水稻等蘖穗定向栽培技术研究

A Study on the Directional Cultivation Techniques of One Tiller One Panicle in Rice

通过多项试验，探讨赤霉素、施用穗肥在水稻等蘖穗定向栽培技术中的作用，初步明确了赤霉素施用时期与浓度，以及搁田和施肥与赤霉素联因的较佳时期，为水稻等蘖穗定向栽培提供配套技术。

This paper dealt with the effects of spraying GA 3 and applying fertilizer at spike differentiation stage on the formation of productive panicle in rice cultivation of “One Tiller One Panicle” through several trials. The established time and concentration of spraying GA 3,the optimum drainage time and fertilizing method would provide a set of techniques for directional culture of one tiller one panicle in rice cultivation.
