| 摘 要： | 在日光温室水肥一体化栽培条件下,研究了5个氮肥施用水平对土壤硝酸盐含量、彩椒产量及经济效益的影响。结果表明:不同氮肥施用水平下,0～20cm土壤硝酸盐含量均高于20～100cm土层;随着氮肥施用量的增加,0～20、20～40、40～60、60～80、80～100cm各土层土壤硝酸盐含量及0～100cm土壤硝酸盐累积量均呈升高趋势。15kg·(667m2)-1施氮水平(中等氮肥)下,日光温室彩椒产量、经济效益及其单位氮素增收均为最高。

| Abstract: | The effects of 5 nitrogen levels on soil nitrate contents,color pepper(Capsicum annuum L.)production and economic benefits were studied under the greenhouse cultivation conditions with integration of water and fertilizer.The results showed that the soil nitrate contents in soil layer 0-20 cm were higher than that of soil layer 20-100 cm for different nitrogen levels.Along with the increasing amount of applied nitrogen fertilizer,soil nitrate contents of different soil layers and soil nitrate accumulation at... |
