我区从1996年开始对日光温室三茬果菜栽培技术进行了试验研究,采取加大保温、增温、补光措施,在12月末抢早定植第一茬果菜(番茄、黄瓜)。翌年5月1日前采收上市结束,在不影响秋茬生产的情况下,于4月中旬套栽第二茬果菜(旱黄瓜、豆角、厚皮甜瓜等),在7月末8月初定植第三茬果菜。经两年试验获得了成功,并进行示范推广。试验选用八种栽培模式,平均公顷对照增收4.22万元,其中效益最好的栽培模式(番 Since 1996, our district has carried out experimental research on the cultivation techniques of the three cropping fruits and vegetables in the solar greenhouse. Taking measures of increasing the temperature, increasing the temperature and supplementing the light, we first planted the first crop of fruits and vegetables (tomato and cucumber) at the end of December. The end of May 1 the following year, the end of the harvest, without affecting the production of autumn stubble, mid-April planting the second crop of vegetables (dried cucumbers, beans, thick-skinned melon, etc.), in late July and early August planting third Stubble fruit and vegetables. After two years of experiment was successful, and demonstration to promote. The experiment selected eight cultivation modes, the average hectare control income 42200 yuan, of which the most effective cultivation mode (Fan
