Description

Technical Field

[0002] Topdressing refers to an agricultural production technology that replenishes the nutrients needed by crops in time during the crop growth period to promote the normal growth and development of crops. After the transplanting of flue-cured tobacco, the new root system has not yet fully recovered, and appropriate nutrient supply is needed to promote the growth and development of the new plants. After transplanting, the flue-cured tobacco cannot absorb nutrients immediately due to severe root damage. Since spring is an important period for the growth of flue-cured tobacco, timely topdressing can help the later growth and yield of flue-cured tobacco.

[0003] Traditional artificial fertilization is generally done manually, which requires people to bend over, which is very physically demanding. In addition, manual fertilization is not accurate in controlling the fertilizer. When there is too much fertilizer, it is easy to cause seedling burn, and when there is too little fertilizer, it is easy to cause the yield and quality of flue-cured tobacco to deteriorate.
