King Coconut


Section name: Palm Branch

Scientific name: Roystonearegia

Country of Origin: Cuba, Jamaica, Panama

form:

For the tall trees, up to 20 meters, diameter 30-40 cm, stems gray and white rings, the central often inflated. Leaf sheaths green, smooth, pinnately cracked, 3-4 meters long. The panicles are numerous and short branches, 40-60 cm long. Fruit ball. Famous tropical ornamental plants.

Growth characteristics:

Slow growth. Heat-resistant, cold-resistant, drought-tolerant, moisture-resistant, rubidium-resistant, wind-resistant, anti-pollution, old strains transplanted difficult, long life. Positive plants need strong light. Appropriate temperature 20 ~ 30 °C.

Landscape use:

The trunk is thick and tall, suitable for street trees, Tim King trees, Guangdong, Guangxi, Fujian, can be the garden, campus, parks, recreation areas, corridors, etc., can be single plant, planting, group planting landscaping.

Due to tall trees, single plants are more difficult to coordinate with other plants.

The king coconut tree is evergreen and its trunk is tall and magnificent. It is an ideal ornamental tree in southern gardens. It is widely used in squares, road dividers or riverside paths. It is one of the main tree species for the greening of southern cities. Now its fast-growing cultivation techniques are described as follows:

First, seed collection and sowing

The exocarp of Dawang Coconut changed from blue to reddish-brown to purple-black, and the seed endosperm was hard, indicating that the seed was mature and could be harvested. After the seeds are harvested, they should be soaked in water or with straw for about a week until the peels are soft and the pulp is washed away with water, which can then be stored with the sowing or sand storage (not suitable for exposure or dehydration). When sowing, the temperature should be above 20 °C, such as spring. After sowing pay attention to moisture and cover shed, keep the light transmittance 30-40 °C appropriate. According to the experimental records, from May to October sowing in the sand bed, the fastest 15 days can germinate, after 2 months the end of the basic germination. After sowing in November, germination continued one month later, and a small amount of seeds germinated in the second spring. It can be seen that seeding at different times and the duration of germination are inconsistent. King coconut seeds and mice like to eat, so after the broadcast need to cover the rodent to prevent loss.

Second, nursery

Dawang coconut is a shallow-rooted species of fibrous roots. It responds sensitively to moisture. When it moves from the sand bed to the alfalfa, it is often damaged by some root systems, weakening the water absorption function, and causing the leaves to yellow or die. The seeds of Dawang Coconut contain nutrient-rich endosperm, which can grow without relying on foreign nutrients for a period of time after germination, so it is easier to transplant at the initial stage of germination and rooting. In view of this situation, after 1 month of germination, when only 1-2 roots have been grown in the roots, rainy weather should be used to transplant the sand bed seedlings into the depression. In order to save land use and centralized management, our approach is to directly transplant sand-bed seedlings in nutrient bags for a year, keep the soil moist, and pour urea, water and fertilizer once every two months, with a concentration of 3-5%, and then select them in the spring of the second year. The rainy weather transplanted the seedlings into the depression. King coconut in the young age of sex hi Yin, so the summer should be placed in a shaded environment, the winter need to have straw or film covered with anti-frost winter. As long as the above points are achieved, the annual seedling height can reach 50-60 cm (natural height) and the ground diameter is 2-4 cm.

Third, cultivation and management

Planted land should be selected for deeper soil, well-drained, loose, fertile acidic or slightly acidic soil. The planting time should be considered from two aspects. First, King Coco Co., Ltd. prefers to be warm and tolerant and cold. The suitable temperature is 23-25°C. When the temperature drops below 15°C, it stops growing. The second is that Dawang coconut is a partial negative light plant. It is afraid of strong light at the seedling stage. It should be planted in the climate conditions from April to May and from August to October. At this time, the temperature is suitable and the survival rate after planting is higher. After transplanting, the water was thoroughly sprayed and the nursery soil was often kept moist during the growth and development of the seedlings. Planting density depends on the size of seedlings to be cultivated, generally 80 centimeters and 80 centimeters is appropriate, 700 acres can be planted. After the seedlings are alive, nitrogen fertilizer is applied once a month during the growing season, and can be applied dry (shallow ditch shallow application), but also Water facilities, after the addition of phosphorus and potassium fertilizers after September. Weeds can be sprayed with herbicides, the concentration of which depends on the type of weeds and herbicides, and the general amount of glyphosate 0.5-0.7 two / 30 catties of water, spraying twice a year can be. As long as the water and fertilizer management is strengthened, after 5 years of cultivation, the natural height can reach 4.5-5.5 meters, the pole height 1.8-2.0 meters, and the 1-meter rod diameter can reach 40-60 centimeters, namely the standard seedlings for landscaping.
