Core Viewpoint - The article discusses the innovative practices in green agriculture being explored in Huizhou, Guangdong, focusing on the promotion of green manure as a means to enhance soil health and sustainable agricultural development [2][3][5]. Group 1: Green Manure Promotion - Guangdong has been actively promoting the cultivation of green manure crops like purple vetch to ensure food security and support ecological civilization [2][3]. - A joint research team from the Guangdong Agricultural Environment and Soil Quality Protection Center and local agricultural departments conducted a study on winter green manure planting and green farming practices in Huizhou [4][5][12]. - The research aims to summarize experiences and innovate industry models to provide a "Huizhou experience" for the province's agricultural green transformation [7][8]. Group 2: Three-Wheel Drive Approach - Huizhou is advancing green manure cultivation through a "three-wheel drive" approach, focusing on system innovation, seed source conservation, and model exploration [8][51]. - The city has established a four-level agricultural technology service system to support green manure promotion, integrating expert guidance and local talent [30][31]. - By 2025, the area planted with purple vetch in Huizhou is expected to reach nearly 12,000 acres, marking a significant increase [32][33]. Group 3: Technical Models for Green Manure - Huizhou has developed three clear and feasible pathways for green manure promotion, including the "rice-rice-manure" model, which can reduce nitrogen fertilizer use by 10%-30% and increase rice yield by approximately 80 pounds per acre [39][40]. - The "fruit and tea garden intercropping" model utilizes summer and winter green manure varieties to maintain soil health and improve crop quality [43][45]. - The "rapid soil improvement" model targets newly cultivated and degraded lands, using fast-growing green manure varieties to enhance soil organic matter and structure [48][50]. Group 4: Future Directions - The research team emphasized the need to strengthen the three-level linkage mechanism to enhance the breeding of superior green manure varieties and conserve local genetic resources [54][55]. - Huizhou aims to deepen the integration of green manure planting with green farming practices, providing replicable experiences for the province's agricultural green development [59][60]. - The ongoing transformation of the green manure industry from merely "soil nurturing" to "wealth generation" reflects a significant shift in agricultural practices in Guangdong [63][65].

Core Viewpoint - The development of the purple cloud pea industry in Xinyang, Henan Province, is significantly enhancing farmers' income and promoting rural revitalization through various agricultural collaborations and innovative practices [1][2]. Group 1: Industry Development - The collaboration between the Henan Academy of Agricultural Sciences, the Xinyang Academy of Agricultural Sciences, and local governments is driving the growth of the purple cloud pea industry, leading to the development of various agricultural combinations such as "purple cloud pea + rice" and "purple cloud pea + tourism" [1]. - The planting area of purple cloud pea in Xinyang has stabilized at over 1.2 million acres, indicating a robust and sustainable agricultural practice [1]. Group 2: Economic Benefits - Farmers like Zhu Guanchun report that one box of honey produced from purple cloud pea can yield over 10 kilograms, selling for 40 yuan per kilogram, resulting in substantial income [1]. - Chen Guiquan, a large-scale farmer, has observed increased yields and improved quality of wheat, rice, and rapeseed due to the cultivation of purple cloud pea, which reduces the need for chemical fertilizers and pesticides [1]. Group 3: Environmental Impact - The purple cloud pea's ability to enhance soil fertility is attributed to its root nodules, which act as nitrogen-fixing agents, thereby reducing the need for chemical fertilizers and improving crop yields [1]. - Wang Mingjian, a fruit grower, has successfully used purple cloud pea to suppress weed growth, significantly lowering his weeding costs from 500 yuan per acre annually [2]. Group 4: Policy Support - Local governments in Xinyang are implementing various measures to promote the planting of green fertilizers like purple cloud pea, including financial incentives for crop rotation practices [2]. - The establishment of demonstration bases and the recognition of counties like Luoshan as key technology demonstration areas for green fertilizer indicate strong governmental support for the industry [2].
