How to improve the survival rate of Dendrobium officinale planting?

Dendrobium officinale is a very precious medicinal material with good medicinal value. The reason why Dendrobium officinale is more expensive is precisely because its survival rate is relatively low, especially in the process of planting, it is easy to have pests and diseases, and it has high requirements for the environment. So what can we do to increase its survival rate?

I want to improve the survival rateFirst of all, we must choose a suitable place for its planting, provide it with a good environment, and usually do a good job of protecting against pests and diseases.

1. Choose a suitable planting area.

If we want its survival rate to increase, we must first choose a good planting site, for example, the largest Dendrobium planting area in our country is located in Yunnan, Zhejiang, Hunan and other places. Therefore, we should first choose a suitable planting site for it, which is also one of the most basic conditions for planting Dendrobium officinale. Although it is more troublesome, it is the most critical step.

Second, the environmental requirements are strict.

The best place to grow Dendrobium is actually at an altitude of about 800 to 1,600 meters. The environment here is very humid and cool, which is suitable for its growth, and the temperature of growth is best controlled at about 15 30 degrees, especially during the growth period, which should be 1 2 degrees higher. When Dendrobium officinale is below 5, it will begin to gradually lose its leaves and cannot grow normally.

When planting dendrobium, the humidity should also be kept at about 80%, it must not be too dry, and remember to keep it well hydrated. In summer, the shading rate reaches 70%, and in winter, the shading rate reaches 30% or 50%, if the sun is too dazzling, it will cause its rhizome to swell, which directly affects its growth. If we are planting in a greenhouse, we must keep the air flowing back and forth.

Dendrobium officinale is a little more troublesome to plant, and some people also like to plant it at home, in fact, the dendrobium we grow at home is not necessarily the most authentic, most of them are mainly ornamental.

First of all, you can choose urea for fertilization, or you can choose phosphate fertilizer and nitrogen fertilizer, and you should also water more at ordinary times, loosen the soil in time, and also need to spray some pesticides in time to remove insect pests, so as to improve the survival rate.

First of all, it is necessary to pay attention to the process of growth must be taken care of, it is best to plant in Yunnan, Zhejiang, Guangdong, Hunan these places, which is very suitable for the growth of this plant, and must be watered and fertilized, and then often deal with weeds, so as to improve the survival rate.

First of all, plant dendrobium in pots, cultivate the roots, and then plant it in the greenhouse after it is fully viable, so that the survival rate will be greatly improved.

A very good temperature should be controlled, and the humidity of the soil must be moderate, and it is necessary to manage some sunlight at all times to prevent pests and diseases in the soil.

Dendrobium officinale is not easy to feed, it has high requirements for the environment, and it is necessary to keep the sail brigade moist and cool when planting, if there is no good position, it is very difficult to grow. Dendrobium officinale likes a cool, warm, half-shaded and half-sunny environment, and grows mostly on loose and deep bark, which requires soil breathability, water filtration, fast growth rate, and strong survivability.

Growth habits of Dendrobium officinalis.

Can dendrobium feed indoors.

Dendrobium officinale can be fed indoors, but it is more difficult to grow indoors, and the requirements for the environment are higher, and it is easy to die if it is not well maintained.

Is the dendrobium I just bought easy to raise?

The newly bought dendrobium is good to feed, first put it in a cool place with scattered light, spray some water, germinate new roots after 10-15 days, and then move to the shade under the shed for maintenance.

How to feed dendrobium.

1. TemperatureDendrobium officinale likes warmth, the growth temperature needs to be controlled between 15 and 30 degrees, and it should be cultivated indoors in winter, not outdoors.

2. WateringDendrobium officinale needs enough water to grow, so it is necessary to observe its dry and wet conditions frequently, generally based on the principle of seeing dry and wet, watering when dry, but can not be watered and flooded, so that it can grow normally, generally watered once every two to three days.

3. Illumination: Dendrobium officinale needs sufficient nutrients to grow better, generally apply special fertilizer, thin fertilizer frequently, and apply fertilizer once every seven days.

Not easy. Dendrobium officinale is suitable for growing in a cool, humid and airy environment. RawAt an altitude of 1,600 meters, it prefers a warm and humid climate and a semi-shady and semi-sunny environment, and is not cold-tolerant.

The cultivation of Dendrobium officinale is required to be carried out in the greenhouse, and the construction of the greenhouse requires ventilation, shade and rain, and insect nets, and according to the growth habit of Dendrobium officinalis, consider the natural factors such as light, temperature, humidity and ventilation of the site. The suitable temperature for the growth of Dendrobium officinale is 15 30.

In Zhejiang, the summer is relatively hot, and 80% of the shade net is generally used to cover it, and the plastic film is lifted to facilitate cooling; The winter is relatively cold, and it is closed with a double-layer plastic film at 30% 50% shading.

Dendrobium officinale requires to keep the substrate moist, and the air humidity is kept above 80%, but it can not accumulate water, and it is best to use sprinkler irrigation or drip irrigation when watering, and it is not allowed to irrigate. The amount of watering varies from season to season to region.

1.Prepare flower pots, pots, plastic pots, wooden pots or clay pots can be used for potting, among which clay pots and clay pots are ideal. Due to its good air permeability, it is suitable for dry cultivation. In addition, it should be noted that the bottom of the basin should have drainage holes and the sides should have ventilation holes, if there is no processing.

2.Soil requirements Dendrobium officinale does not have particularly high requirements for soil, sandy soil or clay and other soils are actually OK, but the soil needs to be fertile, if it is not fertile enough, it is best to add some base fertilizer to make the soil fertile.

3.It is more reliable to choose seedlings from national scientific research units or universities, and it is also a way to find friends with planting experience, if you buy online, you must confirm the reliability of the seedlings, after all, not every kind of dendrobium has medicinal value. First soak the seeds in warm water for 3 hours, then place them on the culture soil in the greenhouse for 3 4 days, keep the temperature at about 20 degrees, and germinate in about 4 5 days, separate the germinated roots, put the roots on the substrate, and then cover the roots with the surrounding substrate, the depth is preferably in a third of the place, and then water a small amount of water.

How to grow Dendrobium

1. Preparation for planting.

Take out the Dendrobium seedlings and wash the roots with clean water. Clay pots, plastic pots, wooden pots or clay pots can be used for potting, among which clay pots and clay pots are ideal. Due to its good air permeability, it is suitable for dry cultivation.

In addition, if the pot is cracked, it should be noted that there should be drainage holes at the bottom of the basin and ventilation holes on the side, if it is not processed.

2. Planting. Plant the dendrobium seedlings into the pot, cover the rhizomes with sawdust and broken bark around them, and pay attention to the amount of silver closure of the seedlings and do not bury the seedlings into the substrate. Soil requirements Dendrobium officinale does not have particularly high requirements for soil, sandy soil or clay and other soils are actually OK, but the soil needs to be fertile, if it is not fertile enough, it is best to add some base fertilizer to make the soil fertile.

3. Watering. After planting, water thoroughly, water with a sprayer, and pour the water on the leaves.

4. Daily maintenance.

It is best to place the plants on a balcony with a shade net to avoid strong light affecting the growth of the plants.

Field management. 1) Watering: In the later stage of Dendrobium planting, the air humidity is too small, so it should be watered frequently to keep the fiber wet, and you can use a sprayer to water in the form of spray.

2) Top dressing: Dendrobium growing in poor land should pay attention to top dressing, the first time before and after the Qingming Festival, nitrogen fertilizer mixed with pig manure and river mud. The second time before and after the beginning of winter, peanut drum, rapeseed cake, superphosphate, etc. were added to the river mud to mix and paste in the roots, and top dressing outside the roots was also acceptable.

3) Adjust canopy density: The density of the growing place of Dendrobium is about 60%, so it is necessary to prune the epiphytic trees frequently to avoid too much shade or insufficient canopy density.

4) Pruning: When the new stem is replanted before spring every year, the dead stems in the bush are cut off in combination with the harvesting of old stems, and the diseased stems, weak stems and sick roots are removed, and after planting for 6 or 8 years, the clumps are turned over and re-branched and propagated according to the growth of the bush.

Pest and disease control.

1) Dendrobium black spot disease: it causes leaf wilting to damage the leaves, which occurs in March and May. Prevention and control method: 50% carbendazim 1000 times liquid spray 1 2 times.

2) Dendrobium anthracnose: for the damage to leaves and stems, brown or black lesions appear on the affected leaves, which occur in January and May. Prevention and control method: spray 2 3 times with 50% carbendazim 1000 times solution or 50% methyl tobuzin 1000 times solution.

3) Dendrobium phenanthrophyllum shield scale: parasitic on the edge or back of the leaves of the plant, sucking sap, late May is the peak of hatching. Prevention and control methods: It can be sprayed with 1000 times of 40% dimethoate emulsion to kill or burn the old branches of shield shells.
