Plastic greenhouse used in summer

Abstract

The invention discloses a plastic greenhouse used in summer. The greenhouse is in the north and south extending direction and comprises a greenhouse body skeleton and a plastic covering film, the greenhouse body skeleton is composed of greenhouse side beams, a top beam and end face skeletons, and the greenhouse side beams, the top beam and the end face skeletons are of lightweight steel structures. Each greenhouse side beam forms a side face, and an arc-shaped top face composed of the top beam is formed between the side faces. The end face skeletons form two end faces, and two double doors are formed in the centers of the end faces respectively. Side ventilation windows are formed in the side faces, and a top ventilation window is formed in the top face. Through optimization, the top ventilation window is formed in the position away from the end faces on the two sides of the greenhouse by 50 cm and is of a horizontal-pushing type structure or a structure of pushing or pulling toward the top. Through the technical measure of arranging the top ventilation window (namely a cooling skylight), the side ventilation windows and the large-size double doors, the cooling speed of the greenhouse used in summer is increased, cooling and warm-keeping effects are good, and the plastic greenhouse used in summer saves cooling energy for over-summer cultivation of crops, and is simple and reasonable in structure, convenient to use and high in territory practicability.

Description

technical field [0001] The invention relates to an agricultural facility, in particular to an agricultural plastic greenhouse. Background technique [0002] At present, my country's protected vegetable industry is developing rapidly. According to the actual vegetable production, agricultural science and technology workers have developed facilities suitable for different seasons and a supporting safe and efficient cultivation technology system, basically realizing off-season planting and annual supply of vegetables. These traditional facilities are also known as greenhouses or greenhouses. [0003] However, due to the hot summer climate in most areas south of the Yangtze River, rampant pests and diseases, and heavy rainfall, the temperature of the small environment in the protected area can easily exceed 40°C. For the growth of vegetables and crops, the above conditions are likely to cause high temperature damage to crops and aggravate pests and diseases, seriously affectin...

AI Technical Summary

Problems solved by technology

[0003] However, due to the hot summer climate in most areas south of the Yangtze River, rampant pests and diseases, and heavy rain, the temperature of the small environment in the protected area can easily exceed 40°C

For the growth of vegetables and crops, the above conditions are likely to cause high temperature damage to crops and aggravate pests and diseases, seriously affecting the normal growth of crops.

Therefore, the traditional agricultural plastic greenhouses have many problems such as high summer temperature, hindered vegetable growth, poor heat preservation effect, etc.

At the same time, the high temperature environment in summer makes it difficult to transport summer vegetables, especially leafy vegetables, and the production of summer vegetables in some areas cannot meet the local market demand
