| 摘 要： | 白皮松是我国北方的特有树种，目前已成为城市和庭园绿化的优良树种。根据其生物学特性，在朝阳县林场苗圃地，进行了地膜覆盖育苗试验，取得了较好效果，文章就该树种的地膜覆盖育苗技术进行了报道。经不同时期的苗木生长情况比较看出，不覆膜的对照区，苗木速生期比覆膜的迟到10多天；从苗木质量来看，覆膜的苗木顶芽封顶已达92．3％，而对照区很少形成顶芽；从产量看，覆膜育苗的产苗量达165万株/hm^2，而对照区仅为130．5万株／hm^2。

| Abstract: | Pinus bungeana is a special tree specie in northern China, it has become a fine tree in beautifying cities and gardens. According to its biological characteristics, seedling cultivation experiments mulching by plastic film are carried out in nursery of Chaoyang County forest farm and fine results are achieved. The results show that: fast growing stage of control is about 10 days later than that of mulching treatments by comparing growing status of seedlings in different periods; judging by the quality of seedlings, the closing-off rate of end buds of mulching seedlings is up to 92.3%; judging by the yield of seedlings, yield of mulching treatments is up to 165 ten thousand stems per hm 2 , yield of control is only up to 130.5 ten thousand stems per hm 2 . |
