摘要: 对上海现代化温室番茄整个生育期的营养液管理调查表明 ,番茄灌溉营养液的pH范围为 5 .0~ 6 .0 ,回收液pH范围为 6 .0~ 7.0 ;回收液EC值比灌溉液平均高约 1.0ms·cm-1,两者浓度在整个生育期变化不大 ;影响灌溉量的主要因素是温度、光照 ,回收液量占灌溉量的 4 0 %以上 ;营养液配方在不同生长期略有差别 ,营养生长期需氮、钙、镁高 ,生殖生长期需钾多 ,钙镁需求降低

Abstract: The investigation on the nutrient solution management of tomato cultivation under modern greenhouse showed that ranges of pH in nutrient solution and drainage solution were 5.0-6.0 and 6.0-7.0 respectively. The EC value in drainage solution was 1.0ms·cm -1 higher than that in nutrient solution. The important factors affecting the amount of nutrient solution supply were light intensity and temperature. The amount of drainage was over 40% of irrigation amount. Tomato needed more N,Ca and Mg during vegeta...
