When will the dragon fruit be planted?

Pitaya is a tropical and subtropical fruit. In its natural state, the fruit ripens in summer and autumn, with sweet and juicy taste, rich nutrition and unique function. It contains plant albumin, anthocyanins, rich vitamins and water-soluble dietary fiber rarely found in general plants. It has a very high cultivation value. Let's take a look at when the dragon fruit will be planted.

When will the dragon fruit be planted?

The dragon fruit can be planted all the year round, but it can not be deeply planted, it can be implanted about 3 times deep, and the soil should be kept moist at the initial stage. It began to blossom and bear fruit 12-14 months after planting, and the fruit-bearing period was from April to November. The fruit was ripe at 30-40 days after flowering, and the single fruit weighed 500kg / 1000g. It produced more than 20 fruits per column in the second year after planting, entered the full fruit stage in the third year, and the higher management level, the per unit yield could reach 2500 kg / mu.

What are the conditions for growing dragon fruit?

1. Temperature: lukewarm dragon fruit is not afraid of high temperature and low temperature, the average annual temperature is not less than 18 ℃, the average temperature in January is not less than 8 ℃, the extremely low temperature is-3 ℃, the duration is not more than 6 hours, the optimum growth temperature is 25: 35 ℃, the temperature below 10 ℃ and above 38 ℃ will stop growing.

2. Soil: the dragon fruit has a wide range of adaptability to soil, and can grow well in mountain, dry land, semi-dry land, stony mountain, wasteland and waterlogged low-lying land, especially the dragon fruit grafted with the local quantity, its adaptability is more extensive.

3. Moisture: the dragon fruit is a drought-tolerant plant, but it needs plenty of water to grow. If the dragon fruit planting land is short of water for a long time, it will cause the dragon fruit growth to stagnate, and even the original stout fleshy stem will slowly wither.

4. Illumination: the dragon fruit is a typical solar plant, which likes warm direct sunlight. If the sunlight time is long and the sun is sufficient, the photosynthesis is especially exuberant, the flesh stem is stout and green, the flowers and fruits are rich and productive, otherwise the amount of fruit is obviously reduced.

5. Fertilizer: the dragon fruit grows fast, and the fertilizer needed in the whole growth cycle must be sufficient. Sufficient nitrogen fertilizer should be supplied in the early growth stage to help the plant grow fast, tall and strong. In the middle and later stages of plant growth, more balanced application of nitrogen, phosphorus and potassium fertilizer should be applied to increase plant photosynthesis.

Planting and management technology of dragon fruit

1. Planting methods: pitaya can be planted in a variety of ways, such as climbing the wall or setting up a shed, but column cultivation is the most common, which has the advantages of low production cost and high land utilization rate.

2. Planting specification: the row spacing of dragon fruit with double-season column is 1.5 × 2 meters. According to the calculation of 4 seedlings planted around each column, 750 plants can be planted per mu. But pay attention not to deep planting, implant about 3 cm deep, the initial should keep the soil moist.

3. Frequent application of thin fertilizer: the harvest time of dragon fruit is long, organic fertilizer should be re-applied every year, nitrogen, phosphorus and potassium compound fertilizer should be applied evenly for a long time, potassium and magnesium fertilizer should be added during flowering and fruiting period, the soil should be kept moist during fruiting period, and the tree plate should be covered with grass or mushroom residue.

4. Coring and pruning: the dragon fruit picks the heart when the branch grows to 1.3 to 1.4 meters long, promotes the branch, and lets the branch droop naturally. After picking fruit every year, cut off the fruiting branches and let them send out new branches to ensure the yield in the coming year.

5. Reasonable interplanting: red dragon fruit has poor self-pollination compatibility, low rate of self-pollination, small fruit and poor marketability, which requires white meat dragon fruit pollination. Interplanting about 10% white meat type dragon fruit can significantly improve the seed setting rate.

6. Artificial pollination: when dragon fruit is planted, artificial pollination should be carried out in overcast and rainy weather. Pollination can be used to apply pollen directly to the female flower stigma with a writing brush before the flowers bloom in the evening or before the flowers are closed in the morning.

7. Pest control: pitaya has fewer diseases and pests, and is vulnerable to snails and ants at seedling stage, so insecticides can be used to control. In the season of high temperature and humidity, it is easy to infect diseases, such as partial branch necrosis and mildew spots, which can be prevented by strychnine, strong copper oxide and so on.
