| 摘 要： | 研究了单施钾肥及与氮磷配施 ,对转基因抗虫棉的影响。结果表明 ,关中棉区基施钾肥 (单施或与氮磷配施 )可促进抗虫棉早熟 ,增产显著。 10月 10日前收获量提高 15 .5 %～ 32 .3% ,皮棉产量增加 8.4 %～ 19.0 % ;棉铃素质和纤维品质变优 ;各处理中 ,以氮磷钾配施效果最好。在土壤肥力发生变化及当前生产水平下 ,应重视基施钾肥 ,实施“稳氮增磷增钾”平衡施肥策略。

| Abstract: | The studies on effect of potassium fertilizer which was applied singly or together with phosphate and nitrogen on transgenic pest-resistant cotton showed that base K fertilizer applied singly or together with N,P at cotton belt in middle of Shaanxi province could make pest-resistant cotton earlier and increased yield by 15.5%-32.3% in harvest before 10 Oct., 8.4%-19.0% in lint yield,and boll economic characteristic and fibre quality become better,with the best effect in of base K fertilizer combined with N,P fertilizers. According to the soil fertility and productivity level in this region, the base fertilizer, N,P,K should be applied proportionally, namely stabilizing N and increasing P and K. |
