Early spring tea management methods are as follows:
First, weeding loose soil: After 4-5 months of rain and snow in the tea garden, the soil has been compacted, and some have grown grass. At this time, the soil temperature is low. Therefore, the tea plantation weeds the soil before the spring tea is mined. It helps to loosen the soil, increase the soil temperature, eliminate weeds, reduce the consumption of water and nutrients, and help promote the early germination of spring tea. The weeding and ripping are generally conducted at the end of February and early March, and the depth is preferably 10-15 cm.
Second, to promote germination fertilizer: the time to promote budding fertilizer should not be too late, in the 15-20 cm away from the roots of the tea tree to open the ditch applied, mu application of urea 30-35 kg or 30 kg of compound fertilizer or decomposed bar fertilizer 2000-2500 kg, Apply soil after application. For tea gardens that cannot be fertilized, it is possible to spread urea on rainy days and dip bamboo canopies to make fertilizers fall into the soil. 3. Pruning: Pruning is best done from the end of February to the time of convulsions, and not later than March 10. Therefore, after a winter dormant period, the tea trees have more nutrients stored in their stems and roots, and are easily restored after pruning. In addition, the temperature in early spring rises, and branches grown after pruning are not susceptible to freezing, and labor is not tense and easy to grasp. Production of tea gardens generally advocates light pruning, that is, generally cut last year's autumn shoots (green stems), stay in spring, summer shoots (red stems), cut about 2 to 3 centimeters. If the canopy is frozen, it should be pruned according to the degree of frost, and pruning should be done so that it is not too deep, so that the branches that still germinate are not cut. For those tea gardens that were not frozen and picked famous teas, the picking for early spring tea could be changed to pruning after the end of spring tea.
4. Antifreeze: In the early spring, the weather is abnormal, and the temperature is warm and cold. This climatic condition is extremely unfavorable to tea gardens producing high-quality and excellent tea. In the early spring season, local weather forecasts should always be taken care of, and measures to prevent late spring should be prepared in advance. After the release of the cold wave forecast, for early-cultivated tea gardens that have sprouted leaves, it is necessary to focus on ploughing young shoots to reduce the damage caused by freezing. In the windward slope tea gardens that are prone to frost damage, tea is covered with straw, weeds, or shade nets, and the cover is removed promptly after the cold wave. After the tea tree is chilled, it must take corresponding measures of care and rejuvenation according to the frozen conditions to restore the tree as soon as possible.
V. Drainage drainage: There is more rain in the spring. If the tea garden is not drained properly, the tea tree is susceptible to waterlogging and rot, resulting in delayed and reduced production of tea buds. Therefore, drainage should be drained in time, clearing and draining to ensure that the groundwater level is less than 1 meter, so that the rain stops the tea gardens from drying up and does not accumulate water.
Sixth, make-up foliar fertilizer: In early March, when the temperature exceeds 12°C, the absorption function of tea leaves can be utilized to supplement the fertilizing materials outside the roots to promote early sprouting of tea plants, increase yield, and improve quality. Root fertilization can be used 0.5% urea, 0.3% potassium dihydrogen phosphate, multi-nutrient solution "in tea early" and hormone "920" and so on.
VII. Control of Insect Pests: During the spring tea harvesting period, when pests such as aphids, tea caterpillars, and black locust are occurring, they should pay close attention to spraying and killing with 20% cypermethrin 2000-3000 times before Ching Ming after vernal equinox.
