长期以来,我国种参社队和国营参场一直保持着原始的种参不上粪的旧习惯,致使我国人参单产低,支头小,赶不上后发展的朝鲜、日本和美国。日本1928年才试栽人参,历史并不长,但是他们在栽人参前一两年进行改士施肥,每公顷施绿肥7,500市斤、饼肥400斤、石灰3,700斤,蚕粪3,700斤或施有机肥7,500—22,400斤,生长季节每年追饼肥230斤。所以日本人参支头小大、单产高,每平方米单产
For a long time, our country’s ginseng community and state-run field have been keeping the original old habit of not participating in manure, resulting in the low-yielding ginseng in our country with small branches and the backward development of North Korea, Japan and the United States.

Therefore, the Japanese ginseng head small, high yield, yield per square meter
