四川省盐边县北部地区早春有着丰富的光热资源,月温差较小,日温差较大,特别适合早春四季豆的种植。沿湖(二滩库区)、河谷地带土壤肥沃,水利条件好。正如永兴镇沿湖河谷一带,属于亚热带干热河谷气候区,光照充足,早春虽干旱,但沟渠灌溉条件好,河谷地区农业基础设施相对完善,水热条件好。种植期1——4月期间日照时数多于1220小时,平均气温11-23℃无霜期110天左右,非常适合早春四季豆的种植。在其他地区上市之前出售价格较高,许多农户都选择种植早春四季豆。但由于技术和管理不到位早春四季豆受低温、虫害,出现结荚不好的现象。本文就此问题提出一些解决办法和相应的技术。
The northern part of Yanbian County in Sichuan Province has abundant light and heat resources in early spring, with small monthly temperature difference and large daily temperature difference, which is especially suitable for planting early spring green beans. Along the lake (Ertan reservoir area), valley fertile soil, good water conditions. Just as the area along Yanghu Valley in Yongxing Town belongs to the subtropical dry-hot valley climate zone, there is sufficient sunshine. In the early spring, although the drought is good, the canal irrigation conditions are good. The agricultural infrastructure in the valley area is relatively sound and the hydrothermal conditions are good. Planting period from January to April more than 1,220 hours of sunshine hours, the average temperature of 11-23 ℃ frost-free period of about 110 days, is very suitable for the planting of early spring beans. Before selling in other areas higher prices, many farmers have chosen to grow early spring beans. However, due to technical and management is not in place early spring green beans by low temperature, pests, pod bad phenomenon. This article put forward some solutions to this problem and the corresponding technology.
