Abstract

This research investigated opinions and future tasks about techniques for cherry trees maintenance by questionnaire survey to landscaping officials. As a result, it became clear that the techniques considered important especially were “pest control”, “pruning”, “soil improvement”, “replanting” and “fertilization”. For these techniques, it also became clear the opinions that “soil improvement” and “replanting” should be implemented on a regular or systematically and “pruning” and “fertilization” should be implemented on an as needed. Based on the results of testing for differences in opinions due to differences in attributes, we considered “pruning” has big differences in opinions, “replanting” and “fertilization” had differences in opinions, and “soil improvement” had no differences in opinions. As future issues about each technique, we considered the verification of methods and effects and the solving of the difference in opinion. And, the matters about each technique that are expected in the future were sharing implementation examples, technology development and accumulation of research results.
