Planting technique of dragon fruit

Propagation methods: pitaya can be propagated by cutting, sowing, grafting and so on. Seedling management: the nursery bed should choose the place with good drainage and irrigation, rich in organic matter and good permeability, apply sufficient base fertilizer after soil preparation, plant 1-2 years into the flowering and fruit stage, strengthen seedling management and weed regularly. Watering: plant seedlings and expansion period should keep the soil moist, timely watering in summer, timely drainage in rainy season. Shaping and pruning: the fruiting branches should be cut off in time after harvest every year.

I. Propagation methods

In general, dragon fruit can be propagated by grafting, sowing and cutting. the more commonly used method is cutting propagation, which is simple and convenient to operate, and the survival rate is also high.

The main results are as follows: 1. When the dragon fruit is cut from March to April, the stalk nodes with no diseases and insect pests and strong growth should be selected first, and then they can be cut into several small segments with a length of about 5cm. After they are placed in a cool and ventilated place to dry, they can be cut directly, and then the pillars can be planted next to the plants.

2. After the cuttage is finished, it should not be watered immediately. It should be watered after a week. In general, it will take root in about 2-4 weeks, and the roots can be transplanted to 1cm or so.

II. Seedling stage management

The main results are as follows: 1. The dragon fruit should be selected in the place rich in organic matter, good drainage and irrigation conditions and good permeability as the seedling bed. After selecting the land, the soil can be prepared, sufficient farm manure can be applied, and then ploughed properly to make it mixed evenly.

2. Pitaya will slowly enter the flowering and fruiting stage after 1-2 years of planting, and then the seedling management should be strengthened. According to climate change, soil conditions can be reasonable water and fertilizer, regular weeding, so as to prevent weeds from consuming seedling nutrients and affecting its normal growth.

Third, timely watering

Pitaya is suitable to grow in an environment with sufficient light and water, which is conducive to promoting the rapid growth of pitaya. In the seedling and expansion period of the plant, the soil should be kept moist, especially in the period of high temperature in summer. in order to meet the needs of plant growth, watering should not be excessive, in order to prevent stagnant water in the field, prevent root rot, in case of rainy season, must be timely drainage to prevent diseases and insect pests.

IV. Shaping and pruning

The main results are as follows: 1. The dragon fruit should be properly shaped and pruned when it grows to a certain stage. after each year's harvest, in order to promote the growth of new branches, the fruiting branches should be cut off in time to lay the foundation for blooming and fruiting in the coming year.

2. According to the different growth stages of the plant, different pruning methods can be used, such as truncation, coring, retraction and so on. When pruning, we must pay attention to the strength in order to prevent the occurrence of mechanical wounds and affect the resistance of the plant. In order to improve the permeability of the field, we can properly cut off some branches that are too dense and long, diseases and insect pests can be cut off properly, which can reduce the occurrence of diseases and insect pests and is conducive to better plant growth.
