On the eve of spring tea harvesting and listing, extreme weather is coming, how to manage the spring tea garden?
Effective disaster prevention measures should be actively taken in terms of strong winds, cooling, rainfall, snowfall, etc., to ensure the growth of spring tea and the smooth development of spring tea picking.
Pay close attention to the weather forecast, implement anti-freezing measures such as grass mulching between the rows of tea gardens and covering the tea tree canopy with grass curtains, films or shade nets before the arrival of the cold wave, and remove the tea tree canopy cover in time after the cold wave is over.
When the cold wave comes, irrigation or sprinkler irrigation can be used to reduce cold damage and frost damage.
Remove snow and ice ballast in a timely manner to reduce secondary disasters. Tea plantations with thick snow should be swept down in time to prevent the branches of the tea trees from being torn or crushed.
The cuttings nursery has the conditions to build an arch shed (greenhouse) covered with agricultural film, grass curtains, etc., and remove the snow in the shed in time according to the situation to prevent the nursery scaffolding from being crushed.
After the temperature returns to normal, prune the frozen tea garden in time, prune the light pruning with a light degree of frost damage, cut off the frozen dead branches and leaves, try to maintain the picking surface, and carry out deep pruning, heavy pruning or table mowing for the tea garden with a heavy degree of frost damage, and cut off the frozen branches.
Clean the ditch in time to keep the drainage smooth. After rain and snow, the tea garden should be cleaned and drained in time to prevent excessive precipitation and water accumulation after snow and frost melt from causing damage to the root system of tea trees and causing stains.
At the same time, do a good job in pre-harvest management such as cultivating and weeding and fertilization. In fine weather, remove weeds in time, top dressing and strengthen trees, keep the tea garden transparent, and increase the nutrient storage of tea trees.
