How to grow ginseng and American ginseng?

Ginseng and American ginseng are a kind of precious medicinal materials. They are planted more. Today, I will share with you how to fertilize ginseng and American ginseng.

Ginseng and American ginseng are perennial perennial plants and require strict fertilizers. It has been discovered by experts that it is a potassium-producing plant, and its absorption of potassium is much larger than that of nitrogen and phosphorus. That is to say, potassium is an important factor in determining whether ginseng is high-yield. And with the addition of years of growth, 4 to 5 years old ginseng has the highest demand for nutrition. So how do you grow ginseng (American ginseng)?

Nitrogen can promote the formation of chlorophyll and the growth of stems and leaves, so that ginseng develops vigorously; phosphorus can promote the development of ginseng roots, make the seeds full, and enhance the ability of cold resistance, drought resistance and salt and alkali resistance; chasing potassium will improve photosynthesis, enhance stems and promote Root development, delaying aging, improving yield and quality. However, it should be reasonable when used.

The NPK share of ginseng is roughly 2:0.5:3. The share of NPK in this share includes available nutrients that can be utilized by nutrition and their needs. The characteristics of soil fertilization in the main producing areas of ginseng were as follows: total nitrogen, alkali nitrogen content, high total phosphorus content, but lack of available phosphorus, medium or lack of useful potassium. Therefore, experts have proposed plans to control nitrogen fertilizer and increase potassium fertilizer.

Since phosphorus is easily fixed in the soil, the application amount of phosphorus is increased, which is why the content of phosphorus in the three elements is much larger than that of nitrogen. The three-element fertilizer with a high phosphorus and potassium content of 10-23-12 N, P and K is just satisfactory for the growth and development of ginseng.

Reasonable allocation of ginseng, American ginseng organic fertilizer and chemical fertilizer:

1. Farming and new planting sites can be used for Shierkang 0.75? 1.25 kg + three elements 0.4? 0.5 kg / zhang.

2.2? 3 years old and 4? 5 years old: available Shierkang 0.75? 1.25 kg + three elements 0.4? 0.5 kg / zhang. It is the combination of NPK that should focus on the degradation of pesticide and fertilizer residues, improve soil quality, and rich in micro-organisms.

3. Topdressing can be applied to Shierkang Shenjin 1 kg / Zhang + three elements 1 kg / Zhang; or diammonium 1 kg / Zhang or stone 2? 5 kg / Zhang + potassium sulfate 0.5 kg / Zhang; or Shierkang ginseng Fertilizer 1 kg / Zhang + diammonium 1 kg / Zhang or stone 2? 5 kg / Zhang + potassium sulfate 0.5 kg / Zhang. Use the application to combine loose soil and water.
