Summer and autumn are critical periods for tea garden management. Strengthening summer and autumn tea garden production management is the foundation for ensuring high-quality and high-yield summer and autumn tea and the following spring tea. The Planting Industry Management Department of the Ministry of Agriculture and Rural Affairs, together with the National Agricultural Technology Extension Service Center, the Expert Advisory Group for Tea of the Ministry of Agriculture and Rural Affairs, and the National Tea Industry Technology System, have developed the following technical guidance on summer and autumn tea garden production management and disaster prevention and mitigation. Strengthening Tea Garden Production Management (1) Tea Plant Pruning - For year-round harvesting tea gardens, promptly perform the initial light pruning after spring tea harvesting, cutting off the top 5-10 cm of shoots from the canopy. During summer tea harvesting, it is advisable to allow some growth retention and use the leaf-retention method or tip-picking method to maintain an appropriate leaf layer thickness. Harvesting should be appropriately stopped earlier in autumn to avoid affecting the yield and quality of the following year's spring tea. To cultivate a good picking surface, the second light pruning should be completed before mid-July, with the pruning height…

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…
