Sun-shading equipment for open-field strawberry seedling culture and building process of sun-shading equipment

Abstract

The invention discloses sun-shading equipment for open-field strawberry seedling culture and a building process of the sun-shading equipment. Stand columns are symmetrically arranged at the two ends of a seedling culture plot, each group of stand columns comprises a plurality of stand columns, and the stand columns are arranged in the mode that the middle is high and the two sides are low; a cross beam is connected with the stand columns at the two ends of the seedling culture plot, the stand columns on each side of the seedling culture plot are connected through steel wires, and a fixed pulley is arranged on the middle stand column on one side. a sun-shading net covers the stand columns and the cross beam, one side of the sun-shading net is fixedly connected with the steel wires, and a sliding steel rope is arranged on the other side of the sun-shading net; and the bottom of the sun-shading net is connected with the cross beam through C-shaped nails, a pull rope is arranged on the sliding steel rope, and the pull rope penetrates through a fixed pulley to extend towards the stand columns on the other side and extends back to the side where the fixed pulley is arranged to be connected with the sliding steel rope. The sun-shading net is fixed through the C-shaped nails, a certain gap is formed in the middle while the sun-shading net is fixed, and opening and closing of the sun-shading net are facilitated; professional pliers can be used, and building is convenient; and the pull rope and the pulley are combined to facilitate opening and closing of the sun-shading equipment, can be used as a fixing rope and have a windproof function.

Description

technical field [0001] The invention relates to the technical field of strawberry sunshade, in particular to a sunshade device for growing strawberry seedlings in an open field and a construction process thereof. Background technique [0002] Strawberry likes warm and cool climate. The growth temperature of strawberry root system is 5-30℃, and the optimum temperature is 15-22℃. -15°C, flowering and fruiting period 4-40°C. Strawberry likes light but is not resistant to strong light, and likes temperature and coolness but is not resistant to high temperature. When the temperature is higher than 30°C and the sunshine is strong, it is easy to sunburn the leaves, stolons and new stems of strawberry, creating conditions for disease infection. The main cause of a large number of dead strawberry seedlings in the later stage of seedling cultivation and in the early stage of transplanting. Therefore, shade measures must be taken when growing strawberry seedlings. The traditional st...

AI Technical Summary

Problems solved by technology

The traditional steel-frame greenhouses cannot be moved after being built, and cannot be used for large-scale open-field strawberry seedling cultivation, and the covering method of the sunshade net is mainly covered by hand, which requires 3-4 people to operate, which is time-consuming and labor-intensive.
