In other words, a fertilizer application roll and a seeding roll are installed on the drive shaft of the delivery unit, and fertilizer and seeds are delivered from a fertilizer tank and a seed tank placed above them, and are supplied to the field through a chute in a separated state. It is composed of

However, since this separate feeding (streak sowing) reduces the fertilizer effect, mixed feeding (mixed seeds) is performed for varieties that allow mixing fertilizer and seeds to be fed. For this mixed feeding, a special machine is used, or a mixture of fertilizer and seeds is put into the tank of the fertilizing and seeding machine for separate feeding, and the feeding operation is performed using only one feeding roll.

(Problems to be Solved by the Invention) In the above-mentioned prior art, the task of switching between the variety desired to be separated and the variety desired to be mixed is troublesome, both in the separate feeding fertilization seeding machine and in the dedicated machine.

The chute 22 is used for streak sowing, while the wide chute 22' is used for wide spread sowing. Member 44
When the fertilizer and seeds are placed at the separation position α and separated and fed out, the fertilizer and seeds fall over a wide area, and although some mixing (semi-mixed feeding) occurs at the center in the width direction of the chute, the fertilizer and seeds are generally separated (Fig. 8D). Further, when the separation member 44 is moved to the mixing position β, the fertilizer and seeds are mixed, and although the fertilizer and seeds are not spread over the entire width of the chute 22', they are fertilized and sown over a wider width than in the previous embodiment (FIG. 8E).

When the separating member 44 is placed at the separating position α with the chute 22' inclined as shown by the imaginary line in FIG. This results in a semi-mixed delivery state (Fig. 8F), which is a combination of separation and mixing. By changing the inclination angle of the chute 22', the width of fertilization and sowing can be changed. In addition, in FIGS. 8A to 8F, the fertilizing seeding machine 1
moves in the direction of arrow H.
