【摘要】 根系的生长及分布状况对沙地植物的生长发育具有重要意义。对章古台地区主要造林树种樟子松的根系在土壤中的垂直分布状况及其对不同深度土壤的改良效果进行了研究,结果表明:从根系状况看樟子松适合于沙地造林,但是纯林中的樟子松到一定年龄后,土壤养分状况有所下降,因此单一的造林方式并不适合于沙地造林。更多还原

【Abstract】 The growing of root system and status of distribution are of very important for the growing of plants in sandy area.The paper studies the vertical distribution of root system in soil of Mongolian Scotch Pine,which is the main species of afforestation in Zhanggutai region and effects of improved soil at different depth.The results show that Mongolian Scotch Pine is suitable for afforestation in sandy area viewing from root system,but,the soil nutrient will be reduced somewhat when simple Mongolian Scotch Pines reach to a certain age.Thus,the single way of afforestation is not fit to sandy area.更多还原
