Scientific breeding tiger thorn plum abandoned carcinogenic rumors

Tiger thorn plum is also known as iron begonia. When blooming, small flowers stand in clusters of tender green and slender loquat-like leaves, with a few red spots in the green cluster, which is very lovely. Chimonanthus przewalskii is tenacious in vitality, and leaves will fall when the temperature is below 5 ℃ in winter, but don't throw it away because it is dead. It is only dormant for a short time. When the temperature rises in spring, it will still sprout new leaves, keep the temperature above 15 ℃, and keep enough light. It will blossom continuously all the year round.

The tiger thorn plum likes the sunshine, during the flowering, the sunshine is sufficient, then the bract color is bright, the sunlight is insufficient, the flower color is dim. If your farmed tiger thorn plum only grows leaves but does not blossom, in addition to excessive nitrogen fertilizer, it is likely to be caused by a lack of light.

Chimonanthus przewalskii does not like concentrated fertilizer, so it is generally recommended to apply mature organic liquid fertilizer every 20 days in spring, such as diluted cake fertilizer and water, less nitrogen fertilizer and more phosphorus and potassium fertilizer during bud pregnancy to promote flower bud differentiation. If the 1RU 1000 potassium dihydrogen phosphate solution is sprayed every 15 days, the flowers can be colorful.

The flowering period of the tiger thorn plum is long, and most of the flowers bloom at the top of the new branch, so the flowering period should be pruned in time in order to bloom more. The overlong and irregular branches can be cut short after the first flowering period. generally, two new branches grow under the cut mouth of the branches, and when the new branches grow to 5-6 cm, they can blossom.

The leaves of Prunus mume are fleshy, the whole plant has sharp thorns, and the white milky juice contained in the stem is poisonous and can stick to the small flying insects attached to it, which is a manifestation of plant self-protection and irritates human skin and mucous membranes. Accidental ingestion will lead to nausea, diarrhea and other toxic symptoms. There are rumors on the Internet that tiger thorn plum causes cancer, so that many flower lovers who like to breed tiger thorn plum have to give up and throw it away. in fact, this kind of rumor has no scientific basis. Cancer is caused by the EB virus, some scientists have confirmed that the extract of the branches and leaves of Prunus przewalskii has the ability to induce the early antigen of EB virus, but the plant itself does not produce EB virus, promoting cancer is not equal to causing cancer, and these cancer-promoting substances can be seen everywhere in life, from rubber to spices, from essential oils to plants, contain this metabolite.

Therefore, in the process of cultivation, as long as you avoid contact with the secretions of the plant itself, wear gloves during pruning, wash your hands in time after pruning, place the plum on a balcony or high place that is out of reach of children, and strengthen ventilation and environmental hygiene, you can not only enjoy the beauty of the plum, but also largely avoid the injury caused by the plum.
