人参是我国东北的特产经济作物,它的生长要求一定的土壤条件,为了扩大人参生产,我国已有多年栽种人参的历史,但人参一般不宜连栽,连栽人参生长不良,不仅产量低,而且质量也差,因此,栽种人参的土壤,在人参收获后,需要撩荒多年,才能进一步栽种人参.人参不宜连栽的原因很多,土壤的立地条件是其主要原因,土壤营养状况的改变,毒素物质的积累,以及病害的发生,均能影响人参的生长,本文主要以土壤作为一个整体,从土’壤代谢角度出发,阐述由于栽种人参所引起土壤状况的改变,找出人参不宜连栽的土壤条件,为进一步扩大人参种植创造适宜的土壤条件提供土壤生物化学方面的依据.
Ginseng is a special economic crop in northeast China. Its growth requires certain soil conditions. In order to expand the production of ginseng, ginseng has been planted for many years in our country. However, ginseng is generally not suitable for planting even with ginseng growing poorly, not only with low yield but also with low yield Therefore, planting ginseng soil, after ginseng harvest, you need to put aside for many years in order to further grow ginseng.Ginseng should not be planted for many reasons, the site conditions of soil is the main reason for the changes in soil nutrients, toxins The accumulation of matter and the occurrence of disease can affect the growth of ginseng. In this paper, the soil as a whole, from the perspective of soil metabolism, elaborating on the change of soil conditions caused by planting ginseng, Soil conditions, in order to further expand the ginseng planting to create suitable soil conditions to provide soil biochemistry basis.
