小麦穗发芽抑制剂及最佳施药期的研究初报

The Premilinary Report of Preharvest Sprouting Inhibiting Agent and It's Best Spraying Period

本研究基于多年来国内外有关穗发芽发生生理机理的研究成果 ,经室内和田间试验 ,研制筛选出可防止穗发芽的抑制剂 N5 ,N5 的最佳施药期是花后 3 6d左右。该药剂可有效地抑制穗发芽 ,并兼治几种小麦病害 ,成本低 ,无残留 。

Based on the results of many years research of preharvest sprouting physiological mechanism both at laboratory and field, a preharvest sprouting inhibiting agent(N 5) was invented. It was found that the best spraying period was 36 days after flowering. With a low cost and nonharmful remainder and easy application, the agent could effectively control the occurence of preharvest sprouting and could control several wheat diseases.
