| 摘 要： | 为了防除青海云杉花期霜冻为害和提高种子产量和质量,研究了不同熏烟处理对花期林间气温、空气湿度、球果鲜重、产种量、出种率、种子千粒重和发芽率的影响。结果表明:青海云杉花期熏烟均提高林间气温、种子产量和质量。其中处理2(4个燃点/667 m^2)的效果最佳,球果鲜重、产种量分别为每株82.14 kg、4.07 kg,出种率、千粒重和发芽率分别为4.95%、8.63 g和86.44%,较对照(CK)分别提高了37.98%、225.60%、135.71%、96.58%和27.81%,差异均达到显著水平(P<0.05)。

| Abstract: | In order to prevent frost damage in flowering phase and increase seed yield and quality of Picea crassifolia,the effects of different smoking treatments on air temperature and humidity between woods,fresh weight of cones,seed yield,seed production rate,thousand seed weight and germination percentage were studied.The result showed that the air temperature between woods,seed yield and quality of Picea crassifolia were studied after smoke application in flowering phase.The effects of treatment two(4 ignition points/667m^2)was the best in all treatments,whose fresh weight of cones,seed yield,seed production rate,thousand seed weight and germination percentage were 82.14 kg/plant,4.07 kg/plant,4.95%,8.63 g and 86.44%,respectively,which increased by 37.98%,225.60%,135.71%,96.58%and 27.81%respectively,compared to CK.The difference was significant(P<0.05). |
