The best time for transplanting tea seedlings and how long to apply fertilizer after transplanting? How to trim management?

The better time for transplanting tea seedlings is from November to March of the second year, and if the weather is relatively cold, it can be postponed to February-March. Generally transplanting fertilizer for about one month, you can use ditch application method, ploughing wide ditches around the canopy between rows, spreading fertilizer on the ground first, and then turning into the ground. When the tea tree reaches 30cm, it will be pruned for the first time.

1. The best time to transplant tea seedlings

The best time for transplanting tea seedlings is from November to March of the second year, and if the weather is relatively cold, it can be postponed to February-March. It is necessary to water once before transplanting to keep the soil moist, and the seedlings can rise after 1-2 days. Bring more soil to prevent root damage. When transplanting, the tea seedlings should be placed upright, and then filled and compacted with soil.

2. How long to apply fertilizer after transplanting tea seedlings

The main results are as follows: 1. In general, spring tea fertilizer is applied after transplanting for about one month, and urea 15-20kg and potassium chloride 10-15kg are selected to apply fertilizer for 1-2 times, and then in summer and autumn, urea 10-15kg is applied for 1-2 times. The yield is higher than the upper limit, and the lower limit is lower. Green tea can apply more nitrogen fertilizer to improve quality.

2. Black tea should apply less nitrogen fertilizer to avoid fermentation inhibition, red soil tea garden is lack of phosphorus, more phosphorus fertilizer should be applied; if potassium deficiency is serious in southern soil, more potassium fertilizer can be applied, mature trees use more chloro-potassium, and young trees use less. Tea tree is a kind of deep-rooted plant, which goes deep into the soil layer more than 1m, and the root system is concentrated in the direction of perennial fertilization. Proper deep application can guide the root system to develop to the deep layer and increase the area of absorbing nutrients.

3. Ditch application method can be used to combine ploughing and opening wide ditches near the canopy between rows, fertilizers are first spread on the ground, and then turned into the ground, topdressing is the same as basic application, the depth of topdressing is 10-20cm, sand should be shallow, tea trees and fruit trees are mostly planted in hilly sloping land, especially in hilly sloping land, especially the soil layer is often thin and soil moisture is poor, fertilization should be applied a small number of times, that is, less each time, more times, and timely watering to avoid root burning.

Third, how to prune and manage tea trees

1. When the tea tree grows to 30cm, it will be pruned for the first time, generally cutting off the part above 15cm from the ground, leaving about 2-3 branches.

2. When the tea tree grows above 40cm again, it will be pruned for the second time, generally cutting off the main branches above 25cm from the ground.

3. The third pruning should be carried out when the tea tree grows above 55cm, generally cutting off the part above 35-40cm from the ground. When the tea tree grows above 55cm, it can be trimmed or trimmed appropriately. When the tea tree crown reaches above 70cm and the tree width reaches 1.3m, the tea garden can be put into production earlier.
