The price of Dendrobium candidum is generally not very expensive. It is a kind of health care products that are relatively close to the people. The price is different because of the origin and the production and cost of the manufacturer. There is no standard price in the market. For a long time, people used this medicine to collect and collect wild resources, while the wild sarcophagus has a very low reproductive rate, low survival rate and scarce production, which led to the endangerment of the top grade of Dendrobium in Dendrobium, which caused its price to soar. From the current market, the price of pure iron maple is ranging from 10-20 yuan per gram, and the price is out of stock. At present, the purchase price of fresh products of Dendrobium candidum is still above 2000-3000 yuan per kilogram.

Fertilization management After the planting of Dendrobium candidum, its late planting management is equally important. Fertilization management is an indispensable step in the late growth of Dendrobium candidum. It is mainly based on the combination of organic minerals and foliar spray. When the crops grow long leaves, and the leaves gradually turn green, some new roots of the crop may be Exposure to the atmosphere requires a substrate to cover it, and at this stage, semi-fertilized cow dung can be used to fertilize the crop. At present, the main fertilization process is as follows: First, the application of foliar fertilizer is mainly for the crop after 7 days of planting; then, according to the actual situation of the crop, the farmer's fertilizer is applied every time, about 50-100 kg/667 m2. Good; in the middle and late October, it is more suitable to apply potassium dihydrogen phosphate, about 20 kg/667 m2; after the spring of the next year, the farmer's fertilizer is applied again, which is most suitable for 50-100kg/667 m2. 2. Pest control Dendrobium candidum is often invaded by pests and diseases during the growth process. Therefore, correct and timely prevention can reduce the damage of pests and diseases to crops. Dendrobium candidum mainly has the following diseases: root rot, black spot and anthracnose, and different prevention measures are taken for different diseases. Such as root rot, which mainly occurs in the rainy season, first causing its roots to rot, and then slowly causing the upper part to wither; its corresponding control method: before the crop planting, the species is 100 times more than 25% carbendazim Soak the wet powder for the appropriate amount of time. Black spot disease is mainly prevalent in the state of low temperature and rainy season. The main damage lies in the leaves and petioles of the crop, so that the leaves can wither; the corresponding control method: spraying the Dendrobium candidum with 51% carbendazim 1000 times solution In general, spraying 1 or 2 times can basically prevent and control. The main hazards of anthracnose are the leaves and fleshy stems. When the leaves are first onset, they are black. Later, the whole leaves are slowly scorched and shed, which eventually leads to crop death. The corresponding control methods: when the initial disease is used, the pruning method can be adopted. It can be removed, and the crop can also be sprayed with 1:1:200 times Bordeaux mixture. 3, harvest The best time for harvesting Dendrobium candidum is about 2 to 3 years after planting, and the most suitable harvesting time is at 3a. Under normal circumstances, the principle of harvesting adopts the principle of “going to stay threeâ€, that is, the stem of Dendrobium candidum is harvested in 3 a or more than 3 a, and the stem below 3 a is reserved for later breeding. Growing. After harvesting, pay attention to spraying protective fungicides in time to prevent the occurrence of diseases.
