Abstract
Tarımda çevre koşullarına bağlı olmadan bazı sebzelerde ve meyvelerde en fazla ürün artışı, seralarda ya da örtü altlarında sağlanabilir. Tekirdağ, Trakya Bölgesinde tarımsal üretimin yoğun bir şekilde yapıldığı illerin başında gelmektedir. Bu tarımsal üretim kollarından biri de, son yıllarda hızlı bir gelişme gösteren örtü altı yetiştiriciliğidir. Özellikle gelişimi hızlanan bu üretim şeklinde Tekirdağ ilinin, ikliminin Trakya'da daha ılıman ve İstanbul gibi büyük bir tüketim merkezine yakın olmasının büyük payı vardır. Bu çalışmada, Tekirdağ ilinde yapılan örtü altı yetiştiriciliğinde hava hareketinin, tünel içi sıcaklığına ve nemine olan etkileri araştırılmıştır. Gotik yapılı yüksek tünellerde yapılan doğal havalandırmada, yan havalandırma ve önarka kapı havalandırmalarının ilkbaharın ilk aylarında optimum değerler arasında kalmasına rağmen daha sonraki aylarda yetersiz olduğu bulunmuştur. Bu durum çatı kısmına yapılacak mahya havalandırması ile giderilebilir.
The highest product increase in some vegetables and fruits in terms of agriculture independent from environmental conditions may be ensured in greenhouses. Tekirdag is one of the primary cities in the Thrace Region where agricultural production is performed intensively. One of the branches of such agricultural production is greenhouse production which has recorded a rapid development in recent years. Moderate climate of Tekirdag observed in Thrace and the city's closeness to such a large consumption centre as Istanbul play a significant role in this production method whose development has particularly accelerated. In this study, the effects of the air movement were investigated on in-tunnel temperature and humidity on protected cultivation performed in Tekirdag province. Despite having optimum values in the first months of spring at gothic high tunnels with natural ventilation at the front-rear door and side air vent, it was found to be insufficient in the subsequent months. This situation will be rectified with a portion of the roof ridge vent.
