The average annual purchase price of pitaya is: red pitaya 5-6 yuan/kg, white pitaya 3-4 yuan/kg. Based on the output of red pitaya of 3,000-4,000 kg/mu and 4,000-5,000 kg/mu, the annual income of white pitaya can reach1.2-20,000 yuan/mu, and that of red pitaya can reach1.5-24,000 yuan/mu.

The English name of Pitaya is pitaya, and its real names are Qinglong fruit and Honglongguo. The content of anthocyanin in pitaya is high. Anthocyanin is an effective antioxidant, which has antioxidant, anti-free radical and anti-aging effects, and also has the functions of inhibiting brain cell degeneration and preventing dementia. Pitaya is rich in plant albumin, which is not common in fruits and vegetables. This kind of active albumin will automatically combine with heavy metal ions in the human body and be excreted through the excretory system, thus playing the role of detoxification. Sesame in pitaya can promote gastrointestinal digestion. In addition, albumin can protect the stomach wall, and the planting benefit of pitaya has maintained a high level in recent years.

First, the selection skills of pitaya planting seeds

Seed selection of pitaya can be selected from mature pitaya. The specific selection method is introduced in detail online, so I won't go into details here. Need to be reminded that the pulp and gum attached to the seeds must be cleaned up, otherwise it is easy to breed mold when sprouting. When raising seedlings, if the culture soil with fine particles is selected, the germination rate will be higher, and the optimal germination temperature of pitaya seeds is about 25 degrees, so as to ensure the environmental temperature as much as possible.

Second, the fertilization principle of pitaya planting

The root system distribution of red dragon fruit is shallow, so it is appropriate to apply fertilizer in stages. After the seedlings germinate, apply 1 diluted human excrement and urine every 20 days, or apply150g chlorine-free compound fertilizer to each column, and then pour enough water or irrigation. Generally 1 year 10 times, 1 1 month 1 time to decompose pig manure and phosphorus powder, 20kg per column. In winter, covering with organic fertilizer 1 time, such as mushroom residue or bagasse, is beneficial to loosen the soil, and each column is 25 kg, which enhances the heat preservation and cold resistance of plants.

In the second year, magnesium sulfate and zinc sulfate were applied before flowering, and root fertilizer, 500 times super sweet essence, 500 times magnesium sulfate and 500 times potassium dihydrogen phosphate were sprayed every 15 days/time. Combined with soil, compound fertilizer 1 time per month, each time 150g. After picking fruits all year round, apply 20kg of decomposed pig manure to each column, add 0.5kg of phosphorus powder, or add 0.5kg of phosphorus powder to 2.5kg of bean cake, and then cover with mushroom soil or bagasse, with 25kg per column.

Third, the watering principle of pitaya planting

It is also important to use organic fertilizer when sowing. It is necessary to water, irrigate and nourish the pitaya tree every day after planting it. According to the wet area and 1 ~ 1.5 meters, the tree sprinkler is suitable for the back of plants and needs 80 liters of water every day. Avoid excessive water pressure, because it will lead to fruit cracking, falling flowers, yellow leaves and other plants and plant growth slowdown. It is also important to cover the surrounding plants regularly. Yes
