光照强度对梅花鹿茸生长影响的研究

A STUDY ON EFFECT OF LIGHT INTENSITY OF THE GROWTH OF VELVET ANTLER IN SIKA DEER

文本采用露天电光源控制光周期的方法，探讨了不同光照强度对圈养梅花鹿鹿茸生长的影响。将１６５头雄性梅花鹿分组置于４种光照强度（Ｉ＝１５０、３００、４５０、６００ｌｕｘ）下，每日人工增加光照时数为２.００～６.７５ｈ，观测鹿茸生长发育的情形。在Ｉ≥３００ｌｕｘ时，控光鹿群较对照鹿群平均提前２７.１ｄ脱角生茸和２０.３ｄ换毛；头茬茸平均增产率为２１.４７％，再生茸平均增产率为１７９.１８％。故认为，采用电光源均匀布设时，Ｉ≥３００ｌｕｘ是控光增茸技术中最适光照强度，并可获得较显著的经济效益。

The velvet antler is of a rare traditional Chinese medical material.Photoperiodiccontrol exerts a great effect on the growth of velvet antler in deer.We adapted electriclight source in the open air to increase daylight by 2.00 to 6.75 hours every dayduring a 80～90 day test period over two years.165 male Sika deer(Cervus uipponhortulorum)were exposed to 4 light intensities(I=150;300;450;600 lux,respecti-vely),the different state of velvet antler growth were emerged.In groups of I≥300 lux,the casting and growth of velvet antler began 27.1 daysearlier than that in controls;Molting came 20. 3 days earlier.The rate of increase inyield in the first crop and the second crop of velvet antler was 21.47%and 179.18%respectively.The result shown that with even distribution of electric light source thenotable economic benefits were acliieved when light intensity was equal to 300 lux or more.
