Liquid agent spraying method and liquid agent spraying device in tea garden

摘要

PROBLEM TO BE SOLVED: To develop a novel liquid agent spraying method and liquid agent spraying device capable of effectively acting a liquid agent (chemical solution) on the back of tea leaves, for example, in insect prevention and epidemic prevention work. SOLUTION: The liquid agent spraying device 1 of the present invention includes a liquid agent spraying machine 3 and a support 2 attached so that the liquid agent spraying machine 3 can be moved, of which the liquid agent spraying machine 3 is a tea ridge crown surface layer. A spraying means 31 having a spraying body 313 that rotates while in contact with the portion, and a liquid agent supply unit 32 that supplies the liquid agent L to the spraying means 31 or the upper surface of the tea ridges are provided, and the liquid agent L is supplied from the liquid agent supply unit 32 while spraying. The spraying main body 313 of the means 31 is rotated and contacted with respect to the work progress direction so as to stroke the tea leaves A on the ridges from behind, and the liquid agent L is sprayed on the tea ridges T to fertilize and prevent insects from the target tea ridges T. It is characterized by performing. [Selection diagram] Fig. 1
