利用塑料大棚种植反季节蔬菜,可取得良好的经济效益,大棚蔬菜反季节高效种植的技术要求如下:(1)抓住关键季节。要获得反季节蔬菜种植的高效益,关键是要抓住“三淡”,即春淡、夏淡和秋淡三个蔬菜生产淡季,搞好蔬菜品种搭配。春淡,以早黄瓜、早辣椒等为主,一般2月初插种,上市比常规提前一月左右。夏淡,以冬瓜、芹菜等为主,4月插种,6月中旬上市。秋淡,以辣椒、黄瓜、西红柿为主。辣椒和黄瓜7月中旬浸种播种,西红柿8月初浸种播种,上市时间均在秋末冬初。三淡上市的蔬菜价格贵,效益好。
The use of plastic greenhouse cultivation of anti-season vegetables, can achieve good economic benefits, greenhouse vegetables efficient planting against the season technical requirements are as follows: (1) to seize the key seasons. In order to get the high efficiency of counter-season vegetable planting, the key is to seize the “three light”, that is, spring, summer and autumn light three vegetable production off-season, do a good job with varieties of vegetables. Spring and early autumn, with early cucumber, peppers and other early, generally early February planting, listing than the conventional one month or so ahead of schedule. Summer light, with melon, celery, etc., mainly in April, mid-June listing. Autumn light, with pepper, cucumber, tomato-based. Pepper and cucumber soaked sowing in mid-July, tomatoes soaked in early August sowing time to market in late autumn and early winter. Three light market price of vegetables expensive, good efficiency.
