经近年试验、示范及大田调查,地膜玉米套种地膜洋芋是我县一种较为理想的“双千田”栽培模式。它集高秆——低秆、喜光——耐阴、耗地力大——耗地力小于一体,通过立体种植、增加叶面积覆盖率及边行优势等途径,显著地提高了单位面积产量和经济效益。97年我县已示范种植10km~2。现将栽培技术要点简介如下: After years of experiments, demonstrations and field surveys, mulching film mulching with potato starch is an ideal “double-thousand” cultivation model in our county. It combines high stalk - low stalk, hi light - shade, consumption of large force - consumption of less than one force, through the three-dimensional planting, increased leaf area coverage and advantages such as side lines, significantly increased yield per unit area and economy benefit. In 1997, my county has demonstrated planting 10km ~ 2. The cultivation techniques are summarized as follows:
