摘要
为了提高冬季日光温室温度,保证蔬菜的正常生长,将新型太阳能吸热涂料涂刷于日光温室后墙,测试其对温室温度及种植蔬菜产量的影响。试验结果表明,使用吸热涂料的日光温室(E3)在全天各时段的温度均比对照(E6)高,且平均温度可提高2~10℃;E3内种植的宝塔菜花产量较E6提高16.4%,经济效益每667 m^2可增加1395元。
In order to increase the temperature of solar greenhouse in winter and ensure the normal growth of vegetables,new solar heat-absorbing coating was painted on the rear wall of the solar greenhouse to test its influence on greenhouse temperature and vegetable yield.The results showed that the temperature of the solar greenhouse(E3)using the heat-absorbing coating was higher than that of the control group(E6)at all times of the day,and the average temperature could be increased by 2 to 10℃.The yield of cauliflower grown in E3 was 16.4%higher than that of E6 and the economic benefits could be increased by 1395 yuan per 667 m^2.
