2. Description of the Related Art Conventionally, in the case of additional fertilizer, paste fertilizer is diluted and put into a tank and sprayed using a power sprayer, or paste fertilizer is put into a backpack type tank and a manual step-in type drip is applied. When the weight of the fertilizer application tube was inserted into the soil with the weight applied to the stepping portion of the machine, the paste fertilizer flowing down from the tank was poured into the soil from the tip of the nozzle of the fertilizer tube.

[0003]

When the diluted paste fertilizer is sprayed using the above power sprayer, the fertilizer is scattered on the entire surface of the soil, so that the fertilizer runs off and the fertilizer is injected into the soil. Not only was it not possible to fulfill the original purpose of topdressing, but also the routing of the hose from the stationary power sprayer to the spraying position was cumbersome, making it difficult for one person to work. The latter, which uses a manual foot-operated type pouring machine, can fulfill the original purpose of topdressing, but since it works by multiplying the weight one by one, the topdressing work in the field or the entire large area house is performed. It was very tired to perform, and the efficiency did not improve.
