Abstract

This study was carried out to investigate reduction of the frost damage using the mesh net used for the purpose of non-bagged cultivation. A device measuring the weight of frost was developed and installed in both the control and the experimental, and the effect of frost reduction was evaluated with their weights. As a result, weight of frost in the control was reduced from 37% to 59% with mesh net on the day the frost was observed. In addition, the device for automatically observing the amount of frost was developed and the height of the windbreak of the frost measuring device was determined to be 30 cm through wind tunnel experiment. The results of this study are expected to reduce frost damage during the flowering season of fruit trees by installing mesh net and it is expected to be used as basic data for agricultural use of mesh net.

본 연구에서는 서리의 피해 저감을 위하여 과수 무봉지 재배를 목적으로 사용하고 있는 그물망을 이용하고자, 서리의 양을 관측하는 장치를 대조구와 시험구에 설치하여 그 비교를 통해 서리 저감 효과를 구명하였다. 시험 결과 실제 서리가 관측된 날을 기준으로 시험구에서 37%에서 59%까지 저감 효과를 확인할 수 있었다. 또한 서리의 양을 자동으로 관측하는 장치를 개발하고 풍동실험을 통해 서리 측정 장치의 방풍함 높이를 30 cm로 결정하였다. 이러한 연구 결과는 그물망 설치함으로써 과수 개화기에 서리 피해를 저감할 수 있을 것으로 판단되며, 그물망의 농업적 이용에 대한 기초자료로 활용될 수 있을 것으로 기대된다.
