Is the Calliandra haematocephala poisonous? Detailed explanation of propagation methods

Calliandra haematocephala is not suitable for indoor placement; it grows best and has the highest ornamental value in a place with sufficient light. Is Calliandra haematocephala poisonous? What are the propagation methods:

Is Calliandra haematocephala poisonous:

Calliandra haematocephala is non-toxic, so everyone need not worry too much.

It is a deciduous shrub or small tree of the genus Calliandra in the Fabaceae family, fond of growing in warm and humid tropical climates, and is often cultivated as an ornamental flower with very high ornamental value.

What are the propagation methods of Calliandra haematocephala:

1. Seed propagation

The flowering period of Calliandra haematocephala is in August and September each summer, and the best seed collection period is in October. Select plump, intact, healthy seeds and store them in a dry, ventilated environment. Wait until the following spring to sow.

Before sowing, the seeds need to be soaked in clean water at a temperature of 60 degrees, changing the water once a day for three consecutive days, then removed. Keep them moist for germination. Sow the seeds in moist soil, and they will sprout in about one week.

2. Cutting propagation

In the cultivation of Calliandra haematocephala, cutting propagation is generally chosen; in spring, cut healthy branches about 20 cm long, remove dead leaves, and insert them into a moist sandy soil substrate. It is best to keep the temperature between 15——30°, and simply pay attention to shading and moisture retention.

Calliandra haematocephala must also be protected from pest troubles.

4. Family and genus introduction

The largest family of the Asteridae subclass of Magnoliopsida. It has a consistent floret structure. Florets tubular and radially symmetrical, or ligulate and bilaterally symmetrical, or corolla tubular with corolla lobes bilabiate. Many florets are densely arranged, covered externally by involucral bracts to form a consistent capitulum. A total of 13 tribes, over 1300 genera, nearly 220,000 species, distributed globally except Antarctica. China has about 220 genera and nearly 3000 species, distributed throughout the country, among which 15 genera are endemic to China, including Heterosperma, Diplazoptilon, Taihangia, Penicillium, Diplophyllum, Xanthopappus, Dolomiaea, Bolocephalus, Cavea, Pertya, Myripnois, Sinacalia, Sinosenecio, Formania, and Jurinea. The tribe Vernonieae is concentrated in northern and central South America, with greater development in Africa. The tribe Eupatorieae is concentrated in Central America. The tribe Astereae is globally distributed. The tribe Anthemideae is mainly a group of the Eastern Hemisphere, with very few species in North America. The tribe Inuleae is mainly distributed in Africa and Oceania. The tribe Cichorieae is mainly distributed in Europe, with great genus and species diversity also in North America. Among the 13 tribes of Asteraceae, the tribe Heliantheae is the largest, with 221 genera, mainly distributed in South America and North America; the smallest tribe is Tageteae, with only 11 genera, mainly distributed in South America; both tribes are entirely introduced and cultivated or naturalized in China.

2. Propagation methods:Use seed propagation, divided into autumn sowing and spring sowing. Autumn sowing is from after seed harvest until the ground freezes in early November; autumn-sown seeds begin to germinate in early April of the second year, and full seedlings emerge from late April to early May. Spring sowing is carried out from March to early April, with seedlings emerging from late April to early May. Spring-sown seeds must undergo low-temperature treatment to allow the embryo to develop and mature; if the seeds are sown dry, they will not emerge that year. Sowing methods are divided into drilling and broadcasting. Seed treatment: from late October to early November, mix the seeds evenly with moist sand at 1:3, then store in a pit; dig a soil pit 45 cm deep and 30 cm long and wide on a sunny slope, place a small amount of branches at the bottom of the pit, spread a layer of leaves on top, put the seeds in, then cover with 10 cm of soil; during sand storage of the seeds, pay attention to preventing rodent damage. Around Qingming of the following year, when most of the seeds have sprouted, sow again. Drilling: open shallow furrows 3 cm deep at a row spacing of 15-20 cm, sow the seeds evenly, cover with 3 cm of soil after sowing, and press down after sowing. The amount used per hectare is 22.5-30 kg. Broadcasting: spread the seeds evenly on the bed surface, cover with 2-3 cm of soil, after sowing make the seeds contact the soil, and press lightly. The sowing amount per hectare is 30 kg. After treatment, spring-sown seeds, with sufficient temperature and humidity, begin to emerge in about 10 days.

3. Field management
(1) Cultivation and weeding: carry out loosening of soil and weeding in time to prevent weeds from overwhelming the seedlings.

(2) Replanting and thinning: check and replant seedlings in time during the seedling stage; if too dense, thin appropriately; when gaps are found, replant in time on rainy days or in the evening, and water and preserve soil moisture after replanting. When the seedlings are 10 cm tall, thin to a final spacing of 15 cm * 10 cm.

(3) Topdressing: after final thinning, apply 150 kg of urea per hectare; after flowering, apply 225 kg of superphosphate per hectare; apply on rainy days or water after application.
(4) Drainage and irrigation: Arnebia is most afraid of waterlogging; pay attention to drainage during the rainy season to avoid root rot. If drought is severe, water appropriately.
4. Pest and disease control
(1) Root rot: occurs in high temperature or rainy seasons. Roots rot, and aboveground stems and leaves wither.
Control methods:
① Drain promptly after rain.
② Remove diseased plants and burn them, and disinfect the diseased holes with lime powder.
③ Irrigate the diseased holes with 1% ferrous sulfate for disinfection.
(2) Leaf spot: harms leaves, forming irregular lesions on the leaves.
Control methods:
① Pull out diseased plants promptly.
② Control with 1:1:100 Bordeaux mixture.
(3) The pests of Syneilesis aconitifolia include white grubs, mole crickets, cutworms, and weevils, which can be captured manually or poisoned with bait.
