Question 2: What are the places where dragon fruit is suitable for planting Dragon fruit distribution
Originally from Central America, Costa Rica, Guatemala, Panama, Ecuador, Cuba, Colombia and other places. Later introduced into Vietnam, Thailand and other Southeast Asian countries and China's Taiwan Province, Hainan, Guangxi, Guangdong, Fujian, Yunnan and other provinces and regions of mainland China.
Dragon fruit is a tropical, subtropical fruit, light and shade, heat and drought, fertilizer and barren. Nursery beds should be selected ventilation to the sun, fertile soil, convenient drainage and irrigation of the field. In the warm and humid, light-rich environment of rapid growth, spring and summer open field cultivation should be more watering, so that its root system to maintain the state of vigorous growth, in the rainy weather should be timely drainage, so as to avoid infection with pathogens caused by stem rot. Its stem can also grow on the rock, the plant is very strong wind resistance, as long as the bracket is solid can be resistant to typhoons. Dragon fruit is resistant to 0 ℃ low temperature and 40 ℃ high temperature, the optimal temperature for the growth of 25-35 ℃. Dragon fruit can be adapted to a variety of soils, but with more humus, water and fertilizer neutral soil and weakly acidic soil is good.
Question 3: Where is the dragon fruit suitable for planting dragon fruit can be planted all year round, pay attention to not deep planting, implantation of about 3cm deep can be, the initial period should keep the soil moist.
In the spring is the most suitable, plugs selected growth full of stem nodes, cut off the length of 15 cm of small segments, to be wound air-drying inserted into the sand bed, about 15-30 days can be rooted, the root grows to 3-4 centimeters when the transplantation of the seedbed.
12-14 months after planting to start flowering and fruiting, can flower 12-15 times a year, dragon fruit fruit plate
April to November for the fruiting period, 30-40 days after the flower is ripe fruit phagocytosis, a single fruit weighs 500-1000g, the second year after planting, every year, every year, every year, every year, every year, every year, every year, every year, every year, every year, every year, every year.
Problem four: dragon fruit in China what place to plant more Guangxi it
Problem five: dragon fruit in what place to grow dragon fruit [Hylocereus undatus (Haw.)

Dragon fruit development potential 1, dragon fruit cultivation advantage dragon fruit for tropical, subtropical fruit, its cultivation technology is simple. Sex like warm and humid, shade tolerant and barren, the optimal temperature for the growth of 25 ~ 35 ℃, but the annual minimum temperature is higher than 5 ℃ can be planted in the open air. The soil requirements are not strict, flat land, paddy fields, slopes or dry land can be cultivated, in fertile, well-drained neutral or slightly acidic sandy red soil or loamy soil grows well, with aerial roots, roots more strong, vitality and its exuberance. Propagation methods mainly use cuttings and grafting ...... >>
Question 6: Where is the most suitable place to grow dragon fruit in China Dragon fruit belongs to the tropical and subtropical fruits, drought-resistant, heat-resistant, light-loving, the soil requirements are not strict, flat, hillside, sand and gravel can be planted, the optimal soil pH value of 6-7.5, it is best to choose the organic matter rich and well-drained land planting. Dragon fruit is not frost-resistant, winter temperatures below 0 ℃ area using simple greenhouse planting.
According to the habits of dragon fruit, in China south of the Yangtze River are suitable for planting, such as planting in the north to pay attention to winter warmth.
Hope to adopt, thank you
Question 7: When is the best time to plant dragon fruit, the most suitable for planting where dragon fruit can withstand low temperatures of 0 degrees Celsius and high temperatures of 40 degrees Celsius, the growth of the optimal temperature of 25 ~ 35 ℃, but the annual minimum temperature is higher than 5 ℃ of the place can be planted in the open air. But in order to ensure its perennial growth and multiple results, try to reach the appropriate temperature of 20-30 degrees Celsius, in the northern planting of dragon fruit must build greenhouses, winter night temperature is not less than 8 degrees Celsius. Summer may not remove the plastic film, but must be ventilated.
Dragon fruit can be planted all year round, to plant as early as possible and planting after planting dragon fruit has sufficient growth and recovery time, farming help suggests that transplanting during this period of time from March to November is the best.

Seedling
Dragon fruit is mainly propagated by cuttings or grafting.
1, cuttings: the most appropriate in the spring, the cuttings selected full-grown stem nodes, cut off the long 15 cm section, to be inserted into the sand bed after the wound air-drying, about 15-30 days can be rooted, the root grows to 3-4 centimeters when transplanted to the seedbed.
2, grafted seedlings: choose no pests and diseases, robust growth, stem flesh full of measuring tape as rootstock, grafting in sunny days. Dragon fruit stems with a knife cut plane, the scion inserted, aligned with the formation layer, tied with cotton thread fixed, in 28-30 ℃ conditions, 4-5 days wound joining surface that is a large number of healing tissue formation, scion and rootstock color close to the two vascular bundles have been healed, grafting success, and then can be moved into the false planting seedbed to continue to cultivate.
3, seedling management: nursery beds should be selected ventilation to the sun, fertile soil, drainage and irrigation of the field, the whole fine for the bed, bed with grooves 90 cm, 667 square meters of rotted chicken manure or cow dung 1500 kg -2000 kg, mixed with 1000 kg of husk ash, stirred well, in the preparation of the ground when the application of the bed below 10-20 cm of the topsoil layer. Then apply 100-150 kg of calcium-magnesium phosphorus fertilizer, mix it well with hoe, and apply it in the topsoil layer of 4-5 cm depth, then plant the seedlings in the seedbed at 3 cm distance between rows and plants, water thoroughly, and spray 500 times carbendazim once, and apply 5 kg-15 days of carbendazim every 10-15 days, and spray 500 times carbendazim every 10-15 days. -15 days to apply 5 kg -7 kg of compound fertilizer, and so long as the growth of the first section of the stem flesh full of stem segments, can be out of the nursery.
