不同苗木种类在煤矿废弃地植被恢复中的试验研究

Research On The Test Of Different Seeding Species On The Coal Vegetation Recovery

采用单因素随机区组设计试验,研究了裸根苗、带土球苗和容器苗在煤矿废弃地植被恢复过程中的生长情况。试验结果表明:不同种类苗木生长情况不同,苗木成活率、地径生长量以容器苗最高,分别为91.58%、6.71,以裸根苗最低,分别比容器苗低31.5%、79%;株高生长量以容器苗最高,为10.08,以带土球苗最低;苗木整体生长状况级以容器苗最好,能够很好地适应煤矿地生长环境,生长旺盛;煤矿地土壤条件差,在植被恢复过程中植物易采用容器苗以提高植株成活率,从而也提高了生态恢复效率。

The research employed single factor randomized block group design test to study the bare root seedlings, soil ball seedlings and seedlings in containers in the coal mine abandoned vegetation recovery in the process of growth. The results showed that different kinds of seedling growth situation were different and the seedling survival rate, diameter increment in the container seedlings were the highest for 91.58%, 6. 71 for bare root spectively which were the lowest than container seedlings lower 31.5%, 79%. The increment of tree tainer seedlings was the highest with 10.08 to seedlings with soil ball is the lowest. The growth of container seedlings well adapted to the coal mine to growth environment, vigorous tions of coal mine. In the vegetation restoration process, the plant is easy using container crease the survival rate of plants, thereby it was necessary to improve seedlings seedlings, re- height to con- of the overall growth, poor soil condi- seedlings in order to in- ecological recovery efficiency.
