为了解决长白山高寒山区由于林木生长期短,落叶松苗木当年难于出圃的问题。我们于1986、1987连续两年在兴参苗圃进行了用塑料薄膜罩播种落叶松的育苗试验。试验证明此法能克服长白山高寒山区变化无常的气候条件,提高地温延长苗木的生长期,当年苗高平均达19.4厘米,比常规育苗高2.4倍,地径平均达0.43厘米,比常规育苗大1.9倍,达到了当年出圃的标准。而且簿膜罩移动方便,有利于圃地耕耘作业,用后又
In order to solve the arctic mountainous area of Changbai Mountain, due to the short period of tree growth, larch seedlings were difficult to go out to nursery problems. In 1986,1987, we conducted seedling experiment of sowing larch with plastic film cover in Xingsen nursery for two consecutive years. Experiments show that this method can overcome the climate change in Changbai Mountain alpine mountain climate conditions and improve the growth of seedlings of the ground temperature to extend the average height of 19.4 cm when the seedling height 2.4 times higher than the conventional seedling diameter averaged 0.43 cm, Times, reached the standard out of nursery. And book film cover easy to move, is conducive to nurturing the garden, after use
