Core Insights - The "Rice-Rice-Fungus" ecological circular agriculture model in Anren County, Hunan, effectively utilizes rice straw, transforming it from a burden into a valuable resource [1][2]. Group 1: Agricultural Practices - The model integrates rice production with edible mushroom cultivation, creating a closed-loop system that includes low stubble harvesting, mushroom cultivation for added value, and feed processing [2]. - Farmers in Datan Village are using crushed rice straw as a substrate for mushroom cultivation, which enhances growth due to its air permeability and nutritional value [2]. Group 2: Economic Benefits - A farmer reported an expected yield of 1,500 kilograms per mu (approximately 0.067 hectares) of mushrooms, with a net profit of about 20,000 yuan per mu [2]. - Another farmer highlighted that selling rice straw to cattle farms has generated an additional income of 10,000 yuan from 40 mu of rice fields [2]. - The comprehensive utilization of straw has broadened income channels for villagers, with nearly 2,000 mu of farmland in the village benefiting from this approach [2].
