摘要
研究北方农田退化黑钙土经过改土施肥处理，对西洋参生长发育的影响。试验结果表明，黑钙土壤中掺２０％草炭灰西洋参根系增长２％，增粗２２％，增重４５％。施混合畜肥体根系增长１８％，增粗３９％，增重４５％。每ｈｍ２（公顷）平均产鲜参１２５０～１５０００ｋｇ。
To study the effect of improving soil and applying manure experiment on growing for Panax Quinquefolium. The result shows that adding 20% plant ash made root system of Panax Quinquefolium increase 2% in length, 22% in thick. The yield of fresh Panax Quinguefolium is 1250～15000kg·hm -2. Many experimental data and main technical points are provided in this paper.
