Summer tea garden management technology

The growth conditions of light, heat and water in summer are appropriate, and the new shoots of tea trees grow vigorously. If the summer tea garden is neglected or poorly managed, it may cause abnormal physiological functions of tea tree growth, vigorous reproductive growth, excessive consumption of nutrients, directly affecting the yield of summer tea, and also have a significant impact on autumn tea and even spring tea production, causing autumn tea. Or the spring tea will be delayed in the coming year. Therefore, summer tea garden management should do the following work: Linyi Fertilizer Network Copyright

1. Pay attention to water retention and timely irrigation and drainage. In some summer and autumn, some tea areas often have persistent high temperature and low rainfall. Timely irrigation is conducive to maintaining the normal physiological metabolism of tea trees. The effect of increasing yield and quality is very obvious. The use of natural precipitation for water accumulation, water retention and water diversion from Tanggu canal is the main measure for water supply. Where conditions permit, the whole garden can be poured through the method of furrow irrigation or sprinkler irrigation to supplement the tea tree water to meet the growth needs. 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.

2, shallow tillage and weeding, chasing 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 tillage after harvesting, generally 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. At the same time, combined with foliar spray fertilizer 1-2 times to increase the yield of autumn tea. For the newly-built tea garden, the thin manure and excrement should be applied to the stalks of the tea seedlings, and a small amount of chemical nitrogen fertilizer should be infiltrated, which can not only moisturize the soil, but also strengthen the seedlings and seedlings.

3. Prevention and control of pests and diseases in tea gardens. 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
