生长调节剂GGR6号和GGR8号对冬小麦生长发育及产量的影响

Effects of Plant Growth Regulators GGR6 and GGR8 on Development and Yield of Winter Wheat

[目的]筛选适宜冬小麦的生长调节剂,探讨其适宜的浓度和施用方法。[方法]以邯生329为试验材料,分别采用不同浓度的新型绿色植物生长调节剂GGR6号和GGR8号对河北地区冬小麦进行试验,分析其对冬小麦生长发育及产量的影响。[结果]2种生长调节剂均能促进根茎的发育、干物质的积累、产量性状的改善及产量的增加,尤其以GGR8号20 mg/kg拌种+拔节期20 mg/kg喷施对冬小麦促进效果最好。[结论]该研究可为冬小麦生产中应用植物生长调节剂提供参考。

[ Objective ] The suitable plant growth regulators were screened for winter wheat. Suitable concentration and application method were studied. [ Method ] Taking Hansheng 329 as test material, the effects of different concentrations of new plant growth regulators GGR6 and GGR8 on development and yield of winter wheat in Hebei Province were studied. [Result]The two growth regulators could promote the development of rhizome, the accumulation of dry matter, the improvement of yield characters and the increase of yield. The best treatment for winter wheat was the application of GGR8 20mg/kg seed dressing ＋ 20mg/kg spraying at jointing stage. [ Conclusion ] The research could provide reference for application of plant growth regulators on winter wheat.
