Vegetable greenhouse

Abstract

The invention belongs to the technical field of mulching films, and particularly discloses a vegetable greenhouse. According to the main technical scheme, the vegetable greenhouse is composed of a shed frame for heat preservation lighting and a shed frame rear wall, wherein the shed frame comprises a dual-layer light transmitting diaphragm plate with a hollow cavity in the middle, an inner layer and an outer layer, and the cavity can be filled with heat preservation materials or evacuated through a logistic pump. According to the vegetable greenhouse of the structure, the labor intensity of a vegetable grower can be relieved in the using process, the good heat preservation performance is achieved, and the land utilization efficiency is effectively improved.

Description

technical field [0001] The invention relates to a vegetable greenhouse. Background technique [0002] Vegetable greenhouses can realize the production of vegetables all year round in temperate and some frigid regions and meet people's demand for fresh vegetables. Especially in winter in northern my country, greenhouse vegetables have become the main production method of vegetables. However, the structure of the currently used vegetable greenhouses is basically composed of a scaffold for heat preservation and lighting and a scaffold back wall formed by a mound of soil with a specific thickness; Both are equipped with thermal insulation straw curtain quilts and roller shutter mechanisms for covering the greenhouse. The vegetable greenhouse with this structure has the following defects: First, the thermal insulation straw curtain or quilt and the roller shutter mechanism not only affect the thermal insulation effect due to the thickness of the cotton quilt, but also the daily...

AI Technical Summary

Problems solved by technology

The vegetable greenhouse with this structure has the following defects: First, the thermal insulation straw curtain or quilt and the roller shutter mechanism not only affect the thermal insulation effect due to the thickness of the cotton quilt, but also the daily bedding and rolling up of the straw curtain or cotton quilt. The labor intensity is extremely high, which seriously affects the production efficiency of vegetable farmers; secondly, using the adobe wall as the supporting back wall of the scaffold not only requires sufficient supporting strength, but also should achieve a better thermal insulation effect than quilts, so the supporting wall The thickness of the body is generally 2-3 meters, and the wall of this thickness will occupy 20% of the area of ​​the greenhouse with a span of 15 meters, which reduces the effective area for vegetable planting.

However, although the vegetable greenhouse with this structure can achieve thermal insulation performance, the liquid circulation in the cavity not only causes great waste, but more importantly, the vegetable greenhouse with this structure is difficult to popularize and use
