| 摘 要： | 采用野外调查和室内测试相结合的方法,研究了水分对栗钙土理化性质和杨树生长的影响.结果表明:由于过水林地比未过水林地具有较低的容重和土壤硬度、较高的土壤持水能力以及较高的有机质、全氮、全磷和有效氮含量,使得过水林地上杨树人工林的直径、树高和材积生长量、各级根系长度、根系总长度和根系总生物量整体上超过来过水林地.

| Abstract: | The Effect of moisture on physicochemical properties of chestnut soil & growth of poplar was studied by using the method of combination of field investigation & laboratory testing.Result shows that lower bulk density and soil hardness,higher water holding capacity and organic matter,total N,total P,available N are in the woodland with surface runoff than that in the woodland without surface runoff;larger increment of DBH,tree height,volume growth,root length,total length of root,total biomass of roots at al... |
