“Spring tea mining early, raising the morning market, thus increasing the output value of spring tea production, is the key to the tea industry to increase efficiency and increase the income of tea farmers.†On February 7, in a group of tea fields in Jianxin Village, Lemon Village, Yilong County, Hu Wenjun, the stationmaster of the tea and fruit station of the County Agriculture and Animal Husbandry Bureau, is explaining the tea production management tips to the tea people. He said that in combination with Yilong and other tea production in the northeastern Sichuan region, the following six aspects of production management techniques are mainly used before the spring tea. The weeding and loosening tea gardens have been invaded by rain and snow for 4 to 5 months, and the soil has been consolidated. Growing grass, and the soil temperature is low at this time, therefore, weeding and loosening the tea garden before the spring tea mining is beneficial to loosening the soil, raising soil temperature, removing weeds, reducing water and nutrient consumption, and promoting spring tea. Early germination. Weeding loose soil is generally carried out from the end of February to the beginning of March, and the depth is preferably 10-15 cm.

The application of germination and fertilizer spring dressing is generally from early February to early March. Early germination should be applied early, and late buds should be applied late; Yangpo tea garden should be applied early, and Yinpo tea garden should be applied late. The amount of spring topdressing accounts for 60% of the annual topdressing amount. Generally, the adult-aged tea garden uses 30 kg of sulfur-containing compound fertilizer, 15 kg of urea, or 75 kg of “Zhongcha No.1†tea tree special fertilizer or 75 kg of tea organic fertilizer. . Young tea gardens have to be done a small number of times.
After applying the foliar fertilizer, when the temperature exceeds 12 °C, the absorption function of the tea leaves can be utilized, and the fertilizer can be applied outside the root to promote the early sprouting of the tea tree, increase the yield and improve the quality. Root fertilization can be used 0.5% urea, 0.3% potassium dihydrogen phosphate, medium tea early, green long, amino acid, fast harvest and so on. Foliar fertilizer spraying time is generally sprayed on the sunny day after 3 pm (on cloudy days), sprayed once every 7 days, and sprayed continuously for 2 to 3 times, the effect is better. . Spray should be even, especially on the tea tree, the middle leaf layer must be sprayed, it is best to spray both sides of the blade.
There is more rain in the spring in the clearing ditch. If the tea garden is not well drained, the tea tree is susceptible to waterlogging, causing late flowering and yield reduction. Therefore, it is necessary to drain the ditch in time, clear and clear the drainage ditch, and ensure that the groundwater level is below 1 m, so that the rain stops the tea garden and does not accumulate water.
Beware of "falling cold"
According to the situation in previous years, “cold spring cold†often occurs in the northeastern part of Sichuan, and it is very important to do a good job of “cold spring cold†prevention. Precaution:
(1) Picking in time. For the germinated tea buds, before the freezing damage, organize the personnel to pick up the tea in the mountains in time, and pick up the germinated buds as much as possible to reduce the loss.
(2) Tea plantation grass. About 1,500 to 2,000 kilograms of grass should be laid per acre, and the grass can be used to resist drought and freeze. The grass tea garden can be warmed by 1 to 2 °C than the grass garden, which can reduce the extent and depth of the frozen soil and maintain the soil moisture. Straw can be used for straw, weeds, trimmed tea branches, and the like.
(3) Smoke and smoke. The role of fumigation is to form smog in the tea garden space to prevent the radiation of heat from spreading. The "greenhouse effect" is used to prevent late frost. The effect is obvious. Before the night frost comes, the temperature will drop to about 2 °C, according to the wind direction, topography, The area is set to ignite, which prevents both late frost and accumulation of fertilizer.
(4) Covering frost protection. Before the cold wave is coming, cover the surface with a sunshade net, or cover the sunshade net with plastic film or straw or weeds; or cover the tea canopy directly with straw to protect the tea tree and enhance the resistance to frost.
(5) Strengthen the management of fertilizer culture, apply enough base fertilizer, and improve the anti-freezing ability of tea tree itself. Apply organic fertilizer or NPK fertilizer to improve soil temperature and soil fertility. However, it is not advisable to apply urea alone because the heat of absorption of urea will lower the temperature of the soil.
(6) Adding guest soil and thickening the living soil layer. Adding some new land excavated from the side of the hillside and around the tea garden, and adding it to the tea line properly, is beneficial to the heat preservation of the soil.
(7) Establish a protective forest belt at the windward entrance of the tea garden.
Early tea picking is generally carried out in time when more than 5% of the new buds in the spring awning reach the picking standard carried out by one bud and one leaf. It is necessary to collect in time and in batches in order to promote the continuous germination of spring tea, which is an effective measure for obtaining high quality and high efficiency of tea.
The pre-harvest management of spring tea in northeastern Sichuan has a trick to topdress before the beginning of March.
