摘要
本文以容重处理的田间和微区床土进行了栽参试验研究。结果表明,土壤容重对床土持水性影响很大,改变床土孔性,使有效水和无效水分布发生变化;适当增加床土容重,有助于人参生长,提高人参表观品质,与最低床土容重处理相比,田间试验4年生和5年生人参单株增重率分别为8.3％和46.4％,微区试验3年生人参单株增重率为44％左右。
This paper deals with Ginseng growth in bed soils with different bulk density on field and microzone. The result showed that the characteristics of moisture retention and pore property of bed soils were affected intensively by soil bulk density. Increasing soil bulk density properly is favourable to Ginseng growing and to getting good quanlity, and the weight of per Ginseng body rised about 8. 3% and 46. 4% in the fourth year and fifth year on field, and 44% in the third year on microzones, respectively.
