After the autumn tea picking is basically completed, how to timely make a good scientific management of the tea garden relates to the restoration and growth of the tea tree canopy, and also relates to the output and quality of the tea next year. Therefore, the following tasks must be done in time:
First, do a good job of improving the soil of tea gardens.
1, deep plowing and weeding. After the end of the autumn tea planted in the tea plantation, the entire garden should be deep-turned to a depth of 25 cm or more to loosen the soil, promote soil microbial activity, weather the subsoil, and increase the ability of the soil to absorb and absorb water. At the same time, weeds are pressed into the soil layer in and around the garden with deep turning, and weeds in the tea plantation ladder are cut off by hand or by a lawn mower and buried in the soil between the rows to make fertilizer.
2, combined with deep organic fertilizer. Deep plowing has good effects such as strong ripening soil, improved soil, thickening tillage layer, and reducing the occurrence of pests and diseases in the following year. After deep plowing, deep application of organic fertilizers, green manures, etc. as base fertilizers has two effects: First, it plays a major role in restoring tree vigor, preventing soil “aging†and impoverishment, and improving soil structure. The second is a decisive role in early spring and multiple high quality spring tea. The amount of basal fertilizer generally accounts for 30% of the annual fertilization amount. Young tea plantations use 1000-1500 kilograms of farmyard fertilizer per acre, or 50 kilograms of commodity organic fertilizer, plus 20 kilograms of phosphorus and potassium fertilizer; Adult tea plantations use 2000-2500 kilograms of farmyard fertilizer or 100 kilograms of commodity organic fertilizer per acre. Phosphorus and potassium fertilizer each 30 kilograms. When applying fertilization, the tree canopy should be placed between the rows of trees in the tea plantation at a distance of 20-30 cm and then covered with soil.
3, do a good job of soil culture garden. Tea plantation land refers to the cultivation of red soil, yellow loam soil, soil, and paddy field soil on the outside of clean soils such as tea gardens or other slopes to the tea gardens and to the base of the tea tree. The thickness is about 10 cm. It is generally required that the clay soils in the clay soil should enter the sandy red soil, the sandy soil tea gardens should enter the clay soil, and the low-yielding tea gardens and the aging tea gardens should enter the red and yellow soil areas. Land and soil can be used to thicken the tillage layer, increase soil vitality, prevent soil “ageingâ€, promote early spring tea germination, and improve the quality of fresh leaves.
Second, do a good job of tea tree pruning
For adult tea gardens, light pruning should be combined with clearing the feet, trimming the edges, trimming, etc. For young tea plants, cultivation should be the main method and the canopy should be cultivated; for the old tea tree, heavy pruning should be performed to restore the crown growth and increase yield. And quality.
1, light pruning: refers to the pruning of the tea plantation has been put into operation once a year, the purpose is to control the tree height and cultivate the crown picking surface. Generally cut 3-5 cm of the crown, so that the height of the tea tree is controlled at about 50 cm.
2, clear pockets: This pruning method can promote the ventilation of the lower part of the crown, reduce the occurrence of pests and diseases. Edge trimming is beneficial to the ventilation and light transmission in the tea garden and field work, and can promote the growth of tea plants and reduce the occurrence of pests and diseases.
3. Edge extension pruning: Edge extension pruning is the pruning of the tea gardens that have been closed to form rows of air passages, cutting off the cross branches, and maintaining a uniform ventilation path of 20-30 cm between the tea gardens.
4. Heavy pruning: refers to pruning of tea gardens with weak tree vigor, sparse sprouts, low yield, and poor quality. Generally, the height of the tree canopy should be trimmed to a third.
