Abstract: Taking the traditional ＂43 model＂ solar greenhouse as the research object, seven measures were taken to improve the greenhouse performance. The temperature and ground temperature of the greenhouse were monitored in the first half of January, and the early cultivation of cucumber was promoted in the last half of January. The rectification effect, harvest time, yield and benefit of cucumber were compared and analyzed, which provided the basis for the vast number of growers to obtain high yield and maximum economic benefit of cucumber. The results showed that the heat storage and insulation capacity of the optimized solar greenhouse were obviously improved,and the lowest temperature deviation was less than 30%, and the temperature fluctuation was small. In the middle of January, the temperature in the greenhouse was stable through 10℃ and the ground temperature in the 20 cm tillage layer reached 12℃. The greenhouse had the planting conditions for fruit vegetables. Cucumber planting started on January 20, 15 days ahead of CK, 19 days ahead of the initial harvest period and 23 days ahead of the full fruit period. By the end of May, cucumber harvested at 136 200 kg/hm^2 which was 25.8 % higher than CK, realizing 470 800 yuan/hm^2 and increase of 325 400 yuan/hm^2 compared with CK.
