Abstract:The Chinese government promotes the integration of crop cultivation and livestock breeding and onsite waste absorption to advance the green and sustainable development of agriculture. This paper takes Lüyuan Weipin Crop-Livestock Integrated Farm in Laiyang City as the research object, and conducts a comparative analysis with Laiyang City's data in the same period, using data from field surveys and soil/air quality tests. The study finds that the farm has developed a "dairy cow-biogas manure-crops, fruits and vegetables" planting-breeding circular model based on the hilly terrain and spatial characteristics. It has a stock of about 2,200 dairy cows, with a daily output of 33 tons of fresh milk and an annual output of 12,000 tons of manure, which meets 75% of the farm's fertilizer demand. The organic matter content in the cultivated soil has increased and stabilized at over 3%.Through spatial adaptation(i.e., optimizing the layout of functional zones based on terrain), the air quality rating has been improved to Grade I. By virtue of brand differentiation operation and channel coordination optimization,it has driven an annual comprehensive income of over 73 million yuan from crop cultivation, livestock breeding,processing and other sectors, forming an ecological circular agriculture model with the characteristics of hilly terrain, thereby providing a quantitative basis and practical reference for the promotion of planting-breeding circular agriculture in hilly areas.
