摘要
本研究结果表明：水稻施用3750mL/hm^2土壤磷活化剂拌种和底施225kg/hm^2化学钾肥氯化钾效果相同,均能增加棉花的有效穗、穗粒数和功能叶叶面积,并提高产量,与常规施肥相比,土壤磷活化荆拌种棉花有效穗数增加21．3万/hm^2,氯化钾处理有效穗数增加22．95万/hm^2；穗粒数分别增加10．90粒和8．77粒；功能叶叶面积分别增加50．37cm^2和27．97cm^2；产量提高20．1%和22%,经方差分析,增产效果达极显著差异水平。
Results of the study indicated that applying 3750ml/hm^2 activation inoculant of soil phosphous to rice could increase the effective ears, kernel numbers per ear, functional leaves area and yield as the same as 225kg/ hm^2 KCl applied as base fertilizer. Compared with usual applying fertilizer, applying 3750ml/hm^2 activation inoculant of soil phosphous and 225kg/ hm^2 KCl achieved the best effect. The effective ears increased 21300ear/hm^2 and 22950ear/hm^2 respectively; kernel numbers per ear increased 10.90 and 8.77 respectively; functional leaves area increased 50.37cm^2 and 27.97cm^2 respectively; yield increased 20. 1% and 22% respectively. Yield of two treatment increase significantly than usual applying fertilizer.
