摘要
采用田间小区试验考察了有机-无机复混肥对晚稻产量和产量构成因素及土壤养分的影响。结果表明:施用有机-无机复混肥(N-P2O5-K2O为10-4-6),能有效增加晚稻的有效穗和每穗实粒数,显著提高结实率,从而使晚稻增产,该处理比无肥处理增产67.09%,比施单质化肥、无机复混肥处理分别增产18.48%、15.35%;且能使土壤肥力得到有效提升。
The effects of applying organic-inorganic compound fertilizer on yield and yield components of late rice and soil nutrients were researched by field plot experiment.The results showed that applying organic-inorganic compound fertilizer(N: P2O5: K2O= 10: 4: 6) can effectively increase effective panicle and filled grain number per panicle of late rice and significantly enhance seed setting rate of late rice;the yield of late rice reached 5 833 kg/hm2,which respectively increased by 67.09%,18.48% and 15.35% in comparison with non fertilizer,single fertilizer and inorganic compound fertilizer;the soil fertility was improved effectively.
