First, seed rice is sprinkled in a box with a nursery bed to germinate and grow to a certain size. The box used here is called a nursery box and is made according to a certain standard.

Next, seedlings grown to a certain size in a nursery box are planted in paddy fields after the rice has been raised. recent years,
Rice planting is mostly mechanized and done with rice planting machines,
The nursery box is made to have a predetermined size in consideration of mounting seedlings on the rice transplanter.

By the way, in the management of seedlings planted in a nursery box, a chemical agent for preventing mullet seedlings after germination is sprayed, or a granular chemical agent is sprayed just before transplantation to a paddy field to control pests. However, since the drug application to the nursery boxes is a relatively new method of drug application, it is the present situation that it is appropriately performed manually. The general procedure for spraying is to spray an appropriate amount of the drug onto the seedlings by hand, and then touch the tip of the seedling with a tool such as a brush to apply the drug to the seedlings. Drop it back. The seedlings are densely planted in the nursery box, so if you just apply the drug from the top, the drug will get on the leaves, or it will adhere to the leaves due to the large amount of water, and reach the seedling's source. This is because it is difficult.

[0005]

However, such drug spraying is not hygienic to the human body because the drug is handled by hand, and a predetermined small amount of drug must be sprayed evenly on the nursery boxes. Therefore, skill is required to accurately apply the drug, and the current situation is that the drug is not applied very accurately.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a powdery or granular material sprayer which can be easily and uniformly sprayed by a user without directly touching the drug. is there.
