Manure

The Jiuban Family Farm in Shengzhou City has over 60 mu of tea gardens, with varieties including Wuniuzao, Longjing 43, Golden Bud, and Yuehuang No.1, mainly producing black tea. In 2021, they produced more than 2,000 catties of black tea, selling at an average price of 200 RMB per catty. Their products are well-received, which is mainly attributed to the following two aspects: Firstly, ecological planting. No chemical pesticides are used in the tea garden; instead, lime-sulfur mixture is applied in winter to seal the garden, and no chemical fertilizers are used, only pig manure that has been fermented is applied. Newly developed tea gardens do not use herbicides for weed control, allowing grasses and tea plants to coexist harmoniously. Pig manure is fermented in bags for 5-6 months before being applied to the soil. Secondly, a craftsman's approach to production. They have sought out masters of black tea production to improve themselves while continuously experimenting and exploring, summarizing a complete set of black tea processing techniques. They follow these established processes with dedication when making their tea. Good raw materials combined with meticulous production naturally result in high-quality products.

Tea gardens are characterized by a diverse range of weeds, complex weed communities, and strong stability. According to incomplete surveys and statistics, there are as many as 202 common weed species found in domestic tea gardens, belonging to 49 families and 163 genera. Weeds can impact the growth of tea plants, causing symptoms such as stunted growth, yellowing leaves, leaf drop, and delayed development. They may also carry diseases or pests that affect tea plants directly or act as intermediate hosts, indirectly impacting the growth and development of tea plants. "Grass to suppress grass" is an integral part of the green and efficient prevention and control technology system for Guizhou tea gardens, embodying the concept of "ecology at its root, agriculture at its core, and biological control first." Planting white clover in tea gardens can effectively suppress weeds and resist tea plant diseases and pests. Below are key technical points for reference.
