针对山西省中部地区光热资源种植小麦、玉米一熟有余、两熟不足的现状 ,开展了小麦 -玉米一年两熟栽培技术研究。研究结果表明 ,通过选用太原 61 0、长 5 0 2 2、京核941 0、京核 931等早熟、优质、高产的小麦品种和太特早 3号、太特早 4号特早熟以及晋单 32号、晋单 2 2号等中熟玉米品种 ,配之以地膜覆盖、育苗移栽、应用植物生长调节剂等栽培技术 ,可以实现小麦 -玉米一年两熟 ,并获得“亩产吨粮”的效果
Aiming at the current situation that the light and heat resources planting wheat and corn in the central region of Shanxi Province have more than one ripeness and insufficient ripening condition, the research on cultivation technology of double ripening of wheat and corn a year has been carried out. The results showed that the early maturity, high quality and high yielding wheat cultivars such as Taiyuan 61 0, Changbai 502, Jingjing 941 0, Jingkun 931, 32, Jin 2 # 2 and other medium-sized corn varieties, with mulching, transplanting seedlings, the application of plant growth regulators and other cultivation techniques, wheat-corn can be achieved twice a year, and access to “yield per ton of grain ”Effect
