How tea plantations are transformed
When the tea plantation production is difficult to improve, the quality of the medium-and-low-yield low-value, the decaying tea plantation, or the hand-picking tea plantation is changed to the tea plantation, the purpose of increasing the value-added and suitable production can be achieved through the transformation of the tree canopy. The reconstruction of the tea garden requires the combination of crown reconstruction and soil remediation, combined with machine repair and machine mining. There are three methods for crown reconstruction: deep pruning, heavy pruning, and table cutting. Deep pruning: Cut the 15-20 cm green leaf layer of the tree crown. It is suitable for tea gardens with good tree vigor and the formation of chicken claw branches. It is generally suitable for trimmer operation. Heavy pruning: pruning from the ground 30-40 cm, suitable for tea gardens with high tree or decline of tree vigor. When the branches are thicker than 1.2 cm, the upper part is cut off with a knife and the upper part is cut with a trimmer when the branches are less than 1.2 cm thick. Bench cut: pruning 10-20 cm away from the ground, suitable for aging tea gardens where tree vigor is severely degraded. It is generally cut with a hatchet and is ideally used with brush cutters. The appropriate time for the transformation of tea gardens is in late May, ie early after the end of spring tea. Crown transformation should be combined with soil improvement and fertility increase. Normally, 40-50 kg of urea or compound fertilizer or the corresponding fertility of farmyard manure trimmed branches can be used as a fertilizer directly in the tea line.
