摘要： 为探索三叶草作为有机栽培中肥料来源,研究间作三叶草对大田甜玉米产量品质,植株全氮和土壤矿质氮的影响,结果表明:与单作相比,甜玉米与三叶草间作可提高甜玉米产量,可溶性糖含量,植株全氮含量,降低了亚硝酸盐含量和土壤中矿质氮含量,但提高了硝态氮含量,降低了Vc含量,在本试验条件下认为,间作三叶草提高甜玉米产量,改善品质,减少化肥的投入,降低环境风险。

关键词: 甜玉米-三叶草间作, 产量品质, 植株全氮, 矿质氮

Abstract: For exploring the organic cultivation of clover as a fertilizer source,effects of intercropping clover on sweet corn yield and quality,plant total N content and soil mineral nitrogen were studied. The results showed that:Compared with monoculture,sweet corn and clover intercropping can improve sweet corn yield,soluble sugar content,plant total N content. Reduce the nitrite content and soil mineral nitrogen content,but increase the nitrogen content,reduce the Vc content,in this experiment,intercropping clover can increase sweet corn yield,improve quality,reduce fertilizer inputs,and reduce environmental risks.

Key words: Sweet corn and clover inter-cropping, Yield and quality, Plant total N, Mineral N
