过去我们的日光温室一年只种植两茬,并且有80％是黄瓜和番茄,667平方来最高年收入只有1—1.5万元。为了提高单位面积产量,获得最佳经济效益,我们进行多茬立体高效栽培的探索,一年内种植4茬,一茬丝瓜、一茬茼蒿、二茬芹菜,使667平方米年产量达20000公斤左右,年收入 In the past, only two crops were planted in our solar greenhouse a year, and 80% of them were cucumbers and tomatoes. The highest annual income of 667 square meters is only about 1-1000 yuan.
