为探究不同施肥措施对晚稻产量和杂草群落的影响,以1982年布置的双季稻红壤稻田长期施肥定位试验为对象,于2011年采用田间调查法研究了在以无机肥(化肥NPK)与有机肥(M)氮磷钾养分等量条件下,长期施用有机肥、无机化肥和有机无机肥配施模式下晚稻生长发育、晚稻产量及稻田杂草群落变化。结果表明,施肥能促进晚稻生长发育,显著提高晚稻产量,配施效果优于单施,以有机无机均衡配施(NPKM)效果最佳,且其晚稻产量平均高出其他配施处理17. 6%;在施用有机肥的基础上,要使红壤稻田晚稻增产,需优先考虑施用氮肥,其次依次是磷肥和钾肥。施肥处理中,单施化肥最能促进晚稻杂草生物量增加,且其杂草生物量平均高...

To detect the influence of the yield of late rice and the community of weed by different long-term fertilization, we investigated the production and the growth of late rice,the variation of weed community in rice field with the longterm fertilization treatments of control (CK) ,organic fertilizer (M) ,chemical fertilizer (NPK) and combined organicchemical fertilizers (NPKM) under the same condition of nitrogen,phosphorus and potassium in the year of 2011,based on a long-term fertilization experiment of double cropping rice in red soil set in 1982. The results showed as follows. Fertilization p...
