Cultivation techniques of tea seedlings

Do you know what the cultivation techniques of tea seedlings are? Next, let's talk to you about it by the editor of Tuliu.com.

1. Land preparation and trenching

The main results are as follows: (1) to open the planting ditch and select the suitable plot (the pH value is between 5.5 and 6.5) to flatten the garden. The double-line cutting specification has a large line spacing of 120 cm and a small line spacing of 33 cm. The distance between clusters is 30 cm. The planting ditch is 50 cm wide and 50 cm deep, and the bottom layer is 10 cm loose. When opening the ditch, it is required to pile the topsoil and the subsoil separately, and when backfilling, the topsoil is buried in the bottom, and the subsoil is placed on the surface. The planting specifications of single-row strip planting are row spacing 110 cm, cluster spacing 33 cm; planting ditch: 30 cm wide, 50 cm deep, and the bottom layer is 10 cm loose.

(2) sufficient base fertilizer should be applied in the ditch after the planting ditch has been opened. The bottom layer (1 mu = 667 square meters, the same below) is 1000-1500 kg of weeds or fence dung, 20 cm of soil cover, mix well with the soil, and then cover 10 cm of soil, and then apply the second layer of bottom fertilizer, 100 kg of cake fertilizer per mu plus 100 kg of tea tree special fertilizer, and finally backfill 20 cm of pure soil. after loosening the soil for a period of time and sinking, it will leave a concave groove 15-20 cm deep, waiting to be planted.

2. Tea seedling planting

The main results are as follows: (1) the tea seedlings are classified according to their size and planted respectively.

(2) in the original concave trench, two shallow planting ditches with a depth of 10 cm were opened first, and then the tea seedlings were staggered and arranged in the planting ditch according to the shape of "taste". There were 2 plants in each clump to straighten the tea seedlings and straighten the root system.

(3) cover the soil to the mud door firmly, pour enough water to fix the root, apply fertilizer (tea tree special fertilizer or compound fertilizer) 5 cm away from the root of the tea seedling, and then cover the soil to more than 5 cm above the mud door.

(4) after planting, the tea seedlings should be shaped and pruned at 15 cm from the ground in order to reduce the evaporation of water on the leaf surface and facilitate survival.

(5) after planting, cover the ground surface with grass between rows and near tea seedlings, and water regularly early in the morning to keep the soil moist.

3. False planting

In the case of dry and early climate, tea seedlings can be planted under the condition that the water supply can not be satisfied when planting.

The main results are as follows: (1) the yellow soil plot with cooler and better site conditions near water source is selected as pseudo-planting land.

(2) Open the shallow ditch according to the line spacing of 15 cm, arrange the tea seedlings according to the 3 cm plant spacing in the ditch, straighten the root system, cover the soil firmly, pour enough fixed root water, and then cover the soil to 5 cm beyond the mud door.

(3) cover the soil with grass between the rows, and cover the tea seedlings with a small amount of thatch or straw.

(4) after pseudo-planting, the soil should be watered frequently to keep the soil moist, and then transplant according to the technical requirements after the rain has penetrated.
