摘要: 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。研究结果明确了玉米三空栽培模式:①间隔空垄数:播种垄数=2:12;②割秆处理垄数:未割秆处理垄数=2:4;③当垄长大于1000 m时,每隔500 m,田间垂直于垄向空地2 m。该三空栽培模式下,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。

Abstract: To reduce lodging rate and moisture without reducing density, and increase the yield of maize, maize three-space cultivation pattern is studied. Maize three-space cultivation pattern is the integration of space in ridges, space in the top of the maize field by cutting off stalk above the corn ear and space crosswise the field perpendicular to ridge direction. The results indicated that the three- space cultivation pattern included, the number of ridges without culture: the number of ridges with culture =2:12, the number of ridges with cutting stalk: the number of ridges without cutting stalk =2:4, the length of space crosswise the field vertically was 2 m per 500 m when the length of ridges was greater than 1000 m. With the above cultivation pattern, the lodging rate of maize was reduced by 11%, grain moisture was reduced by 9%, and the yield of maize was increased by 20.32%. Maize three-space cultivation pattern could significantly reduce the lodging rate and grain moisture of maize, and increase the yield of maize. Maize three-space cultivation pattern is suitable for maize production in Heilongjiang Province.
