Tea Tree Cultivation Techniques: How to Improve Tea Quality and Yield?
How to improve tea quality and yield? Please introduce the methods. To improve tea quality and yield, you can refer to the following methods: 1. Fertilization timing. When the new shoots of each round of tea leaves in spring, summer and autumn sprout and grow to the stage of one bud and one initial leaf, choose a windless sunny early morning, evening or cloudy day for spraying, once a week for 2 to 3 consecutive sprays. Spray until the leaf surface drips...
How to improve tea quality and yield? Please introduce the methods
To improve tea quality and yield, you can refer to the following methods:
I. Fertilization timing. When the new shoots of each round of tea leaves in spring, summer and autumn sprout and grow to the stage of one bud and one initial leaf, choose a windless sunny early morning, evening or cloudy day for spraying, once a week for 2 to 3 consecutive sprays. Spray until the leaf surface drips.
II. Fertilizer ratio. Mainly nitrogen, phosphorus and potassium, supplemented by trace-element fertilizers, with a ratio of 4:1:1. Trace-element fertilizers are proportioned according to the principle of supplementing whatever the tea tree lacks.
III. Fertilization concentration. The fertilization concentration is related to the fertilizer variety and weather conditions. According to experiments, urea is 0.5%, superphosphate 1%, potassium sulfate 0.5%, zinc sulfate 50 to 100 ppm, and ferric molybdate 20 to 50 ppm. If the concentration is too high, fertilizer burn is likely to occur; otherwise it will not be effective.
IV. Combining multiple operations. It can be combined with pest control, sprinkler irrigation and plant growth regulators, which saves labor and makes mechanized operation easier to achieve. Fertilizer and pesticide chemical properties. Acidic fertilizers should be matched with acidic pesticides, and alkaline fertilizers with alkaline pesticides, so as not to produce chemical reactions or precipitation, in order to prevent mutual cancellation of fertilizer and pesticide efficacy.
V. Use biological pesticides to control pests and diseases. Using biological pesticides to control tea tree pests and diseases is a safe, reliable, pollution-free and hazard-free option, and the best choice with low cost and high control efficacy, such as Bt emulsion, Bacillus thuringiensis preparations, Beauveria bassiana, agricultural antibiotics and plant antibiotics, etc.
