| 摘 要： | 利用田间试验,在高、中两种肥力稻田中研究不同配比施肥对晚稻产量、产量构成因素及经济效益的影响。结果表明,与不施氮肥和CK相比,不同配比施肥显著提高晚稻产量,中产田晚稻产量NPKZn处理>-Zn处理>-P处理>-K处理>习惯施肥处理>30%M+70%F处理>CK处理>-N处理,高产田NPKZn处理>-Zn处理>习惯施肥处理>-P处理>-K处理>30%M+70%F处理>-N处理>CK处理;与不施氮肥和CK相比,不同配比施肥有利于提高水稻株高和有效穗,但对结实率和千粒重无明显影响;除不施氮肥处理外,各配比施肥处理净收入均高于不施肥处理;农民习惯施肥处理获得的经济效益较高。 |

| Abstract: | Effects of different amount of combined fertilization on late rice yield,main agronomic characters and economic benefits in late rice were studied by using field experiment under high and medium yield levels.The results showed that the fertilization significantly increased rice grain yield compared with CK and-N treatment.The orders of grain yield from high to low were NPKZn>-Zn>-P>-K>fertilization practice of farmer(FFP)>30%M+70%F>CK>-N under medium fertility field,and NPKZn>-Zn>FFP>-P>-K>30%M+70%F>-N>CK under high fertility field.Fertilization was helpful to improve strain height and effective panicle number except for-N treatment compared with CK treatment.Different combined fertilization had no obvious influence to seed setting rate and 1000-grain weight.Fertilization improved the net imcome compared with CK and-N treatment.The economic benefits of fertilization practice of farmer treatment were higher compared with the other combined fertilization treatments. |
