Dendrobium Officinalis is a herb of aerial orchids. The wild “Dendrobium officinalis†is a rare and endangered plant that is protected by the national second grade. Authentic Dendrobium officinalis stems are iron green, gas micro, chewing sticky and sweet. Less slag, with Sheng Jin Yang Wei, Ziyin heat, lungs and kidney, eyesight and strong waist effect. In addition to medicine, Dendrobium candidum is the top grade of diet, and it can be eaten correctly, which can play a special role in enhancing immunity, anti-aging, anti-rheumatism, lower blood sugar and blood lipids. In the process of planting, the choice of substrate has a great influence on the survival rate, growth, reproduction and yield of D. candidum transplant. The experimental summary shows that the bark substrate with air permeability and water retention is the best nutrient soil for cultivated Dendrobium officinale. Based on this, we can use the Gymnosperm stratum nutrient soil fermentation agent to produce the Dendrobium candidum cultivating substrate with high water permeability and water retention properties, so that the survival rate, the later growth and reproduction of the Dendrobium candidum can be ensured while the Dendrobium candidum is successfully cultivated.
1. Dendrobium candidum cultivation substrate
The commonly used substrates for cultivated Dendrobium candidum are mainly bark, aquatic grass, sandstone, and peat soil. Among them, the bark matrix has good air permeability and water holding capacity, which is consistent with the growth characteristics of the Orchidaceae plants, which are hi-breathable and hi-humid, and is more suitable for the cultivation of Dendrobium candidum; the two substrates of peat soil and aquatic grasses are able to grow the Dendrobium candidum. The effects are basically the same, but the nutrient composition and permeability are inferior to the bark matrix. The gravel substrate has a low nutrient content. Although the permeability is very good, it is difficult to satisfy the conditions required for the growth of Dendrobium candidum as a culture medium alone.
2. Self-made fermentation method of Dendrobium candidum
First, prepare a nutrient solution. Urea water is made from 2.5 kg urea to 150-200 kg of water and evenly sprinkled on the material. The moisture content of the fermentation material is required to be controlled between 60% and 65%.
Second, build materials into piles. The general requirements for building a heap fermentation fermenter with good moisture content are: pile height 1.2-1.5 meters, not less than 80 centimeters, width 2 meters, the length of the pile can be freely adjusted according to the amount of fermented material, generally not less than 2 meters in length, The total volume of a single fermenter is not less than 3 cubic meters.
Third, pick up the fermentation strain. After soaking in urea water, cover the air-permeable cover and place it naturally for 24 hours. The next day, mix 2 kg of golden bacon fermenting agent and 5 kg of rice bran into a batch of bacteria and spread it evenly. In the heap of materials, it can be turned side by side, and this process is called “inoculationâ€.
Fourth, cover and tip over. After the species has been planted, cover the air-permeable covering on top of the large pile and shading and shelter from the rain. Under normal circumstances, after the start of the fermentation process, after 5 to 10 days of fermentation, the temperature can reach 55 ~ 60 °C above, then flip once, cumulative 2 or 3 times to complete the fermentation.
Finally, the fermentation is completed. Under normal circumstances, the fermentation time of straw and deciduous substrates is about 15 days, and the matrix of sawdust is 25 to 30 days. The bark can be fermented for 30 to 40 days. The finished material is dark brown, soft and fragile, and can be used after drying.
3, the user admitted that the high yield of Dendrobium candidum
Customers who have used Gymboree have frankly stated that the use of trebic matrix fermentation technology is simple, cost-effective, can significantly increase the yield and quality of Dendrobium candidum, and the technical methods are much better than the traditional method of producing substrates. In addition, the nutrient soil produced by the Kinpo Matrix Fermentation Technology is an ideal seedling flower culture soil material, and has very good economic and ecological benefits.
