Transplanting techniques of improved Tea Clone varieties

1. @ # @ 185mm

The transplanting of improved seedlings is generally located in terraced land, gentle slope land and flat early land, with deep soil layer, good structure, shelter from the wind and abundant water resources.

2. Land preparation

It will be completed 10-15 days ahead of schedule. Strip planting, border width 1 meter; require deep trench hanging trough, ditch depth 25 cm 30 cm, width 24 cm 30 cm, apply base fertilizer at the bottom of the ditch, base fertilizer mostly use rotten cake fertilizer and tea special fertilizer, 150 kg cake fertilizer and 50 kg special fertilizer per mu; after fertilization, the topsoil is backfilled into the ditch to keep the soil depth about 20 cm, so as to avoid direct contact with fertilizer and burn the roots of tea seedlings.

3. Transplanting period

The best time for transplanting tea seedlings is before tea bud germination in spring and after tea bud stops growing in autumn. Rain Water is less in this county after autumn, and the frost injury is serious in winter, so it is safer to transplant in early spring. The specific transplanting period is between stinging and vernal equinox, when the tea seedlings have not yet sprouted, the transplanting survival rate is high, and the recovery is fast.

4. Transplanting method

The height of transplanting tea seedlings is about 20 cm, the stem is about, the stem is strong, and the root system is well developed. when transplanting tea seedlings, there should be more soil and less root damage. When planting seedlings, the method of low planting in deep trench should be applied, with a distance of 27 cm to 35 cm in a single row, 2 plants in each hole, planting in the ditch, filling fine soil layer by layer, stretching the root system, trampling the soil, watering through the fixed root water, and keeping the tea seedling after planting. The mud door is about 10 cm below the ground surface, and the lower half of the tea seedling is thin in the ditch. After the tea seedling grows high, the ditch will be filled with weeding and fertilization. This method can keep heat and moisture and prevent wind, reduce drought and freezing injury, help tea seedlings to root deeply, increase rooting level and promote aboveground growth.

5. Post-transplanting management

Tea seedlings planted in spring must be cut 15cm and 20cm from the ground in order to keep the water loss of tea seedlings in sunny days affect the survival rate. In terms of management methods, it is divided into three seasons: first, to survive in spring, it is not suitable to hoe or fertilize as early as possible. generally, after the Beginning of Summer, the new root system of the underground part grows more than 2 cm 3 cm, and the new shoot of the aboveground part grows to 5 cm 10 cm. Fertilizer can be applied only when the new root system grows more than 2 cm and when the aboveground new shoot grows to 5 cm. Fertilization standard, adopt hole application, 10 kg of urea per mu or about 10 kg of 30% urea or foliar spray of 3% urea. If there are too many weeds, glyphosate or Nongda can be sprayed to inhibit; second, to promote growth in summer, it is necessary to turn off good water and fertilizer, timely watering in case of drought, and timely drainage in case of waterlogging. The amount of fertilizer application can be doubled, once every 20 to 30 days, and the second pruning can be carried out when the branches are more than 30 centimeters, and the height is 25 centimeters away from the first cut. In autumn, Rain Water is less, so we must strengthen drought prevention and increase the application of human feces and urine or rotten cake fertilizer and water as base fertilizer. The summer and autumn season is the peak period for the occurrence of diseases and insect pests. Once found, biological control should be carried out in time.
