Introduction to Clitoria ternatea and its planting method


Butterfly bean (scientific name: Clitoria ternatea Linn.) It is a plant of the genus Butterfly. They were climbing grass vines. Stems and branches are weak and flowing puberty.


Leaf length 2.5–5 cm; Short, linear, 2–5 mm long; Leaf 1.5–3 cm long; Flowers large, single axillary; bracts 2, lanceolate.


The pods are 5–11 cm long and about 1 cm wide; The seeds are thick, about 6 mm long, about 4 mm wide, with dark, bright moons—a period of flowers and fruits from July to November.


It is native to India and is cultivated in tropical regions of the world.


The entire plant can be used as green manure. Root and seed are poisonous. The flowers are large and blue, resemble butterflies, and can be used as ornamental plants.


Indian name - Aparajita


scientific name

Another name


Blue Butterfly, Blue Bean, Butterfly Bean


Leaf length 2.5–5 cm; Short, linear, 2–5 mm long; Leaflets 1.5–3 cm long; Masks grooved on the total axis of the leaf, leaves 5–7, but usually 5, thin paper or near membranous, broadly elliptical or sometimes nearly oval, 2.5–5 cm long.


1.5–3.5 cm wide, blunt apex, slightly concave, often with short, small convex tips, direct base, pubescent or sometimes glabrous on both sides, green or greenish-brown after drying; Small low; Like setos; Petiole petiole 1–2 mm long, and leaf axis pubescent.


Clitoria Turnatea.


Flowers broad, single ax; bracts 2, lanceolate; bracteoles large, membranous, subcellular, green, 5–8 mm in diameter, with a clear lattice; calyx membranous, 1.5–2 cm long; Longitudinal veins, 5-lobed, lobes lanceolate, less than 1/2 of the calyx tube; Top protruding; Corolla blue, pink or white, up to 5.5 cm long, flag petals wide obovate, about three diams.


Centimeters with a white or orange-yellow halo in the center, the taping base, small stall, wing valves, and wedge valves are much lower than those of the flag valves, with both stalks, wing valves oblate oblong, wedge valves oval; Stamens disordered, ovary pubic.


The pods are 5–11 cm long and about 1 cm wide, flat, with a long beak, and have 6–10 seeds, the seeds are diagonally, about 6 mm long, about 4 mm wide, black, with bright moons. With a Period of flowers and fruits from July to November.


It is native to India and is cultivated in tropical regions of the world. It grows well in well-drained, loose, and fertile soil.


Breeding method


Soaking seeds


Fresh butterfly bean seeds do not germinate due to hard seed coat or slow water absorption, the germination rate is meager, and emergence is difficult, especially as dry seeds have a longer germination time. Therefore they should germinate before sowing to promote early development.


Germination usually adopts methods such as mechanical scratching of the seed coat, hot water, sulfuric acid, and potassium hydroxide treatment. The typical way is to choose seeds that are ripe, complete and disease-free, and soak them in hot soup at 40–80 ℃ for 15 minutes, but temperatures in the range 40–60 ℃ are favorable for seedling growth.


Then remove the seeds and drain the water, wrap them in a wet towel and germinate at 20–30 ° C. 20–30 ° C is the appropriate temperature for germination of butterfly bean seeds, of which 30 ° C is the optimal temperature; The grain will be after 2-3 days; Germination began, but germination rates were low, and emergence was not regular, so the actual amount of seed used to germinate is usually four times the expected seed amount.


Although the emergence of butterfly bean sprouts is fast, development is not ideal, but growth is robust.


Method of sowing


The sowing period should be determined according to the time of planting, usually 30 days before the planting period. Butterfly beans are generally sown and raised in the spring from February to March.


The specific method is to plug the bud tray into the seed tray, facing the root system, covering the soil with a thickness of about 1 cm, and pouring water.


The temperature in the spring is low, and the temperature should be above 20 ℃. The water follows the principle of watching it dry and wet, that is, the topsoil is dried, and then water is poured, neither dry nor watered.
