Description

Technical Field

[0001] The utility model belongs to the technical field related to agricultural fertilization, and specifically relates to a fertilization tool. Background Art

[0002] Fertilization refers to the agricultural technical measures of applying fertilizer to the soil or spraying it on plants to provide the nutrients required by plants and maintain and improve soil fertility. The main purpose of fertilization is to increase crop yields, improve crop quality, improve soil fertility and improve economic benefits. Therefore, reasonable and scientific fertilization is one of the main means to ensure food security and maintain sustainable agricultural development. The main fertilization modes include broadcasting, flushing, hole application, strip application, etc. In order to improve the accuracy of fertilization and improve the nutrient absorption rate of fertilizers, precision fertilization tools have appeared on the market. The tool is a tubular structure with a head at the lower end. When inserted into the ground, the soil on the ground is brought up and the fertilizer is placed in a small pit formed on the ground. Then the soil in the tool is discharged and covered on the fertilizer. The fertilization tool can meet the needs of precision fertilization, but because the soil enters the pipe, it is easy to get stuck. It is inconvenient to discharge the soil downward, resulting in low fertilization efficiency. In addition, the subsequent use of soil to cover the fertilizer is prone to incomplete fertilizer coverage, resulting in rapid volatilization of the fertilizer, affecting the fertilization effect.
