How to plant Huoshan sarcophagus? The main producing area of ​​Huoshan Dendrobium is Huoshan County, Anhui Province, China. It is generally grown on rocks in the valley and is very beneficial for people who often stay up late and drink alcohol. Let's take a look at the efficient planting techniques of Huoshan Dendrobium.
1 Intensive base site selection
The site selection requirements are convenient for irrigation and drainage, sufficient water supply, no pollution, ventilation, and sunny sun. It is best to be a flat land in the mountainous area with low transformation cost.
2 cultivation mode
2.1 Ground cultivation
A plastic film is laid on the ground, and the crushed stone with a diameter of about 2 cm is placed on the plastic film to a thickness of 15 to 20 cm, and the bark is 5 to 10 cm thick, and the bark is 0.5 to 1.5 cm in diameter.
2.2 overhead cultivation
20 to 60 cm from the ground, the seedbed can be used with plastic trays, asbestos tiles, bamboo baskets, etc. The substrate is covered with 5-10 cm thick gravel and 5 to 10 cm thick bark.
2.3 three-dimensional cultivation
A method of cultivation that uses multiple layers of space in a tree or a special shelf.
3 base construction
3.1 Land leveling
Ditching and paving to ensure smooth water flow, no siltation, easy to walk.
3.2 shed construction
The width is 6m, the height is 3m, the arch spacing is 65cm, the 3 vertical 4 cards, the shading net shading rate is 75% to 85%, and the inner film is covered as needed.
3.3 sprinkler irrigation system
The reservoir is constructed with a water storage capacity of 5t/667m2, and the nozzles are inserted and suspended.
3.4 cultivation substrate
Crushed stone, bark, sawdust, peanut shell (the matrix of organic materials requires fermentation treatment, removing harmful substances such as turpentine oil).
4 seedling selection
The planting of Huoshan Dendrobium is the most important for seedling selection, which is directly related to the survival rate of cultivation and the yield in the later stage. And now there are fewer seedlings in the market, and there are more fakes. The quality can be judged from the following aspects.
4.1 Seedling quality
The commercial seedlings of Huoshan Dendrobium used for cultivation should be non-polluting, no rotten stems, rotten roots, yellow leaves; more than 2 leaves, normal unfolding, leaf color green or emerald green; more than one root; qualified seedlings should be in total seedling volume More than 90.
4.2 Resistance to dehydration
Whether the leaves are wilting, yellowing, or falling off within one week after cultivation.
4.3 Rooting situation
Is there a new root in a week to a half month?
4.4 Germination
In addition to the new shoots brought out in the bottle, the tissue culture seedlings will produce small shoots at the base of the stem of the tissue culture seedlings after 1 month of cultivation.
5 Cultivation management
5.1 seedlings
The cultivation of Dendrobium huoshanense is generally carried out in a cluster. Take 5 to 8 strains as 1 bundle, plant 1 hole, the plant spacing is 10 cm × 10 cm, and the root should be laid flat when planting, and the stem base should be exposed.
5.2 Water Management
The culture substrate of Dendrobium huoshanense maintains a water content of about 50%. After pouring in the morning, the surface air drying in the evening is appropriate.
5.3 Scientific Fertilization
According to 667m2, apply about 250kg of sheep manure or 100kg of rapeseed cake as base fertilizer, and later apply to decomposed organic fertilizer. You can also use slow-release compound fertilizer or more flowers, potassium dihydrogen phosphate and other foliar fertilizers. concentrated. Fertilization should be applied in small quantities and no longer applied after October.
5.4 Pest Management
The prevention and control of the pests and diseases of Dendrobium huoshanense is mainly based on prevention and treatment. The main diseases are: soft rot, chalk disease, leaf spot disease; the main pests are: Spodoptera litura and aphids; and snails, cockroaches and other molluscs.
5.5 winter warmth
It is covered with a 7~8-thick plastic film outside the sunshade net, and the shed head and all around it are compacted to prevent leakage of air and cold air, and to reduce the accumulation of winter snow.
6 harvesting
The tissue culture seedlings are planted twice and then planted twice, and can be harvested in the 7th year, and the transplanted seedlings can be harvested in the third year. After entering the harvest period, Dendrobium huoshanensis can be harvested annually, and the harvesting period can reach several decades. The harvest of Huoshan sarcophagus was carried out in 10~11 months. The stems are greenish brown, and the stems that have naturally fallen off are mature stems, which are cut from the roots. Under the forest, it is cultivated in the wild, and the fresh stems can be harvested 50-100g per square meter. The high-yield cultivation of the facility is calculated according to the planting density per 500 plants/m2, and the fresh stem yield of rice bran, iron skin and copper skin is about 200g, 2000g and 1500g.
The above is all about the planting techniques of Huoshan Dendrobium today. If you are interested in growing this variety, please consider it according to the actual situation!
