Abstract

Bu çalışma, Antalya'da Akdeniz Üniversitesi Ziraat Fakültesi Araştırma
ve Uygulama Çiftliğinde açık tarla (756 m²) koşullarında
yürütülmüştür. Denemede gölgeleme materyali olarak % 40, % 55, % 75
ve % 95 gölgeleme oranlı 4 farklı yeşil ışık seçici ağ kullanılmıştır.
Araştırmada, ışık seçici ağların bazı radyometrik özellikleri (toplam ışınım ve
fotosentetik etkin ışınım (PAR)) belirlenmiştir. Çalışmada ağların ortam
mikroklimasına etkisini belirlemek için iç ortam hava sıcaklığı ile nem
değerleri uygun algılayıcılarla ölçülmüştür. Ağların bitki gelişimi üzerine
etkisini belirlemek amacıyla ışık seçici ağlar ve açık tarla koşullarında
domates bitkisi yetiştirilmiştir. Elde edilen bulgulara göre % 40
gölgeleme oranlı yeşil ağ toplam ışınım ve PAR bandında en yüksek geçirgenliği
göstermiştir.

Some radiometric properties of green coloured shade nettings and its effect on ambient microclimate and plant growth

Abstract

This study was conducted at the research and application farm of Faculty of Agriculture, Akdeniz University in Antalya under open field (756 m²) conditions. The green shade nettings with shade factor of 40%, 55%, 75% and 95% were used as shading material in this study. Some radiometric properties (the global radiation and photosynthetically active radiation (PAR)) of shade nettings were determined in this study. Environment conditions inside the shade nets were also investigated. The air temperature and relative humidity were measured by appropriate sensors. In order to determine the effect of nets on plant growth, tomato plants were grown in shade nets and in open field conditions. According to the results, 40% shading green net showed the highest transmittance in total radiation and PAR band.
