How to plant Tieguanyin tea tree seeds?
The method of soaking seeds to accelerate germination is as follows: first, soak tea seeds in warm water at 25-30℃ for 4-5 days (change the water twice a day to remove the tea seeds floating on the water surface and destroy them), and then spread them on an indoor high sand bed (sand laying thickness is 5-6 cm) with a thickness of 7- 10 cm, and cover them with a layer of fine sand of 5-6 cm. Keep the room temperature at about 25℃ and sprinkle water once a day. The air in the germination room should be properly circulated. When 50% of the tea seeds are exposed from the radicle, they can be planted.
The sowing method of tea seeds can be hole sowing and single seed drilling, with the row spacing of single seed drilling being 20 cm and the material spacing being 3-4 cm. The row spacing of hole sowing is 20cm, the hole spacing is 15cm, and 4-5 tea seeds are sown in each hole. Immediately after sowing, cover the soil with a thickness of 2-3 cm. Spring sowing should be covered with shallow soil.
Miao Di prepared Tieguanyin:
Miao Di should choose farmland or paddy fields with flat terrain, fertile soil, abundant water, easy irrigation and drainage, shelter from the wind and convenient transportation. Fields that grow tobacco, marijuana and vegetables cannot be Miao Di. The soil structure should be loose, water-retaining and water-permeable, thick and slightly acidic sandy soil or clay. After deep ploughing, soil breaking and harrowing, Miao Di will be made into a seedbed with a height of10 ~15cm and a width of1/kloc-0 ~/20cm. Depending on the terrain, the east-west direction is better. The spacing between seedbeds is 30 ~ 40 cm. There are 80 ~ 100 cm deep and 50 cm wide water storage pits at both ends of the temple bottom. Irrigation and drainage ditches are set around the bottom of the temple. The seedbed should be fully applied with base fertilizer, which should be evenly spread on the seedbed, fully mixed with soil and leveled, and then spread with screened red soil core soil as soil, generally 4 ~ 6 cm thick, one mu 15 ~ 20 cubic meters, and then leveled with wooden boards.
Yin Di grid setting of Tieguanyin Temple:
Piling shall be carried out at intervals of 1.54 ~ 1.6 m on both sides of Tieguanyin seedbed, and bamboo strips shall be tied to horizontal and vertical stakes as scaffolding, with a height of 30 ~ 50 cm. Shading objects can be adapted to local conditions, such as thatch, wheat straw, fir branches, sunshade nets and bamboo curtains. Tieguanyin seedbed is covered with long curtains, the length is 3.0 ~ 3. 1m, the ditch is covered with grass curtains, the length is 1 ~ 1.2m, and the width is 0.8m Short curtains are used around Miao Di. Mountain brush can be used as shade in autumn or winter. The branches and leaves of the mountain brush are 25 cm above the ground. At the same time of transplanting seedlings, 2 ~ 3 branches are bundled and inserted directly between rows every 2 ~ 3 rows. The density of sunshade should be uniform, and the shading rate should be 70% ~ 80% in summer and 50% ~ 60% in winter.
Tieguanyin earnestly:
Choosing Tieguanyin cuttings is the key to the survival of cuttings, and branches with yellow-green semi-lignified stems, thick leaves, full axillary buds and no pests and diseases should be selected. 7 ~ 15 days after fresh leaves are picked, cuttings should be cut, impurity tips should be removed, and cuttings should be shipped back in time. They should not be under pressure, exposed to the sun or blown by the wind to prevent heating and withering. They should be laid in a cool and dark place, watered with water, and then cut into cuttings. Cutting should have one leaf and one axillary bud, the short stem under the leaf should be 2 ~ 2.5 cm long, and the cutting mouth should be smooth. The upper cut is 3 ~ 4 mm away from the petiole and should be inserted with the shear. Cutting dates are February-March in spring, late April-late May in summer, August-September in autumn and1~1February in winter, which is more suitable for Tieguanyin tea area. Practice shows that the summer temperature is high, and the spring shoots can be cut in that year, which is the best cutting time for rooting and shooting bamboo shoots. Cutting method: fully spray the temperature on the seedbed, and when it is slightly dry and not sticky, cut according to the planned row spacing, with the row spacing of large-leaf seeds of 9 ~ 10 cm and the spacing between plants of about 3 cm; The row spacing of lobular seeds is 6 ~ 7 cm, and the plant spacing is about 1.5 ~ 3 cm. It is advisable that the leaf edge and the leaf tip do not overlap, and planting 1.5 ~ 0.2 million plants per mu. Direct insertion or insertion leaves are slightly inclined, and the leaves should be downwind. Petiole and bud should be exposed on the soil surface, and leaves should not be soil. After insertion, shade and spray water until the culture soil is soaked.
