Summer and autumn early management of spring tea in the coming year

The new shoots of summer and autumn tea trees grow vigorously. If the tea gardens are poorly managed or poorly managed, the physiological functions of tea trees may be abnormal, the reproductive growth is strong, and the nutrients are excessively consumed, which directly affects the yield of summer tea. It is also important for autumn tea and even spring tea production. The effect is that the autumn tea or the spring tea in the coming year will be delayed. Therefore, tea garden management should do the following work: Linyi Fertilizer Network Copyright

Pay attention to water conservation and timely irrigation and drainage. There are many ways to protect water. For example, cleaning, constructing a tea garden irrigation and drainage system, opening a water storage ditch pond, and planting grass between tea gardens are all conducive to reducing tea garden turbulence and increasing water storage. For tea gardens affected by waterlogging disasters, it is necessary to clear the ditch irrigation and drainage in time, strengthen the management of tea gardens, and pay close attention to repairing water-damaged tea gardens and slope-changing tea gardens, so as to complement roads, ditch and gardens. Especially in the newly-built tea garden, the tea seedlings are young, the roots are underdeveloped, and the plants are vulnerable to disasters, resulting in the lack of ridges and ridges. The most effective way to repair the irrigation and drainage ditch is to ensure that the garden is covered and covered, ensuring early planting, early production, early Effective.

Shallow tillage and weeding, and apply fertilizer. The tea garden soil is pressed and stamped by the spring, and the soil surface is generally solid, which affects the root activity of the tea tree. At the same time, as the temperature rises and the rain increases, the growth of weeds in the tea garden is accelerated, and at the same time, pests and diseases are also greatly increased. Therefore, after the end of spring tea, the loose soil should be shallowly ploughed and the weeds should be removed. Even if the herb garden is used, the spring tea should be combined with fertilization for shallow ploughing, usually 10~15 cm. Shallow ploughing can destroy the surface capillaries of the soil and reduce the evaporation of the lower layer of water, which can inhibit and reduce the growth of weeds, and loosen the topsoil, which has the effect of retaining water and drought in the summer tea garden. For young tea gardens, it is emphasized that the whole garden should be covered with grass, grass, water, straw, straw, etc., which will inhibit weed regeneration, reduce soil temperature and water evaporation, prevent flooding and soil erosion, and increase soil organic matter. All have significant functions, and should be vigorously promoted and applied. Generally, the mu covers about 1,000 kilograms. When the fertilizer is applied, it should be done without delay. The amount of topdressing before the autumn tea after summer tea should account for 20% of the topdressing fertilizer in the whole year. It is mainly based on quick-acting fertilizer. Generally, 20-30 kg of urea or 30-50 kg of compound fertilizer is applied per mu of mature tea garden, and the high-yield tea garden is appropriately increased. It is best to apply different tea special fertilizers. Linyi Fertilizer Network Copyright

Tea garden pest control. Implement the policy of “prevention first and comprehensive prevention”. Frequently remove weeds, keep the tea gardens ventilated and light; properly manage the drainage ditch to avoid water accumulation in the tea garden; carefully cut off the branches with pests and diseases when pruning; timely, batch and diligent mining can reduce the occurrence of pests and diseases. When pesticides are used for prevention and control, it is forbidden to use high-toxicity and high-residue pesticides, and to promote the use of biological pesticides and low-toxicity and low-residue pesticides. In order to ensure that the tea leaves are green and non-polluting, methods such as trapping and killing, artificial killing and removal should be actively promoted. And try to reduce the number of applications as much as possible. Promote high-efficiency, low-toxic, low-residue pesticides. Linyi Fertilizer Network Copyright

Properly trimmed. From the perspective of fresh leaf inclusions, the quality of summer tea is not as good as that of spring tea, and spring and autumn green tea is obviously superior to summer tea. The summer temperature is high, the rain is sufficient, the leaves mature quickly, the buds are easy to age, and the spring and summer tea gap period and the summer and autumn tea gap period can be properly trimmed to promote the germination of tea buds and improve the production of famous tea. It is necessary to pay attention to proper tenderness and combination of retention and maintenance. It can be harvested until mid-to-late September. If the drought is severe or the tree is weak, it should be less, and the park should be closed in advance. For young mining gardens, topping and retaining are the mainstays, supplemented by tenderness; for mature tea gardens, mainly for mining; for renewing tea gardens, for raising, combining and cultivating canopies.
