In order to meet the nutrient needs of vegetables, watermelons, melons and other vegetables, and to improve the yield and quality of vegetables, organic fertilizer should be applied before sowing or transplanting.

[0003] Most of the existing fertilization methods are to use a deep fertilization machine to open a groove on one side of the planting belt and spread liquid fertilizer inside the groove. However, most commonly used small hand-propelled deep fertilization machines adopt a single-wheel design, that is, there is a single trenching wheel at the bottom of the cart, and most of these trenching wheels are fixed in size, which is not convenient for adjusting the trenching height. Some deep fertilization machines with trenching wheel height adjustment function generally have an adjustment range that determines the trenching depth according to the diameter of the trenching wheel, and the adjustment range is small. In order to ensure a deeper trenching depth, it is necessary to replace the trenching wheel with a larger diameter, which is not convenient for accurately adjusting the trenching depth during the trenching process.
