【摘要】 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更多还原

【Abstract】 Light intensity,temperature and relative humidity in plastic sheds for Strelitzia reginage were measured on January 27th and 28th and February 1st, 2nd, 7th and 8th.It was concluded that light intensity within the sheds could meet the requirement of the growth of S.reginage for only 3 hours even on sunny days.New plastic film or cleaned film improved the light intensity effectively and suitable temperature lasted 6～8 hours in the sheds while outside the sheds it lasted only 4～5 hours.Relative humidity within the sheds was 11%～48% higher than without. Such data are considered to be of value to the management of plastic sheds for S.reginale.更多还原
