I. Weeding and loosening soil: After 4-5 months of rain and snow in the tea garden, the soil has been knotted, and some have grown grass. At this time, the soil temperature is low. Therefore, before the spring tea mining, the tea garden weeding and loosening soil Conducive to loose soil, improve soil temperature, remove weeds, reduce water and nutrient consumption, and promote the early germination of spring tea. Weeding loose soil is generally carried out at the end of February and early March, and the depth is preferably 10-15 cm.

Second, the application of germination fertilizer: the application of germination time should be sooner rather than later, in the 15-20 cm from the root of the tea tree ditch application, 30-35 kg of urea or 30 kg of compound fertilizer or 2000-2500 kg of decomposed bar, Cover the soil after application. For tea gardens that cannot be ditched and fertilized, urea can be applied on rainy days, and the tea can be shaken with bamboo poles to let the fertilizer fall into the soil.
Third, pruning: pruning is best done at the end of February until the start of the horror, at the latest can not exceed March 10. Therefore, when the tea tree is dormant after a winter, the stems and roots store more nutrients, and it is easy to recover after pruning. In addition, the temperature rises in early spring, and the branches growing after pruning are not easy to be frozen, and the labor is not tight and easy to grasp. The production of tea gardens generally advocates light pruning, that is, generally cut off the autumn shoots (green stalks) last year, and keep the spring and summer shoots (red stalks), about 2 to 3 cm. If the canopy is frozen, it should be trimmed according to the degree of freezing. If the pruning is to be mastered, it should be kept deep, so as not to cut off some of the branches that can still germinate. For tea gardens that have not been frozen and picked up famous teas, the spring tea can be picked for spring tea and pruned after spring tea.
Fourth, anti-freeze: the weather is abnormal in early spring, the temperature is warm and cold, this climatic condition is extremely unfavorable for the production of high-grade famous tea in tea garden. In the early spring season, we should pay attention to the local weather forecast at any time, and take measures to prevent the cold in the early stage. After the release of the cold wave forecast, for the early-growing tea gardens that have sprouted leaves, it is necessary to concentrate on manpower to pick young sprouts to reduce the damage of freezing damage. In the Yingfengpo tea garden, which is vulnerable to frost damage, cover the tea towel surface with straw, weed or shade net, and cover the cover in time after the cold wave. After the tea tree has suffered from freezing damage, it must take corresponding care and rejuvenation measures according to the frozen condition, so that the tea tree can restore the tree as soon as possible.
5. Drainage in clearing ditch: In spring, there is much rain. If the tea garden is not well drained, the tea tree is susceptible to waterlogging, causing late growth and reduction of tea buds. 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.
Sixth, supplement leaf fertilizer: In early March, when the temperature exceeds 12 °C, the tea tree leaf absorption function can be utilized, and the roots can be supplemented with fertilizer to promote the early sprouting of the tea tree, increase the yield and improve the quality. External fertilization can be used with 0.5% urea, 0.3% potassium dihydrogen phosphate, multi-functional nutrient solution "ä¸èŒ¶æ—©" and hormone "920".
Seven, pest control: spring tea picking period, the initial value of aphids, tea caterpillars and black thorns and other pests, should be seized in the spring after the clearing, with 20% killing chrysanthemum 2000-3000 times liquid spray control.
