Pitaya semi-closure three-dimensional cold-and-frost resistance structure

Abstract

The invention provides a pitaya semi-closure three-dimensional cold-and-frost resistance structure. The structure comprises concrete pillars, cross arm supports, support rods, an arch frame, keel, fixing steel wires, connection steel wires, and thermal insulation film, support rods are arranged on the upper part of the concrete pillars, the top ends of the support rods are connected with one end of the keel, the other end of the keel is connected with the top ends of the support rods of adjacent concrete pillars, the two sides of the top ends of the support rods are respectively connected with the upper end of the arch frame, the lower end of the arch frame is connected with the cross arm supports, the fixing steel wires are passed through the hollow holes in the upper parts of the concrete pillars and connected with the middle parts of the cross arm supports, the cross arm supports are fixed on the concrete pillars, the bottom end of the arch frame and the bottom end of the arch frame of adjacent concrete pillars are connected through the connection steel wires, the thermal insulation film is decked on the arch frame, the keel, the cross arm supports and the connection steel wires. The pitaya semi-closure three-dimensional cold-and-frost resistance structure is good in cold-and-frost resistance effect, low in cost, promotable in vast regions, and provides a solution to the problem that unattached drooping branches of the pitaya are susceptible to being broken by wind.

Description

technical field [0001] The invention belongs to the field of pitaya planting, and in particular relates to a semi-enclosed three-dimensional pitaya structure for preventing cold and freezing. Background technique [0002] Dragon fruit, Cactus, Liangtianchi plant, also known as red dragon fruit, dragon fruit, fairy honey fruit, jade dragon fruit. Fruit, oval, 10-12 cm in diameter, red or yellow in appearance, with green rounded triangular fronds, white, red or yellow pulp, fruit with black seeds. Dragon fruit is rich in nutrients and has unique functions. It contains vegetable albumin and anthocyanins, which are rare in general plants, rich in vitamins and water-soluble dietary fiber. Dragon fruit is a cool fruit. Under natural conditions, the fruit matures in summer and autumn, and is sweet and juicy. As a subtropical plant, dragon fruit likes high temperature and slight humidity. The best growth temperature is 22-32 degrees. If the temperature is too low, the fruit seedli...

Problems solved by technology

[0004] In order to solve the above problems, the inventor provided a semi-enclosed three-dimensional cold-proof and anti-freeze structure of pitaya after repeated tests. The disadvantage of area promotion also solves the problem that the drooping branches of dragon fruit are not anchored and broken by the wind
