If you plant water on the plain, you can harvest ginseng quickly, but what's the point? The quality of ginseng is too poor. This has done too much damage to the land. It is said that ginseng has a strong ability to absorb fertilizer. If you plant ginseng once, I'm afraid the land will not be viable for many years. Shandong's land is also very precious.
