四川省盐边县北部地区的光热资源丰富，年温差较小，日温差较大，适合玉米的生长季节长，尤其是灌浆成熟期较长，沿湖（二滩库区）的河谷地带土壤肥沃、水利条件好。例如永兴镇沿湖河谷一带，属于亚热带干热河谷气候区，年日照＞3000 h，年降雨量为1100 mm，年平均气温19～23℃，无霜期约310 d，非常适合种植玉米。为了使玉米创收，提高上市价格，许多农户都选择种植早春玉米。但由于技术和管理不到位，出现了早春玉米受冷害、结穗不佳等现象。对此问题进行了探讨，并提出相应的解决办法，以期能为种植活动提供经验和借鉴。

Abundant light and heat resources in the northern part of Sichuan Province, Yanbian County, the annual temperature difference is small, a large diurnal temperature range, long growing season for corn, especially in the longer filling stage, the lake (Ertan Reservoir) valley Strip fertile soil, good water conditions. For example Yongxing Town lake valley area, a subtropical dry and hot valley climate, sunshine>3 000 h, annual rainfall is 1 100 mm, annual average temperature of 19~23 ℃, frost-free period of about 310 d, very suitable for planting corn. To make corn revenue, increase market prices, many farmers have opted for early spring planting corn. However, due to technical and management is not in place, the emergence of corn by early spring cold damage, poor results and so on. Discussed this issue and propose appropriate solutions in order to provide the experience and lessons for planting activities.
