How can tea garden management improve tea quality

The quality of tea garden management has a direct impact on tea quality. Pruning in autumn and intensified fertilization in winter can increase tea yield. If you want to improve quality, you need to pay attention to pest management and picking. I introduce you to a small agricultural economy:

1. Strengthen winter fertilization

Apply sufficient base fertilizer in winter and increase nitrogen fertilizer to make full use of the spring effect of fertilizer to make high quality and high yield of spring tea. Nitrogen fertilizers are usually used as germination fertilizers before spring tea picking. Nitrogen fertilizers are not used in winter. According to relevant information, more than 80% of the nutrients required for spring tea, especially nitrogen nutrition, come from the nitrogen absorbed and stored by the tea tree last winter. Therefore, the application of sufficient fertilizer in winter is the basis for increasing the yield of spring tea, and the germination fertilizer before spring tea is harvested is less than 13% absorbed by the tea tree. Therefore, in order to improve the quality of spring tea, it is necessary to apply nitrogen fertilizer as a furrow application before picking spring tea, and extract a part of it and apply it in combination with base fertilizer in the winter of last year. In this way, on the basis of applying sufficient base fertilizer, a part of nitrogen fertilizer was added, and then a part of the nitrogen fertilizer was sprayed in spring, thereby improving the utilization rate of nitrogen fertilizer by spring tea and increasing the yield significantly.

2. Change the spring pruning to autumn pruning to promote early spring tea buds

Spring tea is lightly trimmed before picking, and the wounds on the tea tree are difficult to heal for a while, and the growth is inhibited, which delays the germination of the tea tree and reduces the germination point, which affects the output of spring tea, especially the output of high-end spring tea. Instead, it will be lightly pruned after the autumn tea is picked, and the tea tree will have plenty of time to heal the wounds and restore vitality, which can promote the early spring buds of the tea and the buds to grow fat, which is conducive to the production of high-end spring tea. Production practice proves that changing the light pruning before the spring tea picking to the light pruning after the autumn tea picking, the spring tea mining period can be 5-7 days earlier, and the spring tea production can be increased by more than 10%. After the autumn tea is harvested, it must be trimmed lightly, and it must be carried out after the ground of the tea tree stops growing.

3. Implement fine picking, pick when you see the bud, directly increase the output of high-grade tea

The traditional method of picking is that when the buds and leaves in the tea garden are 10% to 15%, the picking is started after the picking standard is reached, and the picking is carried out after a period of time. In order to increase the output of high-grade tea, it is necessary to break the traditional picking mode and implement delicate picking instead of “raising big picks”. Tea gardens are picked on a tour and produce as many high-end famous tea leaves as possible. This way, although the output of tea is lower than the previous coarse harvest, the output value and income are greatly increased.

4. Effectively comprehensively control diseases and insect pests

Tea gardens were cleared at the end of autumn and early winter and sprayed with a mixture of stone and sulfur to reduce the overwintering base of pests and diseases, and prevent early spring tea leafhoppers, tea aphids, and tea rulers from harming young shoots. If there are any pests, control them in a timely manner in combination with frequent mining to avoid pesticide control.

5. How to improve the quality of tea?

If the famous tea is contaminated, especially for export products, its output value and reputation will be seriously frustrated. In order to improve the quality and yield of tea, in addition to measures such as planting green manure in the tea garden, covering and moisturizing, applying sufficient farm manure after each harvest, and improving tea-making techniques, foliar fertilizers must be used skillfully. This is because less fertilizer is used and effective A fast, high-yield good method can generally increase output by 20% to 30%.

(1) Fertilization time

When spring, summer and autumn tea germination new shoots grow a bud and a leaf appear in the first exhibition, choose windless sunny morning, evening or cloudy days, spraying 2 to 3 times a week. Spray until the leaves drip. Fertilizer ratio. Nitrogen, phosphorus, and potassium are the main elements, supplemented by micro-fertilizers, with a ratio of 4: 1: 1. The proportion of micro-fertilizers is based on what the tea tree lacks.

(2) Fertilization concentration

Fertilizer concentration is related to fertilizer types and weather conditions. According to tests, urea is 0.5% and superphosphate is 1%. 0.5% potassium sulfate, 50-100 mg / L of zinc sulfate, and 20-50 mg / L of iron molybdate. If the concentration is too large, it is easy to produce fat, otherwise it will not be effective. Many things combine. It can be combined with insect control, sprinkler irrigation and plant growth regulators, which saves labor and facilitates mechanization of operation. Chemical properties of fertilizers and pesticides. Acidic fertilizers must be mixed with acidic pesticides, and alkaline fertilizers must be mixed with alkaline pesticides, so that no chemical reaction and precipitation will occur, so as to prevent the mutual effect of fertilizer and medicine. Use biological pesticides to control pests. The use of biological pesticides for tea tree diseases and insect pests is the best choice for safety, reliability, pollution-free and pollution-free, and low cost and high efficacy, such as Bt emulsion, penicillium, Beauveria bassiana, agricultural antibiotics and plant antibiotics.
