【摘要】 探讨不同施用量下黄腐酸生物有机肥与常规施肥对水稻生理性状和产量的影响。结果表明：施用黄腐酸生物有机肥对水稻植株分蘖数、实粒数等具有促进作用和增产效果，以667 m2施用20 kg黄腐酸有机肥所获得的收益较多；此后增加有机肥施用量则水稻增产幅度会下降，种植收益随之降低。更多还原

【Abstract】 This paper discussed the effects of fulvic acid bio-organic fertilizer and conventional fertilization on physiological characters and yield of rice. The results showed that: The application of bio-organic fertilizer of fulvic acid could promote and increase the yield on the tiller number and real grain number of rice plants, and the application of 20 kg fulvic acid organic fertilizer with 667 m2obtained more benefits; After increasing the amount of bio-organic fertilizer, the rice yield would decrease, and the planting income would decrease.更多还原
