The difference between Chunlan and Chunjian

Spring orchid, also known as grass orchid, is one of the orchids. Morphological features: pseudobulb is slightly globose, leaves 4-6 aggregate, narrow band, 20-60cm long, a few up to 100cm, 0.6-1.1cm wide, margin serrulate, flowers solitary, a few 2, scape erect, sheath 4-5, flower diameter 4-5cm light yellowish green, green-white, yellow-white, fragrant, sepals 3-4cm long, 0.6-0.9cm wide, narrow moment round, tip acute or obtuse, tight edge There are purplish brown stripes at the base of the midrib, petals ovate-lanceolate, slightly curved, slightly wider and shorter than sepals, reddish brown stripes in the middle of the base, labellum 3-lobed inconspicuously, shorter than petals, apex reversing or short and hanging down, light yellow in color, with or without purplish red spots, labellum has two folds in florescence from February to March. Spring Jian is a variety of Chunlan. Spring Jian is often called authentic Sichuan orchid. Although there are famous products in Yunnan, Guizhou and Sichuan, Sichuan orchid is the most expensive. Morphological features: leaves erect, flower stems erect, 20 to 30 cm high, 2 to 5 flowers, sometimes 7 flowers, flower bracts longer than ovary peduncles; flowers 5 to 6 cm in diameter, light yellowish green, often translucent and fragrant. The sepals are oblong-lanceolate, the middle sepals are erect and slightly tilted forward, the lateral sepals are oblique to the left and right, the petals are shorter than the sepals, there are three purplish red stripes at the base, and the lips are obtuse and anti-curled. Spring sword leaf posture tall and straight Cangjian, exquisite, quite elegant. There are red, yellow, white, green, purple, black and complex colors, gorgeous and dazzling, slim appearance, elegant charm, pure fragrance, often the first choice for orchid people. Spring Jian was first regarded as a variety of Cymbidium, and later it was designated as an independent species. Growth habits: the suitable temperature for growth of Chunjian is 18-28 ℃, no more than 35 ℃ in summer, no less than 2 ℃ below zero in winter, and the temperature of reproductive growth is 8 ℃. Spring sword's requirement for air humidity is 55%, 70%, not less than 50% during winter dormancy (the driest air exercise), and the best air humidity during the growing period should be kept at about 70%. Spring sword for water requirements: spring sword like cool, pot soil should not be too wet, flowering time and growth period appropriate more watering, dormant period should be less watering. Spring sword should be cultivated in deep tube plain burnt tile pot. Its pseudo-bulb sets form clusters, which are elliptical and spherical, and its roots are stout. Both pseudo-bulbs and thick roots have certain water retention and can cope with drought for about 6 days in a short period of time. Spring sword requirements for light: the light condition suitable for the growth of spring sword is semi-overcast, shading 65% and 75% in summer and autumn, and increasing light appropriately in winter and spring. Spring sword and spring orchid have similar habits, can be cold-resistant and can survive the winter smoothly at room temperature. In winter, it is also necessary to fully expose the sun to make the flower buds full and strong. Spring sword should be cultivated in spring, and replanting should be carried out after flowering. If it is raw grass, it can be planted before it blossoms in spring, and the flowers will be seen soon. The spring sword blossoms a little later. Spring sword is very weak in resistance to brown spot, which should be paid special attention in summer and autumn. 50% thiophanate methyl 800-fold solution or 50% carbendazim 800m 1000-fold solution can be used for control. The spot of the disease spreads from October to November, which can seriously make the whole plant die, and the leaf buds may be very weak in the coming year. Therefore, when diseased plants are first found, the diseased leaves should be cut off in time, and the diseased basin should be isolated.

How to distinguish between Chunlan and Chunjian? 1. Chunlan, commonly known as orchid, grass orchid, orchid, blossoming fragrance, is one of the most widely distributed orchids in China. Spring swords are mainly produced in the mountains of western Sichuan, as well as in Yunnan and Guizhou. Spring orchid and spring sword are both varieties that bloom in spring and have fragrance.

On the other hand, the color of spring sword is mainly light yellow-green, purple-red and complex color. two。 Spring sword leaf 4Mel 7, apex acuminate, leaf color dark green, slightly glossy, erect, sword-shaped, wider and longer than Chunlan leaf, leaf margin serrulate, coarser and sharper than Chunlan leaf tooth, leaf back with 3 veins, midvein prominent, cross section V-shaped. The leaf base has no ring (abscission). Spring orchid leaves 4-6, leaf posture mostly erect leaves, semi-drooping leaves, drooping leaves, yellow-green and green, green. The leaf base has a ring (abscission). 3. The orchid head (pseudobulb) of Chunlan is spherical, the root is fleshy, thin round and gray-white, while the root of Chunlan is not obvious, and the root is longer and stronger than that of Chunlan. 4.
