According to the law of growth and development of tea trees, the upper part of the tea tree will gradually stop growing and enter the dormancy period. At this time, strengthening the management of winter tea gardens is the key to obtaining the increase of production and income of spring tea. To do this, we must make good "four passes":
Pruning off: The best period for light tea tree trimming in winter is when the autumn tea is harvested. When pruning, attention should be paid to the depth and location. To retain the red stem, cut the green stem as a degree, cut about 3 to 4 centimeters, and keep a little part of spring and summer, and cut the small green piles and leaves after the autumn harvest.
Clear Garden Pass: It can be started at the end of pruning work, mainly for pests and diseases. The specific measures are: the roots of tea trees, sheath blight and tea cake disease are removed and burned in a timely manner; the old leaves and branches of tea trees are scrutinized once and found, and eggs, worms and insects are found. The branches and branches of the clams are removed in time and the burns are concentrated. After the clear garden spray lime sulfur agent.
Spade shovel management: The weeds and tea trees are pruned under deep plowing, and the depth of cultivation is 10-15 cm. Shallow ploughing is performed inside the canopy, deep plowing outside the canopy, and sludging of the soil blocks.
Shi Fei Guan Fei Guan: Mainly to increase the manure, soil fertilizer, compost and other organic fertilizers. Fertilization must be carried out in time after weeding and weeding. Apply 200 kg of livestock and poultry excrement per acre, add 50 kg of dried oil, and mix 50 kg of calcium-US phosphate fertilizer for fermentation. During the fertilization, the drip line along the edge of the tea awning was deep-grooveed, and then the soil was covered.
