The Luojiaqiao Vegetable Supply Base in Qingzhen City, Guizhou Province, has developed into a model of agricultural modernization, covering over 3,200 acres and producing over 8,000 tons of high-quality vegetables annually. It has established 8 experimental greenhouses to test and select suitable vegetable varieties for the local conditions, introducing over 700 varieties and shortlisting 300 for trial planting. The base employs around 13,000 laborers monthly, generating over 1.3 million yuan in daily labor wages and providing a stable annual income of over 30,000 yuan for more than 300 rural households. Leveraging big data and smart agriculture technologies, it ensures precise control of planting environments and quality, and employs professional planting masters for standardized farming. The base also implements an 'order-to-order production' model and has a sorting center for quick delivery of fresh produce to cities like Guiyang, Shenzhen, Hong Kong, and Macau, registering the 'Guishan Vegetables' trademark under the village economic cooperative.
