The latest reasons for the low yield of Gastrodia elata

Gastrodia elata is a unique valuable traditional Chinese medicine in China, which has strong medicinal efficacy. It can not only be used in medicine, but also an important food often used to make medicinal diet in daily life. The lack of wild resources makes its artificial cultivation begin to rise, but many drug farmers have a very low yield when planting, resulting in low income. So what is the reason for the low yield of Gastrodia elata? Let's take a look.

1. The quality of Armillaria mellea is poor

Armillaria mellea is the main source of nutrition of Gastrodia elata, so the quality of Armillaria mellea is closely related to the yield of Gastrodia elata. In production, it is generally necessary to go through many operations such as detoxification and separation before it can be cultivated with this strain to maintain its quality. However, some drug farmers in order to save costs and improve profits, when choosing Armillaria mellea, choose some common bacteria, or use some old bacteria as strains, which leads to strain degradation, reduced vitality, so the yield is not high.

2. Degeneration of hemp seed

In the cultivation of Gastrodia elata, hybrids are generally used, such as corn, soybeans and other crops, the hybrid varieties have strong vitality and higher yield. However, most of the traditional Gastrodia elata is handed down from generation to generation, in order to save costs, has been using the principle of self-propagation and self-use, resulting in the phenomenon of degradation of flax seed, the vitality is getting lower and lower, so the output is not as good as year after year.

3. Soil permeability is poor.

Any biological growth is inseparable from breathing, animals, plants are also the same, generally in the cultivation of Gastrodia elata is generally the use of coarse sand or choose loose, humus soil. If the planting soil is too sticky or fine sand, it will lead to poor soil permeability, making it unable to breathe normally, thus affecting the yield.

4. Stagnant water

Although Armillaria mellea can survive in water, Gastrodia elata, as a plant, does not have this ability to survive underwater. If there is too much water in the soil or the low water level is high, it will lead to a large area of death and decay in a short period of 2-3 days.

5. Diseases and insect pests

Diseases and insect pests have always been a major reason affecting the development of medicinal materials, Gastrodia elata in the cultivation of moist diseases and insect pests are less, but if the fungus and Linden wood are not sterilized, they carry other fungi. They will affect the growth of Armillaria mellea, and Armillaria mellea seize nutrients, compete for territory, so that it can not grow normally, and Gastrodia elata can not absorb nutrients normally, resulting in underground production. In addition, pests are mainly underground pests, which nibble on hyphae and their rhizomes, resulting in reduced production.

The above is the introduction of the reasons for the low yield of Gastrodia elata. I hope it can help you. If you want to know more about it, please follow us.
