于 1 999年 7～ 9月在呼和浩特市清水河县进行了羊柴花期喷施激素和营养素的正交试验 ,结果表明 ,在盛花期喷施激素和营养素类药物时 ,激素类药物比营养素类增产效果好。本试验结果用药浓度选择是种子增产的首要因素 ,而用药种类是地上生物量增产的首要因素。本试验中天丰素在 40 0ml/hm2 下对种子增产效果好 ;喷长精对地上生物量增产效果好。
From January to September 1999, an orthogonal experiment was conducted in Qingshuihe County of Hohhot to spray hormones and nutrients at the bloom stage. The results showed that hormones were more effective than nutrients at the full bloom stage when spraying hormones and nutrients Good yield. The results of the test drug concentration selection is the primary factor of seed production, and the type of medication is the primary factor of aboveground biomass production. In this experiment, cefoonin at 40 0ml / hm2 on the seed yield good effect; Spraying fine on the aboveground biomass yield is good.
