How to plant coconut trees? Coconut tree planting technology sharing!

Coconut tree refers to coconut tree, which is a kind of tree plant. In our country, coconut tree is mainly distributed in Hainan, and coconut tree is a unique local scenery in Hainan, which has good ornamental value. In addition to watching the coconut on the coconut tree, the coconut is also an organic fruit, containing a lot of nutrients that are beneficial to the human body. So what are such valuable coconut planting techniques? Please see the decomposition below.

1. Propagation techniques of coconut trees

Seed reproduction:

Fully mature coconuts begin to sprout in more than two months as long as they have proper warm and humid conditions. The method of sprouting in preparation nursery is widely used in Hainan. Choose a semi-shaded, well-ventilated and well-drained environment to remove weed roots, ploughing 15ml 20cm deep, trenching, and slightly wider than the fruit.

Plant the fruit one after another at an angle of 45 °against the bottom of the ditch and bury the soil to 1/2 to 2/3 of the fruit. When the buds grow 10m / 15cm, plant coconuts in a moderately shaded nursery, paying attention to watering, drainage, weeding and fertilization. In general, about a year, the seedling height of about 1 meter can be planted out of the nursery.

Mesoembryonic reproduction:

The embryo culture test-tube plantlets of Hainan high-variety coconut were used as transplanting materials. The results show that the key to the survival of coconut embryo culture seedlings lies in the quality of embryo culture seedlings, and the survival rate of embryo culture seedlings with developed root system and strong growth is high. The transplanting survival rates of normal seedlings, few root seedlings and contaminated seedlings were 86.7%, 29.5% and 36.4%, respectively. The ideal transplanting medium was peat: coconut bran: river sand = 2:1:1, and the transplanting effect was the best in the culture room.

II. Planting techniques of coconut trees

1. Timely planting:

Coconut trees are generally planted in the rainy season, with a row spacing of 6 meters × 9 meters or 7 meters × 8 meters, planting 180 plants per hectare, planting holes of 60 cm × 70 cm × 80 cm, and applying organic fertilizer 20-40 kg in the hole. it can also burn leaves in the hole, scorch the edge of the hole, and fill in sand to prevent ants. when starting seedlings, they should bring fruit seeds, bring more soil and less root injury, and do as they dig. The planting depth of coconut seedlings is that the rooting part of the base of the coconut seedlings can all be buried in the soil, so that the "deep planting and shallow cultivation of soil" should be achieved, and the soil should not be scattered into the leaf viscera. The growth of coconut trees planted properly is better than that of shallow planting, and the yield is higher than that of shallow planting. Wind resistance is also stronger than shallow planting.

2. Protect seedlings and cultivate soil:

The management of coconut trees should be strengthened after planting, the initial stage after planting should be properly shaded, irrigated and moisturized, and the missing plants should be replanted in time. The coconut tree is cultivated twice a year, that is, the coconut tree is cultivated twice a year, that is, the coconut tree is cultivated twice a year, that is, the coconut tree is cultivated twice a year, that is, the coconut tree is cultivated twice a year, that is, the coconut tree is cultivated twice a year, that is, the coconut tree is cultivated twice a year, that is, the coconut tree is cultivated twice a year, that is, the coconut tree is tilled twice a year, that is, once combined with fertilization from November to December, and once again from August to September. The coconut garden can be intercropped with short-term crops, such as peanuts and beans, which can cover the garden and improve the humidity in the garden, which is beneficial to the growth of young trees.

3. Rational fertilization:

Coconut trees need to apply total fertilizer, potassium fertilizer is the most, followed by nitrogen, phosphorus and chlorine fertilizer, but attention must be paid to balanced fertilization. When the coconut is deficient in potassium, the stem is thin, the leaves are short and small, the leaves in the middle of the crown wilt first, the upper leaves extend downward, and the lower leaves are dry and drooping in the trunk. Under nitrogen deficiency, the young leaves lost green and luster, and the old leaves yellowed to varying degrees, resulting in a decrease in the amount of dried coconut meat and the yield of dried coconut meat. Phosphorus deficiency can cause poor root development and fruit rot. Chlorine deficiency will affect the size of coconut, the yield of dried coconut, nitrogen uptake and water use of plants. Therefore, fertilization should be based on organic fertilizer, supplemented by chemical fertilizer, and some salt should be applied. Fertilizer can be applied from April to May and from November to December every year, and a fertilization ditch can be opened at a distance of 5m from the base of the tree, and the effect is better. If the sprinkling method is used, the weeds should be removed completely and the soil should be loosened before fertilization.

4. Disease and pest control

① diarrhea disease: coconut diarrhea disease is a common disease in coconut producing areas. When it occurs, the stem cracks, exudates dark brown mucus, is black after drying, and the crack tissue is rotten. Prevention and treatment methods include chiseling off the diseased tissue and applying 10% Bordeaux solution or coal tar.

② red brown elephant: red brown elephant larvae drill stem trunk, can make coconut trees die, control in the wound with tar or mud coating, serious felling and burning, so as not to spread.

③ coconut garden scale: adults and nymphs of coconut garden scale absorb sweat on the back of leaves and fruit, spray pesticides such as ammonium parathion, marathon and dibromophos during control, and protect natural enemies for control.

④ coconut rhinoceros: the harm of coconut rhinoceros is the most serious with two verrucous rhinoceros, the leaves are fan-shaped, or wavy engraved, bite the growth point, make the plant die, control for the removal of organic matter inside and outside the coconut garden before March every year, compost, dung piles and other breeding places, with cow dung or rotten coconut stem to attract adults to lay eggs and concentrate on killing, but also the use of natural enemies such as soil bees, Metarhizium anisopliae and other control rhinoceros larvae.
