Mimosa, also known as Mimosa, is a perennial herb in Leguminosae. Plant height is 20 ~ 60 cm; 2 pinnate compound leaves, total petiole 3 ~ 4 cm long, lobules oblong. The flower head is axillary, the flower is small, the corolla is 4-lobed and reddish, the flowering period is from July to 10, and the seeds are wide and ovoid. Originated in tropical South America, it is now widely distributed in various tropical regions, especially in southern China. Sow and breed.

It can also predict earthquakes. Flower language: shy.

growing environment

Mimosa is native to tropical South America. It has strong adaptability, likes warm and humid, grows well in moist and fertile soil, is not cold-resistant, is lax in soil requirements, likes light, but can tolerate semi-shade, so it can be used as an indoor potted flower for viewing.

morphological character

Load mimosa

Perennial herb (annual after cultivated in southern China) Leguminosae, about 20 ~ 60 cm high, with many branches, scattered barbed hairs and sharp thorns. The leaves of mimosa have quite long petioles, and the front end of the petiole is divided into four feather shafts, each of which has two rows of oval small feathers. The total stalk is very long, and the base expands into a leaf pillow, that is, there is a hypertrophy part at the base of the small feather, feather axis and petiole of mimosa, which is called a leaf pillow. The leaves are bipinnately compound, with 2-4 pinnates, palmately arranged, lobules 14-48, oblong, 0.6- 1. 1 cm in length and 0 1.5-2 mm in width, with bristles on the edges and veins. Flowering after midsummer, the head is oblong, and 2 ~ 3 flowers are born in the axils of leaves. The flowers are reddish, the calyx is bell-shaped, there are 8 tiny calyx teeth, the petals are free, the stamens are 4, and the ovary is hairless. The pod is flat, with a length of 1.2 ~ 2 cm and a width of about 0.4 cm. It has 3 ~ 4 pods, each pod has 1 seed, and falls off at maturity. Flowers bloom in September.

Propagation and cultivation

Load mimosa

Mimosa is a straight-rooted plant with few fibrous roots, which is suitable for sowing and breeding. It is best to use direct seeding to avoid root injury after transplanting. If it must be transplanted, it should be transplanted at the seedling stage, otherwise it will not be easy to survive. As an annual cultivated mimosa, it is usually sown indoors in early spring.

type

Seeds can be sown in spring and autumn. Before sowing, the seeds can be soaked in warm water at 35℃ for 24 hours, and then planted in a shallow basin, covered with soil 1 ~ 2 cm. Soak water in a pot, keep it moist, and sprout at 15 ~ 20℃ for 7 ~ 10 days, when the seedling height is 5 cm. When picking seeds, choose strong mother plants, strengthen management, pick with maturity in the fruiting period, and the pods will automatically crack when mature.

cultivate

There are no special requirements for maintenance and management. Generally, the soil can be cultivated, and there is not much fertilizer in the growing period. Thin liquid fertilizer can be applied for 2 ~ 3 times, and it is not advisable to use too much fertilizer.

Green leaves can grow strong, but don't be an apostle, because mimosa is mainly an interesting foliage flower, preferably small.

The planting technology of mimosa is simple and the management is extensive. The requirements for climate, sunshine and soil are not strict, but the fertile and loose sandy loam is better, and the warm and humid environment is better.

1, planting method. Generally sow and propagate, and sow from late March to early April. Spread the seeds evenly on the fine soil, covering about 65,438+0.5 cm. When the temperature is about 65,438+08℃, the seedlings can emerge in about 65,438+00 days (usually they will grow after being buried without special management). Seedling growth is slow, and it can be planted when it is 7 ~ 8 cm.

2. On-site management. The plant spacing in the field is 25 ~ 30cm, and the soil should be loosened, weeded and watered in time. Potted indoors, watered every day in summer 1 time. Fertilize every month 1 time. If you don't want the plant shape to be too big, you should reduce the amount of fertilization or even don't need fertilization.

3, pest control: basically no pests and diseases. If there are slugs, they can be controlled with fresh lime powder in the morning.
