Description

Technical Field

[0001] The utility model relates to the field of rice cultivation, and particularly relates to an auxiliary device for anti-lodging cultivation of rice. Background Art

[0002] During the cultivation process of rice, lodging may occur. The lodging of rice may be due to excessive planting density, where plants compete with each other for sunlight, nutrients, and space, resulting in slender and weak stems that are prone to lodging. Or improper irrigation, as long-term deep water irrigation of rice will cause poor root development, shallow rooting, and weak supporting force. Also, cutting off water too early in the later growth stage of rice will cause the stems and leaves to age prematurely, reducing the anti-lodging ability. At the same time, strong wind is also one of the direct causes of rice lodging, especially in the later growth stage of rice when the plants are tall and the ear weight is large. The base of the rice stem is one of the thinnest and weakest parts of the rice plant, and it bears the weight of the entire plant and the rice ear. Under the action of external forces such as strong wind and heavy rain or poor self-growth, the mechanical strength of the base of the stem is difficult to support and is prone to breakage.

[0003] After the rice lodges, it will cause problems for the rice. Some rice ears are pressed underneath, with poor ventilation and light transmission, affecting photosynthesis, resulting in insufficient grain filling and reduced seed setting rate. Lodging makes the rice grains unable to be normally filled, with inconsistent maturity and a decrease in 1000-grain weight, thus affecting the yield. After lodging, the paddy rice is prone to mildew and germination, reducing the quality of the paddy rice and affecting its processing and edible value. Moreover, the lodged rice cannot be normally harvested by a combine harvester and requires manual harvesting or special harvesting equipment, increasing the harvesting cost.

[0004] Currently, to solve the problems that due to excessive planting density of rice, plants compete with each other for sunlight, nutrients, and space, resulting in slender and weak stems that are prone to lodging, or improper irrigation and long-term deep water irrigation of rice will cause poor root development, shallow rooting, and weak supporting force, rice cultivation can be carried out using a rice planting and cultivation board. The floating board is provided with holes or containers for fixing rice seedlings, and the rice roots can grow in the water below the floating board. However, when using the rice planting and cultivation board for rice cultivation, the base of the rice stem will still break during strong wind weather. Summary of the Invention
