Vegetable greenhouse capable of being automatically adjusted according to illumination

Abstract

The invention discloses a vegetable greenhouse capable of being automatically adjusted according to illumination. The vegetable greenhouse comprises a greenhouse roof, a supporting block is arranged at the bottom of the greenhouse roof, an arc-shaped baffle block is welded on the inner wall of the greenhouse roof, a collecting lens is arranged in the greenhouse roof, a receiving plate is arranged at the upper end of the arc-shaped baffle block, and a horizontal plate is arranged at the bottom of the greenhouse roof. A capacitor is arranged in the greenhouse roof, the receiving plate and the horizontal plate communicate with the capacitor through wires, a sliding cavity is formed in the upper end of the arc-shaped baffle block, a sensing device is arranged in the sliding cavity, and an adjusting device is arranged at the bottom of the arc-shaped baffle block. The vegetable greenhouse capable of being automatically adjusted according to the illumination has the advantages that the absorption liquid containing ammonium nitrate can absorb carbon dioxide generated at night, the content of carbon dioxide in the greenhouse at night can be greatly reduced, in the daytime, the absorption liquid can be heated to generate carbon dioxide, the carbon dioxide can be supplied to vegetables, growth of the vegetables can be facilitated, and cyclic absorption and supply of the carbon dioxide can be achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural greenhouses, in particular to a vegetable greenhouse that is automatically adjusted according to lighting. Background technique [0002] Vegetable greenhouse is a frame film structure with excellent thermal insulation performance. Its appearance allows people to eat out-of-season vegetables. Generally, vegetable greenhouses use bamboo structure or steel structure skeleton, covered with one or more layers of thermal insulation plastic. film, thus forming a greenhouse space; the outer film can prevent the loss of carbon dioxide produced by the growth of internal vegetables, so that the greenhouse has a good thermal insulation effect; [0003] However, in the existing vegetables in the greenhouse, when the sun is strong at noon in summer, the vegetables will wither due to excessive sunlight, which will have a greater impact on the growth of vegetables. Therefore, people need to use a blocking de...
