Wu, Yao,Qin, Kailun,Zhang, Jinfu,Li, Fengri Institute of Forest Science 2013 Journal of Forest Science Vol.29 No.4
Based on the guiding ideology of "Close-to-nature forestry", the soil chemical properties of Korean pine (Pinus koraiensis) plantation forest which was early done by canopy gap control were analyzed of Liangshui nature reserve in northeastern China. The results indicated that the nurture of forestry crevice diaphanous tended to improve the soil nutrient contents and significant differences of soil nutrients existed among different levels of soil for the same forest type of Korean pine. At 0< $H{\leq}20$ cm layer, the content of available nitrogen, available phosphorus, available potassium, total nitrogen and total phosphorus in artificial pure Korean pine forest are 640.28 $mg{\cdot}kg^{-1}$, 7.54 $mg{\cdot}kg^{-1}$, 275.91 $mg{\cdot}kg^{-1}$, 1.114% and 0.075%, they all higher than the other kinds of forests and for average 1.1 times, 1.4 times, 1.3 times, 1.6 times and 1.2 times. From the layer of $0<H{\leq}20$ cm to 20 cm < $H{\leq}40$ cm, soil nutrient indicators showed various degrees of decreasing in which organic matter had the greatest decline, decreasing by 170.64% while PH had the lowest decline, decreasing by 4.66%.
