Early summer and early morning management of spring tea is good
The growth of tea shoots in summer and autumn is strong. If the tea gardens are poorly managed or poorly managed, it may cause abnormal growth and physiological functions of tea trees, vigorous reproductive growth, and excessive consumption of nutrients, directly affecting the yield of summer tea. It also has a significant impact on autumn tea and even the output of spring tea in the coming year. The influence caused autumn tea or late spring tea to occur less frequently. Therefore, tea garden management must do the following tasks: Pay attention to water conservation and timely irrigation and drainage. There are many ways to preserve water, such as cleaning, building irrigation systems for tea gardens, building water storage ditch pools, and paving between tea gardens to help reduce turbulence and increase water storage. For the tea gardens affected by waterlogging, it is imperative to clear the gutters and irrigation in time, strengthen the management of tea gardens, and urgently repair the water destroyed tea gardens and the slopes into the tea gardens so that roads, ditches and gardens can be matched. In particular, new tea gardens, young tea plants, undeveloped root systems, and susceptibility to culprits due to susceptibility to death caused by catastrophic death, should be timely repaired and drained. The most effective way is to cover the whole park and ensure early gardening, early production and early production. Effective. Weeding and weeding, chase fertilizer. After the tea garden soil is stamped and pressed by the spring, the surface of the soil is generally firm, affecting the root activity of the tea plant. At the same time, as the temperature rises and rain increases, the growth of weeds in the tea garden is accelerated, and at the same time, a large number of pests and diseases can also be bred. Therefore, after the spring tea is over, the soil should be ploughed loose and the weeds should be eradicated. Even if herbicides are used in the tea plantations, after the spring tea is harvested, it is necessary to combine shallow ploughing with fertilization. Usually, it is appropriate to use 10-15 cm. Shallow ploughing can destroy the capillary in the surface layer of the soil and reduce the evaporation of the lower layer of water. It can not only suppress and reduce the growth of weeds, but also loosen the topsoil, which has water-retaining and drought-resistance effects on summer tea gardens. For young tea gardens, it is emphasized that as much as possible, beech grass, pond grass, straw, straw, etc. should be covered in the whole park to prevent 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. The general mu covers about 1,000 kilograms. The fertilization should be applied as early as possible. The amount of topdressing before the autumn tea after the summer tea should account for 20% of the top dressing in the whole year, and the quick-acting fertilizer is the mainstay. Usually, 30 to 50 kg of urea or 30 to 50 kg of compound fertilizer is topdressed per acre of tea plantation, and the amount of high-yield tea plantation is increased appropriately. It is best to use different special fertilizers for tea. Tea plant pest control. Implement the principle of "prevention first, comprehensive prevention and control". Weeds are often used to keep the tea gardens airy and clear; we should properly drain the drains to avoid water accumulation in the tea gardens; we must carefully cut off branches with pests and diseases during the trimming period; timely, batch, and diligent harvesting can reduce the occurrence of pests and diseases. In the prevention and control of pesticides, the use of highly toxic and high-residue pesticides is prohibited, and the use of biological pesticides and low-toxicity and low-residue pesticides is advocated. In order to ensure that the tea leaves are green and free from pollution, methods such as trapping and killing, and manual killing and removal should be actively promoted. And do your best to reduce the number of applications. Promote efficient, low toxicity, low residue pesticides. Properly trimmed. From the perspective of the content of fresh leaves, 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. Summer high temperatures, adequate rainfall, rapid leaf maturation, easy to aging shoots, spring and summer tea gap and the appropriate trim between the summer and autumn tea gap can promote tea bud germination, and improve the production of famous tea. Should pay attention to appropriate tender mining, retention and integration, can be taken until mid-September, if severe drought or weak tree vigor should be less mining, early garden closure. For young-age harvesting gardens, the use of top-covering and re-cultivation are mainly supplemented by tender mining; the adult tea gardens are mainly harvested; the tea gardens are rejuvenated, and the cultivation is mainly adopted, and the tree crowns are collected and cultivated.
