Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fertilizing method for applying liquid fertilizer, paste fertilizer or granular fertilizer in spots.

[0002]

2. Description of the Related Art Conventionally, when adding fertilizer, paste fertilizer is diluted with it to make liquid fertilizer, which is then put into a tank and sprayed using a power sprayer, or paste paste fertilizer is put into a backpack-type tank and stepped on manually. When the weight was applied to the stepped portion of the type instilling machine and the fertilizer application tube was inserted into the soil, the paste fertilizer flowing down from the tank was instilled into the soil from the tip of the nozzle of the fertilizer application tube. In addition, it is known that spot fertilization is performed by vertically moving a fertilizer application pipe while traveling between crop rows.

[0003]

In the case where the paste fertilizer diluted by using the above power sprayer is sprayed, it is sprayed all over the surface of the soil, so that the fertilizer runs out and the fertilizer is injected into the soil. Not only was it unable to fulfill the original purpose of topdressing, but it was difficult to run the hose from the stationary power sprayer to the spraying position, and it was 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. Furthermore, in the case of injecting fertilizer by vertically moving the fertilizer application pipe while traveling between the rows of crops, the operating part of the fertilizer application pipe that moves up and down reciprocally moves away from the center of the machine body, resulting in a large machine width, When fertilizing near the roots of crops, the foliage of crops growing in a coronal shape was often damaged.

[0004]

According to the present invention, a pair of left and right fertilizer pipes are slanted up and down in an inclined posture in which a lower part is displaced outward from an upper part from an airframe that travels between the lines of a crop planted in a line. The above problem was solved by diagonally penetrating the soil on the outside and applying the fertilizer in the form of dots.

[0005]

[Operation] While the fertilizer applicator is running between the rows of crops planted in the strips, a pair of fertilizer application tubes are tilted such that the upper part of the fertilizer pipe is displaced outward from the upper part, and alternate or simultaneous along this inclined position. The fertilizer is penetrated into the soil diagonally up and down, and when it reaches the bottom end, the fertilizer is discharged from the nozzle at the tip of the fertilizer pipe into the soil to apply the fertilizer in spots. Then, when the fertilizer application tube rises, it moves away from the crops planted on the left and right sides, so that the foliage is not damaged.
