Preventive Measures for the Tea Plant’s Late Spring Cold
During the spring warming period, cold air often invades, causing a significant drop in temperature. This weather, characterized by warmth before and cold after, is known as late spring cold. Late spring cold generally refers to prolonged periods of low temperatures and overcast rainy weather after the Vernal Equinox, specifically when the temperatures in late March or early April are lower than average. Depending on the timing, it can be further divided into "Vernal Equinox Cold" and "Qingming Cold." "Vernal Equinox Cold" occurs when the daily average temperature remains below 10°C for five days or more, with less than three hours of sunshine, from March 15 to March 27. "Qingming Cold" refers to low-temperature and rainy weather from March 28 to April 10. The Harm of Late Spring Cold to Tea Plants: In addition to variety, soil, fertilization, management, and processing skills, the production of high-quality tea also depends on climatic conditions. The relationship between tea production and temperature, sunlight, and rainfall is close. When the daily average temperature remains above 10°C for three consecutive days, tea buds begin to sprout and unfurl; once the temperature stabilizes above 10°C, the growth of buds and leaves accelerates, and new shoots emerge.…- 3

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… -

Processing Technology: The Manufacturing Process and Key Points of Dongting Mountain Biluochun Tea from Suzhou
Dongting Mountain Biluochun tea is one of the top ten famous teas in China, ranking alongside Longjing tea from West Lake. It is produced in Dongting Mountain (now Dongshan Town, Wuzhong District, Suzhou) and Xidongting Mountain (now Jinjing Town, Wuzhong District, on the West Hill Island of Taihu Lake, Suzhou). The tea groves and orchards are integrated, with tea plants interplanted among peach, plum, apricot, and loquat trees, representing a typical intercropping model of tea and fruit. The manufacturing process for Dongting Mountain Biluochun requires high standards, with premium-quality tea leaves needing to be handcrafted. The raw materials consist of the tender buds from a single bud and leaf at the initial stage of development from the local tea variety. Producing one pound of Dongting Mountain Biluochun requires 65,000 such buds, which are carefully processed through five steps: spreading, fixation, rolling, shaping, and baking. The finished Dongting Mountain Biluochun has a slender, tightly rolled shape resembling a snail, with visible bee legs, densely covered in white down, and a silvery-green hue with a hint of emerald. The infusion is bright yellowish-green, with a fresh aroma and prominent fruity fragrance. The taste is fresh and strong, with a noticeable fruity flavor.… -
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… -
Anhui Academy of Agricultural Sciences Tea Research Institute: Emergency Prevention and Remedial Techniques for Extreme Winter Cold Damage in Tea Gardens
Tea plant frost damage refers to the freezing injury that occurs when tea plants are exposed to temperatures below 0°C during the winter dormancy period. The parts of the tea plant most susceptible to frost damage are often the current year's shoots, flower buds, young fruits, and root necks. When a young shoot is slightly damaged by frost, only the pith of the branch may change color. With moderate frost damage, the xylem changes color, and severe frost damage can result in damage to the phloem. When the cambium layer changes color, the branch loses its ability to recover. Damage to the root neck can lead to weakened or complete death of the tea plant. 1. How is tea plant frost damage classified? What are the main symptoms? Frost damage can be categorized based on the cause into snow frost, wind frost, and frost. (1) Snow Frost. Snow damage is a common form of frost damage to tea plants, particularly in high-latitude and high-altitude tea gardens. Tea plants suffering from snow damage show branches broken under the weight of accumulated snow, as well as freezing injury due to alternating freeze-thaw cycles during melting periods, causing uneven temperature changes. In severe… -

Albino Tea Garden Cultivation and Soil Management Techniques
The main goal is to improve the soil condition, increase nutrient availability, and create favorable conditions for tea plant growth, with tasks including soil cultivation, weeding, fertilization, and moisture retention. I. Garden Cultivation Reasonable cultivation is an important measure to improve the soil condition in tea gardens, which can enhance the micro-ecological environment of the soil and provide good conditions for the growth and development of tea plants, improving their vigor. 1. Shallow Cultivation and Weeding The purpose of shallow cultivation in tea gardens is to remove weeds, loosen the surface soil, and improve the micro-ecological environment of the surface soil layer. The depth of shallow cultivation is generally around 5 cm, and it can be combined with top-dressing and soil mounding. It's also essential to clear weeds and brambles around the tea garden promptly. For young tea gardens that are not yet closed row, cultivation should be done whenever weeds appear, requiring six to seven weedings per year. Since the root system of young tea gardens does not penetrate deeply in the planting year, shallow cultivation before the high-temperature season should be done early to avoid drought immediately after cultivation. For mature tea gardens, cultivation is divided into spring,… -

Because the last tea we tasted has taken us into another context, jumping into ripe tea. I'm not saying that this is necessarily historical fact, but we can view ripe tea as an attempt to mimic aged tea. If we have the opportunity, we can taste some very old teas and find them excellent, but when you try to make something like that, you realize it would take a lifetime. In such a situation, can we use technical means to directly present certain aspects of aged… -
