Abstract
瓜類作物為澎湖地區重要之大宗蔬菜，本試驗之主要目的為探討無葉檉柳防風林下微氣候之變化及其對瓜類作物生產之影響，以建立農林混植模式之參考。經2001年秋作及2002年春作之試驗結果得知：微氣候之調查，無葉檉柳防風林下秋冬季氣溫比無防風之空曠地（CK）平均提高0.5他。對減少東北季風之肆虐效果更優，平均比空曠地減少風速72.4％。防風林下水分之蒸發量比空曠地減少35.9％。空氣中鹽霧之含量，在裡柳防風林下0.5公尺高度之處，比空曠地平均減少80.3%, 1.5公尺高度處，平均減少87.2%。在檉柳防風林下背風面2m、3.5m、5m、6.5m、8m及空曠地（CK）等定點測得之日射量及日照時數，均較空曠地（CK）低，但不同之距離間，以背風面5m處最優。秋作檉柳防風林下種植越瓜、稜角絲瓜及小胡瓜等，果實產量均比無防風之空曠地（CK）高；春作則以3m、4m、5m、6m、7m處較優，但2m、8m、9m處卻較空曠地（CK）差。
For protecting the production of gourd crops, which are important vegetables in Penhu area, Athel tamarisk was planted as windbreak purpose. The objectives of this study were to investigate the effects of Athel tamarisk windbreak on the microclimate and the production of gourd crops. The experiment results from 2001 to 2002 were summarized as follows. The average air temperature under the windbreak of AtheL tamarisk was 0.5 ℃ higher than that under the open field, and the wind speed and the amount of evaporation decreased 72.4% and 35.9%, respectively. The effect of windbreak on salt concentration of air varied depending upon the height above the gourd. At the height of 0.5 m, the average salt concentration decrease 80.3%, and it decreased 87.2% at the height of 1.5 m. On the leeward of Athel tamarisk windbreak, it was found that both solar radiation and sunshine hour per day were lower than that under the open field. Yields of gourd crops grown under the Athel tamarisk windbreak were increased than that grown under the open field in autumn season. In spring season, the yields were increased at the 3, 4, 5, 6 and 7 m from the windbreak, but were decreased at the 2, 8, and 9 m from the windbreak relative to those grown under the open field.
