Tea tree antifreeze measures
After the tea tree is frozen, not only the physiological function is damaged, but also the annual output is affected. It also leads to bald branches or dead plants. The following measures should be taken to provide care.
1. Between-line coverage, smoke-flooding drive: available firewood, straw, turf, leaves, sawmilling, barnyardgrass, rice-wheat husks, straw, etc., before the soil is frozen and covered with tea gardens, about 1500-2000 kg of grass per mu, shop Grass can be used straw, weeds, pruned tea branches, etc.; when the temperature dropped to about 2 °C, according to the wind direction, topography, area set pile ignition, both against late frost and accumulation of fat.
2. Covering frost and strengthening fertilizer management: For young tea trees, shade can be used to cover the canopy before the low-temperature cold wave arrives, and plastic nets or straws or weeds can be covered with the shade net; or directly covered with straw. Tea bushes; Strengthen fertilizer management, apply basic fertilizer; Apply organic manure or NPK fertilizer, improve soil temperature and soil fertility; For tea gardens with lighter freezing injury and good picking surface, do not prune as much as possible. Keep picking surface. For those who suffer heavy damage, deep pruning or heavy pruning should be performed.
3. Shallow ploughing and fertilizing, and cultivating the canopy: After thawing, timely cultivating valerian in shallow depth in early spring. If the depth of permafrost is deep, 1% urea can also be used for extra-root dressing; after the spring tea is infested during freezing, it will be pruned at the same time. Spraying foliar fertilizer should be promptly applied; frozen tea leaves may be delayed for a while because of the frostbite of the upper leaves. Therefore, a large leaf should be left for the spring tea picking, and the summer and autumn teas should be picked as usual. This will not only help improve the canopy, but also use high-grade premium teas to reduce losses caused by freezing damage.
