摘 要: | 试验结果表明,施用生物有机肥及配施氮素化肥比常规施肥均能增产。其中早稻增产12.1%-20.5%,晚稻增产7.5%-17.9%;生物有机肥配施一定量氮素化肥均比单施生物有机肥的增产,其中早稻667m^2增3.9-32.7kg,增1.0%~8.4%。晚稻667m^2增20.1-42kg,增产4.6%~9.7%;生物有机肥配施氮素化肥,以667m^2施绿源生物有机肥70kg加尿素4.3kg为好。建议为达到增产增收,在施用时以667m^2施用60kg生物有机肥,配施5-8kg尿素及5kg氯化钾为好。

Abstract: | The experimental results show that the bioorganic manure's application can increase yield comparing with normal fertilization, thereinto, the increase for earlyr rice is 12.1%-20.5% and 7.5%- 17.9% for late rice. The application of compound fertilizer can increase yield comparing with only bioorganic manure,thereinto, + 3.9-32.Tkg/667m^2 (1.0%-8.4%) for early rice and + 20.1 -42kg/667m^2 (4.6%-9.7%) for late rice. The suggested application is bioorganic manure 70kg/667m^2+ Urea 4.3kg. For best income and yield increase, anonther suggestion application is bioorganic manure 60kg + Urea 5-8kg + Potassium chloride 5kg. |
