Where is the origin of the red dragon fruit, a vine plant? When will you plant and harvest? How many years do you want to bear fruit? What are the technologies?

Red dragon fruit is a perennial vine plant of the genus Cactaceae, which is a new fruit with good health care effect. Where is the origin of the red dragon fruit? When will you plant and harvest? How many years do you want to bear fruit? What are the technologies? It is learned from Hainan Red Heart Dragon Fruit planting Base that it begins to blossom and bear fruit 14 months after planting, and it can blossom 15 times a year. April to November is the fruit-bearing period. The fruit is ripe 30 days after Xie flower, and the weight of single fruit is 500-1000g. It produces more than 20 fruits per column in the second year after planting, and enters the full fruit period in the third year. If the management level is high, the per unit yield can reach 2500kg/667m2.

Where is the origin of Red Dragon Fruit?

1. Dragon fruit is a plant of the genus Cactus, also known as red dragon fruit and auspicious fruit. Originated in Central and South America, Costa rica, Panama, Ecuador, Cuba, Colombia and other places, Southeast Asia, Vietnam and other places also produce dragon fruit, dragon fruit set "fruit", "flowers", "vegetables" as one, can be said to be priceless.

2. In China, only some provinces and regions such as Taiwan, Hainan, Guangxi, Guangdong and Fujian grow.

When will the red dragon fruit be planted and harvested?

Planting:

1. The red flesh dragon fruit is a tropical and subtropical plant with bright color and rich nutrition, which contains glucose, vitamin C and a variety of minerals, has nutrition and health care functions, and can prevent constipation, skin care and beauty care, reduce blood sugar and blood lipids and so on. Flowers are edible and sun-dried is a good soup.

2. Red dragon fruit can be planted all the year round, and the suitable temperature is 20-30 degrees.

Harvest:

1. Dragon fruit, from May to November, there are not only one or two concentrated flowering and fruiting periods, but also scattered and multiple batches of flowering and fruiting periods, coupled with proper refrigeration and processing, so that tourists can taste delicious foods and drinks such as fresh fruit and pulp ice cream within half a year.

2. After one year of planting, the dragon fruit will have a yield of 1,000 kilograms per mu; after two years, it will be two or three thousand kilograms, and three or five thousand kilograms after three years. It is suitable to maintain the density of 6-7 000 drooping vines per mu, that is, about 10 / m2, with an average of 1 fruit per year, with an average fruit weight of 0.3-0.4kg and a yield of 2000-2670 kg per mu.

What are the planting techniques of red dragon fruit?

The trailing characteristics of red dragon fruit must be supported to facilitate growth, flowering and fruiting, and management of harvest. The bracket should be strong, resistant to heavy pressure and wind, resistant to soil corrosion, and cost should be considered. According to practice, there are three kinds of brackets to choose from.

1. Freestanding bracket of reinforced concrete column. The square reinforced concrete column is 2 m long, 11-12cm square in thickness, 0.5 m in soil and 1.5 m above ground. There is a 6-7cm steel bar protruding at the top to weld a steel cross disk with a column as the center and a diameter of about 0.7m. The column spacing is 3m (row spacing) × 2-2.5m (plant spacing), about 111-89 columns / mu. One seedling was planted on each side of the column, rooted by air and tied artificially, the stem climbed to the top of the column, and then stretched out on the iron ring to spread and droop around, and only the drooping branches were easy to bud and blossom. The outer tire of the old tire can be added to the iron ring to avoid excessive temperature or easy to break. Cement column strength is good, independent ventilation and light transmission is good, but must be buried really, drooping stem vines distributed evenly around (artificial assistance), so as not to tilt.

2. Rectangular row bracket for galvanized iron pipe. Row after row of piles are piled according to the row spacing of 3m. The thickness, fastness and decay resistance of the piles are based on the principle of maintaining dragon fruit climbing growth for at least one year. The column spacing is 1 m and the height is 1.2-1.4 m. Two fruit seedlings are planted next to it. After planting, set up durable galvanized iron pipe (tap pipe) bracket in a planned way, using 2.5cm pipe with outer diameter. With the wooden pile as the center, the frame feet are set at 0.5m on each side, that is, the frame width is 1m. Either the pipe or the 7-8cm square cement column (with steel bar) can be used as the frame foot, which will be more durable. The buried depth is firm, and the buried pipe should have concrete pier foundation. The height of the aboveground part is still 1.5m, the foot distance is 2-2.5m (depending on the strength of the pipe and the prosperity of plant growth), and the pipe is welded horizontally and longitudinally between the top of the foot. Within a year of planting, when the stem of the seedling is tall and branched, it is necessary to manually guide the stem vine to both sides of the pipe frame from time to time, so that the row support is under heavy pressure. Row-type stent planting is easier to manage, and the per unit yield is higher. Jinkui subsidiary is mainly planted in this way, followed by column support. Row planting should be planned in a north-south direction so that both sides receive light evenly.

3. Cross steel bar group bracket. Dr. Wang Qunguang in Taiwan has abandoned medicine to grow dragon fruit from agriculture for many years of practical experience, and believes that this kind of stent is the most ideal. The method is to use bamboo steel bar with 5 points thick (1.7cm), which is cut and grown by 2m and 3.2m. The former is used as the frame foot, the two steel bars are knocked into the soil at an oblique angle of 0.5m, the upper part crosses each other, and the distance between the cross tripods is 3m. Fasten the intersection (including the transverse steel bar) with a stainless steel wire or cable clip, and add a steel bar (or pipe) vertically in the middle of the transverse steel bar to withstand the later heavy pressure. The planting of fruit seedlings and temporary stakes are the same as the second way, when the stem is tall, the stem is placed on the transverse steel bar.

4. Others. For non-large-scale cultivation, dragon fruit can also be attached to low walls, living tree stumps, and even rely on tree trunks without branches and leaves in the lower part, such as betel nut. But can not use scaffolding cultivation, because the horizontal extension of the stem vine, more branches and less bud blossom, even if the fruit is difficult to harvest. It is difficult to cut the branches of the roof, and it is dark under the shed, which is disadvantageous to blossom and bear fruit.

The dragon fruit is a long-lived plant that has survived for decades or even hundreds of years. Therefore, no matter what kind of support is used, its firmness and durability should be put in the first place. It should also be considered that after a few years, if the support is overloaded, it can be strengthened more conveniently without affecting the normal growth of the year under the premise of proper thinning and cutting. According to our several years of planting experience, we should also pay attention to the fact that when building a new garden, the row spacing should not be small, with a minimum of 2.5m, otherwise the stems will be fully extended, and the narrow passageway will make managers and tourists avoid the sharp short thorns on the triangular stem everywhere. Very uncomfortable and convenient.
