At the same time, the rocking link 4a of the planting rod 4 is projected upward, and its projecting end connects the valve arm 14a of the switching valve 14 with the rod 15 so that the rocking valve 14 'of the switching valve 14 is constantly rotated. The structure of the switching valve 14 is configured so as to operate in conjunction with the planting rod 4, and the structure of the switching valve 14 is shown in FIGS. That is, in the vicinity of the planting position of the seedling P, the valve arm 14
When a is tilted backwards, fertilizer a is discharged from the shallow fertilizer application port 8 (see FIG. 7), and when the valve arm 14a is in the neutral position, the fertilizer application ports 8 and 9 on both the shallow and deep layers are applied. Fertilizers a and a'are discharged (see Fig. 6), and until the next planting starts, fertilizer a'only from the deep fertilizer application port 9

It is convenient because it is not completely interrupted. Moreover, since the flow of the pressure-fed fertilizer from the fertilizer application pump 11 is not interrupted, the internal pressure of the discharge hose 13 does not intermittently rise suddenly, and therefore the fertilizer clogging sensor can be used. There is no inconvenience that adversely affects (not shown) or damages the hose 13 or the like. The present invention can be installed not only in the riding rice transplanter but also in the walk type rice transplanter area in a paddy working machine such as a submerged direct soil sowing machine.

予め設定された施肥深さに正確に保持される。In the above structure, when the planting clutch is turned on to move the machine forward and the fertilizer application pump 11 is started to start the work, the paste fertilizer in the fertilizer tank T is sucked in by the suction hose 12, the fertilizer application pump 11, and discharged. After being sent to the rear of the aircraft via the hose 13 etc., each planted seedling P is planted from the shallow fertilizer port 8 to the adjacent lateral strip shallow layer position and from the deep fertilizer port 9 with planting. At the same time, fertilizer is applied to the deep position on the opposite side across the seedling P. In this way, since the fertilizer is applied to the shallow layer and the deep layer of the field separately in the vertical step state and left and right,
Fertilizer a applied to the top and bottom of the field at a predetermined fertilization depth,
The a'is not affected or disturbed by the other fertilizer application ports 8 and 9 and is not disturbed or moved, so that the a'can be accurately maintained at the preset fertilization depth in a stable mud state.

ズに行われる。Therefore, the fertilizer a for the shallow layer improves the survival and growth in the early stage of growth, and the fertilizer a ′ for the deep layer.
As a result, the fertilizing effect in the middle stage of growth is given, so that the fertilizers a and a'applied up and down are efficiently absorbed according to the growth of the seedling P. Moreover, since a larger amount of fertilizer a'is applied to the deep layer than to the shallow layer, the seedling P is placed at the fertilizing position of the deep layer.
The fertilizer a ′ fertilized in the deep mud during the period until the roots of the root grow until there is a shortage of fertilizer for top-dressing and even if there is some runoff due to diffusion, it will not run out of fertilizer or become insufficiently absorbed. Since it is possible to expect an increase in yield and omit the additional fertilization that accompanies the growth of the seedlings P, a great labor saving can be achieved. Since the fertilizing operation is performed under the field conditions where the mud after scraping is soft and the soil is leveled, the mud fertilization is smoothly performed without mud resistance.

初期の活着・成育に所定の肥効を奏するものである。INDUSTRIAL APPLICABILITY As described above, according to the present invention, in parallel with planting or sowing of seedlings, the paddy field is adapted to be fertilized simultaneously at the upper and lower two steps of the shallow part and the deep part of the field and at the positions separated left and right. In the working machine, the fertilizer entrance of the shallow fertilizer is provided in the shallow part of the field, and the fertilizer entrance of the deep fertilizer is provided in the deep part.
Since the amount of fertilizer applied to the deep-layer fertilizer is larger than that to the shallow-layer fertilizer, fertilizer is applied to the field, the shallow layer and the deep layer at two separate vertical and horizontal positions. The fertilizers applied to the respective predetermined fertilization depths are accurately held at the preset fertilization depths without being disturbed or moved due to the influence of the other fertilization mouth or the like.
Also, since the fertilizer applied to the deep layer is larger than the fertilizer applied to the shallow layer, the appropriate amount of fertilizer applied to the shallow layer, which is close to the crop, has adverse effects such as growth delay and quality deterioration due to fertilizers and burns. Without using the fertilizer, the fertilizer in an amount necessary for the initial growth exerts a predetermined fertilization effect on the survival and growth in the early stage of growth.

ると共に、一層の増収を図ることができる。The fertilizer applied to the deep layer is larger in amount than the shallow layer, but is separated left and right from the shallow layer fertilized area and left and right, and downward from the planting or seeding position of the seedlings. Since the fertilizer is applied to the fertilizer, it will not be absorbed by the crop immediately after planting or sowing, and the effect will only come out when the crop grows and the root has fully grown and reached the position of additional fertilizer. It does not happen. Moreover, even if some fertilizer is diffused in the mud and is washed away, the top-dressing fertilizing effect in the middle growth period is not impaired. In this way, the fertilizer applied up and down is efficiently absorbed according to the growth of the seedlings, which can eliminate the additional fertilization that accompanies the growth of the seedlings and achieve significant labor saving and further increase in the yield. it can.
