Embodiment Construction

[0038] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0039] Let’s take a 25m*40m rectangular plot as an example to build a grid-type long-span rectangular dome energy-saving greenhouse without pillars. Its construction steps are as follows:

[0040] 1) The land used for building the greenhouse is 25 meters wide and 40 meters long ( figure 1 ), covering an area of ​​1,000 square meters, it is planned to build a rectangular grid greenhouse with a shoulder height of 3.6 meters and a dome height of 10.6 meters ( figure 2 ).

[0041] 2) Use CAD drawing software to draw the steel frame diagram of the greenhouse ( image 3 ) and a three-dimensional model, including the dome and the vertical grid struc...

Abstract

The invention discloses a wire-frame-type large-span supporting-column-free moment-type doom energy-saving green house construction method suitable for annual restless production, and belongs to the technical field of green houses. According to the method, the top is constructed as a doom by using a steel-structured wire frame, the ground edge is a moment-type large-span supporting-column-free green house steel structure, a green house internal wire frame platform is utilized to implement heat preserving quilt covering to achieve heat preserving effect in cold seasons, a green house internal water wall heat reserving technology is combined, dynamic controllable heat preserving, heat reserving and heat dissipating are achieved, and therefore restless production of vegetables and fruits in the cold seasons without heating is achieved. The moment-type configurations of wet curtains and fans at two ends are combined, ventilation temperature reduction culturing on high-temperature summer days is achieved to ensure the annual restless production of green house crops no matter in cold areas or in warm areas, and the method is an integrated innovation of a structure technology and a regulating technology in the field of green houses.

Description

technical field [0001] The present invention belongs to greenhouse facilities. The invention relates to a new type of greenhouse structure and a new method of energy-saving environment regulation, which is used for greenhouse cultivation of economic crops for agricultural production, and realizes year-round production. Background technique [0002] Greenhouse technology has a long history from its invention to the present. The earliest Roman Empire began to use mica as a cover to build greenhouses for cucumber production from 3 BC to 37 AD; France used glass to cover hotbeds for vegetable cultivation in the 17th century. A simple glass greenhouse was built; before the invention of glass, oil paper was used as a cover in the Tang Dynasty in my country, and the simple greenhouse cultivation was heated with hot spring water; in the middle of the 20th century, with the development of the plastics industry, especially the emergence of agricultural films , which has promoted the po...
