Next, the operation will be described. When the floor soil 5 is supplied to the supply hopper 19 of the floor soil supply device 18 and the seedling raising container 1 is supplied to the transfer table 15 in this state, the floor soil 5 is supplied when passing through the lower portion of the floor soil supply device 18. Then, the excess soil is scraped off by the rotating leveling brush 21 to level the level, and the supply of the floor soil 5 is completed. Since the rotating leveling brush 21 cannot scrape the soil inside the front wall 29 and the rear wall 28 of the seedling raising container 1, corner soil remains in an arc shape.
To remove. Therefore, the seeds 6 and the medicinal effect-controlling insecticide 10 are prevented from moving, and are prevented from gathering at the corners. Next, the seedling raising container 1 reaches the lower part of the watering device 50, is irrigated through the watering hole 52 of the watering pipe 51, receives the supply of the seeds 6 under the seed supply device 60, and receives the seeds 6 under the covering material supply device 64. A thin covering 7 is put on the upper side, and the seeding is completed. In this case, since the medicine controlling insecticide 10 is sprayed by the medicine spraying device 70, the work of mixing the medicine controlling insecticide 10 into the floor soil 5 in advance is unnecessary, and a desired amount of the medicine controlling insecticide 10 is sprayed. it can. In addition, since the medicine dispensing operation can be mechanized by the medicine spraying device 70, the operation is extremely simplified. Further, by adjusting the position of the sliding brush 76 with the dial 82 of the medicine spraying device 70, the amount of the drug-adjustable insecticide 10 to be dispensed can be adjusted, so that the optimum amount can be sprayed for each type.

That is, since the medicinal effect-controlling insecticide 10 capable of controlling the elution time and the elution amount of the drug component is sprayed on the floor soil 5, the spraying of the drug after transplanting the grown seedlings can be reduced. Reduce drug costs. In particular, in the case of seeding of paddy rice, seedlings are raised in a seedling raising container 1 and transplanted to a field by a rice transplanter. Even if the machine is used, it can be sprayed at the same time as seedling transplantation, omitting work,
Work can be reduced. Further, since the medicinal effect-controlling insecticide 10 is inserted into the soil of the field together with the floor soil 5, unlike the case where the pesticide is directly sprayed on the water of the paddy field, the drug component does not flow into the water of the paddy field. In addition, it is possible to reduce drug costs, prevent drug outflow, and protect the environment such as water quality. In addition, compared to a simple drug, there is no burning of the drug, and even if the root is entangled with the drug-controlling insecticide 10, there is no obstacle and the drug absorption is assured and a uniform drug effect can be obtained. Since the medicine spraying device 70 is provided with the medicine feeding roll 72 in the direction crossing the transport direction of the seedling raising container 1, the drug-effect-controlling insecticide 10 fitted into the feeding recess 73 of the medicine feeding roll 72 is a derivative. It is guided to the lower position by 77 and falls into the seedling raising container 1. At this time, about 50 g is sprayed per box.

In this case, since the medicine feeding roll 72 is formed to be narrower than the width of the seedling raising container 1,
The insecticide 10 is prevented from scattering on the left and right sides of the medicine. In addition, a container detecting unit 81 is provided below the medicine feeding roll 72 in the transport direction, and after a predetermined time has passed since the container detecting unit 81 detected the seedling raising container 1,
Is rotated, and after a predetermined time has elapsed from the start of rotation, the rotation of the medicine feeding roll 72 is stopped.
Is detected by the container detecting section 81, and after the front wall 29 passes below the medicine feeding roll 72, spraying of the medicinal effect-controlling insecticide 10 is started, and the rear wall 28 passes below the medicine feeding roll 72. Before that, the rotation of the medicine feeding roll 72 is stopped.
Therefore, the medicinal-effect-controlling insecticide 10 is not sprayed on both the front and rear sides of the seedling raising container 1 based on the transfer direction, thereby preventing the insecticide 10 from scattering from the seedling raising container 1. That is, the efficacy-controlling insecticide 10
Even if it is not sprayed on the entire surface of the seedling raising container 1, it is sufficient that the seedling is transplanted together with the floor soil 5 when transplanting to the field. Spraying to form a non-spraying area on each of the front and rear sides and left and right sides to prevent scattering, thereby eliminating the need for cumbersome disposal of flying chemicals, preventing the occurrence of chemical damage and the deterioration of the surrounding environment .
