[0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a drip irrigation and fertilization device based on crop root and soil moisture detection. Background Art

[0002] The agricultural planting process is greatly affected by natural factors. In order to reduce the dependence of agricultural planting on natural factors or locally control the growth environment of crops and ensure the yield of crops, human intervention is required. Among them, artificial control of fertilization and irrigation is a commonly used means of agricultural planting regulation.

[0003] In the existing crop planting process, it is necessary to reasonably distribute fertilizer and water according to the soil moisture conditions to achieve refinement and control, reduce production cost investment and increase yield at the same time; there is no device in the existing technology that detects the roots and moisture conditions of crops to cooperate with the global drip irrigation and fertilization operation according to the local detection results during the crop planting process. Most of the existing technologies are manually digging the soil layer and observing in the farmland, which is not only inconvenient to operate and causes great damage to crops, but also the location of each observation or sampling is not easy, resulting in inaccurate detection results. Therefore, the drip irrigation and fertilization amount cannot be finely controlled, resulting in a certain degree of error. Summary of the invention
