る。However, in the case of the conventional dry field direct sowing method and apparatus, when the rainfall is strong, water pools are formed on the surface of the dry field, and the seeds S are immersed in the water pools. It was a shortage of air, and there was a problem that it rotted before germination. In addition, the excavated soil is covered on the seed S, but when the covered soil is not completely formed, when the covered soil has many large lumps, or when the seed is sown immediately beside the rice stubble. Can not suppress the germination of weed seeds in the soil covered, from the immediate vicinity of the seeds S of rice,
Weed seeds germinate, resulting in a weed-rich paddy field. In addition, it was easily affected by pests and insects, and the yield was low. After sowing, it is necessary to apply fertilizer and to spray a herbicide, which is troublesome. The present invention solves such disadvantages of the prior art.

Then, the seeding groove excavating disc 5 passes along the seeding groove A to form a groove, and the seed S is sown in the groove. This seeding depth is seeded at a depth of 2 to 3 cm from the soil surface. And
A fertilizing groove is formed by the fertilizing disc 6 at a position a few centimeters left and right from the seeding position, and the fertilizer H falls into the fertilizing groove. This fertilization depth is applied to the relatively shallow cultivated crushed soil layer B, and there is no need to cultivate deeply as in the sowing groove A.

The medicine K is sprayed at the rear position of the earthing disc 7 and is crushed by the crushing roller 8. The drug prevents birds and insects from damaging and illness. Furthermore, the chemical solution is sprayed over the front surface after the suppression. This medicinal solution is mainly a herbicide, which prevents weeds from growing in the field scene. The seed S is immersed in a chemical or coated, but may be coated with a gel. If the gel is coated, the water, oxygen, and nutrients required for germination are reduced. Germination efficiency can be further improved because it is contained in the gel, and fertilizers and drugs can be used with slow-acting properties.
