林业生产中育苗的关键之一,是促进种子整齐快速的发芽出土。春播未催芽的种子,经过较长的时间才能发芽出土,这影响到苗木的产量和质量。本试验的目的是对几种林木种子用几种介质进行低温层积处理,通过发芽试验,判比各种处理的效果,寻求种子发芽迅速整齐的处理方法。 One of the keys to seedling in forestry production is to promote the germination of seeds quickly and neatly. Spring does not germinate seeds, after a long time to germinate unearthed, which affects the yield and quality of seedlings. The purpose of this experiment is to use several kinds of media for several kinds of tree seeds to carry on the low-temperature layering treatment, through the germination test, judge the effect of various treatments and seek the quick and neat treatment method of seed germination.
