The main fruit in autumn.

Coconut The main classification

Coconut coconut is divided into high and dwarf coconut, the tall coconut is the most widely cultivated in the world commodity of coconut. Tall coconut plant 15-30 meters high, base dilated, pollination, results in 7-8, high oil content, the economic life of 70-80 years. According to dwarf coconut fruit and leaf color is divided into red, green and yellow dwarf dwarf dwarf three. The plant only 5-15 meters high, self pollination, results in 3-4, the smaller and more fruit, meat thin, soft, and low oil content. The economic life of 30-40 years. The main fruits, parents and ornamental.

Coconut The origin of habitat

Coconut is native to South East Asia, Indonesia and the Pacific islands. Mainly distributed in Asia , Africa Latin America, between 23 DEG S-23 DEG N, the largest coastal area. The main producing areas of Philippines, India, Malaysia, Sri lanka. China southern islands and Guangdong Leizhou Peninsula , Hainan , Taiwan and Yunnan Cultivated tropical southern area,

Coconut Growth habit

 Coconut Coconut
Coconut in the annual average temperature is 26-27 DEG C, small temperature difference, the annual rainfall is 1300-2300 mm and uniform distribution, annual sunshine 2000 hours, an elevation of 50 meters below the coastal areas most suitable. Coconut is light tropical crops in high temperature and rainy, sunny and sea breeze under the condition of good growth and development. Coconut is suitable to grow in low altitude area, suitable for growth of coconut soil is marine alluvial soil and river alluvial soil, followed by sandy loam, clay gravel soil is again, the worst.

Coconut The mode of reproduction

Coconut Seed selection

In production by selecting excellent seed to harvest trees, improve the yield and quality of coconut.
The selected trees: high yield, spherical or hemispherical canopy, with 28-30 leaf above ear, 6-8 a coconut tree as the mother tree.
The selection of fruit in coconut mature season, fully mature, moderate size, near garden shaped fruits, namely "dense, heavy, ripe" selection method. "Secret" is shorter plants, leaves, fruit number, uniform distribution, "" that is a large proportion of the fruit, thin skin, high germination rate easily bred seedling, "cooked" is ripe fruit, shake a clear "Xiangshui" voice. Pick fruit after storage in ventilation, shade and dry place, 1 months after germination.

Coconut Grow seedlings

Coconut tree seed germination rate is not consistent, easy to cause the direct seeding of coconut garden seedling size uneven and lack of strain, so the best use of coconut seedling seedling. Seedling than direct seeding and labor, high survival rate, less waste of seeds, easy seedling selection.
The germination: in semi shade, ventilation, good drainage of the local site to remove weeds germination, roots, 15-20 cm deep. Then the excavation of germination ditch, germination groove width is slightly larger than the diameter of the fruit, dug a ditch after germination, the fruit of the hole ( Pedicel ) to, or 45 degrees oblique to the ditch, 1/2-1/3 wet sand to cover fruit, keep soil moist, after 60-80 days to germination.
 Coconut Coconut
The nursery nursery should be close to water, well drained sandy soil or Loam Deep plowing, 25-30 cm, border width can be 3-4, row distance of 40-45 cm, planting furrow depth of about 20 cm, width is slightly larger than the diameter of the fruit. Applying decomposed organic fertilizer and soil mixing, and sand termite. According to a distance of 30-40 cm to germination treated fruit oblique ditch, keep the seedlings vertical, buds in the same direction, covering over half of the fruit, that would have to be careful, be forced vibration of the fruit, grow seedlings, should be appropriate to add mulch, and well watered, nursery to strengthen the management, timely weeding, scarification, dry season should be watered regularly, but not the nursery water during the rainy season should pay attention to drainage, spring and summer with nitrogen fertilizer, can be applied to some dilute feces, autumn should be some potash fertilizer, enhance seedling adaptation, 1 years later, when Miao Musheng grows to about 1 m can Chupu planting.

Coconut cultivation techniques

Coconut Plant

Generally planted in the rainy season, according to the spacing of 6 m x 9 meters or 7 meters by 8 meters per hectare, planting 165-180 strain. The planting hole is 60 cm x 70 cm x 80 cm, cave in the organic fertilizer 20-40 kg, can also be burning leaves in the cave, cave and charred, fill sand ants, the sapling should bring fruit, much less soil, root damage, and to do with digging with the plant, planting depth of coconut seedlings on the base of rooting part can be buried in the soil is appropriate, "deep shallow earth", avoid dirt and leaves into the internal organs, appropriate rooted coconut tree growth than shallow planting, planting high yield than shallow, wind resistance than shallow and strong.

Coconut Administration

The nurse, after planting seedlings bumiao: to strengthen the management, after planting early due to shading, irrigation and moisture, lack of plant to timely replanting.
The tillage, soil and tillage intercropping: 2 times 1 years, which is combined with the fertilization 1 times in 11-12 months, 8-9 months and 1 times of cultivation, as the plants grow, the stem of a large number of gas minister rooting, Peitu, reinforcing the tree. The coconut garden can be as short-term crops, such as peanuts, beans and so on, to live coverage and improve the humidity effect, conducive to the growth of young trees.
 Coconut Coconut
The fertilization: coconut trees need to apply fertilizer to the whole. potassium Is the second largest fertilizer. nitrogen , phosphorus and chlorine Fat, but must pay attention to balanced fertilization. Coconut potassium, stems thin, short leaf, middle leaf canopy first wilting, leaf cluster downward extension, the lower part of the leaf withered and drooping hanging on the trunk; nitrogen deficiency, Leaf Chlorosis, less shiny, old leaves appeared different degree of chlorosis, the amount is reduced, copra production decreased; P will cause bad root and fruit rot; lack of chlorine will affect the size of coconut, copra production and utilization of water and nitrogen uptake and plant. Therefore, when fertilization to organic fertilizer, fertilizer supplement, and some salt. Every year in 4-5 months and 11-12 months without fertilization, fertilization ditch at the base of the tree distance of 1.5-2 meters, good effect. If the broadcast method should be comprehensive, weeding and loosening the soil after fertilization.

Coconut Pest control

Coconut spilled blood disease is a common disease in coconut. Symptoms: stem cracks, exudation of dark brown mucus, dry black, rotten tissue cracks. A control method of chiseling disease tissue, coated with 10% Bordeaux mixture or coal tar.
Red brown like larvae drill trunk, can make the coconut tree withered. The prevention of wound coating with asphalt or mud, severe deforestation burned to prevent spreading.
Coconut scale adults and nymphs on the back of leaf and fruit on the surface of sweat. Control of spraying ammonium parathion, malathion, Dibrom pesticides, also can protect the natural enemies to control.
Coconut rhinoceros, rhinoceros warts in two main hazards, leaves show fan-shaped open, or wavy toothed bite growth, make the plants withered, prevention before March of each year for removing organic coconut and compost, etc., dung breeding sites, rotting with cow dung or dry coconut to lure adults produced eggs concentrated hunting can also use predators such as Metarhizium Tufeng, rhinoceros larva control.
