山海关区位于河北省秦皇岛市东北部,采用日光温室种植生菜已有10多a的历史,生菜年种植面积近0.13万hm2,平均667 m2产3500.00 kg左右,总产量约7万t。产品主要销往北京、天津及东北三省的主要城市,具有较高的市场知名度。为提高日光温室生菜安全生产规范化水平,以大量的田间调查试验、地力检测和相关知识为基础,通过品种选择、土壤处理、栽培模式、肥料应用、温湿调控及病虫害防控等生产全过程关键点的科学调整,形成了一套相对完整的安全栽培技术。
Shanhaiguan District is located in the northeast of Qinhuangdao City, Hebei Province. It has a history of more than 10 years to grow lettuce in sunlight greenhouse. The annual planting area of lettuce is nearly 13,300 hm2, with an average of 667 m2 and 3,500.00 kg. The total output is about 70,000 tons. The products are mainly sold to major cities in Beijing, Tianjin and the three northeastern provinces, with high market popularity. In order to improve the standardization of safe production of lettuce in solar greenhouse, based on a large number of field investigation, field testing and related knowledge, the key to the whole process of production including variety selection, soil treatment, cultivation mode, fertilizer application, temperature and humidity control and pest control Point of scientific adjustment, formed a relatively complete set of security technology.
