Description

Technical Field

[0001] The utility model relates to a rice cultivation device, belonging to the field of rice planting equipment. Background Art

[0002] Rice is a kind of herbaceous rice, which belongs to cereal and is also the most important and oldest kind of food in the genus Oryza. Different from upland rice, rice was planted in the Yangtze River Basin of China seven thousand years ago. With the continuous development of society and the continuous growth of population, the annual output of rice can no longer meet the needs of the population. At present, in the field of agricultural facilities, greenhouses are used for soilless cultivation of crops. Since greenhouses can well control indoor temperature, humidity, light, etc., which is conducive to the growth of rice, greenhouse cultivation of rice has been promoted.

[0003] At present, the light regulation of the greenhouse is controlled by a sunshade mechanism. When the sunlight is strong, the sunshade mechanism pulls up the shade cloth to reduce the light. However, the current sunshade mechanism has the following problems: the regulation of the greenhouse is an overall regulation. However, the plants in the greenhouse are exposed to different intensities of sunlight and their growth conditions are also different. Therefore, on the basis of the existing sunshade regulation, a device for regulating local areas of the greenhouse is also needed, so that the plants in the greenhouse can receive the same lighting effect, thereby avoiding the sunlight being too short or too long to affect the growth of the plants.
