Group 1 - Shandong Province's Wudi County is actively developing the under-forest economy, promoting a model of combined planting and breeding, which enhances farmers' enthusiasm for forestry production and supports rural revitalization and sustainable development of the forestry industry [1] - The Zongwang Village's ecological breeding cooperative reports that the economic benefits of raising藏香猪 (藏香猪) are significant, with a single adult pig selling for up to 5000 yuan, and the cooperative has over 500藏香猪 and 200 wild藏香猪, generating an annual profit exceeding 800,000 yuan [1] - The cooperative's 20 acres of under-forest breeding base demonstrates a successful model for integrating agriculture and forestry, contributing to local economic growth [1] Group 2 - The natural breeding method for golden cicadas in Guojia Village shows a survival rate of 16% in the first year, three times higher than traditional methods, with a maximum yield of 10,000 yuan per acre, significantly surpassing traditional forestry planting returns [2] - The scale of golden cicada breeding in Guojia Village has reached 53 acres, involving 18 households, and has encouraged surrounding communities to engage in similar breeding activities [2] - Liu Xilin from Wuying Village has developed a method of "worm farming under trees" using cow dung, which processes 4,000 cubic meters of cow dung annually and produces 1,000 cubic meters of worm castings, achieving a comprehensive yield of 10,000 yuan per acre [2]

Core Viewpoint - The article discusses the efforts in Guangdong Province to enhance the efficiency of livestock waste treatment, aligning with national policies aimed at improving agricultural pollution management and promoting resource utilization of livestock manure [2][5][32]. Group 1: Technological Implementation - The Guangdong Provincial Rural Science and Technology Special Commissioner team, in collaboration with local agricultural institutions, is providing technical services to improve livestock waste management in Qingtan Town [3][4][30]. - The introduction of the "worm treatment" ecological purification model is highlighted as a key innovation, which offers advantages such as ease of operation, high efficiency, and product value addition [20][21]. Group 2: Current Challenges and Solutions - Qingtan Town's rapid livestock industry development faces challenges such as inadequate waste treatment facilities, leading to high discharge pressure and low resource utilization rates [9][10]. - The resource utilization rate of livestock waste is targeted to increase from 75% to 80.33% through the implementation of new technologies and systematic planning [14][15]. Group 3: Economic and Ecological Benefits - The worm treatment method can achieve a nitrogen removal rate of 75% and reduce the emissions of hydrogen sulfide and ammonia by 80-90%, thus providing both economic and ecological benefits [23][25]. - The establishment of a closed-loop system integrating chicken farming, worm cultivation, and organic fertilizer planting is being explored to enhance sustainability [26][30]. Group 4: Future Directions - The special commissioner team plans to continue monitoring the effectiveness of the worm treatment system and aims to develop replicable and scalable technical standards and management mechanisms [31][32]. - The initiative is positioned to support the green development of livestock farming and the prevention of agricultural pollution in Guangdong, contributing to rural revitalization and high-quality ecological agriculture [32][34].
