Dragon fruit cultivation

First, biological characteristics

Pitaya is a tropical and subtropical fruit, drought-tolerant, high-temperature resistant, and hi-light. It does not require strict soil quality. It can be cultivated on flat ground, hillside, and sand-stone land. The optimum soil pH is 6-7.5. The best choice is organic matter. Rich and well-drained land for planting. Pitaya does not tolerate frost, and winter temperatures are below 0°C in simple greenhouses.

Second, planting methods

Pitaya planting methods are various, and they can be planted on the wall or planted on the shelf. However, columnar cultivation is the most common method. Its advantages are low production cost and high land utilization rate. The so-called column cultivation, is the establishment of a cement column or wood column, planted around the column 3-4 dragon fruit seedlings, so that dragon fruit plants grow along the way up the cultivation.

Third, planting specifications double season

The row spacing of the column is 1.5m2m, calculated based on 4 plantlets per column, and 750 plants per 667m2 can be planted. Dragon fruit can be planted all year round. Care must be taken not to plant deep. It should be implanted to a depth of about 3cm. The soil should be kept moist at the beginning.

Fourth, field management

12-14 months after the planting of dragon fruit, flowering results can be obtained. It can be flowered 12-15 times a year, from April to November is the fruit-producing period, the fruit matures after 30-30 days after flowering, the single fruit weight is 500-1000g, the second after planting. Annual production of more than 20 per column, and the third year into the full fruit period, a higher level of management, the yield up to 2500kg/667m2. Its high yield cultivation points are as follows:

1. Thin fat manure: Due to the long fruit harvest period, organic fertilizer should be re-applied every year. Nitrogen, phosphorus and potassium fertilizers should be applied in a balanced manner for a long time. Potassium and magnesium fertilizers are added during flowering to promote the accumulation of sugar in fruits and improve quality. During the result period, the soil was kept moist and the tree tray was covered with grass or mushroom residue. When the weather is dry, water is poured 3-4 days.

2. Topping: When the branches grow to a length of 1.3-1.4m, they pick their hearts, promote branching, and allow the branches to droop naturally.

3. Interspecific and artificial pollination: When planting dragon fruit, it is necessary to plant about 10% white meat type dragon fruit. Pollination between varieties can significantly increase the seed setting rate. In case of rainy weather, artificial pollination should be conducted. Pollination can be applied directly to the female stigma head with a pen before the flowers bloom in the evening or early morning flowers are not closed.

4. Pruning branches: After harvesting the fruit each year, the branches with fruiting branches are cut off and the new branches are re-issued so as to guarantee the output in the coming year.

5. Pest control: Pitaya pests less, seedling stage susceptible to snails and ants harm, can be controlled by insecticides; susceptible to diseases in the high temperature and humidity season, there are some branches of necrosis and mildew, available powder Triadin, strong copper oxide and other prevention The effect is good.

However, the color of the abnormally empty noodles is not good. According to the quality supervision and inspection of the noodle products organized by the General Administration of Quality Supervision, Inspection and Quarantine, it is found that the white noodles are actually added with a whitening agent called benzoyl peroxide. According to the "Sanitary Standards for the Use of Food Additives", the content should not exceed 0.06g/kg, otherwise it will damage human health.
