Intercropping

For Pu'er tea, many tea enthusiasts have the concept of "drink old tea, store new tea." So, how can we determine if a new tea has collection value? First, making a good tea requires many factors. The most critical are the following three aspects: What kind of new tea has the greatest collection value? I. Raw Materials Without good raw materials, no matter how skillful the process is or how correctly it's stored later, the tea cannot develop a good taste during its transformation later on. 1. Tea Variety A good tea is cultivated by people and is also the result of natural selection over thousands of years. Among various tea varieties, the sexual reproduction-based large-leaf type native to Yunnan is best suited for making Pu'er tea. 2. Growing Environment A suitable environment for growing tea trees. This includes appropriate altitude, proper sunlight duration and intensity, well-spaced planting, appropriate intercropping, no need for pesticides due to biodiversity that prevents the occurrence and development of diseases and pests, etc. 3. Picking Parts and Time Different parts of the tea leaves such as the bud tip, leaf, stalk, and yellow leaf play different roles in the post-fermentation process and have different effects…

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. White clover in tea gardens and pollinating insects - bees Intercropping white clover in tea gardens Effective "grass to suppress grass" In recent years, research teams from Guizhou University, the Provincial Plant Protection and Inspection Station, the Provincial Academy of Agricultural Sciences, and the Provincial Soil and Fertilizer…

To prevent drought damage in tea gardens and reduce losses in tea production, supplementary measures to replenish water and suppress evaporation can be taken before the onset of drought. These include irrigation to supplement water, loosening the soil and weeding, inter-row grass covering, etc., to maintain and regulate soil moisture and improve the microclimate around the tea plants, thereby enhancing the tea trees' drought resistance. Irrigation Replenishment Tea garden irrigation methods include furrow irrigation, sprinkler irrigation, drip irrigation, among others, each with its own advantages and disadvantages. Furrow irrigation is suitable for flat tea gardens and can quickly increase soil moisture levels, promptly rescuing drought-stressed tea trees, but it consumes a large amount of water, has a small impact on air humidity, and can lead to waste of water resources through surface runoff and deep seepage, as well as damaging some of the topsoil structure. Drip irrigation reduces evaporation and saves water, but it requires a higher initial investment and cannot effectively improve the microclimate of the tea garden. Therefore, in recent decades, sprinkler irrigation has been the primary method used for drought prevention and mitigation in tea gardens. Sprinkler Irrigation can not only increase soil moisture but also lower…
