How to fertilize ginseng and panax quinquefolium?

Ginseng and panax quinquefolium are perennial root plants with strict requirements on fertilizers.Through the research of experts, it is found that it is a kind of kaliophilic plant, and its absorption of potassium is far greater than nitrogen and phosphorus, that is to say, potassium is an important factor to determine whether ginseng is productive.And with the addition of growing years, 4?5 years raw ginseng has the highest demand for nutrition.So how to fertilize ginseng (panax quinquefolium)?
Nitrogen can promote the formation of chlorophyll and the growth of stem and leaf, and make the ginseng grow strongly.Phosphorus can promote the development of ginseng root system, make the grain plump, strengthen the ability of cold resistance, drought resistance and salt alkali resistance.Potassium can improve photosynthesis, strengthen stem, promote root development, delay senescence, improve yield and quality.But use it in a reasonable way.
The proportion of NPK needed for ginseng is approximately 2:05:3, which contains available nutrients and available nutrients that we need to apply.The characteristics of soil fertilizer supply in the main producing areas of ginseng were as follows: high contents of total nitrogen and alkali-hydrolysis nitrogen, high contents of total phosphorus, but lack of available phosphorus and available potassium.So experts are proposing a plan to manipulate nitrogen fertilizer and increase potash.
Since phosphorus is easily fixed in soil, the application of phosphorus must be increased, which is why the content of phosphorus in the three elements is much higher than nitrogen.N, P, K share of 10-23-12 tri-element fertilizer with high content of phosphorus and potassium just satisfied the growth and development needs of ginseng.
Suggestions on rational allocation of organic fertilizer and fertilizer of ginseng, panax quinquefolium and panax quinquefolium:
1. Farming and new planting sites available at silcon 0.75?1.25kg + trielement 0.4?0.5kg/meter.
2. 2?Student: three years and four?5 years: available at 0.75?1.25kg + trielement 0.4?0.5kg/meter.It is in the nitrogen, phosphorus and potassium cooperation application together should pay attention to decompose pesticide and fertilizer residue, improve soil quality, rich in many kinds of microelement bacteria fertilizer.

3. The fertilizer can be applied with 1 jin/zhang + 3 elements 1 jin/zhang;Or diammonium 1 catty/zhang or overstone 2?5 jin/zhang + 0.5 jin of potassium sulfate;Or silcon ginseng fertilizer 1 jin/zhang + 2 jin/zhang or overstone 2?5 jin/zhang + 0.5 jin of potassium sulfate.Select spread and combine with loose soil and sprinkling.
