Description

A high-strength double-layer arched constant temperature and humidity greenhouse

technical field

The invention belongs to the technical field of agricultural greenhouses, in particular to a high-strength double-layer arched constant temperature and humidity greenhouse.

Background technique

Shiitake mushrooms, also known as mushrooms, mushrooms. Shiitake mushrooms have their own unique growth environment. Shiitake mushrooms have their own unique requirements for temperature, humidity, light and ventilation. Shiitake mushrooms are generally planted in greenhouses, and the greenhouses used to grow shiitake mushrooms should be able to meet the environmental requirements of temperature, humidity, light, and ventilation during the growth process of shiitake mushrooms.

Most of the existing mushroom cultivation greenhouses adopt the structure of the currently mature green leafy vegetable cultivation greenhouses. In the low temperature season, such greenhouses can play a good role in heat preservation and moisture retention, so that the mushrooms can maintain high yield in a low temperature environment. However, in summer in southern my country, the outdoor temperature is often above 36 degrees Celsius, and the temperature in the shed often reaches above 42 degrees Celsius. Such a high temperature can easily lead to rotten bacteria, infection of miscellaneous bacteria, and no fruiting. .

In order to solve the above-mentioned technical problems, those skilled in the art have designed a variety of mushroom greenhouses with different structures, but, the existing mushroom greenhouses generally have the following technical problems when in use: One, the sunshade net and thermal insulation covered outside the existing mushroom greenhouses The membranes are all designed in one piece, which cannot be used for shading, heat preservation and ventilation in different positions of the greenhouse according to the needs. Second, the existing mushroom greenhouses are often of a single-layer steel skeleton structure. When the temperature is too high or too low, it is often impossible to achieve Good heat preservation and moisturizing effect; thirdly, in order to increase the strength of the steel skeleton in the existing mushroom greenhouses, cement piers are often built in the greenhouse and then the greenhouses are fixed on the piers to play a role in resisting wind. By tying wooden stakes in the ground to fix the wind, it often causes great damage to the farmland soil. These measures cannot be used because the current law does not allow cement engineering facilities in the fields, so a high-strength constant temperature and humidity greenhouse is urgently needed. Greenhouses to solve the above technical problems.
