Description

A kind of pitaya cultivation rack and pitaya cultivation method

technical field

The invention belongs to the technical field of pitaya cultivation, and in particular relates to a pitaya cultivation frame and a pitaya cultivation method.

Background technique

Dragon fruit has very high economic value, and integrates the advantages of fruits, flowers, vegetables and medicine. Its fruit is not only edible, but also has very high nutritional value. It is rich in anthocyanins, plant albumin, Vc and dietary fiber, and has become an excellent green health food. Pitaya flower is rich in nutrients and unique in function. It is rich in vitamins, carotene, calcium, phosphorus, and a small amount of anthocyanins and other nutrients beneficial to the human body. It has the effects of improving eyesight, reducing fire, and preventing high blood pressure. Cough, asthma have unique curative effect. Pitaya flowers can be made into dried vegetables as raw materials for soup or to prepare health functional drinks, and become a health food with both vegetables and teas. At present, dragon fruit is planted on a large scale in Taiwan, Guangxi, Guangdong, Hainan, Fujian and other provinces and regions, and has high economic value and good ecological benefits. However, at present, most fruit farmers mainly rely on experience and production summary for dragon fruit planting. Fruit farmers lack management experience and have not made reasonable plans for dragon fruit planting. After dragon fruit is put on the shelves, pruning is unreasonable, resulting in excessive germination and excessive vegetative growth, which reduces the growth rate of dragon fruit. Fruit setting rate, in addition to the lack of disease management technology, resulting in low yield, poor quality and low output value of dragon fruit.

Dragon fruit belongs to tropical and subtropical fruits. It likes warmth and humidity. The optimum temperature for growth is 25-35 degrees Celsius. If the temperature is lower than 5 degrees Celsius, it will stop growing, and if it is lower than zero degrees Celsius, it will cause freezing damage. Therefore, dragon fruit in most parts of my country Facilities must be cultivated to survive. The support mode (abbreviation "shelf") of dragon fruit directly affects field operation and management efficiency. At present, the main support modes include continuous row (hedge) type, single column type and ring type. The application of continuous rows of racks in flat pitaya orchards is increasing day by day. It mainly uses cement columns (or steel pipe columns) and steel strands (or steel pipes, iron bars) as support materials to plant them in a vertically continuous hedge, allowing the branches to extend to both sides. Side pendulous growth. The direction of row-type racks is preferably from north to south, so that the light is more evenly received.

The overall height of the connecting rods of the existing row-type brackets is >160cm, which is not conducive to pruning and other operations and management, or the height of the connecting rods is <130cm, which makes the overall height of the fruiting branch curtain lower, the space utilization rate is low, and it is not conducive to the ventilation of the orchard. There is no cold-proof film line, and when the film is covered to prevent frost in winter, the thorns of the branches are easy to pull the film, the efficiency of the film cover is low and the film is easy to tear, which affects the heat preservation effect. Without cross arm and support wire. As a result, the opening angle of the branch is too small, and the utilization rate of light energy is low. There is no fixed tie wire on the supporting branch line. The fruiting branches are not neatly placed, easy to overlap and stagger, the number is not fixed, the length is different, and the quality of each fruiting branch is inconsistent. The drip irrigation belt that runs close to the ground is usually used, resulting in a narrow wet surface of the tree plate, and easy seepage and loss of water and fertilizer, which is not conducive to the extensive growth of fibrous roots and weeding and spreading organic fertilizers. The pillar adopts the A-type support method as a whole, which increases the overall stability of the support, but also narrows the width of the operation path between rows, which is not conducive to field machinery operation.
