为进一步明确多效唑(MET)作为防倒剂在小麦上应用的适宜时期和用量以及增产效果,1987～1989年,笔者先后于不同时期、不同施肥量下进行了MET用量试验,为小麦高产栽培肥促化控提供依据。 方法与经过 试验Ⅰ:以施药时期、施药量(MET有效成份,下同)为试验因子,采用最优回归设计。
In order to further clarify the appropriate period and dosage of MET as a down-pouring-inhibiting agent in wheat and its yield increasing effect, from 1987 to 1989, the author conducted MET dosage tests at different periods and different fertilizers, Promote the chemical control basis. Methods and after the test I: the application period, the dose (MET active ingredients, the same below) as a test factor, using the optimal regression design.
