| 摘 要： | 对8年生马尾松人工林开展不同间伐强度研究,并对各种间伐强度林地土壤理化性质进行测定。结果表明,随间伐强度增大,马尾松人工林平均树高、胸径、蓄积量、冠幅、生长量增加,林分群体生产力提高。林地土壤自然含水量、贮水量增大,而通气度、总孔隙度下降,土壤有机质、全N、全P、水解N、速效P、速效K含量增加。

EFFECTS OF THINNING DEGREE ON THE GROWTH AND SOIL FERTILITY OF PINUS MASSONIANA PLANTATION |
| |
| Abstract: | The study of different thinning degrees in eight year Pinus massonina plantation was carried out as well as the physical and chemical properties of soil were tested.The results showed that the growth increment of average height,diameter,volume and crown width were improved with the increasing of thinning degree as well as the soil moisture, storage capcity, organic matter,total nitrogen,total phosphorous, available nitrogen, available phosphorous,available potassium while aerating degree and total degree were reduced. |
