Cultivation techniques of tea seedlings

Soil preparation and ditching: the cultivation of tea seedlings should select the land with soil pH value of 5.5-6.5, apply sufficient base fertilizer after soil preparation, apply the second layer of base fertilizer after covering the soil, backfill the pure soil, and plant after the loose soil sinks. Planting tea seedlings: according to the size of tea seedlings, 2 tea seedlings can be planted in each clump. After planting, the soil should be watered thoroughly, and 5cm compound fertilizer should be applied to the roots and stems of tea seedlings. Artificial planting: if there is a dry climate, artificial planting can be carried out.

I. cultivation and planting techniques of tea seedlings

1. Land preparation and trenching

The main results are as follows: (1) the suitable pH value of soil is 5.5-6.5. after ploughing the garden, according to the specification of double-row strip planting, the large row spacing is 120cm, the small row spacing is 33cm, the cluster spacing is 30cm, the planting ditch width is 50cm, the depth is 50cm, and the bottom layer is dug to 10cm.

(2) the subsoil and topsoil should be stacked separately when opening the ditch, and the topsoil should be buried in the bottom layer when backfilling, and the subsoil should be placed on the surface layer. The row spacing of single row strip planting is 110cm, the cluster spacing is 33cm, the width of planting ditch is 30cm, the depth is 50cm, and the bottom layer is digging loose 10cm.

(3) after the planting ditch is opened, base fertilizer should be applied in the ditch, applying 2000-3000 jin of weeds or column manure per mu, then cover the soil 20cm, mix with the soil evenly, and then cover the soil 10cm.

(4) then apply the second layer of base fertilizer, 200kg cake fertilizer per mu, and 200jin special fertilizer for tea trees, backfill pure soil 20cm, after a period of time when the loose soil sinks, it will leave a deep groove of 15-20cm, and finally plant it.

2. Planting tea seedlings

The main results are as follows: (1) the tea seedlings are graded according to size, and then planted separately. In the previously made grooves, two shallow planting ditches with a depth of 10cm are opened, and then the tea seedlings are staggered and arranged in the planting ditch according to the shape of "product". There are 2 plants in each clump, so it is necessary to straighten the tea seedlings and straighten out the roots.

(2) then cover the soil to the mud door and gently soak the soil. After soaking through the soil, apply special tea tree fertilizer or compound fertilizer to the 5cm from the root and stem of the tea seedling, and then cover the soil above the mud door 5cm. After planting the tea seedling, the off-ground 15cm should be shaped and pruned in time, which is beneficial to reduce the water evaporation of the leaves and improve the survival rate of the tea seedling. After planting, grass should be covered on the ground between the rows and around the tea seedling Water the soil frequently when the weather is dry to keep the soil moist.

3. False planting

The main results are as follows: (1) if there is a dry and early climate and there is no water supply during planting, the tea seedlings can be pseudo-planted, and the pseudo-planting site should be selected in the yellow soil plot with relatively cool, good site conditions and close to the water source, and then the shallow ditch should be opened according to the specification of row spacing of 15cm, and the tea seedlings should be arranged according to the plant spacing of 3cm, and the roots should be straightened.

(2) then cover the soil gently and steadily, water the soil moist, cover the soil beyond the mud door 5cm, spread grass between rows to cover the surface of the soil layer, and then cover the tea seedlings with some thatch or straw, often water the planting soil after pseudo-planting, wait for rain, and then transplant according to the technical requirements.
