Description

Technical Field

[0001] The utility model belongs to the technical field of rice drip irrigation, and in particular relates to an adjustable rice drip irrigation device. Background Art

[0002] Rice drip irrigation is an irrigation technology commonly used in rice field irrigation management. Compared with traditional pump irrigation and flood irrigation, it can more efficiently utilize water resources, reduce water waste, and help improve rice yield and quality.

[0003] In the Chinese patent publication number CN216753058U, a rice drip irrigation structure is mentioned, which includes a water tank with a feeding port on the top and a water inlet pipe connected to one side; a water outlet pipe connected to the bottom of the water tank; a coarse filter plate installed in the inner cavity of the water tank; and a plurality of drip irrigation pipes evenly spaced and installed at the bottom of the outlet pipe; wherein the inner diameter of each drip irrigation pipe is not less than 5mm. By adopting the above technical solution, in actual implementation, the fertilizer is dissolved into sufficiently small particles through the setting of the coarse filter plate before it can be discharged from the water tank with the water flow and distributed to each drip irrigation pipe through the outlet pipe, thereby drip irrigation of rice and avoiding fertilizer. Excessively large particles can clog the drip irrigation pipe. By ensuring the inner diameter of the drip irrigation pipe is no less than 5mm, the probability of the drip irrigation pipe being clogged is reduced. Although this device can reduce the probability of drip irrigation pipe clogging, the fertilizer requirements of rice vary significantly during use due to the diversity of its growth cycle. However, the currently commonly used fertilization method often relies on manual judgment and operation to control the amount of fertilizer added. This method makes it difficult to achieve precise control of the amount of fertilizer added, resulting in fluctuations in the fertilizer concentration in the irrigation water. Excessive or insufficient fertilizer can affect the normal growth and final yield of rice.

[0004] In addition, due to factors such as the complexity of terrain and variable soil moisture encountered during rice cultivation, the rice drip irrigation device cannot flexibly adjust the angle of the drip head according to specific circumstances during use, which affects the accuracy of drip irrigation, resulting in uneven distribution of water and nutrients, and unable to accurately meet the growth needs of each rice plant.
