Description

Technical Field

[0001] The utility model relates to the technical field of rice cultivation, in particular to a rice cultivation device for rice-shrimp farming. Background Art

[0002] Rice is a cereal crop of the genus Oryza, with the representative species being Oryza sativa. Rice is native to China and India. Seven thousand years ago, the ancestors in the Yangtze River Basin of China had planted rice. The fruit of rice is paddy, and the husk of paddy is called brown rice. Brown rice can be obtained by grinding away the rice bran layer. Nearly half of the world's population relies on rice as their staple food. In addition to being edible, rice can also be used as an industrial raw material for brewing wine and making sugar. Rice husks and rice straw can be used as livestock feed. China's main rice producing areas are mainly the Yangtze River Basin, the Pearl River Basin, and the Northeast. Rice is a direct economic crop, and cooked rice is the staple food of Chinese residents. Due to environmental influences, young rice seedlings need to be cultivated through rice cultivation devices.

[0003] Some existing rice cultivation devices cannot be adjusted according to the rice planting position during use, which affects the growth of rice seedlings to a certain extent, thereby affecting the quality of rice seedlings. In addition, the water level adjustment required for cultivating different varieties of rice has a certain impact on the growth of rice seedlings. Utility Model Content
