秋玉米栽培是实现多元化熟制重要途径。生育特点为营养体小,单株生产力较低,生育期比春玉米短20d,比夏玉米短7d。但前期生长发育快,抽雄后灌浆成熟慢,呈“慢—快—慢”速率变化。要获得秋玉米优质高产,栽培选用早中熟紧凑型抗病良种,7月15日前播种,确保9月10日前抽雄,收获密度5000株/667m~2,采用“促—促—促”施肥,及时防治病虫草害,推迟带秆收获。
Autumn corn cultivation is an important way to achieve diversified cooked. Reproductive characteristics of small nutrients, lower productivity per plant, growth period shorter than spring maize 20d, shorter than summer maize 7d. However, rapid growth and development in the early stage, tasseled filling slow maturity, was “slow - fast - slow” rate changes. In order to obtain high quality and high yielding autumn maize, early maturing and medium resistant varieties should be planted and sown before July 15th to ensure that the density will be 5000 / 667m 2 before September 10, Fertilization, timely prevention and control of pests and diseases, delayed stalk harvest.
