科素1号在寒地水稻上的应用效果

Application Effect of Kesu No.1 on Rice in Cold Region

为探讨叶面营养液在水稻上的应用效果,以水稻品种空育131为试材,科素1号叶面喷施营养液设150、225mL.hm-2和空白对照,采取随机区组设计方法,研究了科素1号叶面营养液对水稻生育的影响。结果表明:喷施科素1号叶面营养液适宜剂量150mL.hm-2的处理抽穗期比对照提前2d,产量比对照增加375kg.hm-2,增产率为3.7%,而喷施225mL.hm-2的处理比对照抽穗期晚1d,产量却比对照低,但在品质上各处理间差异不明显。科素1号叶面营养液在水稻上最佳施用时期为9.5叶期和孕穗期,适宜喷施剂量为150mL.hm-2。

In order to investigate the application effect of foliar nutrient solution on rice,rice variety Kongyu 131 was taken as tested material, the effect of Kesu No. 1 foliar nutrient solution on rice growth was studied by random block design method. The results showed that：when spraying Kesu No. 1 foliar nutrient solution 150 mL. hm-2 , the rice heading stage was two days earlier than the control, the yield was 375 kg. hm2 more than the control, the increase rate upto 3.7% ;When spraying Kesu No. 1 foliar nutrient solution 225 mL.hm-2 ,the rice heading stage was one day later than the control,and the yield was lower than the control, but there was no differences on quality among treatments. The best application period Kesu No. 1 foliar nutrient solution was at 9. 5 leaf stage and booting stage, the suitable spraying dosage was 150 mL-hm-2.
