て流亡する等の問題点があった。Among the known fertilization methods, the full-layer method (conventional method) in which the fertilizer is mixed over the entire rooting area, since the fertilizer is mixed into the surface layer, weeds are often increased. The problem is that the fertilizer grows thickly and the utilization rate of the crop is low, so that a large amount of fertilizer is required to obtain a predetermined yield, and the concentration of the fertilizer in the soil becomes uneven and the quality of the harvest becomes unstable. There is a point, and in the method of applying fertilizer in upper and lower two stages, the lower fertilizer is a continuous lateral streak, so that a predetermined amount of fertilizer becomes thin and continuous, thereby immobilizing the fertilizer component, for example, the Linsan component. There was a problem that nitrogen was quickly nitrified and run off.

れる。As described above, the pattern D was obtained from the survey results shown in Table 2.
Fertilization method, that is, if the fertilizer is applied to both sides of the site corresponding to the side of the seeding position as a two-stage upper and lower groups, and the lower stage is more fertilized than the upper stage, as well as the conventional fertilization method, Compared to the spot fertilization method of the above method, a remarkable increase in the yield can be obtained in the total number, total weight and total root weight, and as shown in FIG. 1500g), L class (1050-1200
The ratio of g) was high, while the number of low-grade products with low commercial value was few. From such a phenomenon, the fertilizer application position with respect to the seeding position should be as close as possible to both sides within the range that does not cause fertilizer damage (even if the stock solution is 5 cm apart, there is no obstacle),
As a result, the upper fertilizer is absorbed early and the initial growth is vigorous, and since the fertilizer is not applied to the ground surface, the growth of weeds can be suppressed, and the lower fertilizer in the lower layer is relatively thick and short. Therefore, not only can the required amount of fertilizer be obtained, but also at the same depth, the roots reach and absorb faster than when fertilized in the middle between the strains, as well as preventing the immobilization of fertilizer, It is considered that nitrification (nitrogen) and diffusion are suppressed, and the sustainability of fertilizer effect and fertilizer efficiency can be improved. In addition, the two-stage spot fertilization method on both sides reduced the stock-out rate, and also reduced the incidence of radish, bent root, and fork. Furthermore, the fertilization method of Pattern D is inferior in initial growth as compared to the control plot, which is a full-layer fertilization, but rapidly absorbs nutrients from about the middle of growth about one month after fertilization and grows vigorously. It is presumed that the nutrient translocation efficiency from the leaves to the roots was better than that of the control in the late growth stage when N grew rapidly and N was cut. As a result, the yield was equal to or higher than that of the control.

Also, the present invention can be applied to crops transplanted between strains such as rice. In addition, although the lower fertilizer application amount is set to be twice as large as the upper fertilizer application amount, the upper and lower fertilizer application ratios may be arbitrarily set and changed within a range where the lower fertilizer application amount is larger than the upper fertilizer application ratio.

物の収量を多くすることができる。According to the present invention, when fertilizer is applied in two upper and lower stages below the sowing position or the planting position arranged in rows at substantially constant intervals as described above, the two upper and lower fertilizers are intermittently respectively applied. The fertilizer amount was reduced in the upper row and increased in the lower row, making it possible for the crop to absorb less fertilizer in a timely manner during the growing process with good efficiency and balance, as well as grouping and corresponding to the side of the sowing position or planting position. Therefore, it is possible to increase the yield at a low cost and to increase the yield of a good-quality harvest while reducing the poor quality.
