| 摘 要： | 通过大田试验,研究了水稻在不同施肥条件下的经济性状、产量和产值,旨在探索出水稻最佳施肥方案。结果表明:水稻最佳施肥处理为测土配方施肥处理,其经济性状、产量和产值均优于其他处理。具体表现为测土配方施肥处理条件下,水稻单产较习惯施肥处理增加9.5%,增值1 609.2元/hm2,投入少210元/hm2,净收入多1 819.2元/hm2。该区域内水稻生产最佳肥料配方为尿素315 kg/hm2、普钙750 kg/hm2、氯化钾180 kg/hm2,同时应结合施用有机肥。

| Abstract: | The effects of different fertilization models on the economic traits,yield and production value of rice were studied by field experiment to explore the optimum fertilization scheme.The results showed that the formula fertilization by soil testing was the best,with which the yield,production value and net income increased by 9.5%,1 609.2 yuan/hm2 and 1 819.2 yuan/hm2,respectively,and the input reduced by 210 yuan/hm2.The optimum fertilizer formula was urea 315 kg/hm2,calcium superphosphate 750 kg/hm2 and potassium chloride 180 kg/hm2 combining with organic fertilizer. |
