Planting of fire dragon fruit trees in the north

Construction of greenhouses: pitaya in northern China should be planted in greenhouses, and it should be planted in sunlight greenhouses with light transmission and heat preservation. Frame planting: pitaya is a vine succulent plant. Cement frame shall be set up in the shed, and two seedlings shall be fixed on one cement frame. Temperature: Suitable growth temperature is 20-30℃. Reasonable water and fertilizer: compound fertilizer shall be applied when germination, organic fertilizer shall be applied once decomposed before winter, and watering shall be carried out immediately after fertilization. Pruning branches: timely pruning, proper clipping control height.

I. Construction of greenhouses

1. With the improvement of planting technology, pitaya can also be planted in greenhouses in the north now. Generally, solar greenhouses are often used. The cost of such greenhouses is relatively low, and the light transmission and heat preservation are also conducive to the normal growth of pitaya.

2, in order to improve the room temperature, you can cover a layer of straw or corn straw on the ceiling, especially in winter, when the temperature is low, you should cover a layer of straw, such as rainy weather, you need to cover a layer of film on the straw, so as to achieve the best insulation effect.

II. Frame planting

1. Pitaya is a kind of vine succulent plant. After finishing the ground, it should be erected in the shed to facilitate its climbing growth. Steel frame or cement frame can be used. It can be selected according to specific conditions. The more common way of erecting frame is cement frame, which is also convenient to build.

2, in the construction of cement frame can be reasonably allocated according to the plant spacing, in order to facilitate later picking and management, a cement frame fixed at most 2 seedlings, after the construction of cement frame can be planted.

3, before planting should choose to improve the soil, in order to ensure that the nutrients needed for plant growth should be applied into sufficient base fertilizer, control the humidity and temperature in the shed, after planting good watering can be.

Humidity and Temperature

1. Pitaya is planted in suitable soil, maintaining a certain temperature and humidity, and its seedling survival rate is as high as 99%. Management should be strengthened in the later stage, which is conducive to improving the yield and quality of pitaya.

2, pitaya belongs to a tropical fruit, like high temperature, not cold, for the growth temperature requirements are more strict, suitable for growth at 20-30℃ temperature, so we must control the temperature in the shed, so as to ensure the normal growth of pitaya seedlings, at the same time in order to reduce the occurrence of disease, should be timely ventilation.

IV. Reasonable water and fertilizer

The root system of pitaya is shallow, and the absorption of water and fertilizer is limited, so it is not suitable to apply excessive water and fertilizer. The principle of applying more water and fertilizer should be adopted. Generally, nitrogen fertilizer is mainly applied to pitaya.

1, first dig holes around the seedlings, apply about 1000 grams per plant, and then apply compound fertilizer at each germination until the plants bloom.

Secondly, the winter in the north is relatively cold. In order to improve the cold resistance of the plants, organic fertilizer can be applied once to ensure that the plants survive safely.

3, general pitaya watering should be combined with fertilization, so that it is more conducive to plant absorption and utilization, in addition, the plant should avoid waterlogging, such as water must be drained in time.

V. Trimming branches

1. When the plant grows to a certain stage, some old and weak branches and diseased branches should be cut off appropriately, and some new branches that cannot bear fruit in the backlight can be cut off to avoid nutrient loss, thus promoting the rapid growth of the plant.

2, pitaya in the planting year should be properly controlled its height, appropriate decapitation, to prevent excessive growth, affecting the later results and management, the general length of the fruit branches of the plant is up to 1m, otherwise it will lead to malnutrition, but also increase the difficulty of management, so according to the specific situation appropriate pruning of the plant.
