Pitaya has high economic value and rich nutrition, and is the best food for eating, health care and medicine. The crown of pitaya is beautiful and huge, and the fruit can make all kinds of delicious dishes. Pitaya can also protect the environment and purify the air. It absorbs carbon dioxide and releases oxygen at night, which is a great contribution to mankind and a good project that benefits for life.
Cultivation method
When raising seedlings, you should choose a place with sufficient sunshine, smooth drainage, good base fertilizer and good scaffolding. At present, we adopt two planting methods. (1) scaffolding method. The first column, scaffolding along the shed, 4 plants per 667 square meters; (2) the crossbar drooping method. Use columns at both ends and a crossbar in the middle. The seedlings are planted under the crossbar, and the two sides hang down behind the crossbar. This method is convenient for selection and management. It is beneficial for branches to absorb underground temperature and moisture, and can also increase yield and increase efficiency. Planting row spacing and plant spacing: row spacing 1.5m, plant spacing by drooping method is generally 30cm, planting method is 70-80cm, and each box contains 3-4 plants.
Planting time
Pitaya can be planted in spring, summer and autumn. After 14 months, it can sprout, blossom and bear fruit.
1. Seedling management. Seedlings grow rapidly, and temperature and humidity are very important. The temperature should be between 20 and 34℃ and the humidity should be between 60% and 80%.
After 2.6 months, the seedlings grew into medium seedlings, and the medium seedlings with a height of 1.3 ~ 1.4 meters began to branch, with 4 ~ 6 branches per plant. When the branches grow to 1.2 ~ 1.3 meters, they are capped, and the capped branches quickly plump and grow buds. This is 14.
There won't be many fruits in the first year, so there is no need to prune. In winter, the temperature should be controlled well, and no new buds should be left on the branches, so as not to affect the annual output in the future. Pruning began after the fall of the following year, so that the old branches with long fruits could keep new branches. At this time, high temperature is needed, and new branches will grow rapidly. Increase production and income in the coming year, and the fruit trees have reached their full fruiting stage.
4. Result period management. The fruit stage is the time when water and fertilizer are most needed, so it is necessary to apply them frequently and thinly to ensure the branches need them. The branches are full, the pulp tastes better, and the organic fertilizer can be combined with chicken manure, which has good taste, long fertilizer effect and sufficient stamina. Pure green high-calcium potash fertilizer can also be applied in moderation, but chemical fertilizer is not allowed.
5. Pest control. There is a layer of wax on the skin of pitaya, and there is not much disease. Meat will rot only if there is poor ventilation in the shed. Scrape off the rotten meat and coat it with lime powder. The natural enemies of pitaya are ants and snails. As long as the mosquito killer is sprayed, it can be prevented from eating fruits and flower buds.
