Areca nut is a tropical plant, growing in the tropical rainforest, warm-loving, moisture-loving, good fertilizer, and the optimal growth temperature of betel nut tree is between 25-28 degrees, poor cold resistance, the temperature is lower than 16 degrees will appear fruit drop, and below 5 degrees will suffer frost damage.

The betel nut tree is mainly cultivated by sowing, first the seeds are collected from the mother tree that has grown for more than 15 years, and then the seeds are dried for 2 days and then buried in the wet sand to promote germination, and the young shoots are planted after they grow to 3 cm, and the betel nut seedlings can be planted in fertile fields after they grow 5-6 leaves.

The areca nut tree is arbor-like, the plant height is between ten meters and thirty meters, the stem is erect, there are ring-shaped leaf marks on the bark, the leaves are lanceolate, the length is about thirty centimeters, when planting the betel nut tree, the seeds should be buried with wet sand, wait for them to germinate, and then plant the seeds in the soil, and provide nitrogen fertilizer for them in the breeding process to promote the growth of the betel nut tree.

1. Shape introduction

The areca nut tree is arbor-like, its stem grows straight, the height is generally about ten meters, the highest can grow to thirty meters, and the leaves of the areca nut tree are narrow and lanceolate, the width is about thirty centimeters, the color is green, the fruit is oval-shaped, and it matures in March and April every year.

2. Planting method

The planting of betel nut trees is mostly done by sowing seeds. In June each year, the golden seeds are harvested from the betel nut tree, dried for three days to remove the skin, and then buried in moist sandy soil, after which the seeds germinate, at which point they can be removed and planted in fertile, loose, sunny and ventilated fields.

3. Provide nutrients

The areca nut tree has a greater demand for nutrients in the process of growth, and the seedling stage can provide it with human and animal manure and well-rotted green manure to improve the growth rate of the plant, and the areca nut tree can provide it with phosphorus and potassium fertilizer and nitrogen fertilizer after adulthood, so as to promote the flower bud differentiation of the plant and bear fruit.

4. Disease prevention and control

The common diseases of betel nut trees are leaf spot disease and fruit rot, and the diseased plants will have dry and black leaves, green fruit rot and fall off, at this time, the diseased branches and leaves on the areca nut tree should be cut off and burned, and then diluted Bordeaux solution should be sprayed to destroy the pathogens.

The height of the areca nut tree is about 10 meters, the height can reach 30 meters, its leaves are clustered at the top of the trunk, the length can reach 2 meters, showing a narrow lanceolate, and the flowering and fruiting period of the areca nut tree is in March and April every year, its petals are approximately round, and it is alone at the base of the branch, while the fruit of the areca nut tree is ovoid and orange-yellow.

1. Shape introduction

The areca nut tree is an arbor plant of the palm family, its height can reach up to 30 meters, the trunk is erect and straight, there are obvious annular leaf marks, and the leaves of the areca nut tree are clustered at the top of the trunk, the shape is narrow and lanceolate, its flowering and fruiting period is in March and April every year, and the fruit diameter of the areca nut tree is about 4 cm.

2. Seed treatment

When propagating betel nut trees, it is necessary to collect fruits on the mother plant that is 15-30 years old and has a high yield, and the surface of the fruit is preferably golden yellow, and then the fruit of the betel nut tree is placed in the sun to dry for 1-2 days, and after it is dry, the fruit can be buried in the moist sandy soil for germination, so that the germination rate of the betel nut tree is improved.

3. Sowing and propagating

The best breeding time for betel nut trees is in February-March or August-October every year, because the temperature and humidity at this time are higher, which is conducive to improving the survival rate of betel nut trees.

If the betel nut tree grows well between the nodes, the nursery land of the betel nut tree should be close to the water source, with a certain shade of trees, fertile and loose, and well-drained sandy loam or loam soil, which should be furrowed after deep ploughing and fine raking. It is advisable to choose a place on the southern slope of a hill, a valley or a leeward place on both sides of the river bank below 300 meters from the sea. If the slope is larger, the land should be prepared according to the horizontal strip, the width is 3 meters, the belt is inclined inward, and a water storage ditch is dug on the inner side of the belt, the width of the ditch is 30 cm, and the depth is 25 30 cm.

After land preparation, dig a hole according to the plant row spacing of 2 3 meters, and the hole is 60 60 50 cm, to be planted. Choose to grow for 15 30 years, the thickness of the stem is consistent, the internodes are uniform, the flowering is early, the inflorescence is long and slightly drooping, and there are more than 3 inflorescences per year. The fruit is picked in May and June, and the disease-free fruit is selected to be oval or oval, the exocarp is golden yellow, smooth without marking-like cracks, uniform size, plump, hard kernel, heavy kernel, and about 18 22 less than 22 disease-free fruits per kilogram of fresh fruit for seeding.

Germination. After the fruit is picked, it should be exposed to the sun for 1 2 days to absorb heat and facilitate seed germination. Subsequently, germination treatment is carried out, and its method:

Stacking and germinating orange mold method: under the tree or ventilated room near the water source and shade, spread a layer of sand on the ground, pile the fruit into a small pile of 20 cm high, cover with straw, the thickness is not visible to the fruit, pour water 1 time a day, keep it moist, at a temperature of about 35, after 7 10 days, the exocarp begins to ferment and rot, open the straw in time, take out the fruit, wash it with water, and put it in the sun for 1 2 days. Then re-stack, cover the grass, and drench it with water, while taking care to prevent pests from causing damage.

18 After 28 days, the fruit pedicle should be peeled regularly every day for inspection, and if there are white bud spots, they can be taken out for seedling. Basket germination method: If the amount of seeds is not much, the fruit can be packed in the basket, sealed with straw, placed in the house for heat preservation, and drenched with water.

When the peel is fermented and rotten, the basket and the fruit are placed in running water to wash the peel clean, then re-basket and put it in the house, and when there are white bud spots, take out and sow seedlings. In addition, there is also the seedbed germination method, because of the large area and uneven seedling, the origin is rarely used.
