Problems solved by technology

[0002] When fertilizing management in sandy land, due to the topography of the sandy land, organic compound fertilizers are easy to accumulate during fertilization, making the fertilizers stick together, resulting in poor fertilization effect and low slow-release performance of fertilizers, which cannot meet the requirements of the actual planting and fertilization process. Therefore, there is an urgent need to develop a kind of sandy land with high slow-release organic compound fertilizer to solve the problems in the prior art
