Tea Garden

The “burnt pieces” in Pu'er raw tea are undesirable. However, this undesirability is not due to toxicity or harm to health but mainly affects the taste and appearance of the tea infusion. Theoretically, these “burnt pieces” can be avoided during the Pu'er tea production process; however, in practical application, they are almost impossible to avoid. The “burnt pieces” in Pu'er raw tea are essentially scorched tea juice that sticks to the iron wok and is not something dirty. During the process of fixing the fresh leaves, a large amount of water and tea juice overflow from the leaves, while the wok temperature is mostly above 200°C, which is very high. After several batches of fixing, a layer of tea juice forms on the surface of the iron wok, which is scorched black by the high heat and mixes with a small amount of the Pu'er tea material. We mentioned earlier that theoretically, “burnt pieces” can be avoided, and the most direct method would be to carefully clean the iron wok after each batch of fixing and before processing the next batch. If the scorched tea juice on the iron wok is completely washed off, it is theoretically possible to prevent…

Severe Infestation of Tea Looper How to Cope, Find Out Here It is currently late summer and early autumn, with cool weather in the morning and evening. This year has seen more rain than usual, resulting in vigorous growth of tea plants with lush green leaves, providing rich food for tea plant pests. According to investigations into the infestation of tea loopers in Longwu tea gardens, various age groups of larvae coexist, with severe overlapping generations. In some severely affected areas of tea gardens, the older leaves have been completely consumed, affecting the growth of tea plants, which requires close attention from tea garden managers. Due to differences in cultivation and management practices among individual households, the timing of infestations and the degree of damage vary across different tea gardens, making pest control challenging. It is essential to strengthen pest monitoring through field observations and the use of trapping devices, promptly understanding the dynamics of pest outbreaks and implementing appropriate measures: 1. Turn on insect-killing lamps, taking advantage of the fact that adult tea loopers are most active between 8:00 PM and 10:00 PM. Set the operating times of the lamps accordingly, ideally using a light-controlled mode where they automatically…

Main pests in autumn tea gardens and their control measures. The weather gradually cools down in September, with vigorous growth of tea plants and abundant food for pests, which is very conducive to the occurrence of pests such as mites and tea green leafhoppers. If not controlled in time, they can easily cause outbreaks that severely impact the yield and quality of next year's spring tea. The main pests occurring currently and their control measures are as follows: I. Tea Orange Spider Mite This pest is small in size, with adult and juvenile mites piercing and sucking tea plant sap. When mite numbers are low, the damage is not obvious and hard to detect. However, when mite numbers increase, the veins of affected leaves turn red, the leaves lose their green color and luster. Severe infestations result in a brown rust appearance on the underside of the leaves, withered and dried shoots and leaves, and a scorched appearance, and may even cause defoliation. Some tea gardens have experienced heavy infestations recently. Without effective control measures, mite populations will continue to rise. The following measures are recommended for control: 1. Strengthen garden management by removing weeds and fallen leaves. Timely picking…

According to the Rizhao City Meteorological Bureau's cold snap blue warning notice, affected by strong cold air, our city is expected to experience a cold snap from December 24th to 26th, with a temperature drop of 8-10°C. The lowest temperatures will occur on the morning of the 26th, with inland areas reaching around -10°C and coastal areas -8°C. On the 24th, daytime and nighttime northerly winds will strengthen to 5-6 on land, with gusts up to 8, gradually weakening on the 25th. Additionally, there will be sleet turning into light snow, with some areas experiencing moderate snow, from the daytime of the 24th through the night. Due to the significant temperature drop and low temperatures accompanied by light to moderate snow, there may be noticeable frost and snow damage, which could adversely affect tea plants overwintering in our city. To mitigate the impact of extreme weather on tea plants, the City Agricultural Technology Service Center has formulated technical guidance for tea gardens dealing with extreme weather. I. General Strategy for Winter Protection in Tea Gardens During Extreme Weather In the event of strong winds, heavy snow, and drastic temperature drops, timely winter protection measures should be taken for tea gardens.…

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…
