Column-free integrated double-faced sunlight greenhouse

Abstract

The invention discloses a column-free integrated double-faced sunlight greenhouse which comprises a sunny-side greenhouse, a dark-side greenhouse and a middle wall. The sunny-side greenhouse and the dark-side greenhouse share one middle wall. The column-free integrated double-faced sunlight greenhouse is characterized in that the sunny-side greenhouse comprises sunny-side greenhouse horizontal arched shed frames, sunny-side greenhouse longitudinal pull rods, a sunny-side greenhouse outer-layer shed film and a sunny-side greenhouse cotton quilt, wherein the crisscross positions of the sunny-side greenhouse longitudinal pull rods and the sunny-side greenhouse horizontal arched shed frames are fixedly connected; the dark-side greenhouse comprises dark-side greenhouse longitudinal pull rods, dark-side greenhouse horizontal arched shed frames, a dark-side greenhouse outer-layer shed film and a dark-side greenhouse cotton quilt, wherein the crisscross positions of the dark-side greenhouse longitudinal pull rods and the dark-side greenhouse horizontal arched shed frames are fixedly connected. The column-free integrated double-faced sunlight greenhouse is reasonable in structure, convenient to build and maintain and low in construction cost, no column exists in the greenhouse, mechanized operation and daily management are facilitated, and the land utilization rate in the greenhouse is higher than 95%. Heat preservation effect is better, and temperature can be improved by 3-5 degrees.

Description

technical field [0001] The invention relates to an improvement of a solar greenhouse for plants, in particular to a column-free integrated double-sided solar greenhouse. Background technique [0002] With the rapid development of facility agriculture, the share of solar greenhouses in agricultural planting is increasing. It has a great impetus to increase the area of ​​multiple cropping, generate income for farmers, realize agricultural industrialization, and stimulate economic growth. However, the existing traditional solar greenhouses (single-sided) have problems such as low land utilization rate (less than 50%), low temperature requirements, high construction costs, and high operating costs. In recent years, the emerging double-sided solar greenhouse uses the land on the back of the traditional solar greenhouse to build a shaded greenhouse to grow leafy vegetables or fungi and other shade-loving crops, which can effectively solve the disadvantages of low land utilization...

Problems solved by technology

However, the existing traditional solar greenhouses (single-sided) have problems such as low land utilization rate (less than 50%), low temperature requirements, high construction costs, and high operating costs.

In recent years, the emerging double-sided solar greenhouse uses the land on the back of the traditional solar greenhouse to build a shaded greenhouse to grow leafy vegetables or fungi and other shade-loving crops, which can effectively solve the disadvantages of low land utilization in traditional solar greenhouses.

For example, Ningxia Academy of Agriculture and Forestry Sciences applied on July 20, 2010 for the Chinese invention "yin-yang shed solar greenhouse", patent number ZL201020263095.3; Photovoltaic solar greenhouse and construction method", application number 201310427865.1; its shortcomings are: unreasonable structure, various construction materials, high investment in facility construction, and inconvenient maintenance; The effect is poor, the degree of mechanized operation is low and the management is inconvenient, and the land inside the greenhouse is not fully utilized, etc.
