摘　　要： 以水稻品种F-2000为材料,进行了施用不同肥料防治水稻病虫草害、提高产量的技术的研究。在每公顷施氮195 kg、一次性全层施肥的同一条件下,设尿素、氮磷钾复合肥、BB硅肥、生物有机肥、生物有机肥+尿素、畜粪等6种肥料处理,以不施肥为对照。结果表明:与单施无机肥尿素和氮磷钾复合肥相比,BB硅肥、畜粪的处理对水稻主要病虫害稻纵卷叶螟有较好的控制作用,与不施肥无显著差异。与施用生物有机肥、生物有机肥+尿素和对照相比,施用畜粪和氮磷钾复合肥处理的杂草密度显著降低。与对照相比,所有施肥处理产量均有较大提高。 Different fertilizers were applied in the paddy field (variety F-2000) to observe their effect on diseases and insect pests, weeds and paddy yield. The six fertilizer treatments (urea, N-P-K complex, BB-Si fertilizer, organic manure, organic manure + urea, and animal manure) were designed with a control (no fertilizer) and the paddy field was applied with 195 kg pure nitrogen per hectare as basal dressing at one time before transplanting. The results showed that rice leafroller (Cnaphalocrocis medinalis] was better controlled in the treatments of BB-Si fertilizer and animal manure as compared with urea, indicating no remarkable differences from the control. The densities of weeds were remarkably decreased in paddy fields applied with animal manure and N-P-K complex as compared with the organic manure, the organic manure + urea and the control. All fertilizer treatments increased the paddy yield substantially as against the control.
