Breeding points of Aristolochia mandshurica

Aristolochia mandshurica can be made into a potted plant and placed at home, which can not only be used for viewing, but also beautify the environment and purify the air. Aristolochia mandshurica is also cultivated in some mountain forest scenic spots, which can provide a large number of negative ions for the air. Artificial propagation of Aristolochia mandshurica can be done by means of ramet and sowing, generally mainly by ramet propagation.

Aristolochia mandshurica

Aristolochia mandshurica is commonly used for ramet propagation and can also be sown. When the seedling has more than 6 leaf clusters, it can be divided, which is often carried out in the dormant period after anthesis. Remove the clump from the flowerpot, remove the attached culture soil, break it with your hand, and plant it separately. After planting, the seedlings were placed in low light, and the seedlings could be cultivated normally when the growth was restored. For sowing, because the seed is small and the embryo is not fully developed, the aseptic embryo should be cultured in the test tube. After germination, the seedlings can be divided and transferred for three times. When the seedling is high 3cm, it can be removed from the test tube and cultivated in the flowerpot. It takes 5 years from sowing to flowering. It is often used for the breeding of new varieties or the mass propagation of seedlings.

Introduction and maintenance of Paphiopedilum (Slipper Orchid)

Paphiopedilum (slipper orchid)

Scientific name: Paphiopedilum

Families and genera: Orchidaceae, Paphiopedilum

Distribution: tropical and subtropical Asia. All belong to about 70 species.

Maintenance points: perennial evergreen herbs. Most of them are geophytes and a few are epiphytes. One of the most widely cultivated orchids in the world. Because of its peculiar shape, lip pocket shape and rich colors, it is deeply loved by people. Rotten leaf soil or peat soil is planted in small pots, and epiphytic species are planted with bark blocks. Fertilize every two weeks or so during the growing period, and always keep the basin soil moist and breathable. Like the semi-overcast and cool environment, about 50% shade in spring, summer and autumn; alpine species, it is appropriate to put in a cool and ventilated place at high temperature in summer. The overwintering temperature is 10: 15 ℃. The green species of leaves are more hardy.

Caiyun Paphiopedilum P.wardii

Hainan Dolan P.appletonianum

Aristolochia paniculata P.concolor

Hong Kong Paphiopedilum P.purpuratum

P.villosum of Aristolochia purpurea

Reproduction: ramet and aseptic sowing.

Light: need light, slightly resistant to overcast (semi-overcast).

Moisture: growing in moist soil.

Temperature: slightly cold-resistant, able to withstand-5: 0 ℃ low temperature.

Humidity: like to be moist, the relative humidity is higher than 60%, generally 70% to 90%.

Key points for the cultivation of Paphiopedilum (slipper Orchid) Aristolochia belongs to Magnolia, which has a strange flower shape, long flowering period and rich color. There are many people who like Aristolochia, but at present, the cultivation of Aristolochia is not common, mainly because many orchids do not master its habits, resulting in repeated setbacks in cultivation. According to the shape, Aristolochia can be divided into two categories: green leaf species and variegated leaf species. The green leaf species have all green leaves, large flowers and bright colors. They are native to cool alpine areas, but are not easy to be cultivated in flat land in Guangdong. On the other hand, the variegated leaf species prefer sunlight and temperature, and can blossom normally on the flat ground.

Place: it is best to be in an orchid shed with shading, and it is well ventilated, do not put it too close to the window wall, and do not hang and cultivate.

Planting: Paphiopedilum is a terrestrial orchid, its root is different from other orchids, it is a kind of hairy root, the plant material should be a mixture of organic matter, such as water moss, serpent sawdust, sawdust, peat soil and so on. Rubble and bricks are available for floor matting, with a quantity of about 1 pound 5. The overall requirements should be loose and good drainage.

Lighting: Aristolochia does not like strong light, similar to Phalaenopsis, shading 60% 70% in summer, 50% 60% in spring and autumn, and 40% 50% in winter.

Temperature: the suitable temperature for the growth of green leaf species and variegated leaf species is 12-25 ℃ and 15-25 ℃, respectively, but it can survive above 30 ℃, but the growth is almost stagnant. Do not let the temperature exceed 22 ℃ from March to June, otherwise it is not easy to blossom.

Moisture: Paphiopedilum does not like the high humidity of the air, but it likes to keep the plant in the basin slightly wet, but not too damp, so it is best to pour "a small amount" of water every day.

Fertilizer: Aristolochia mandshurica is very particular about fertilization. Aristolochia is very sensitive to salt and must not be applied more, so as to avoid salt damage. It is better to apply less in general. People in Taiwan have a good way to prevent salt accumulation, that is, 1-2 hours after watering, after the salt in the substrate can be precipitated, water again. About every 15 to 20 days to spray about 2000 times water-soluble available fertilizer, non-flowering plants with Huabao 2 N:P:K=20:20:20 or the compound fertilizer commonly used in the market at 15:15:15, near flowering plants to supplement phosphorus and potassium fertilizer to promote flowering.

Reproduction: family cultivation commonly used split method: when the root base of the adult plant grows out of the young plant and has more than three new roots, it can be cut and replanted. Aseptic sowing and tissue culture are commonly used in commercial production.
