The planting technology of cactus family dragon fruit is collected quickly!

Pitaya is a perennial succulent vine plant belonging to Triangulum of Cactus Family. It is one of the characteristic fruits developed in Guangxi. At present, the cultivated area is expanding continuously and has become one of the "landmark fruits" in Guangxi. Today, I will introduce the planting technology of pitaya to you and collect it quickly!

1. Dragon fruit types and basic characteristics

1. Common varieties

Pitaya can be divided into red skin white meat, red skin red meat species or red skin purple meat species, yellow skin white meat three categories, the main species planted in production are red skin white meat and red skin red meat species, among which red skin white meat species is the most common variety, larger, low sweetness, cool and refreshing; Red skin red meat is also more common, less expensive cultivation, higher sweetness; Yellow skin white meat market called Kirin fruit, relatively rare, small fruit, large seeds, sweet but no fishy smell, the highest sweetness.

2. Basic characteristics

① Pitaya suitable growth temperature is 25-35℃, 5 ℃ below will cause serious damage, so in the lowest temperature below 10℃ area requires plastic film cultivation;

(2) The soil permeability of pitaya planting is good, and the over-viscous soil can lead to poor root growth. The best soil water holding capacity is 60%-80%.

③ Soil pH requirements neutral or slightly acidic (PH6.0-7.5) is good.

Second, the cultivation technology of pitaya

1. Garden selection

Pitaya belongs to tropical and subtropical plants, drought and high temperature resistance, flat land, hillside and sand land can be planted, but it is best to choose slightly acidic land rich in organic matter and good drainage performance.

2. Cultivation methods

Vertical pillar: pitaya cultivation methods are various, but column planting is the most common, production cost is low, land utilization rate is high, the so-called column planting is to erect a cement column or wooden column, let pitaya plants grow along the column, plant 3~4 pitaya seedlings around the column, let pitaya plants grow along the column upward and use plastic rope to bind and fix the cultivation method in sections;

Specifications: column spacing of 1.5×2 meters, according to each column of 3~4 fruit seedlings calculation, mu planting more than 300~400 plants,

Planting: before planting, apply decomposed organic fertilizer to each mu of planting hole, backfill part of soil, mix well, plant seedlings in the hole, and try to make the top of fruit seedlings close to the cement column, pay attention not to deep planting, planting about 3cm deep, the initial stage should keep the soil moist.

3. Water and fertilizer management

Fertilization at seedling stage: thin fertilizer should be applied frequently after planting. Due to the long harvest period of fruits, organic fertilizer, nitrogen, phosphorus and potassium compound fertilizer should be applied every year. Generally, water and fertilizer should be applied once every 10~15 days, mainly nitrogen fertilizer, combined with phosphorus and potassium fertilizer.

Fertilization during growing and fruiting period:

① Fertilizer before flowering (March ~ April): mainly phosphorus and potassium fertilizer, combined with nitrogen fertilizer; compound fertilizer 1~2kg per column;

② Fertilizer for flower and fruit growth (May ~ October): mainly organic fertilizer and compound fertilizer, combined with nitrogen fertilizer; peanut bran 0.5kg+ compound fertilizer 0.5kg per column.

(3) Fertilization after fruit picking (November to February of the next year): mainly organic fertilizer and compound fertilizer; 5kg organic fertilizer (1kg peanut bran)+0.5 kg compound fertilizer per column.

4. Picking and pruning branches

Topping: When the branches grow to 1.3~1.4m long, topping promotes branching, and allows the branches to droop naturally to accumulate nutrients and blossom early.

Pruning branches: after picking fruit every year, cut off the top or weak branches that have already borne many fruits, and let the strong branches left grow new branches again to ensure the yield and quality of the coming year.

5, pest control

Pitaya diseases are mainly stem rot, canker disease, anthracnose and black rot. Generally, it is necessary to strengthen plant nutrition management, improve stress resistance, remove diseased branches in the field in time and select high-quality pesticides for control; secondly, pests are mainly vulnerable to snails and ants in seedling stage, which can be controlled by pesticides.

6. Bagging and timely harvesting

Bagging: should choose paper soft, breathable moisture permeability, moderate transmittance of products, in order to better promote coloring, sugar content rise and early maturity.

Timely harvest: pitaya in the 5~7 days after the flower will obviously increase the fruit room, to 25~28 days after the flower, the fruit gradually turns red from green, and then 5~7 days, the fruit appearance bulging round, and shiny appearance, can be harvested.

The above is an introduction to pitaya planting technology, I hope to help everyone, if you choose to plant, you must first consult the opinions of professionals and buy good varieties of seedlings.
