Seasonal photosensitive self-regulation novel agricultural greenhouse

Abstract

The invention discloses a seasonal photosensitive self-regulation novel agricultural greenhouse, and belongs to the technical field of an agricultural greenhouse. The seasonal photosensitive self-regulation novel agricultural greenhouse can achieve the effects of creatively introducing photosensitive self-regulation balls on an existing agricultural greenhouse and independently regulating proper light facing surfaces in a targeted way by sensing the environment temperature; one surface is used for absorbing light and generating heat to collect solar energy for the greenhouse, and the other surface is used for emitting the sunlight to reduce heat radiation caused by sun irradiation; meanwhile, the light absorption surface can sense the irradiation direction of the sunlight to perform lightfacing regulation; the maximum light absorption surface is always exposed to absorb the sufficient solar energy; the solar energy is effectively converted into heat energy to be stored and to be provided for the greenhouse; the utilization rate of the solar energy is greatly improved, so that the targeted regulation performed by the greenhouse by independently sensing the environment change is realized; the effect of regulating the temperature range is achieved through the feedback on the light illustration; the efficient growth on crops in the greenhouse is guaranteed; and various kinds of cost caused by human intervention are reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural greenhouses, in particular to a new seasonal photosensitive self-adjusting agricultural greenhouse. Background technique [0002] With the emergence of high molecular polymers - polyvinyl chloride and polyethylene, plastic films are widely used in agriculture. In the early 1950s, Japan, European and American countries successfully applied greenhouse films to cover hotbeds, and then covered small sheds and greenhouses with good results. my country introduced polyvinyl chloride agricultural film in the autumn of 1955. It was first used to cover vegetables in small sheds in Beijing, and achieved the effect of early maturity and increased production. The greenhouse was originally a special equipment for vegetable production. With the development of production, the application of greenhouses has become more and more extensive. At present, greenhouses have been used for potted flower and cut flow...

Problems solved by technology

[0003] However, the existing agricultural greenhouse itself does not have the function of temperature regulation. In different seasons, due to the difference in light, the temperature of the greenhouse also changes accordingly. Especially in summer, the sunlight is relatively sufficient, resulting in the temperature in the greenhouse being too high, and certain adjustments are required. Cooling measures, but in winter, there is insufficient light and the ambient temperature is low, and certain heat preservation measures are required, that is, it is difficult for the greenhouse itself to maintain the environment in the shed within a suitable temperature range for crop growth.
