鄂西山区不同海拔与播期对甜玉米生长的影响

Effects of Different Altitude and Sowing Date on the Growth of Sweet Corn in the Mountain Area of Huibei Province

为研究鄂西山区不同海拔高度与播期对甜玉米鄂甜玉4号生长的影响,摸索高山甜玉米种植制度,2012～2013年在湖北省宜昌市长阳县高山蔬菜基地5个不同海拔梯度点安排了鄂甜玉4号分期播种试验。结果表明,鄂西山区鄂甜玉4号种植适宜海拔为1 200 m,适合的播期为4～5月,宜采用不同海拔梯度排开播种技术。

In order to study the effects of different altitude and sowing date on the growth of sweet corn in the west mountain area of Huibei province, and to explore the rule of alpine farming system for sweet corn, sowing experiments of sweet corn on five point of the high mountain vegetable base in Changyang County Yichang city were carried out in 2012 ～2013 year. Results showed that suitable altitude was 1 200 meters. Suitable sowing date was in April to June. For planting sweet corn in the mountain area, different elevation gradient line seeding should be adopted.
