Description

Intelligent grape planting temperature control greenhouse based on environmental parameter monitoring Technical Field The invention relates to the technical field of agricultural facilities, in particular to an intelligent temperature control greenhouse for grape planting based on environmental parameter monitoring. Background Currently, facility grape cultivation has become the dominant mode of high quality fruit production, where temperature and humidity are key factors in determining grape yield and quality. Grape plants have root systems, fruits and canopy leaves which have very different physiological demands on the environment during different growth stages. For example, during the color transition period, the root system needs to maintain activity at a proper ground temperature, while the fruit needs a specific temperature difference to accumulate sugar. Therefore, how to construct a suitable microclimate environment is an important point of modern agricultural engineering. Aiming at the regulation and control of the greenhouse environment, the prior art mainly adopts an operation mode of integral space type heating or fixed point location ventilation. Conventional solutions are usually to house a hot air blower inside the greenhouse or to lay a fixed hot water pipe on the ground. When the system works, according to the temperature data of a single monitoring point, the heating equipment is driven to operate so as to raise the air temperature inside the whole greenhouse, or the ventilation opening at the top is opened to perform natural ventilation by utilizing the thermal pressure difference, and part of facilities can also cooperate with the circulating fans at fixed positions to assist air flow. However, the prior art has short plates in practical applications. The conventional equipment regards the greenhouse as a homogeneous space, and the uniform regulation and control neglects the differential requirements of crops in the vertical direction. The condition that the temperature of the canopy reaches the standard, but the ground temperature of the root zone is still low often occurs, so that a large amount of energy is wasted in unnecessary areas. Grape ears are usually hidden in dense branch and leaf layers, and a closed microenvironment with local high humidity and unsmooth ventilation is easily formed, which is a high-incidence area of fungal diseases such as gray mold and the like. The wind power of the existing fixed ventilation equipment is difficult to penetrate through the thick She Mu and cannot directly reach the surface of fruits. The simple whole shed dehumidification is not only slow in response, but also huge in energy consumption. The method which lacks layering independent control and fixed point intervention capability is difficult to meet the requirements of complex weathers of grapes and disease prevention and control. Therefore, the invention provides an intelligent temperature control greenhouse for grape planting based on environmental parameter monitoring, which solves the defects in the prior art. Disclosure of Invention Aiming at the defects of the prior art, the invention provides an intelligent temperature control greenhouse for grape planting based on environmental parameter monitoring, which solves the problems that the existing greenhouse uniformity regulation and control cannot meet the physiological requirements of grape root, fruit and canopy vertical space differentiation and is difficult to penetrate She Mu to accurately intervene in the fruit field microenvironment of a susceptible disease.
