1．6％胺鲜酯对水稻生长影响及增产作用研究

[目的]研究1．6％胺鲜酯对水稻生长和增产作用。[方法]在田间小区试验条件下，研究试验药剂不同使用剂量对水稻生长、增产效果和田间应用安全性。[结果]1．6％胺鲜酯水剂制剂稀释1000—1500倍，连续用药2次，水稻增产率达6．51％以上，与对照药剂相当，对环境和作物安全。[结论]1．6％胺鲜酯水剂是调节水稻生长性状和增产增效较为理想的药剂。

Effect of Diethyl Aminoethyl Hexanoate 1.6 % AS on Growth Regulation and Yield Increase of Rice

[ Objective ] The aim was to study effect of diethyl aminoethyl hexanoate 1.6% AS on growth regulation anct ylelcl mcrese oI rice. [ Method ] Different doses of the test drug were used to study regulatory role on rice production, yield and field application security. C Result Diethyl aminoethyl hexanoate 1.6% AS was good and a more ideal plant growth regulator with better promotion on rice growth and yield, at dose rate of synergies preparations diluted 1 000 to 1 500 times, the rice yield increase rate was above 6.51% by continuous spraying 2 times in Guangdong, and safety to environment and crop. [ Conclusion] Diethyl aminoethyl hexanoate l. 6% AS was safe and ideal reagent in regula- ting rice growth traits and yield increase.
