以不同生育期的优质高产小麦、玉米品种做为试验材料,在京郊可利用的光热资源条件下,筛选不同成熟期的小麦-玉米最佳配套组合,为增加小麦、玉米2茬平播产量提供理论依据。试验结果表明:早熟型小麦京冬11与中晚熟型玉米京玉11、中熟型小麦京9428与中熟型玉米京科25、晚熟型小麦轮选987与早熟型玉米宽城1号品种搭配,生育期适应京郊光热资源,产量效益均表现最佳。
Taking the high-yielding wheat and maize varieties with different growth periods as the experimental materials, the best combination of wheat-maize at different maturity stages was screened under the available light and heat resources in the suburbs of Beijing for the purpose of increasing the yield of wheat and maize Production provides a theoretical basis. The results showed that: early maturing wheat Jingdong 11 with late-maturing corn Jingyu 11, medium maturing wheat Jing 9428 and medium maturing Jingke 25, late maturing wheat rotation 987 and early maturing corn Kuancheng 1 , Growth period to adapt to the Beijing suburbs of light resources, yield and performance are the best.
