How Tea Garden Early Harvest High Quality and Yield
The technical content should enable the open-pit cultivation of Longjing tea to be harvested early, with high quality and high yield. At present, three technical measures can be taken in production management: Spray the root dressing. Foliage can be sprayed once every 7 to 10 days starting in late March. Farmers can choose to use high-quality potassium dihydrogen phosphate on the market, and apply foliar spray with 0.1 to 0.15 kg of potassium dihydrogen phosphate per 50 kg of water. The top-dressing fertilizer should be sprayed before 10 o'clock in the morning and after 3 o'clock in the afternoon. The reverse side of the tea should also be sprayed wet. 2. Spray "Chinese tea early". "In the tea early" can make Longjing tea early mining, high quality, high yield, is the ideal foliar fertilizer. The spraying time is generally 30 to 45 days before the normal spring tea production period of the local area. The tea garden in the greenhouse needs to be applied in advance. Each package needs to add 10 to 15 kilograms of water and spray on the foliage. 3. The use of green tea to produce special fertilizer "guarantee" microbial soil inoculants. After the inoculant is applied, the disease resistance and soil fertility of the tea tree can be improved and the picking period can be improved. Usage: 1 can be mixed with organic fertilizer, fine soil or plant ash for top dressing, basal use. 2 watered roots. 3 Before the transplanting, the young tea tree should be treated with basal fertilizer at 60 grams per mu, or with a suitable amount of water before the new shoot is sprouted. After 15 days, it should be applied once again. Four-year-old tea gardens fall in autumn and winter fertilizers are 40 to 60 grams per mu (organic tea gardens 60 to 80 grams/mu), and spring tea is topped with 40 to 60 grams per mu (organic tea gardens 60 to 80 grams/mu). Do not mix with fungicide. Tea experts warn tea farmers that it is necessary to use tea as early as possible and avoid the use of hormones such as phytotoxin and other pesticides. Blind use of such pesticides will increase the amount of pesticide residues and hormones in tea, thereby reducing the quality of tea, not worth the candle.
