老参地问题虽被人们注重已久,但目前还不能实行连作,仍需要伐林开垦新土,显见,林与参的矛盾将会日渐突出。特别是近几年来大力发展多种经营事业,参场、林场、农村社队的人参生产面积不断扩大,弃用的老参地相应也越来越多。因此,参后还林的生产和研究工作愈发显得重要。为了探讨老参地土壤养分状况和物理性状上的变化,对树木生长的影响程度,参后还林的效果,以及适宜造林树种问题,试图给参后还林工作提供点滴依据。1982年我们在辉南森 Although the issue of the old ginseng land has been paid attention to by people for a long time, it is still not possible to carry out continuous cropping work yet. Therefore, it is still necessary to reforest the new soil. It is obvious that the contradictions between the forest and the ginseng will become increasingly prominent. Especially in recent years, vigorously develop a variety of business undertakings, ginseng, forestry, rural community ginseng production area continues to expand, abandoned the old ginseng accordingly more and more. Therefore, it is even more important for the production and research work of participating forests to become more and more important. In order to discuss the change of soil nutrient status and physical properties, the influence degree to the tree growth, the effect of returning the forest to the forest, and the afforestation tree species problem, we try to give a little bit basis to the work of returning the forest to the forest. In 1982 we are in Huinan Sen
