本文以浙江省千岛湖姥山林场柏木种子园为对象，对柏木球花及花粉的生态学特性进行了研究结果表明，柏木的雌雄球花在树冠中呈成层分布；降雨时，雄球花对花粉具有保护功能；柏木花粉体积小，重量轻，花粉量大，花粉的散发受气温、风力、相对湿度和气压的综合影响，其中气温是主导因子，风左右着花粉的传播，降雨加速花粉的沉降。

First 27 rabbits of the experimental group were destabilizated by operated on L6、7.Inj Diazepam 0.25 mg/kg,Inj Ketamine 0.02 g/kg and Inj Atropine 0.125 mg/kg was one by one injected into the rabbit through the auris vein,shearing the rabbit hair of backside waist,fixing the rabbit on operation table in face lying,using 1% Povidone Ioding to degerm the operation area.Every rabbit was incised at the backside of its waist,that incisal opening is located in the center of the intervertebral space (L6、7 space) that both side iliac crest line correspond ,from the meso-ordinate direction cut about 4 cm incision,cutting open skin and subcutaneous tissue,thoroughly ,exposing the spinous processes the vertebral plates and the upper-inferior articular processes,entirely segregating the muscles that cohere the spinous processes the vertebral plates and the articluar process,then excising the supraspinal ligaments and interspinal ligaments,biting off two sides the inferior articular processes of L6,in order that resulting in intervertebral destabilization,using 0.9% Inj.Sodium Chloride to washout the incisal opening,in order sewing up each layer tissues.

方法］ 取48只6个月龄日本大耳白兔，雌雄不限，体重为（2.5±0.2） kg，随机进行分组，分为对照组和实验组，对照组为21只；实验组为27只；先将实验组兔腰背部皮毛剪除，用安定注射液1.25 mg/kg、氯胺酮0.02 g/kg、阿托品0.125 mg/kg顺次耳缘静脉注射麻醉后，俯卧固定于手术台上，用1%碘伏消毒手术区域，以髂嵴平对椎间隙（即L6、7）为中心，从正中取一长约4 cm纵行切口，切开皮肤及皮下组织，锐性分离，暴露棘突、椎板及上下关节突，将附着于棘突、椎板及小关节的肌肉全部分离开，然后依次切除L6、7棘上及棘间韧带，咬除第6腰椎两侧下关节突，造成椎间失稳，用无菌生理盐水冲洗切口，依次缝合各层组织；术后动物在笼中自由活动。
