Abstract

This study was carried out to investigate at the micrometeorology change of the orchard according to the net installation. Two weather stations were installed at the inside of the anti-insect nets(2 mm, 4 mm), one was installed at the outside(control). They were observed the temperature, humidity, wind speed and solar radiation from April to September 2018. Daily mean temperature at the experimental group was higher than control group by 0.2°C. Daily mean humidity at the experimental group was higher than control group by 3.5 to 4.7%. Daily mean the solar radiation at the experimental group(2 mm) was lower than control group by 50%. The wind speed was decreased from 12% to 50% of the external wind speed at 4 mm, and from 25% to 59% at 2 mm.

본 연구는 방충망 시설이 생육환경에 미치는 영향을 구명하기 위한 기초자료로 활용되도록 무봉지 재배를 위 한 망 시설 테스트베드를 설치하고 온도, 습도, 풍속 및 일사량을 수집한 기상자료를 분석하여 망 시설 내·외부 의 미기상 특성을 확인하고자 하였으며, 기상자료를 분 석한 결과는 다음과 같다. 온도와 습도의 경우 망의 피 복 여부에 따라 0.2°C, 3.5~4.7%의 차이가 발생하였으며 실험구 대비 대조구에서 수분부족분이 증가하는 경향을 보였다. 외부와 망 시설 내부에서 일사 투과율은 격자 크기에 따라 큰 차이를 나타냈다. 특히 격자 크기가 2mm인 경우 외부와의 일사 투과율이 최대 50%정도까 지 감소하는 것으로 나타났으며, 이는 과실 생육에 큰 영향을 미칠 수 있기 때문에 격자 크기 선택에 있어서 고려해야할 요소로 판단된다. 태풍 솔릭 내습시의 망 시 설 내?외부의 풍속을 비교한 결과, 7 m/s이상의 고풍속 일 때 격자 크기가 4 mm 망 시설은 40% 이상, 2 mm 의 경우 50% 이상의 풍속 감소율을 보였다. 또한 풍속 저감 효과로 인한 낙과 피해도 현저하게 감소하는 것으 로 나타났다. 이러한 연구결과는 망 피복에 따른 과수의 생육환경에 미치는 영향과 최근에 잦은 이상기상 발생으 로 망 시설을 적용한 이상기상 피해저감 효과 등의 기 초자료로 활용될 수 있을 것으로 판단된다.
