根据 1999年 1月 2 7~ 2 8日、2月 1~ 2日 ,7~ 8日塑料大棚内光照强度、温度和相对湿度实测资料进行分析 ,结论是 :棚内光照强度平均透光率 36 .3%~ 47.7% ,晴天只有 3h达到鹤望兰生长要求 ,而新膜及清洁膜面能有效提高膜内光强 ;无滴长寿保温膜覆盖大棚 ,新棚内白天适宜温度持续 6h~ 5h ,棚外仅有 4h~ 5h ;棚内相对湿度比棚外高出11%~ 48% ,仅有 1.5h~ 4.5h为适宜时段。该研究为鹤望兰的生产管理提供依据
According to the measured data of light intensity, temperature and relative humidity in plastic greenhouse from February 27 to January 28, February 1 to February 2, and July 8 to January 8, 1999, the conclusion is: the average light transmittance of the shed is 36 .3% ~ 47.7%, sunny only 3h to reach the growth of Strelitzia reginae, and the new film and clean film surface can effectively improve the light intensity within the film; dripless longevity insulation film covering the greenhouse, the new shed during the day suitable temperature for 6h ~ 5h , Shed only 4h ~ 5h; shed relative humidity higher than the shed outside of 11% to 48%, only 1.5h ~ 4.5h for the appropriate period. The research provided the basis for the production management of Strelitzia reginae
