一、玉米与贝母套种本模式是根据贝母只在早春生长，夏季需要遮荫休眠的特性，利用二者仅1个月的共生期．家现高产增效的目的。特点是，合理利用了光热资源，在保证单位面积玉米产量的同时，增加了经济效益。l．选地。选择湿润的砂壤土，忌土质粘重的涝洼地。2．栽培方法。做床
First, corn and fritillary intercropping This model is based on Fritillaria only grow in early spring, the need to shade the summer dormancy, the use of both symbiotic period of only 1 month. Home is the purpose of high yield and efficiency. The feature is that the rational use of light and heat resources, while ensuring yield per unit area of corn, increased economic efficiency. l. Choose. Choose moist sandy loam, avoid sticky soil waterlogging depression. 2. Cultivation methods. Make bed
