过去几年以来,我省每年采集杉木种子30多万斤,但种子质量不高,发芽率都在30%以下,有的还不到20%,原因主要有两方面:①对提高种子质量的重要性认识不够,从数量方面考虑多,认为每年采种任务大,如果要求质量,就不能完成任务,把数量同质量对立起釆,对保护种源,选育良种,提高种子质量抓得少。②缺乏具体措施,对母树林不加选择,采收不及时,脱粒方法不当和保管不善。1964年我们总结了以往的经验教训,在提高种子质量方面,采取了一些有效措施,取得了一定成绩。全省共采集杉木种子62万多斤,种子发芽率一般达到40%以上,最高的达到70%。单采单收的优势母树林
Over the past few years, the province collected more than 300,000 tons of Chinese fir seeds each year, but the seed quality is not high, the germination rate is less than 30%, and some less than 20%. There are two main reasons for this: (1) The importance of understanding is not enough, from the number of considerations, that the annual task of planting a large, if asked for quality, they can not complete the task, the number of anti-quality precautions preclude the protection of provenance, breeding varieties, improve seed quality grasp less. ② lack of specific measures, no choice of mother tree, harvest is not timely, improper threshing methods and improper storage. In 1964, we summed up the past experience and learned some effective measures to improve the quality of seeds and achieved some success. The province collected a total of more than 620,000 kilograms of Chinese fir seed, seed germination rate generally reached 40% or more, the highest reached 70%.
