Is the red back cinnamon poisonous?

There is no poison, but it is a carcinogenic plant, so it is best not to keep it indoors for a long time. Experiments have shown that the "Epsteln-Barr virus early antigen inducer" contained in these carcinogenic plants can induce EB virus to transform into lymphocytes and promote tumor growth caused by tumor viruses or chemical carcinogens.

At present, experiments on nasopharyngeal carcinoma and esophageal cancer induced by carcinogenic plants have been confirmed that they are not only "poisonous" all over the body, but also activated substances containing carcinogenic viruses and chemical carcinogens have been detected in the soil where such plants have been planted.

If there are such plants in the house, people may cause cancer due to long-term inhalation of pollen, dust particles and other reasons.

II. Breeding methods and matters needing attention

Temperature

Red back cassia is a subtropical plant, which is not cold-tolerant. The suitable temperature for growth is between 15-25 ℃, and the overwintering temperature should be not less than 5 ℃.

Light

Resistant to semi-shade, like scattered light, avoid strong light exposure, summer needs to be placed in a shaded and ventilated place, which is conducive to keeping the red back cinnamon leaf color dark green.

Watering

Control watering in winter, generally watering every 7-10 days, basin soil is slightly wet and dry.

Fertilizer application

When planting or turning the basin and changing the soil, some compound fertilizer can be applied as the base fertilizer, the compound fertilizer containing nitrogen, phosphorus and potassium can be applied once in the growing period, and 0.2% potassium dihydrogen phosphate solution can be sprayed twice during flowering. Fertilizers are not needed in midsummer and winter.

Soil

Like fertile, loose, well-drained sandy loam.

Reproduction method

Two propagation methods of root division and cuttage can be adopted. The root splitting method is generally carried out in March or April of each year, and 2-3-year-old seedlings are selected for planting. The most common is cuttage propagation, select annual strong branches as cuttings, cut into every three segments into plain soil, about 23 cm deep, shade and moisturizing about two months can take root.

Matters needing attention

Anthracnose, leaf blight and root-knot nematode disease are common in pest control. The first two diseases can be treated by spraying 65% zinc wettable powder 500 times, and 3% carbofuran granules can be applied to the prevention and control of diseases. Red-backed cassia is easy to be harmed by scale insects, so pay attention to prevention and control.

The cultivation soil must be mixed with acid soil, and the basin should be changed every two years according to the growth situation. It is appropriate to keep it under the shade in the hot season, and applying acid liquid fertilizer every 2-3 weeks can make the branches and leaves luxuriant and keep the leaves bright.

The room temperature in winter should not be lower than 12 ℃, otherwise a large number of leaves will fall and the plants will go into dormancy, and the twigs will wither at the same time. If this happens, re-pruning should be carried out immediately to promote new shoots. Pay attention to the wind when moving out in spring, otherwise it is easy to cause the leaf to curl or even the leaf edge to dry up.
