摘　　要：分别以紫色、蓝色、红色和无色(对照)棚膜覆盖拱棚,在相近光强条件下,研究光质对甜椒生物量积累及养分吸收分配的影响。结果表明,红膜提高了甜椒干重,蓝膜则使之降低,紫膜和对照无差异;果实占总干物重的比例以红膜最高,根、茎和叶片比例则以蓝膜最高;甜椒植株各器官氮含量均以蓝膜最高,磷含量以紫膜最高,有色膜覆盖提高茎中钾含量,但对果实中磷、钾含量影响不大;红膜显著提高甜椒植株氮、磷、钾吸收总量,蓝膜降低了根系、叶片和果实中氮、磷、钾吸收总量以及果实的分配率,但增加了其在叶片中的分配率。Purple film, blue film, red film and colorless film (control) were used to study the biomass accumulation, nutrient uptake and distribution of sweet pepper. The results showed that red color film could increase the dry weight of sweet pepper while blue film made it decreased, the purple film and control treatment showed no difference;fruit accounted for the proportion of the dry biomass was highest under red film while the proportion of root, stem and leaf were largest under blue film; the nitrogen content in different organs of sweet pepper were the highest under blue films,phosphorus content in purple film was highest, different color films increased the potassium content in stem while showed no different of the phosphorus and potassium content in fruit; the total uptake quantity of nitrogen, phosphorus and potassium in different organs of sweet pepper were increased by red film and decreased the amount in root, leaf and fruit by blue film;blue film increased the fruit accounted for the proportion of the total uptake quantity of nitrogen, phosphorus and potassium in fruit while decreased it in leaf.
