Analogue simulation anti-solarization greenhouse and sun-proof method thereof

Abstract

The invention belongs to the field of plant culture, and particularly relates to an analogue simulation anti-solarization greenhouse and a sun-proof method thereof. The greenhouse comprises a greenhouse body internally provided with a simulation shell. The top wall of the greenhouse body is composed of a liquid crystal assembly. A liquid storage chamber is formed in the simulation shell, an electrolyte solution is arranged in the liquid storage chamber, the side wall of the liquid storage chamber communicates with a water adding pipe capable of adding water into the liquid storage chamber, anannular floating plate floats on the surface of the electrolyte solution, simulation leaves capable of simulating the transpiration of plant leaves are fixedly connected into the floating plate, two electrode plates arranged in parallel are arranged in the liquid storage chamber, the electrode plates are electrically connected with an electromagnet, and the electromagnet can control whether the liquid crystal assembly transmits light or not. By simulating the transpiration of the plant leaves, the state of the plant can be judged more accurately, then whether the plant needs to be shaded or not is judged more accurately, and the plant can be shaded only when the plant needs to be shaded.

Description

technical field [0001] The invention belongs to the field of plant cultivation, and in particular relates to a simulated anti-exposure greenhouse and a sun-proof method thereof. Background technique [0002] Greenhouse is a kind of greenhouse used to cultivate plants. Generally, the top of the greenhouse is a transparent structure, which can realize sufficient light inside the greenhouse through the transparent roof, and can meet the needs of plants for light through natural light, and then do not need to artificially supplement plants through electric lights. Light, which in turn can greatly save energy. [0003] However, just because the top of the greenhouse is a transparent structure, in summer and other high temperature weather, the sunlight is often too strong, which makes the temperature of the plant leaves inside the greenhouse too high and the plant leaves are burned. At the same time, the transpiration of plants in high temperature weather is accelerated, making P...

Problems solved by technology

[0003] However, just because the top of the greenhouse is a transparent structure, in summer and other high temperature weather, the sunlight is often too strong, which makes the temperature of the plant leaves inside the greenhouse too high and the plant leaves are burned. At the same time, the transpiration of plants in high temperature weather is accelerated, making Plants are prone to dryness due to lack of water. At present, the most convenient and effective method is to prevent the plants in the greenhouse from being exposed to the sun through the method of sunshade nets. However, at present, it is basically directly judged by the temperature whether the plants need to be shaded, but in fact the plants The evaporation of water is also affected by other environmental factors such as humidity. Judging only by temperature, it is impossible to determine whether plants need sunlight or shade
