Cultivation Experiment on Interplanting Mode of Alpine White Radish and Sweet Corn with Plastic Film Mulching

为改善长阳高山白萝卜种植效益不高、连作障碍严重等问题,在长阳1 000、1 200、1 400、1 600 m 4个海拔点进行高山白萝卜—甜玉米地膜覆盖试验。试验结果表明,海拔1 200 m的综合产值最高,达4 913.6元/667 m^2,其次是海拔1 400 m,达到4 885.6元/667 m^2。

To improving the low planting benefit, successive cropping obstacles and the other problems of Changyang alpine white radish, cultivation experiment on interplanting mode of alpine white radish and sweet corn with plastic film mulching was carried out in 1 000, 1 200, 1 400 and 1 600 m areas above sea level. The result showed that the comprehensive production value in 1 200 m area above sea level was highest, reaching 4 913.6 yuan/667 m^2.
