Specifically, in the agricultural greenhouse of the embodiment, the photovoltaic power generation films 10 are arranged on the light transmission surface of the greenhouse 1, the photovoltaic power generation films 10 are arranged in a staggered manner, and because the illumination direction of the sun in the daytime is changed from time to time, the photovoltaic power generation films 10 arranged in the staggered manner can ensure that crops in different position areas in the greenhouse 1 can obtain enough illumination, preferably, the photovoltaic power generation films 10 adopt amorphous film solar cells which have a light transmission effect and can transmit external red light and blue light into the greenhouse 1 to meet illumination required by plant growth, and because the photovoltaic power generation films 10 are directly arranged on the light transmission surface of the greenhouse 1, the area of the photovoltaic power generation films 10 can be effectively increased, and the power generation amount is improved. The electric energy generated by the photovoltaic power generation film 10 is stored in the storage battery, and the controller controls the relevant electric appliance parts to supply power for operation. Wherein, the lateral wall of big-arch shelter 1 adopts vacuum insulation board to keep warm, vacuum insulation board has good thermal insulation performance, and vacuum glass board 12 is adopted at the top of big-arch shelter 1, vacuum glass board 12 can ensure that 1 top of big-arch shelter has good thermal insulation performance, thereby realize night in winter, need not the user and hide the heat preservation curtain on big-arch shelter 1, in addition, adopt the light-permeable face that polylith vacuum glass board 12 concatenation formed big-arch shelter 1, vacuum glass board 12's life is longer, can avoid adopting the transparent film to need often change and the trouble that brings. The water supply pipe 2 is buried under the ground in the greenhouse 1, the water collecting tank 13 is further arranged on the light transmitting surface of the greenhouse 1 to collect rainwater and store the rainwater in the water tank 3, when irrigation is needed, the controller controls the water pump to be electrified, the water pump conveys water in the water tank 3 into the water supply pipe 2, the water pressure in the water supply pipe 2 is increased, so that the water outlet hole 20 of the water in the water supply pipe 2 is discharged, crop roots in soil are directly irrigated, in the actual use process, the fact that the water supply pipe 2 supplies water at the depth position of the roots 101 of the crops 100 below the ground, the water output from the water supply pipe 2 flows downwards under the action of gravity, the roots 101 of the crops 100 have water, the water in deep soil is high in content, the roots 101 of the crops 100 can be attracted to be deeply rooted underground, the crops 100 can grow in a more vigorous state, and high-quality agricultural products can, meanwhile, the water output by the water supply pipe 2 is prevented from being evaporated in a large amount, and the water consumption is reduced. And for the ground surface in the greenhouse 1, as no water is supplied, the soil layer on the ground surface is in a dry state for a long time, so that weeds growing on the ground surface cannot survive, and the labor intensity of farmers for weeding is reduced. In order to improve the light transmittance of the vacuum glass plates 12, a shower pipe 121 is disposed at the upper edge of each vacuum glass plate 12, the shower pipe 121 is connected to the water tank 3 through a cleaning pump (not shown), during the actual use, the light transmittance of the vacuum glass plates 12 is reduced due to dust and other factors, at this time, high-pressure water is injected into the shower pipe 121 through a nozzle of the shower pipe 121 through the cleaning pump to clean the surfaces of the vacuum glass plates 12, and the water flowing from the vacuum glass plates 12 flows back to the water collecting tank 13 and flows into the water tank 3 again through the water collecting tank 13 for reuse, and a filter screen is disposed at the inlet of the water collecting tank 13 or the water tank 3 as required to filter impurities entering the water tank 3.
