Technique of planting

I- DAI CUONG: 
 
* Do Bau Huong (Do Tram) is the preeminent type in the Do Bau group, planted to get Agarwood. That is an important source of medicinal herbs and aromatherapy, with high economic export value, and favored in the world market.
* In Oriental medicine, Tram Huong is a precious medicine (spicy, slightly temperate), goes into the economic channels, tastes, and kidneys, has the effect of recharging the kidneys, balm and gums. It also cures chest pain, abdominal pain, vomiting, asthma, urinary retention and stomach tonic.
* Currently, Japan is studying to use Tram Huong to treat a number of incurable diseases.
* In addition, Tram Huong is also used to make high-class perfumes and shampoos. Agarwood for precious interior decoration etc.
* Do Tram also contributes to environmental improvement by purifying polluted air, inhibiting the growth of bacteria and viruses that cause disease. La Do also has the effect of curing many diseases, so planting the Do Tram is a valuable medicine in our house.

II - PETROLEUM PLANTING TECHNIQUES:

Vietnam is a country favored by nature, the climate is very suitable for planting Agarwood.

So Tram lives on many types of soil: preferably red basalt soil, except for waterlogged soils, alum-contaminated, or on limestone.

Vegetation status is suitable for farmland, poor forest, forest after shifting cultivation or household gardens.

Do Bau Huong seedlings of Do Bau Huong Company are grown from seeds. Standard plants are 8-12 months old, over 40 cm high, the root collar diameter is over 0.35 cm and are free of pests and diseases. Seeds are obtained from mother plants> 12 years old, and grown in a potting medium according to traditional methods. Seeds lose their ability to germinate very quickly (1 week), so when taking seeds, seedlings must be planted immediately.

1- Time of planting: Best in the beginning of the rainy season.

2- Planting method: Depending on the type of soil, the type of vegetation.
+ Planting in monoculture:
- If planted on farmland or forest land after shifting cultivation, according to specifications of equilateral clusters: trees are 1,2-1,5 m from trees; phrase distance 2-4m. Density 1,600-2,000 trees / 1 ha.
- If planted on poor forest land: 2m from the tree, 10-12.5 m from the row. Planting density ranges from 400-500 trees / ha.
+ Intercropping:
Very suitable because the tree is resistant to shade, grows fast when living with other trees. Therefore, in the plant structure change, we do not have to cut down existing trees but alternate the garden of pepper, cashew, coffee, tea, amomum, fruit trees or short-term fruits such as pineapple (pineapple). , legumes, corn, melons, chili etc. Get available benefits to raise Dó trees (of saving money). Rubber trees should not be planted together with Dó bass because it grows fast and has a large canopy.
It is recommended to plant in clusters of equilateral triangles, trees 1.2-1.5m from trees, 2-3m clusters from clusters, rows 2-4m from rows.
Benefits: Planting in triangular clusters minimizes the cost of drilling and cultivating later (one rig, drilling all three trees). When the plant was planted with the catalyst, due to many injuries, strong winds could easily break the tree. We can brace a cluster of three trees: tops with tops - roots with root together into a block to protect the tree.

VEGETABLE PLANT:

3- Planting method:
* Vegetation treatment:
a / For poor forest soils:
Before planting, it is necessary to treat the vegetations according to the cutting tape, the width of the cut band is equal to 1 / 3 - 1/2 of the average height of the forest. It is necessary to treat all vegetations tightly, with stump not exceeding 15 cm high, chopped, stowed, then dig planting holes on tight ice, with a row of trees each.

b / For forest land types after shifting cultivation:
* Comprehensive vegetation treatment, chopped, cleaned and then dug planting holes in rows.
* Digging hole: size 40x40x40 cm. Mix 1/2 soil + 1/2 with rice husk ash to make soil porous, then place plants and fill the hole. You may not apply primer first, until the roots of the plant will slowly seep the fertilizer.
* If you want to fertilize, it is best to use compost or manure (cow and buffalo manure). Use decomposed manure (14% manure + 1% super phosphate).
* When digging, put the topsoil aside. Digging must be completed 1 month before planting. Use the topsoil to mix well with manure to fill the hole. The completed hole must be 2-3 cm above the natural ground. Fertilizing, filling holes, must be completed 10-14 days before planting.
* This is a forest tree, it should not be used much fertilizer. High nitrogen makes plants susceptible to disease and death. Do not use pig manure. Chicken manure is good but hot and only fertilized when plants are> 2 years old.

c / For household gardens:
* Treat around the stump with a diameter of 1-2 m for trees in the household gardens, not affecting Do Bau trees.

4-Planting techniques:
During transport, the plant can be rooted. When receiving seedlings from home gardens should be kept in a shade place to monitor and care for a while (1-2 weeks) for good before planting. Practice slowly getting used to the sun and wind. Do not water the plants for a few days for dry, hard pots to plant, then water the plants after planting. Selecting strong-growing plants to plant first, plants that appear weak, need to be planted for a while. If the tree is deciduous, let it sit for a while, use foliar fertilizer to spray (according to the instructions on the fertilizer bottle) for the tree to take root and return leaves. When the stump dies completely, scrape off the bark of the stump, no longer see the green color, but only see a dry yellow color that the tree really dies. Choose days with small continuous rain, cool weather, and no wind to plant. Be careful, light-handed, skillful not to break the potting medium because the dead plant in the pot will be high. According to past experience,
- Stage 1: Use a sharp knife or sharp pull to cut around the nylon part at the bottom of the pot and discard it, while the upper part of the soil ball still keeps the plastic wrap (to minimize the breakdown of seedlings, broken roots). Using a hoe, open the hole wide enough to place the pot, the depth is 1-2 cm higher than the height of the pot. Then place the tree neatly, the stem straight, the pot leaning against a pit wall, cover with soil and compact tightly (keep the neat plastic wrap around the seedling pots). Build the soil around the base of the tree 4-5 cm above the natural ground. Do not plant in the middle of the hole to avoid root collapse.
- Phase 2: for a period of about a month for the tree to slowly get used to the new soil environment and when the roots are stable, we will gently dig the stump, use a knife to cut straight down into a plastic bag containing the soil. Previously, the children left behind and took away plastic bags to completely free up soil for the roots to grow freely.

* THINGS TO REMEMBER WHEN PLANTING THE FLOWER VEGETABLES:

- When first planted, the tree should be tied to the pile to avoid shaking the roots in strong winds.
- Trees like shade. If planted alone, the seedlings can be shaded with coconut leaves. Cut coconut leaves into 2, 3 and then shield the afternoon sun direction on hot days in the first year.
- The most common cause of plant death is potting medium, broken roots or water retention, increasing moisture in the soil. Therefore, watering should be sprayed with mist, not soaking the pots or stumps frequently.
- When plants are yellowed, check soil moisture. If soil moisture increases, plants are susceptible to fungal infections (use Anvil or other antifungal agents in the roots according to the instructions on the medicine bottle).
Do tree has strong vitality, if the tree is disturbed by its roots, deciduous, and its branches are inert, it is not necessarily dead, we should still take care of it, the tree will sprout new branches. Only after 1 month of taking care that the tree does not produce leaves will it be considered that the tree is really dead.
- In the rainy season, you should cultivate the stump slightly higher than the ground, clear puddles near the base of the tree, dig ditches, ditches for drainage to avoid stagnation of water at the base to increase soil moisture, flooded roots, trees are susceptible to died.
- In hot season, a few days should water enough for the fast growing plants. Do not scour the tree to make the roots protrude, the tree will be damaged.
- Do not plant trees at the beginning of the dry season because the hot sun, lack of water can prevent the tree from living.

III- PLANT CARE:

1- Care regime:
Newly planted plants need to be cared for according to the following regimes:
- Year 1: Take care 1-2 times.
Year 2 to 3: Take care 2 times a year.
From the 4th year until the forest closes its canopy: Once a year.
2- Care techniques:
- Repotting the dead seedlings in the first care of the first year or the following year. Choose a tree that grows well, with the same size as the planted one. Furrows spread vines, shrubs and weeds in the orchard.
- Shovel around the base of the tree to form a circle, 0.8 to 1m in diameter
for the care times from year 1 to year 3.
-Post up 50 g of NPK fertilizer (component 2 nitrogen, 1 phosphate, 1 potassium)
within the tumbled circle. Each year, apply fertilizer 1 time in the first 3 years.
- For the method of planting according to the band and canal, it is necessary to prune the branches and cut the trees in the band to adjust the canopy so that in the 4th year, the trees are fully exposed to light.
Be careful not to use herbicides, insecticides, or other chemicals when you are disturbed, as broken roots can absorb chemicals and kill the plant.
- If using herbicides, spray on the grass, away from the tree base.

IV- PROTECTION OF VEGETABLE FORESTS:
1.
Pests and diseases prevention: - Leaf-eating pests often appear destructive from April to August every year. The method of eradication is to use a solution of Trebon with the dose of 1.5-2 ml of the drug in 1 liter of water and then spray the trees or raise weaver ants in the Do Depth forest.
- According to folk experience, it is possible to kill Dó leaves by using camphor hanging from a tree branch or crushing it with coconut oil and spraying it on the leaves.

2. Forest fire prevention:
Thoroughly prevent forest fires. In places prone to fires, there must be a fire barrier. It is forbidden to cook and sting bees in Dó forest. Do not let people and animals enter the forest.

CONCLUSION:

In short, the Do Bau Huong tree is easy to grow and live. It is a forest tree so it does not need to be applied much fertilizer. How to take care of only 1/2 to 1/3 of fruit trees. In the dry season in the first 2-3 years, the plants should be watered. Excessive drought or inundation of the roots both causes the seedling to die. Need to prevent forest fire. With the intercropping method, it does not take much effort (a couple of jobs), and returns great profits later.

Planting Do Bau Huong tree to create agarwood is a new breakthrough in the field of plants, is a great direction today.
