How to plant Dendrobium on trees

Now many people are planting Dendrobium, so how to plant Dendrobium on trees? The following is the method I compiled for you to plant Dendrobium on trees, I hope it will be useful to you.

methods of planting Dendrobium on trees

There are many kinds of Dendrobium species that can be planted. Generally, trees with rough bark and moss are easier to plant. Bark is smooth and can also be planted by creating conditions. Like Xishuangbanna, mango trees and banyan trees are very suitable.

If the trunk is small and the bark is smooth, we can choose a whole one to be wound around the trunk, and insert sawdust or bark into the gap between the stem and trunk of Dendrobium. 3? Water once every five days.

we can directly tie a small seedling with a root system to a branch with a rope, and when it grows a new root system, just drop the rope.

if we choose to plant it on the tree branches, we only need a stone to fix it and water it regularly.

If the surface of the bark is covered with moss, you can carefully dig a small hole in the moss, insert the stem of Dendrobium into the hole, and water it often. When it grows roots, it will naturally attach to the tree.

methods of planting Dendrobium at home

method 1:

propagation by dividing plants: select plants that grow more.

after flowering, take it out of the pot, remove the old roots and cut it from the base of the clustered stems.

take the main plants as a group and further cut off the old roots. Put the new bud near the center of the pot, fill in the new substrate and compact it, and you can grow into a new plant.

Method 2:

Cutting propagation: select the non-flowering and abundant ones to be used as seeding strips, cut the technical strips into several sections, each section has 2-3 nodes, and apply plant ash or mancozeb on the wound to treat the cut parts.

insert the stem into the mixed substrate of moss and peat one by one, with half exposed and placed in a semi-shady and humid place. You don't need to water it for 1 week after insertion, and then spray it regularly to moisturize it, so you can shade it properly.

after 1~2 months, new buds grow at the nodes, and 2~3 small roots grow at the lower part of the new buds to form new plants.

Put the new plant together with the old stem on it, and it will bloom after 2~3 years of cultivation.

Method 3:

Select Dendrobium which is robust and free from pests and diseases, cut off the old stems for more than 3 years for medicinal purposes, and use the new stems for reproduction at the age of 2 years. When breeding, the elder roots are subtracted, leaving 2-3 cm, and the seeds are separated, each plant contains 2-3 stems, and then cultivated in a greenhouse with decomposed soil in the mountains.

In the late stage of Dendrobium planting, if the air humidity is too low, it should be watered frequently and moisturized, and it can be sprayed with a sprayer. In the growing season of Dendrobium, attention should be paid to topdressing, and rotten peanut drums, rapeseed cakes and calcium superphosphate can be added to the mixture of river mud and sprinkled on the roots. In addition, .5? .1% potassium dihydrogen phosphate was applied as topdressing outside the roots, and the new high-fat film was sprayed to improve the utilization rate of effective nutrients, and Zhuangganling was sprayed at the right time during the growth period to make the plants stout and lush. At the same time, it can improve the ability to resist disasters, reduce the dosage of pesticides and fertilizers, and reduce the residual poison.

Before sprouting new shoots every spring, the withered stems in the cluster should be cut off in combination with harvesting old stems, and the diseased stems, weak stems and diseased roots should be removed, and then a new high-fat film should be sprayed to form a protective film to prevent replication and infection of germs. After planting for 6-8 years, it will be turned over and re-branched and propagated according to the growth situation of the shrew.

planting techniques of Dendrobium candidum

1. Environmental requirements for planting Dendrobium candidum. Protected cultivation? It is aimed at the small environment inside the cultivation facilities. Imitation of wild cultivation? It is aimed at the local climate environment, not the climate of the whole province or region. There are several main conditions as follows:

1. Temperature: survival temperature -2-41℃, growth temperature 1-35℃, and optimum growth temperature 2-32℃. < BR> In high temperature, such as summer, the greenhouse should be shaded and ventilated, and often sprayed to cool and moisturize; At low temperature, such as winter, it is necessary to keep warm and heat.

2. Humidity: Humidity needs to be adjusted according to the temperature. When growing vigorously, it is best to keep the air humidity in the small environment inside the plant at 6% ~ 9%. High temperature requires high humidity, low temperature requires low humidity, and ventilation should be strengthened to prevent bacterial and fungal diseases.

3. Substrate: Substrate is required for cultivation, and it is required to keep the root environment easy to leak, ventilate and have many gaps.

4. water quality: the water quality for pouring Dendrobium candidum requires weak acid or neutral water.

5. illumination: adjust shading with temperature and illumination, and control the shading degree at 5-8% when it is suitable for growth.

6. ventilation: the cultivation site requires good ventilation. Simply speaking, there are two major requirements: first, the requirements of the cultivation environment? Warm, moist and dim light? ; Second, what are the requirements for cultivation substrates? Is it loose, breathable and leaking? .

2. Artificial cultivation method of Dendrobium candidum:

The place or carrier for cultivation and planting can be flat land, hillside, wall, rock wall, trunk, balcony and flowerpot, which requires no water accumulation and easy drainage. When planting, you can first lay a 3-5 cm cultivation substrate, and then plant the cleaned seedlings on the substrate like seedlings. The substrate for cultivation can be selected: stones, limestone, bark, sawdust, waste materials of strains, etc., which are mixed according to a certain proportion; You can also choose sapropelic soil formed by leaves and branches under the forest and mix it with stones according to a certain proportion; Or part of crop shells are used as cultivation substrates.

III. Transplanting Dendrobium candidum

The natural reproduction rate of Dendrobium candidum is extremely low, and rapid mass propagation of Dendrobium candidum tissue culture seedlings through tissue culture has become an effective way to solve the seedling problem. Planting tissue culture seedlings of Dendrobium officinale on the elevated border can spray and water at any time, and drain away excess water at any time, which will not cause root rot and seedling death due to too much water, and can ensure the ventilation of the root system, so the survival rate of transplantation is greatly improved, which can reach more than 95%. .

1 preparation before transplanting

1.1 seedling hardening

Before transplanting, the bottle seedlings should be hardened in the seedling hardening room for 2-3 weeks, so that the bottle seedlings can transition from a closed and stable environment to an open and changing environment and gradually adapt to the natural environment, until the bottle seedlings grow vigorously, the leaf color is normal, the root length is more than 3cm, and the fleshy stem has 3-4 internodes and 4-5 leaves.

1.2 getting out of the bottle

when the tissue culture seedlings are taken out of the bottle, the bottle stopper is opened to gently take out the culture medium together with the seedlings, which are neatly placed in a basin to be cleaned, and the contaminated seedlings, bare-rooted seedlings or few-rooted seedlings are placed separately. Normal tissue culture seedlings should first wash the culture medium in tap water, especially the agar, so as to avoid the rotten roots caused by mildew of the agar, and then wash it in tap water again. After the above-mentioned cleaning, the roots of bare-rooted or few-rooted tissue culture seedlings need to be soaked in 1mg/L ABT rooting powder for 15 minutes for rooting induction. After cleaning the contaminated seedlings, soak the whole seedling with 1 times carbendazim for 1 minutes. Proper management in the later stage can effectively control the occurrence of pollution.

1.3 preparation of substrates

suitable substrates should be selected for transplanting Dendrobium candidum tissue culture seedlings. The roots of Dendrobium candidum are aerial roots, which have obvious aerobic and shallow roots. Therefore, it is appropriate to require the substrate to be loose and breathable, well drained, not easy to be moldy, and free from germs and pests. Weeds, limestone, broken bricks, bark, wood shavings, fern roots, board edges, fungus chaff and wood chaff can be selected as transplanting substrates.

IV. Field management of Dendrobium candidum

(1) Watering Dendrobium candidum should be watered frequently when the air humidity is too low in the later stage of planting, and it can be sprayed with a sprayer.

(2) Top dressing Dendrobium should pay attention to top dressing during the growing season. Rotten peanut drums, rapeseed cakes, calcium superphosphate, etc. can be added into river mud and sprinkled on the roots, and .5? .1% potassium dihydrogen phosphate was applied as topdressing outside the roots.

(3) before the whole branch shoots new buds every spring, the dead stems in the cluster should be cut off in combination with the old stems, and the diseased stems, weak stems and diseased roots should be removed. After planting for 6-8 years, it should be turned over and re-branched and propagated according to the growth of the cluster.

v. pest control of Dendrobium candidum

(l) Dendrobium black spot disease? Damage to leaves makes leaves wither, which occurs in March-May. Control method: spray 5% carbendazim l times for l-2 times.

(2) Dendrobium anthracnose? In order to damage leaves and stems, brown or gray lesions appear on the damaged leaves, which occur in L-May. Control method: spray 7% thiophanate methyl with 1 times solution for 2-3 times.

(3) Dendrobium candidum? Parasitic on the edge or back of plant leaves, sucking juice, the peak of incubation is in late May. Control method: The biological pesticide Haizhengmieling 4 times solution can be sprayed to kill or concentrate the old branches with shield shells and burn them.

VI. Harvesting and processing of Dendrobium candidum

(1) Harvesting is carried out at the end of spring every year before germination. When harvesting, the stems and branches that are more than three years old are cut off, leaving the tender stems to continue to grow.

(2) There are two methods for processing because of different varieties and commercial medicinal materials:

① Wash the collected stem plants completely, remove the leaves and fibrous roots, separate single stem plants, scald them in hot water at 85℃ for 1-2 minutes, take them out, spread them on bamboo mats or cement fields, and when the sun is 5% dry, rub off the sheath membrane by hand, then spread them in the sun.

② You can also soak the washed Dendrobium in boiling water for 5 minutes, take it out to dry, expose it to the sun on a bamboo mat, turn it 2-3 times a day, rub it while drying until it is soft, and repeat it many times until the residual leaf sheaths are removed, and then dry it until it is dry.
