西北型日光温室内不同风速对甜瓜叶片光合、呼吸等生理指标的影响

Northwest Sunlight Greenhouse Different Wind Speed Equal to Only to the Muskmelon Leaves Photosynthesis, Respiration etc Physiological

试验以优选早蜜甜瓜为试材,研究了不同风速对甜瓜叶片光合、呼吸、蒸腾速率的影响规律。结果表明,从气孔导度来看:1.5 m/s时对甜瓜新叶生长最有利,0.7 m/s时对甜瓜老叶生长最有利;从胞间CO2浓度来看:0.7 m/s时对甜瓜新叶生长最有利,0.7 m/s时对甜瓜老叶生长最有利;从净光合速率来看:0.7 m/s时对甜瓜新叶生长最有利,0.9 m/s时对甜瓜老叶生长最有利;从蒸腾速率来看:0.5 m/s时对甜瓜新叶生长最有利,0.7 m/s时对甜瓜老叶生长最有利。鉴于0.7 m/s风速对实验中10项指标中的5项有利。因此:甜瓜温室栽培的风速应以0.7 m/s为宜。

Test is it try on material to regard early honey muskmelon of optimum seeking as, study different wind speed impact on the muskmelon blade is only shut, breathes, speed of transpiration law. The result indicates, according to leading degree in the air vent： Grow to muskmelon most favorable by new leaf at the 0.5m/s, Grow to muskmelon old Ye most favorable at the 0.7m/s; According to CO2 density among the afterbirth. Grow to muskmelon most favorable by new leaf at the 0. 7m/s, Grow to muskmelon old Ye most favorable at the 0.7m/s; Whether from net to shut speed is it think to come only： Grow to muskmelon most favorable by new leaf at the 0.7m/s, Grow to muskmelon old Ye most favorable at the 0.9m/s; According to speed of transpiration. Grow to muskmelon most favorable by new leaf at the 0.5m/s, Grow to muskmelon old Ye most favorable at the 0.7m/s. In view of 0. 7m/s wind speed is useful to five in ten indexes in the experiment. So： The wind speed of muskmelon greenhouse culture should be by 0. 7m/s should.
