A Solar Greenhouse Adapted to Southern Climate

Abstract

The invention discloses a sunlight greenhouse adaptive to climates of south of China. The sunlight greenhouse is composed of an arc-shaped arch frame, a plastic thin film covering the arch frame, a heat-insulation quilt, a ventilation window, a canopy mounted at the top of the arch frame and heat-insulation walls arranged at the base part, and is characterized in that one ventilation window is designed at the top of the arch frame; a reversed herringbone canopy is mounted at the top of the ventilation window; a corner for storing the heat-insulation quilt is formed by crossing a supporting rod of the canopy and the arch frame; and the fixed low heat-insulation walls are built on four sides of the base part of the arch frame. With the adoption of the sunlight greenhouse, a series of problems caused by the fact that heat-insulation walls of a previous sunlight greenhouse in the south of China need to be mounted and dismounted each year are solved; and the heat-insulation performance of the greenhouse is improved, and the ventilation, cooling and moisture-reduction capabilities of the greenhouse are enhanced. Therefore, when the sunlight greenhouse is used in the south of China, the temperature in the greenhouse is in a temperature range suitable for growth of warm-season crops to the greatest extent, so that the growth of the crops is facilitated, and the relatively high yield and relatively great economic benefits are obtained.

Description

technical field [0001] The invention relates to a facility for producing vegetables (flowers) and other crops, in particular to a solar greenhouse suitable for producing vegetables (flowers) in southern regions. Background technique [0002] The solar greenhouse has been fully promoted in northern my country, and practice has proved that it is a facility that can significantly increase crop yield, improve crop quality, and significantly increase economic benefits and land productivity. However, transplanting it to the south was unsuccessful. The reasons are analyzed: first, the solar greenhouse in the north has strong heat preservation ability but weak ventilation and cooling ability; second, the temperature in the south is high. Even in winter, when the weather is sunny and warm, the temperature in the greenhouse will rise to 35 degrees or even 40 degrees due to weak ventilation and cooling capabilities, which will seriously affect the growth of crops, let alone in other s...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to not only ensure that the thermal insulation performance and ventilation and cooling performance of the southern type solar greenhouse in the whole winter are improved on the original basis, but also solve a series of problems caused by the installation and removal of the thermal insulation wall every year, so as to promote Popularization and Application of Solar Greenhouse in South my country
