Propagation methods of Metasequoia Metasequoia Metasequoia generally include sowing propagation and cutting propagation, which can be selected according to the actual situation. Cutting propagation of Metasequoia glyptostroboides is the fastest, while others are relatively slow. Hydroponic propagation of Metasequoia glyptostroboides is not recommended because the survival rate will be low. Can Metasequoia glyptostroboides seeds reproduce? Metasequoia glyptostroboides seeds can reproduce and germinate as long as there is no problem with the seeds.
Metasequoia glyptostroboides naturally reproduces its offspring by sowing, which is a kind of reproduction method for many plants to reproduce their offspring naturally.
When is the survival rate of Metasequoia glyptostroboides high? Different transplanting seasons have great influence on the survival rate of Metasequoia glyptostroboides. From the point of view of plant ecology, the best season for transplanting Metasequoia glyptostroboides in a large area is from the autumn of that year to the time before the new buds sprout and grow leaves in the next spring.
Common propagation methods of Metasequoia Metasequoia Metasequoia Cutting propagation Metasequoia Metasequoia can be propagated by cutting, either by hardwood cutting or by softwood cutting.
1, hardwood cutting
Selection of cutting mother tree: cut 1 year-old robust branches from 2-3-year-old mother trees as cuttings.
Cutting time: 65438+ 10 in June and 10 in March.
Specification and treatment of cuttings: the length of cuttings is 10- 15cm, and then 100 cuttings are bound with sand to soften, keep warm, moisturize and prevent freezing. Before cutting, soak 10 cuttings in rooting powder solution with the concentration of 100mg/LABT 1.
Post-harvest management and cutting method: cutting in field with 20,000-30,000 plants per mu. After cuttage, seedlings are raised in full light, watered, weeded and loosened in time.
Results: The branches soaked with ABT rooting powder took root 15-20 days in advance, with many thick roots, and the survival rate was over 90%, which was about 35% higher than that of other branches without ABT rooting powder.
2. Soft cuttings
It will be held from late May to early June. Select semi-lignified shoots as cuttings with the length of 14- 18cm, leave 4-5 pinnate leaves at the top and upper part, insert them into the soil for 4-6cm, and insert 70,000-80,000 plants per mu. Shade after insertion and spray 3-5 times a day. The sunshade can be removed after the end of September. Nursery is often kept moist and ventilated, which can promote cuttings to take root as soon as possible. Pay attention to the prevention and control of damping-off and stem rot at seedling stage.
Seeds of Metasequoia glyptostroboides were collected after sowing and propagation, exposed to sunlight, screened, dried and stored. Spring is sown in March. The sowing amount per mu is 0.75- 1.5kg, and it is suitable to drill (row spacing is 20-25cm) or broadcast. After sowing, the grass should not be too thick, and the soil should always be moist.
Precautions for Metasequoia glyptostroboides reproduction 1. The newly planted Metasequoia bonsai has no new roots, the original roots are injured, they can't absorb water, and the branches are easy to dry up.
2. Spray it with a watering can in the morning and evening, and wet the branches to wet the bark.
3. The newly planted bonsai of Metasequoia glyptostroboides should not be watered more, otherwise the stump will germinate too much and the root system will grow slowly, which will not meet the evaporation needs of buds and cause the stump to wither.
4. So try to control the amount of water. After the new roots and buds appear, just pour a proper amount of water according to the number of new buds.
