When does the dragon fruit blossom and bear fruit? What is the annual net profit of planting 100 mu?

The dragon fruit is named because it looks like an angry red fireball. It has been planted in Hainan, Guangxi, Guangdong, Fujian, Yunnan and other provinces. So when will the dragon fruit blossom and bear fruit? What is the annual net profit of planting 100 mu?

What is the annual net profit of planting 100 mu of dragon fruit?

In general, the output value of the picking garden is 5000-7000 yuan per mu, but the early investment is relatively large. If there is a large area, then the land lease, management, farming and full employment labor costs are also large. It is estimated that the net profit is about 1500 yuan. What is the annual net profit of 100 mu of dragon fruit?

1500000 yuan = 150000, but this kind of thing market is sometimes very volatile

The dragon fruit began 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 in the 40th day after flowering, and the single fruit weighs 500g-1000g. It produces more than 20 fruits per column in the second year after planting, enters the full fruit period in the third year, and the higher management level can reach 2500kg/667m2 per unit yield.

1. Growth environment

Fire dragon fruit is a tropical and subtropical fruit, which likes light and shade, heat and drought, fertilizer and barren. Growing rapidly in a warm, humid and sunny environment, open field cultivation in spring and summer should be watered more to keep its roots in a state of exuberant growth, and should be drained in time in rainy weather so as not to cause stem and flesh rot caused by bacteria. The stem can also grow on the rock, and the plant is extremely resistant to wind, as long as the bracket is strong enough to resist typhoon.

2. Potted plants

The main results are as follows: (1) the germination temperature of dragon fruit seeds is about 25 ℃.

(2) the culture soil with fine particles should be selected, and the sowing soil sold in the market can also be used instead.

(3) the pulp and gum attached to the seed must be removed, otherwise it is easy to grow mold during germination.

(4) to make small potted plants, the seeds should be spread more closely, especially at the edge, otherwise they will lose their sense of beauty.

(5) if the basin does not have a bottom hole, do not use a kettle directly to avoid overwatering. Spray water with a spray can once every 2-3 days.

3. The main points of high-yield cultivation are as follows:

1. Frequent application of thin fertilizer: due to the long harvest period of fruit, organic fertilizer should be re-applied every year, and nitrogen, phosphorus and potassium compound fertilizer should be applied evenly for a long time. Potassium and magnesium fertilizers should be added during flowering and fruiting period to promote sugar accumulation and improve fruit quality. Keep the soil moist during the fruiting period, and the tree plate is covered with grass or mushroom residue. When the weather is dry, irrigate once every 3-4 days. Like other cactus plants, dragon fruit grows less than conventional fruit trees. Therefore, fertilization should be based on the principle of adequacy, small amount and multiple times.

2. Pick the heart: when the branch grows to 1.3-1.4 meters long, it promotes the branch and lets the branch droop naturally.

3. Interplanting and artificial pollination: when planting pitaya, it is necessary to plant about 10% of the white meat type of pitaya. Mutual pollination among varieties can significantly improve the seed setting rate. In case of overcast and rainy weather, artificial pollination should be carried out. Pollination can be used to apply pollen directly to the stigma of female flowers before the flowers bloom in the evening or before the flowers are closed in the morning.
