摘　　要：为获得西瓜皮基碳气凝胶及西瓜皮基碳气凝胶新型肥对生菜品种大速生生长及营养指标的最佳添加量,以西瓜皮为材料,制备出西瓜皮基碳气凝胶及西瓜皮基碳气凝胶新型肥,研究不同比例碳气凝胶及新型肥的添加量对大速生植株株高、叶面积、叶片数、茎粗、根长、叶绿素含量等生长指标和鲜质量、可溶性糖、蛋白质、维生素C含量等营养品质指标的影响,进而筛选出碳气凝胶及新型肥促进大速生生长发育的最佳添加量。结果表明:施用西瓜皮基碳气凝胶和西瓜皮基碳气凝胶新型肥均可以促进大速生的生长发育,其中以添加4%西瓜皮基碳气凝胶和6%西瓜皮基碳气凝胶新型肥效果最好。本研究不仅可以提高西瓜皮的利用率,有效解决因西瓜皮丢弃、堆砌带来的环境污染问题,而且能降低化肥使用量,提高大速生的产量和营养品质,为西瓜皮基碳气凝胶新型肥对大速生生长发育的影响提供理论基础和参考。In order to obtain the best effect of watermelon peel-based carbon aerogels and watermelon peel-based carbon aerogels new fertilizer on the growth and nutritional indexes of lettuce variety Da Susheng,watermelon peel-based carbon aerogels new fertilizer were prepared by using watermelon rind as carbon source.The effects of different proportions of carbon aerogels and new fertilizer on the growth indexes such as plant height,leaf area,leaf number,stem diameter,root length and fresh weight and the nutritional quality indexes such as chlorophyll,soluble sugar,protein and vitamin C content of Da Susheng plants were studied,and then the optimal proportion of carbon aerogels and new fertilizer to promote the growth and development of Da Susheng was screened.The results showed that the application of watermelon peel-based carbon aerogels and watermelon peel-based carbon aerogels new fertilizer could promote the growth and development of Da Susheng,in which 4%watermelon peel-based carbon aerogels and 6%watermelon peel-based carbon aerogels new fertilizer had the best effect.This experiment could not only improve the utilization rate of watermelon peel,effectively solve the environmental pollution problems caused by the discarding and piling of watermelon peel,but also reduce the amount of chemical fertilizer used,improve the yield and nutritional quality of Da Susheng,and provide theoretical basis and reference for the effect of watermelon peel-based carbon aerogels new fertilizer on the growth and development of Da Susheng.
