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影响OA

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.
