摘要
试验针对西昌洋葱种子生产夏季易出现极端高温的难题,建立顶部遮阳网,在0-100%幅度内调控设施棚光通量,通过遮光进行温控。对设施棚不同部位温度与设施棚外的温度变化分析研究表明:在夏季高温时择时用遮阳网在0-100%的范围内覆盖调控光照,降温效果明显,能显著改变设施棚内的局部环境,有利洋葱种子的开花结实。
Testing to the problem of extreme high temperature for Xichang onion seed production in summer, the top of the shade is established, in the 0-100% within the range of the control facilities shed luminous flux, the temperature is controlled by shading. The different part temperature of the facility shed and the temperature variation outside facilities shed showed that in the summer high temperature timing with sunshade net in the range of 0%-100% coverage of controlling light, the cooling effect is obvious, which can significantly change the local environment of the facilities shed and is favorable for onion seeds flowering and fruiting
