金州区地处辽东半岛,东临黄海,西濒渤海,干山余脉纵横全境,地形为丘陵区。属暖温带湿润季风气候。年平均温度9.3—10.5℃,年均降雨量600mm,由于受海陆影响,春季风大雨少,夏季高温多雨。据1980年林业区划统计,全区有宜林荒山8.2万亩,绝大部分都是高山、远山,土层瘠薄,岩石裸露的石质山。由于植被少,土层薄、肥力低,水分条件差,多次重复造林不成活。为了解决石质山造林“两率”低的难题,从1982—1984年对容器的育苗容器规格、基质配方和容器苗与裸根苗的造林成活率等技术进行了试验。在取得经验的
Jinzhou District is located in the Liaodong Peninsula, east of the Yellow Sea, west of the Bohai Sea, dry mountains and veins throughout the entire territory, the hilly terrain. Is a warm temperate humid monsoon climate. The annual average temperature of 9.3-10.5 ℃, the average annual rainfall of 600mm, due to the impact of land and sea, the spring monsoon rains, the summer high temperature and rainy. According to the statistics of the 1980 forestry zoning, there are 82,000 mu of forest waste hills in the whole region, most of which are alpine and distant mountains with barren soil and rocky exposed rocky mountains. Due to less vegetation, thin soil, low fertility, poor water conditions, multiple repeated afforestation does not survive. In order to solve the problem of “low rate of two rates” in afforestation of stony mountains, experiments were made on the container seedling container specification, substrate formula and the survival rate of container seedling and bare root seedling from 1982 to 1984.
