Planting techniques of tea seedlings

Tea is one of people's favorite drinks, in China, the planting area of tea is very large, how to grow good tea, which requires certain technology, today we will learn about the planting technology of tea seedlings.

Planting techniques of tea seedlings

The main results are as follows: 1. The selected tea garden requires sufficient water source and convenient irrigation; the slope is less than 30 °; the soil layer is deep (more than 1 meter) and the groundwater level is low (less than 1 meter); the sandy loam with loose soil quality, good aeration, water permeability and water storage performance needs to be improved.

2. The best time to grow tea should be in the autumn and winter where the temperature is high and the aboveground parts of the tea plant stop growing, and the root system is more active in autumn and winter (mid-October, late October-early November) or early spring of the following year (mid-February-early March). Choose cloudy days or rainy days when the soil is moist and the air is moist.

3. Tea seedlings are planted immediately. Tea seedlings transported from other places are unloaded and the roots are lowered to a cool place to avoid direct sunlight, do not pile up, and cover with wet straw to preserve moisture. The roots of tea seedlings will inevitably be damaged when they are unearthed and transported. Therefore, the roots should be cut off before planting.

4. it can be planted in single row or double row, and large and small seedlings can be planted separately. The roots of tea seedlings should be stained with mud before planting. Mud concentration to the root of the tea seedlings stained with mud, but also can make the lateral roots stretch as the standard. Soaking can ensure that the survival of tea seedlings can reach more than 95%.

5. Planting tea seedlings by ditch planting method to create a good soil environment which is beneficial to the root system extending in depth. Therefore, when planting, first dig a planting ditch 10 cm deep on a good ridge or in a good shallow ditch, and then put the tea seedlings into the ditch, you should maintain the original posture of the root system, make the root system stretch, cover the soil while stepping on it, and then set the root water by topping.

6. The exposed area of the new seedling garden is large, which can cover plastic film or spread grass between rows or plant green manure, so as to reduce inter-row weeds and soil water evaporation, so as to improve the survival rate of tea seedlings.

7. Cut off more than 15 cm above the ground to reduce the evaporation of upper moisture, which is beneficial to root growth and sprouting lateral branches, and improve the survival rate.

8. Timely watering is needed during drought, especially in case of high temperature and drought within two months after planting and in summer days. It should be drained in time in case of overcast and rainy days, and tea trees are most afraid of waterlogging.

9. Styling and pruning is beneficial to thickening new branches and promoting the expansion of crown diameter as soon as possible. The first stereotyped pruning was carried out after the cuttings were transplanted. In the first set pruning, the main branches were cut off at 15 cm above the ground to retain the lateral branches; the second set pruning increased the main branches by 15 cm on the cut of the first fixed pruning, cutting off the main branches to retain the lateral branches; and the third styling pruning increased by 15 cm on the basis of the second stereotyped pruning, cutting off the main branches and retaining the lateral branches.

10. when the tea seedlings survived and the tender new roots grew out of 3-5 cm, suitable foliar fertilizer was selected for foliar spraying to promote the growth of tea seedlings and roots and improve the survival rate. In the second year after transplanting, topdressing 2-3 times, the first time in mid-late April, 20-25 kg compound fertilizer, the second in mid-July, 15 kg urea, and the third in mid-October, 40 kg compound fertilizer and 10 kg urea.

The cultivation of tea seedlings requires careful care, timely prevention and control of diseases and insect pests, and a good supply of water and fertilizer at each growth stage, so that good quality tea can be grown.
