Matters needing attention in breeding Caragana

When fertilizing Caragana, we must pay attention to controlling the concentration of fertilizer, and we should not apply too much fertilizer at will just because we expect it to grow rapidly, which will cause damage to the roots of Caragana. In addition to not watering too much, we should also choose flowerpots with good drainage. In addition, the sandy soil with good drainage and fertile soil is the best choice.

Breeding methods and matters needing attention of Caragana

Culture methods of Caragana, temperature and light

Caragana likes light and cold, and likes a warm environment. Caragana can be placed in a place with plenty of sunshine and smooth air to maintain and give enough sunshine. But the summer is hot and hot, and the sun is strong, so it is necessary to shade Caragana and keep it in a semi-shady place. In winter, you can put Caragana in a higher temperature indoor maintenance, try to put in a place with bright light. In the area south of the Yellow River, you can also spend the winter outdoors, preferably buried in the soil with pots.

Water and fertilizer management

Caragana in daily maintenance, watering should follow the principle of "no dry, no watering, watering thoroughly" principle, keep the basin soil moist, can prolong the flowering period. It is better to apply fertilizer with thin fertilizer, but we should also make appropriate changes according to the growth status of Caragana. For example, fertilizer can be applied during the winter dormancy period, liquid fertilizer can also be applied to blossom in spring, and topdressing can be applied after flowering.

Soil and basin change

Caragana usually changes the basin every 2-3 years, and the time to change the basin is in spring. When changing the basin, you can remove the old soil and trim the roots, and replant it. After that, Caragana was placed in the semi-shade to slow the root, and the normal management was restored after rejuvenation.

The best soil for Caragana is deep, fertile and moist sandy loam.

Matters needing attention in Caragana Culture breeding methods

Caragana can be propagated by sowing propagation, cutting propagation, split propagation and striping and other methods.

Pruning

Caragana should be pruned frequently in the process of growing. After falling leaves in winter, all kinds of diseased branches, dead branches and rotten branches can be cut off. When the plant grows again in spring, the branches can be more branched by pruning. When Caragana is growing vigorously, cut off the overgrown branches to keep the plant shape beautiful.

Shrubs, sometimes treelike, 1-4 m tall; old branches golden, glossy; twigs white pilose. Pinnately compound leaves have 6-8 pairs of leaflets; stipules hardened into needles on long branches, 3-7 mm long, persistent; leaf rachis 3-5 cm long, deciduous; leaflets lanceolate or narrowly oblong, 7-8 mm long, 2-7 mm wide, apex acute or slightly obtuse, prickly, base broadly cuneate, grayish green, both surfaces densely white appressed pilose. Pedicel 6-15 mm long, densely pilose, articulated in middle and upper part; Calyx tubular-campanulate, 8-9 mm long and 4-6 mm wide, densely appressed pubescent, calyx teeth triangular or lanceolate-triangular Corolla 20-23 mm long, upper petal broadly ovate or suborbicular, apex truncated and slightly concave, ca. 16 mm wide, with short petiole, winged stalk slender, slightly shorter than limb, ear short, toothed, keel with long handle, ear very short; ovary lanceolate, glabrous. Pods flat, lanceolate, 2-2.5 cm long, 6-7 mm wide, sometimes sparsely pilose. Flowering in May and fruiting in June.

Produced in Inner Mongolia (northwest of Yikezhao League, Bayannur League, Alashan League), Ningxia, Gansu (Hexi Corridor). Born in semi-fixed and fixed sand. It is often the dominant species. The type specimens were collected from Ordos, Inner Mongolia.

Excellent sand fixation plants and soil and water conservation plants.

According to the specimen description of northwestern Ordos, Kubuqi Desert and Helan Mountain in Inner Mongolia, the ovary of V. L. Komarov is densely pubescent. This feature was identified in the key to C. microphylla Lam. The main difference. However, in the quoted specimen No. 5, the collector G. N. Potanin recorded that the young fruit was glabrous. In the picture of V. L. Komarov t. 16. F. B, the young fruits of the newly withered flowers are not hairy. We observed a large number of specimens from the producing area, and the ovary was completely glabrous. Therefore, we suspect that the original description is incorrect and we are waiting for the type specimen to be examined.
