雪松是原产于喜马拉雅山的高山树种,用种子进行实生育苗存在出苗少,成苗率低等问题。为了探索雪松播种育苗技术,做到出苗多,出苗一致,出好苗,出壮苗,我们于1985年3月开始,在长沙县进行了育苗试验。一、试验概况雪松种子系澳大利亚进口,每斤4813粒,其中虫蛟霉变和干瘪等废种有251粒,占6.5%。苗圃地为四纪红壤地区的稻田土,1984年曾育过湿地松苗,土壤pH值为4.97,粘性较强。
Cedar is native to the Himalayas mountain species, there are seedlings with seedlings emergence of seedlings less, the problem of low seedling rate. In order to explore cedar sowing seedling technology, so that the emergence of more, emerge the same, a good seedlings, a strong seedlings, we started in March 1985, conducted in Changsha County nursery test. First, the test profile Cedar seeds imported from Australia, 4813 catties per kilogram, of which worms mildew mildew and shriveled and other waste species 251, accounting for 6.5%. The nursery area is a paddy soil in the red soil area of the Fourth Century. In 1984, P. elliottii was bred. The soil pH value was 4.97 and its viscosity was high.
