爱辉区地处我国北部高纬寒地,无霜期短,有效积温少,热量不足。为促进玉米早熟高产,我们在良种选用、土壤耕作和田间管理等方面进行探索与研究,总结出适合本地区高产实用栽培技术,并广泛推广应用。 Aihui District is located in northern China high latitude cold, frost-free period is short, less effective accumulated temperature, lack of heat. In order to promote early maturity and high yield of maize, we explored and researched the selection of elite seeds, soil cultivation and field management, and concluded that the high-yield and practical cultivation techniques suitable for this area were widely popularized and applied.
