摘要
本试验选取了拜泉县幼龄云杉纯林土壤、大豆土壤、落叶松—美国红云豆农林复合经营型土壤、杨树—水飞蓟和杨树—板蓝根林药复合经营型土壤等5种土壤类型作为研究对象,研究各种农林复合经营条件对土壤化学性质的影响。研究结果表明:实行农林复合经营对土壤化学性质有显著的影响,并因作物的品种而存在差异。总体来看,只要选择适宜的间作品种,一般对林地的土壤都有良好的改善作用。在本试验选择的3种农林复合经营类型中,杨树—板蓝根效果最好。
Taking five soil types （soil of pure forest of Picea asperata with young age, soil of soybeans, soil of compounding management of forest and agriculture of larch-American red cloud heans, compounding management of forest-medicine of poplar-silybum mariamum and poplar-dyers woad root） in Baiquan County as research objects, the effect of each kind of compounding management condition of forest and agriculture on soil chemical property is studied. Results showed that in compound management of forest and agriculture it is obviously existed the effect on soil chemical property, and there is difference because of variety of the crop. All in all, selecting optimal intereropping varieties should improve the soil effectively in forest land. In 3 kinds of compounding management of forest and agriculture selected in this test, the effect of poplar-dyers woad root is the best.
