Hunan is a major tea-producing province. The current freezing rain and snow weather will cause damage (loss) to tea plantations, tea seedlings and tea area infrastructure. On February 5, the expert team of the cultivation post of the provincial tea industry technology system proposed anti-freezing remedies for tea gardens and nurseries for the reference of farmers.
For the production of tea gardens, before the arrival of cold air, cover the tea rows with straw in advance, and cover the tea tree canopy with straw, weeds or shade nets for the windward tea gardens that are prone to freezing. Spraying and irrigating water to the tea garden can alleviate the rate of soil temperature drop in the tea garden, increase the air humidity of the tea garden, and make the cold air not easy to invade. Clear the ditch and drain the water in time to prevent the snow accumulation, the water after freezing and thawing and the water from sprinkler irrigation from damaging the root system of the tea tree. Spray cold-proof antifreeze agent to enhance the cold and frost resistance of tea trees.
After the production of tea plantations encounters freezing rain and snow, the snow on the canopy is removed in time, and the dead branches are cut off, and early spring fertilizer is applied to make them re-branch. For the affected young tea plantations and replanting tea gardens, annual grain and dwarf cash crops can be interplanted between the rows to make up for the losses caused by the disaster. After the young tea trees in the newly planted tea garden freeze to death, the tea seedlings must be replanted in early spring.
For tea tree nurseries, cover with grass or other materials before the cold air arrives, and check and repair the covered film in time. After the frost breaks in spring and the temperature rises steadily, remove the mulch in time. Inspect and reinforce the scaffolding, and remove the ice or snow on the surface of the scaffolding in time to prevent freezing or snow from crushing the scaffolding. Pay attention to the water management of the nursery to prevent the dehydration of tea seedlings caused by the lifting of seedlings in frozen soil. For conditional seedling greenhouses, they can be properly heated in the shed to ensure that the tea nursery is not affected by low temperatures.
After freezing rain and snow, the tea nursery should clean the snow in time, clear the ditch and drain the water, and prevent the snow and water after freezing and thawing from causing damage to the root system of the tea seedlings. Clean up the seriously damaged nursery land in time, and tidy up the nursery box surface or re-cuttings according to the actual situation.
