Problems solved by technology

[0004] At noon in summer, due to the high temperature, the transpiration of the leaves is enhanced, and the speed of plant water absorption cannot keep up with the speed of water loss, which will cause the stomata of plant leaves to close, reduce the carbon diox

Embodiment 1

[0043] see Figure 1-8 , a shading device for a greenhouse, comprising a greenhouse body 1, see Figure 1-2 The upper side wall of the greenhouse body 1 is fixedly connected with a plurality of installation cylinders 2, and the upper end of the installation cylinder 2 is fixedly connected with a fixed seat 3, the upper end side wall of the fixed seat 3 is a groove, and the side of the fixed seat 3 is bonded There is a thermal insulation film 17, so that the heat conduction rod 4 can absorb heat when the sun is directly shining, so as not to open the reflector 13 when the plants carry out normal photosynthesis, and the heat conduction rod 4 is inserted in the installation tube 2, and the heat conduction rod 4 The upper end runs through the fixing seat 3, and the lower end of the heat conducting rod 4 is covered with an elastic shell 5, which is a sealed structure, and the inside of the elastic shell 5 is filled with air, which will expand after being heated, which can increase ...

Abstract

The invention discloses a shading device for a greenhouse and a using method thereof, and belongs to the field of greenhouses. According to the shading device, a reflector is arranged to block solar rays, the temperature in the greenhouse at noon can be reduced, plants are prevented from withering and even dying due to a large amount of water loss, and an elastic shell is expanded by a large amount of heat generated by perpendicular incidence of the solar rays at noon, so that the horizontal plane is raised, and dynamic balance weight balls move upwards. Meanwhile, memory metal sheets are deformed by heat so as to open openings in a magnetism isolating cover to allow magnetic induction lines to pass through, so that magnet balls generate upward attraction force on magnetic lifting ropes, and the reflector is gradually rotated from a vertical state to a horizontal state under the driving action of upward floating of the dynamic balance weight balls so as to block light rays; After sunlight deviates, along with heat dissipation, the magnetism isolating cover is closed, so that the magnet ball loses the adsorption effect on the magnetic lifting rope, the reflector is pulled back intothe containing groove under the gravity effect of the dynamic balance weight ball, and normal photosynthesis of plants is guaranteed.

Description

technical field [0001] The invention relates to the field of greenhouses, in particular to a shading device for a greenhouse and a method for using the same. Background technique [0002] Greenhouse, also known as greenhouse, refers to a room with cold protection, heating and light transmission facilities for cultivating temperature-loving plants in winter. In seasons that are not suitable for plant growth, it can provide a growth period and increase yield. It is mostly used for planting or raising seedlings of temperature-loving vegetables, flowers, forest trees and other plants in low temperature seasons. A greenhouse is a building that can control or partially control the growing environment of plants. It is mainly used for non-seasonal or non-regional plant cultivation, scientific research, additional breeding and ornamental plant cultivation, etc. [0003] Greenhouses can provide a growth period and increase production in seasons that are not suitable for plant growth...
