Multifunctional arched large-medium canopy

Abstract

A multifunctional arched large-medium canopy comprises an arched canopy frame, an arched canopy jacking rod, fly net agricultural films and sunshade nets. Three fly nets are covered at two ends and the top end of the arched canopy frame, agricultural films are coved outside the fly nets, the sunshade nets are covered at the top end of the arched canopy frame on the outer sides of the agricultural films, and the fly nets, the agricultural films and the sunshade nets are fixed on film clamping grooves through clamping springs respectively. In high-temperature summer and autumn, through proper adjusting, the arched canopy can have functions of insect prevention, sun shading and cooling, ventilation and moisture removal and the like, and normal growing of oversummer vegetables is facilitated; in low-temperature winter and spring, two agricultural films tightly cover the canopy frame in an overlapped manner and cover the fly nets below and the sunshade net above, so that heat insulation effect of the arched canopy is enhanced to some extent, and early-in-spring and delayed-in autumn vegetable production can be realized better. Canopy surface materials are easy to purchase and low in cost, and construction technology is simple and easy to learn and apply by farmers.

Description

technical field [0001] The invention relates to an arched large and medium-sized shed, in particular to an arched large and medium-sized shed which is used for the production of vegetables and horticultural crops and has the functions of preventing insects, ventilating and dehumidifying, and regulating temperature. Background technique [0002] In recent years, with the improvement of people's living standards, people pay more attention to the safety and high quality of vegetable products, and put forward new requirements for summer vegetable production: First, the diversification of vegetable varieties requires the creation of conditions in the high temperature season in midsummer to produce Vegetable products that are not resistant to high temperatures, especially leafy vegetables; the second is to improve the quality of vegetable products, especially to solve the problems of serious insect pests and excessive pesticide residues in summer and autumn, and produce safe and h...

AI Technical Summary

Problems solved by technology

The scientific design of this kind of net room can meet the needs of vegetable production in summer, but the cost is too high for vegetable farmers to bear, and it can only be used in summer and cannot be used in winter; the second is to transform the arched shed used for winter and spring production. Install insect-proof nets on both sides of the shed. This transformation has a certain effect, but the cooling, ventilation, and moisture removal effects are poor, and it is difficult for vegetables to grow normally.
