Detailed Explanation of Key Technical Points for Tea Seedling Cultivation and Planting
SummaryLand preparation and trenching: For tea seedling cultivation, a plot with a soil pH of 5.5-6.5 should be selected. After land preparation and trenching, apply sufficient base fertilizer, then after covering with soil, apply the second layer of base fertilizer, backfill with pure soil, and plant after the loose soil has settled. Planting tea seedlings: Plant according to the size of the tea seedlings separately, with 2 tea seedlings per clump. After planting, water the soil thoroughly, and apply compound fertilizer 5cm away from the root collar of the tea seedlings. Heeling-in: If drought weather occurs, heeling-in can be carried out.
I. Tea Seedling Cultivation and Planting Techniques
1. Land preparation and trenching
(1) Digging planting trenches: Select suitable soil with a pH of 5.5-6.5. After plowing the garden plot, according to the double-row strip planting specifications, the large row spacing is 120cm, the small row spacing is 33cm, the clump spacing is 30cm, the planting trench width is 50cm, the depth is 50cm, and the bottom layer is loosened to 10cm.
(2) When digging trenches, the subsoil and topsoil need to be piled separately. When backfilling, bury the topsoil in the bottom layer, and place the subsoil on the surface. For single-row strip planting, the row spacing is 110cm, the clump spacing is 33cm, the planting trench width is 30cm, the depth is 50cm, and the bottom layer is loosened 10cm.
(3) After the planting trenches are dug, apply base fertilizer in the trenches, applying 2000-3000 jin of weeds or barn manure per mu, then cover with 20cm of soil, stir evenly with the soil, and then cover with 10cm of soil.
(4) Then apply the second layer of base fertilizer, applying 200 jin of cake fertilizer per mu, as well as 200 jin of special fertilizer for tea plants, backfill with 20cm of pure soil, wait for a period of time until the loose soil settles, leaving a 15-20cm deep concave trench, and finally plant.
2. Planting tea seedlings
(1) Grade the tea seedlings by size, then plant them separately. In the previously made concave trench, first open two shallow planting trenches 10cm deep, then arrange the tea seedlings in a staggered “pin” shape in the planting trench, planting 2 per clump. The tea seedlings need to be held upright, and the root systems straightened.
(2) Then cover with soil up to the mud gate and press lightly and firmly. After watering the soil thoroughly, apply special fertilizer for tea plants, or compound fertilizer, 5cm away from the root collar of the tea seedlings, then cover with soil to more than 5cm above the mud gate. After planting the tea seedlings, carry out timely shaping pruning at 15cm above the ground, which helps reduce water evaporation from the leaf surface and improve the survival rate of tea seedlings. After planting, spread grass between the small rows and around the tea seedlings to cover the ground. In dry weather, water frequently to keep the soil moist.
3. Heeling-in
(1) If drought weather occurs and water cannot be supplied during planting, the tea seedlings can be heeled in. Choose a relatively shady yellow soil plot with good site conditions and near a water source for heeling-in, then open shallow trenches at a row spacing of 15cm, arrange the tea seedlings in the trenches at a plant spacing of 3cm, and straighten the root collars.
(2) Then cover with soil and press lightly and firmly, water the soil to moisten it, then cover with soil to more than 5cm above the mud gate, spread grass between the rows to cover the soil surface, and cover the tea seedlings with some thatch or rice straw. After heeling-in, water frequently to keep the planting soil moist. After it rains, transplant and establish them according to the technical requirements.
