| 摘 要： | 目的]探讨在安徽省沿江及皖南稻区的双季水稻种植模式下,相同肥料用量紫云英与化肥配施对水稻生长发育及产量的影响。方法]进行早稻施肥效应试验,分析水稻生长发育各期间生理指标、经济性状与不同施肥处理的关系。结果]化肥-紫云英配施的水稻分蘖质量较高、有效穗较多;虽使水稻分蘖期和成熟期推迟,但对农业生产无显著影响;紫云英的肥效相对化肥较慢,第1季对产量的促进并不明显,但在第2季的增产明显。综合各个处理生长发育状况、经济性状和产量,60%化肥＋40%紫云英配施是比较合适的化肥-紫云英配施比例。结论]紫云英在一定程度上可以取代化肥,提供水稻生长发育需要的氮素,并且在比例、用量合理的情况下,第1季总体产量不受显著影响。作为绿肥,紫云英对后续作物及土壤的改善效应有待进一步研究。
