Early repair of the whole tree crown has been picked for many years of tea, crown growth branches are generally relatively weak, because of the "chicken claws" more affect the supply of tea tree nutrients and the growth of new shoots. Therefore, it is necessary to carry out trimming before the germination of the spring buds from the startling to the spring equinox, and cut off the "chicken claw sticks" and "dry dead sticks" of the bonsai, and generally cut 5 to 7 cm. Severely chilled tea gardens should be re-pruned and cut to 8 to 10 cm. The young tea gardens are shaped and pruned, and the pruning and pruning are all necessary to smooth the tea tree crown, promote the neat germination, and balance growth. The first type of pruning is carried out when the tea seedlings are transplanted and planted, and the main branch is cut with a pruning shearer 15 to 20 cm from the ground. In the second year after planting, the second type of pruning is carried out in early March to early March. The height varies depending on the type of tea tree. Generally, it is cut at a level of 30 to 35 centimeters from the ground. A third cut was made in the spring of the third year after planting, and the height was 45 to 50 cm from the ground.
During the early application of germinating spring tea, new tea shoots grow vigorously, grow fast, consume relatively large amounts of nutrients, and have strong root absorption ability. The basal fertilizer alone in autumn last year could not meet the needs of spring shoot growth and could easily cause soil nutrients in tea gardens. "Disconnected." Therefore, a precipitating fertilizer should be applied. When the temperature is stable above 10°C and the tea tree roots begin to germinate, it is imperative to pay attention to the application of precipitating fertilizer before and after the convulsions (ie, 15 to 20 days before mining). The precipitating fertilizer is mainly composed of nitrogen, phosphorus and potassium compound fertilizers or quick-acting chemical fertilizers. It is applied around the roots of tea plants and accounts for 60% to 70% of the total fertilization for the whole year. In addition, in order to make the spring tea germinate neatly and increase the bud weight, the 0.3% potassium dihydrogen phosphate solution can be sprayed on the foliar before the germination of the spring bud to increase the yield of the spring tea.
In the early-middle-tilled pine soil tea garden, after a few months of rain and snow in the winter, the soil has been compacted. The early-middle-cultivated loose soil can loosen the soil, increase the soil temperature, and enhance the vitality of the tea tree roots, which is conducive to early germination of spring tea. The cultivating loose soil is generally carried out before and after the convulsions, especially in the areas with more rain in the spring, and care must be taken to prevent the loss of water and soil caused by loose soil in the tea plantation. At the same time, weeds and leaves will be turned into the soil in combination with cultivator to reduce the number of insect populations.
As early as ditching, the spring temperature gradually recovered and the rain gradually increased. At this time, if there is more water in the tea garden and the garden is wet, it is not conducive to the growth of the tea tree and affects the sprouting of the spring tea. Therefore, regardless of the land or slope of tea gardens, drainage should be drained as soon as possible to prevent waterlogging, so as not to root the tea tree roots water rot, ensure the normal growth of tea roots.
As early as the spring tea picking period for pest control pests, it is time for pests such as locusts, tea caterpillars, and black locust white locusts to step up and control the spraying of 20% cypermethrin 2000 to 3000 times before the Ching Ming. In the initial period.
Tea plantation spring pipe catch five early
The spring management of tea gardens directly affects the yield and economic benefits of spring tea. In order to seize the high quality and high yield of tea, promote the early sprouting of the tea tree, early mining, and increase the extraction and picking batches, the tea farmers should do “five earlyâ€.
