一、模式简要概述 “稻——沼——蟹”能源生态模式是根据稻田养蟹稻蟹共生期间不能施肥治虫的要求,从延长生物链条,使各链条间的能量流动更趋合理的思路出发,通过生产试验总结出来的一种新的生态农业模式。该模式以大田为载体,通过沼肥施用和沼液喷施防病治虫技术、稻田养蟹技术等的运用,一方面使沼液中的有机质肥料促进稻田中的浮游微生
First, a brief overview of the model “rice - Marsh - Crab” energy ecological model is based on rice crabs can not be fertilized during rice crab symbiosis requirements, from extending the biological chain, the energy flow between the chain more reasonable thinking , A new eco-agriculture model summarized by the production experiment. This model uses field as the carrier, through the application of biogas fertilizer and biogas slurry spraying and disease prevention and control technology, rice crab technology and other applications, on the one hand make the organic fertilizer in the biogas slurry to promote planktonic microbes in the paddy field
