杉木是我国主要用材树种之一。为了适应林业建设需要,探求质量佳、产量高的种子,供大量繁殖杉木之需,浙江省林业科学研究所曾进行杉木母树受不同光照程度对种子品质和产量影响的试验。现将初步结果简报如下。选择两块土壤条件、林相、母树年龄(23年)、造林方法(扦插造林)、疏密度等均相似,而坡向不同的林分。通过标准地调查,选取标准木,采取种子,进行室内外种子品质鉴定,其结果如下表:
Chinese fir is one of the main timber species in China. In order to meet the needs of forestry construction, explore good quality and high yield of seeds for the need of large-scale propagation of fir, Zhejiang Forestry Research Institute has conducted fir seedlings under different light levels on seed quality and yield test. Now the preliminary results briefed as follows. Select two soil conditions, forest facies, mother tree age (23 years), afforestation method (cuttings afforestation), density and so on are similar, and the slope to different forests. Through the standard survey, select the standard wood, take the seeds, indoor and outdoor seed quality identification, the results are as follows:
