Environmental-control type closed greenhouse

Abstract

The invention relates to an environmental-control type closed greenhouse which comprises a closed greenhouse, wherein a plurality of support upright posts are arranged in the greenhouse, a ceiling is supported at the top parts of the support upright posts, a columnar air duct on which air vents are overspread is attached to the support upright post, enclosing and covering materials are arranged outside the greenhouse enclosed by the support upright posts and the ceiling, a grating-type air-supply perforated plate is paved on the ground, a plurality of cultivating beds are positioned on the air-supply perforated plate, a plurality of air-supply ducts and air-return ducts are arranged at the lower part of the air-supply perforated plate at intervals, a functional air duct is arranged outside the greenhouse, all air-supply ducts are arranged at an air-supply port of the function air duct in parallel, one end of each air-return ducts is connected at an air-return port of the functional air duct in parallel, and the air-return port of the functional air duct is also communicated with the bottom parts of all upright posts; an embedded network environmental-control system and a sensor module are arranged in the greenhouse; and an inner shading device and an outer shading device are respectively arranged at the inner side and the outer side of the ceiling. The invention can be widely applied to various scientific experimental studies or actual production fields, such as environmental control, plant environment physiological feedback, inheritance breeding, plant information detection, and the like, and is especially suitable for the safety test of transgenic plant cultivation.

Description

technical field [0001] The invention relates to facility agriculture, in particular to an environment-controlled airtight greenhouse based on embedded network environment control and isolated from the outside air environment. Background technique [0002] At present, the environment-controlled greenhouses with supplementary light function centered on glass greenhouses or PVC (polyvinyl chloride) greenhouses represent the world's advanced level, and the energy-saving solar greenhouses represent my country's characteristics. The environment-controlled greenhouse is greatly affected by the external environment, and the cost of cooling in summer and heating in winter is very high, and even most of the cost of greenhouse production comes from the energy consumption of cooling or heating, and the environmental control accuracy is low and the gradient is large , the extensive environmental control level is difficult to meet the actual production requirements; although the energy-sa...

AI Technical Summary

Problems solved by technology

The former uses sunlight as the main source of light for plant growth, assists internal and external shading, supplementary light devices, etc. to control the light environment to a certain extent, and uses all means to reduce the energy cost of greenhouse operation. However, due to the influence of the external environment, light The environment is still greatly affected by the external environment, and because no heat insulation material is used, it is difficult to control other environmental factors other than light, such as heating, ventilation, heat preservation, shading and other actuators. It is difficult to optimize the operation of the actuators. There is still no good solution for the comprehensive environmental regulation between

The latter uses a closed environment to solve the problems of lighting and environmental control, but the cost of power operation is much higher than the former
