Description

Technical Field

[0002] In agricultural planting, in order to increase the yield of crops, it is usually necessary to apply various fertilizers to them. Currently, fertilization is mostly done manually and by fertilizer vehicles. Manual fertilization is to manually apply fertilizers in the fields using a fertilizer applicator. This method is not only time-consuming and labor-intensive, but also exposes a large number of crops to human trampling. The manual fertilization method causes the fertilizers to be unable to be effectively distributed around the roots of the crops, and it is impossible to bury the fertilizers directly in the soil for better absorption by the crops. Another fertilization method is to use a fertilizer vehicle to travel in the fields. The fertilization method is changed from manual to mechanical automation, which has high fertilization efficiency and saves time and effort.

[0003] The existing agricultural machinery uniform quantitative fertilization device requires workers to remove weeds in the soil before fertilizing the seedlings. Otherwise, after fertilization, the weeds will become more and more lush and compete with the seedlings for nutrients. In addition, most equipment only sprays fertilizer on the soil surface, and the fertilizer is easily blown away and volatilized, resulting in poor fertilization effect.
