- Abstract:
- With the engineering of environmental geological restoration of abandoned mines rock slope of the Qinglong mountain in Nanjing，the temporal characteristics of base material nutrition through a series of testing and analyzing of nutrient components of the spraying base material were analyzed.The results showed that the contents of the available organic matter,total nitrogen,available nitrogen,available phosphorus and available potassium tended to decrease.It decreased by 4.05%～8.26%,1.78%～2.10%,8.46%～11.24%,1.10%～1.65%,9.35%～14.45% in the third year after spraying，respectively.Among the lower slope position，the middle slope position and the upper slope position,the available organic matter，available nitrogen and available phosphorus had showed more remarkable difference（P＜0.05）among different slope positions each year after spraying,respectively.The available potassium content had showed extremely significant differences（P＜0.01） in the first year after spraying and significant difference （P＜0.05）in the second and third year after spraying among different slope positions.The available organic matter and total nitrogen contents had showed consistent trends：the middle slope position＞the lower slope positio＞the upper slope position.The available nitrogen,available phosphorus and available potassium contents had showed consistent trends the lower slope position＞the middle slope position＞the upper slope position，each year after spraying,respectively.
