摘　　要：通过2009～2012年4a田间小区试验,研究了紫云英翻压量和化肥施用量对水稻生长、产量及经济效益的影响。结果表明：15 000～22 500 kg/hm^2翻压量的紫云英配施60%～80%常规施肥量时,水稻株高极显著高于对照,也显著高于常规施肥量水稻株高;紫云英翻压对水稻千粒重没有显著影响,它主要是增加了水稻的有效穗数、穗实粒数从而提高水稻产量;22 500 kg/hm^2紫云英配施60%化肥量下的水稻产量最高（2011年除外）;60%化肥量下配施15 000～22 500 kg/hm2紫云英的稻谷净收入比常规施肥高6%～7%。综合考虑,当地水稻施肥采用翻压22 500 kg/hm^2紫云英配合60%常规施肥量比较合适。To investigate the effects of Astragalus sinicus manure （ASM） application and chemical fertilizer （CF） dosage on gTowth, yield and economic efficiency of rice, a field experiment was carried out in 2009 - 2012. The results showed that application of 15 000 -22 500 kg/hm^2 ASM and 60% -80% of locally tradi- tional CF in paddy field significantly gave the higher rice height in comparison with the locally traditional CF as well as the control. ASM application showed no significant effects on the thousand seed weight, however, it might elevated the yield, chiefly ascribed to the increase in the effective panicle number per plant and grain number per panicle. The highest yield of rice was investigated from the treatment applying 22 500 kg/hm^2 ASM combined with 60% locally traditional CF （except for 201 la） , whose the paddy net income was 6% - 7% higher than that with locally traditional CF. Therefore, the combined application of ASM at 22 500 kg/hm^2 with 60% locally traditional CF was suitable in Xinyang District.
