水稻秸秆纤维育苗容器对柑橘幼苗生长的影响
Effect of Rice Straw Fiber Seedling Containers on the Growth of Citrus Seedlings
摘要
Abstract
To explore high-value utilization pathways for rice straw and to reduce microplastic pollution from plastic seedling containers,this study used rice straw pretreated with a choline chloride-monoethanolamine(ChCl-MEA)deep eutectic solvent(DES)as the fiber raw material.DES-recovered lignin,added at 15％of the soy protein isolate dry weight,was combined with the protein to form an adhesive.Seedling containers(MEA-15％)were then fabricated by a hot-pressing process.Using citrus(Satsuma mandarin)seedlings as the test crop,the performance of MEA-15％containers was compared with that of commercial pulp containers and polyethylene(PE)plastic containers in terms of seedling growth.The results showed that after a 60-day nursery period,plant height,stem diameter,aboveground dry weight,belowground dry weight,and root length of seedlings grown in MEA-15％containers were significantly greater than those in the pulp and plastic containers.Specifically,plant height reached 43.8 cm,which was 24.4％higher than in plastic containers;root length reached 40.3 cm,an increase of 38.0％;and the root-to-shoot ratio was 10.8％higher.The fibrous structure and appropriate wet mechanical properties of the MEA-15％containers allowed roots to naturally penetrate the walls of the containers,thereby avoiding root circling,while also improving the rhizosphere water environment and promoting seedling growth.This study provides technical support for the resource utilization of rice straw and for the development of environmentally friendly seedling containers.关键词
