桑基鱼塘陆面子系统物质循环利用研究进展

Research Progress of Material Recycling and Utilization in Mulberry-fish Pond Land Surface System

为揭示桑基鱼塘生态系统内部潜在的科学规律,从而促进桑基鱼塘的传承和保护。本文通过系统梳理桑基鱼塘陆面子系统的基本模式、物质来源与归趋、物质循环过程,通过分析桑叶的矿物元素和营养物质含量、桑树产量质量的影响因素、桑叶活性成分含量的影响因素、用桑量水平对蚕种产量质量的影响、蚕对桑叶营养物质消化率的影响因素来揭示桑叶对桑基鱼塘生态系统的影响特征。并通过分析蚕沙营养物质的分布特征、蚕沙对桑基鱼塘系统水质的影响、蚕沙的资源化利用,总结了蚕沙对桑基鱼塘生态系统的影响特征及资源化利用情况。通过分析池塘底泥的物质分布特征、堆肥对底泥理化性状的影响、底泥的资源化利用,综述了池塘底泥对陆面生态系统的影响。

In order to reveal the underlying scientific rules within the mulberry pond ecosystem,so as to promote the inheritance and protection of mulberry ponds.This article systematically combed the basic model,material source and fate,and material circulation process of the land surface subsystem of mulberry fish ponds,and analyzed the mineral elements and nutrient content of mulberry leaves,the influencing factors of mulberry yield and quality,and the content of active ingredients in mulberry leaves.The impact of the amount of mulberry used on the yield and quality of silkworm eggs,and the influencing factors of nutrients material digestibility of mulberry leaves by silkworms,revealed the characteristics of the impact of mulberry leaves on the mulberry fish pond ecosystem.By analyzing the distribution characteristics of nutrients in silkworm sand,the influence of silkworm sand on the water quality of mulberry pond system,and the resource utilization of silkworm sand,the influence characteristics and resource utilization of silkworm sand on mulberry pond ecosystem were summarized.Based on the analysis of the material distribution characteristics of pond sediment the influence of compost on the physicochemical properties of pond sediment the resource utilization of pond sediment on land ecosystem was summarized.
