| Abstract: | Effects of different fertilizer modes on the yield and ecological benefits of rice were discussed in this paper.The results showed that :for early season rice,the treament obtained the best yield 8 660 kg/hm2 and ecological benefits 15 647.4 yuan/hm2,that was all phosphate fertilizer+65% nitrogenous and potassic fertilizer as basal fertilizer,35% nitrogenous and potassic fertilizer as panicle fertilizer.For late rice,the treament obtained the best yield 8 780 kg/hm2 and ecological benefits 15 887.4 yuan/hm2,that was all phosphate fertilizer+60% nitrogenous and potassic fertilizer as basal fertilize,25% nitrogenous and potassic fertilizer as tillering fertilizer,15% nitrogenous and potassic fertilizer as panicle fertilizer. |
