目前,国内玉米生产中劳动力成本越来越高,农民往往入不敷出,玉米籽粒直收势在必行。夏玉米,尤其是我国的黄淮海夏玉米区,由于生长期短和地理纬度的因素,难以实现籽粒直收。东单913是专家们针对黄淮海夏玉米区研发的籽粒直收新品种,本片主要从该品种的成熟度、品质和含水量三方面,向观众介绍它适合籽粒直收的原因;并且对它良好的抗倒性、穗轴硬、高产、抗病性好等品种特性也都作了详细的介绍。
At present, the labor cost in domestic corn production is getting higher and higher, and peasants often make ends meet, so it is imperative that corn grain will be levied directly. Summer maize, especially the Huang-Huai-Hai summer maize region in China, is difficult to achieve direct grain harvest due to short growing period and geographical latitude. Dongdan 913 is a new direct-seeded grain variety developed by experts for the Huang-Huai-Hai summer corn area. The film mainly introduces the reasons for its direct grain harvest from the three aspects of maturity, quality and water content of the variety. Good lodging resistance, cob hard, high yield, good disease resistance and other varieties are also introduced in detail.
