Check and Receive Guizhou’s Winter Management Techniques for Tea Gardens and Cold Prevention Measures
Great tea is grown, but it is also well-managed. As the saying goes: "One-third planting, two-thirds management." After three seasons of growth and harvesting in spring, summer, and autumn, the tea plant has expended a great deal of nutrients, and the soil between rows becomes compacted. As winter approaches, proper garden management becomes particularly important for the quality and yield of next year's tea leaves. For this reason, the Tea Industry Development Working Group, in collaboration with Guizhou Broadcasting Station's Ecology & Rural Channel, has produced a teaching video on tea garden management during autumn and winter for reference and learning by tea companies and farmers. The video received strong support from the Guizhou Tea Research Institute and covers four parts: fertilization principles and recommendations, pruning techniques for tea plants, pest and disease control, and cold prevention measures. 1 Winter Fertilization According to the growth and development patterns of tea plants, as they enter autumn and winter, the above-ground parts will gradually stop growing and enter dormancy. However, the underground parts become increasingly active and enter the peak period of root activity throughout the year. At this time, the plant's root system significantly strengthens its absorption capacity and has a… -
Specific Measures for Mechanical Tea Pruning
For tea trees of different ages, the methods of mechanical pruning vary. For young tea trees, the primary focus is on shaping pruning; for mature tea trees, light and deep pruning are predominant; and for old tea trees, rejuvenation pruning and stump cutting are mainly conducted. Generally, pruning around the time of Jingzhe (Awakening of Insects) yields good results. However, from an economic perspective, young tea trees should be pruned at the beginning of Lichun (Start of Spring), while other tea trees should be pruned after tea picking. Light Pruning Light pruning effectively promotes the sprouting and growth of tea buds. It also increases the density of productive branches, widens the tree canopy, and creates a favorable picking surface. For mature tea trees, light pruning should be conducted every two years, timed when the upper part of the tea tree stops growing. In regions prone to frost damage, pruning can be done half a month to one month before the spring sprouting of tea buds. For famous tea gardens, light pruning can be conducted after spring tea picking. During light pruning, hedging shears or pruning machines are primarily used to trim off about 4 cm of foliage and branches from… -
A Detailed Tutorial on Wuyi Rock Tea Refining Techniques by Intangible Cultural Heritage Practitioners, Highly Recommended for Collection!
Wuyi Rock Tea is a traditional Chinese tea renowned for its unique rock aroma and flavor, growing in the crevices of rocks. It is a semi-fermented green tea, with Dahongpao being one of its famous varieties. This article outlines the basic operational techniques and key points of each step in the refining process of Wuyi Rock Tea, aiming to provide guidance for production practice. Refining Techniques for Wuyi Rock Tea The refining of Wuyi Rock Tea involves processing raw tea into finished tea. The primary focus is to remove stems, fragments, and foreign matter, improve the uniformity and purity of the tea's appearance, and enhance its quality. The refining process comprises 13 steps: grading and sorting, preliminary sorting, sifting, cutting and shaping, winnowing (air selection), secondary sorting, blending, baking, cooling, packing (into boxes or barrels), storage, blending, additional baking, and packaging. Flow Chart of Wuyi Rock Tea Refining Process Grading and Sorting Grading and sorting are primarily for preparing raw tea for blending. Based on sensory evaluation results using the national standard samples or trade samples of Wuyi Rock Tea, raw teas are sorted according to their origin, variety, season, and quality. Specific steps for sorting raw tea: Samples are… -
Countermeasures for Low Temperature and Freezing Damage in Guizhou’s Spring Tea Gardens
Since February 22, most areas of our province, except some tea regions in Qiandongnan and Qiannan such as Qiannanwest, have suffered from a sudden drop in temperature and extreme weather conditions of low temperature and freezing. Preliminary investigations indicate that tea trees in various tea regions have shown varying degrees of symptoms of low-temperature stress, with more severe impacts in higher altitude tea gardens, leading to reduced yields or delayed picking. To mitigate the effects of low temperatures and freezing on spring tea, experts from the Tea Special Task Force, Guizhou Tea Research Institute, Zunyi Comprehensive Test Station of the National Tea Industry Technology System, and Guizhou Province Tea Industry Technology System have jointly studied and proposed the following remedial measures: 1. Timely and Moderate Pruning After temperatures stabilize, prune according to the degree of freezing damage to the tea plants, removing frozen branches and leaves promptly. Pruning should be carried out after the temperature rises and will not cause further serious freezing damage. The depth of pruning should vary depending on the severity of the freeze, ideally cutting 2-3 cm deeper than the dead tissue. For lightly frozen tea plants where only the edges of mature leaves or winter…- 3
