摘要: 通过马铃薯-毛豆-晚稻轮作制2 年定位田间试验,研究不同施肥模式对菜稻轮作产量和菜田氮磷浓度的影响。结果表明:经济施肥使三季作物获得显著增产效果,一个轮作周期下净增收比CK处理增加23.7%,比习惯施肥处理增加10.5%。一个轮作制中,氮磷肥表观利用率分别达到60.5%和16.0%,比习惯施肥提高了15.6 个百分点和7.3 个百分点。马铃薯-毛豆连作在经济施肥下,土柱渗漏水硝态氮和总磷浓度分别比基础土壤提高了63.3%和30.6%,但与晚稻轮作后,土柱渗漏水硝态氮和总磷浓度与基础土壤大致持平。因此,菜稻轮作结合经济施肥是菜田养分管理的有效技术模式。

Abstract: A 2-year stationary field experiment of potato-green soy bean-late rice rotation was carried out to study the effect of different fertilization patterns on the yield of vegetable- rice rotation and nitrogen and phosphorus concentration in vegetable field. The results showed that economic fertilization increased the yields of three crops significantly, the net profit of one rotation cycle increased by 23.7% and 10.5% respectively compared with that of CK treatment and farmer fertilization. The apparent use efficiency of nitrogen and phosphorus was 60.5% and 16.0% respectively, which increased by 15.6 percentage points and 7.3 percentage points respectively compared with that of farmer fertilization under one rotation system. Soil NO3-- N concentration and total P concentration in percolating water of soil-pillar increased by 63.3% and 30.6% respectively compared with that of basal soil in the potato-green soy bean continuous cropping under the mode of economic fertilization. However, soil NO3--N concentration and total P concentration remained stable under the potato-green soy bean-late rice rotation. Therefore, it could be concluded that the modes of the vegetablevegetable-paddy rice rotation with economic fertilization was an effective technical mode for nutrient management in vegetable field.
