| 摘 要： | 以绿色20目、银灰色22目防虫网和日本早生华京青菜品种为试材,采用立柱框架式网室栽培,研究了不同颜色防虫网覆盖对网室内温度、湿度、光照等小气候及华京青菜生长、产量的影响。试验结果表明,与露地相比,防虫网内相对空气湿度增加,晴天和阴天湿度增幅明显比雨天高;光照强度减弱,网色越深减幅越大;夏季覆盖绿色防虫网温度略有降低,秋季覆盖银灰色防虫网温度略有增加。覆盖防虫网后,绿色网内青菜出苗延迟,略有减产;银灰色网内青菜出苗提早,有显著的增产作用,且两者收获期均推迟,商品综合性能均强。

| Abstract: | Taking green （20 mesh） and silvery gray （22 mesh） insect-proof screens and the Japanese early-maturing greens cuhivar Huajing as materials, we studied the effects of covering different colors of insect-proof screens on the microclimate such as temperature, moisture, illumination and on greensI growth and yield in the pillar frame-type insect-proof screen cultivation. The results showed that, compared to the open field cultivation, the relative humidity was increased in insect-proof screens, and the increasing range was larger in sunny and cloudy days than that of the rainy days. The illumination intensity was decreased, and the decreasing range was increased as the screens＇ color deepened. The temperature was decreased slightly covered by green insect-proof screen in summer, and was increased slightly covered by silvery gray insect-proof screen in autumn. In the green insect-proof screen, the greens＇ germination was delayed and the yield was reduced, while in the silvery gray insect-proof screen, the greens sprouted earlier and the yield was obviously increased, and in both the two screens, the greens＇ harvesting period was delayed, but the greens possessed excellent quality. |
