为了在不降低玉米整体种植密度的条件下降低倒伏率和含水量,同时增加玉米产量,研究了玉米田的三空栽培模式技术,即:间隔空垄、割秆空顶、横向空地相结合的栽培模式。研究结果表明:在间隔空垄数:播种垄数=2:12,割秆处理垄数:未割秆处理垄数=2:4,垄长大于1000 m,每隔500 m,田间垂直于垄向空地2 m的三空栽培模式下,玉米倒伏率降低11个百分点,玉米籽粒含水量降低9个百分点,玉米增产20.32%。玉米三空栽培模式能够显著降低玉米倒伏率和籽粒含水量,同时增加玉米产量。玉米三空栽培模式是适宜黑龙江省玉米生产的栽培措施。
In order to reduce the lodging rate and water content without reducing the overall planting density of maize and increase the yield of maize, the three-empty planting mode technique of maize field was studied: the combination of space-covered ridge, Cultivation mode. The results showed that in the interval of the number of empty ridges: sowing ridge number = 2: 12, cutting ridge treatment ridge number: uncut straw ridge = 2: 4, ridge length greater than 1000 m, every 500 m, Under the three-empty cultivation model with open space of 2 m, the lodging rate of maize decreased by 11%, the water content of maize decreased by 9% and that of maize increased by 20.32%. The three-cropping pattern of corn can significantly reduce the lodging rate of maize and water content of grain, and increase the yield of corn. Three cultivation patterns of corn is suitable for the cultivation of corn production in Heilongjiang Province.
