不同颜色棚膜对甜椒生物量积累及养分吸收分配的影响
Effects of Different Color Films on Biomass Accumulation, Nutrient Uptake and Distribution of Sweet Pepper
摘要
Abstract
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.关键词
