提高大棚蔬菜栽培的经济效益,利用春、夏、秋、冬的气候特点,选用适宜的作物和栽培品种,实行反季节栽培,最大限度的提高大棚的利用率。近年来,我们将塑料大棚两熟制改为三熟制栽培,即:小西瓜——番茄——甜玉米栽培模式。较好的利用了小西瓜的成熟早、上市早、价格高,番茄耐高温、耐干旱,比较适宜夏季栽培,甜玉米耐低温,秋冬季上市价格的特点,大大的提高了复种指数,经济效益也明显提高。
Increase the economic benefits of greenhouse vegetable cultivation, the use of spring, summer, autumn and winter climate characteristics, the selection of suitable crops and cultivars, the implementation of off-season cultivation, to maximize the utilization of greenhouses. In recent years, we will be double-crop plastic greenhouse into three cooked cultivation, namely: a small watermelon - tomato - sweet corn cultivation mode. It is better to make use of the characteristics of early mature, early market, high price, high temperature tolerance and drought resistance of tomato, more suitable for summer cultivation, low temperature tolerance of sweet corn and the listing price in autumn and winter, which greatly improves the multiple cropping index and economic benefits Also significantly improved.
