Cultivation methods and matters needing attention for purple root orchid
Purple root orchid is popular for its elegant purple roots and gorgeous flowers, but many flower friends often encounter problems such as poor growth and difficulty in flowering during the maintenance process. As a perennial bulbous plant in the Amaryllidae family, its unique growth habits require scientific management methods to show its best ornamental value. This paper will systematically analyze the key points of full-cycle maintenance of purple root orchid. Growth environment regulation temperature and light management of purple root orchid 18-25℃ is the ideal growth temperature of purple root orchid, and the temperature difference between day and night should be controlled between 5-8℃. In winter, it is necessary to maintain a low temperature of 10-12 ° C to promote dormancy, and in summer, sunshade measures should be taken when it exceeds 30 ° C. Full sunshine can be accepted in spring and autumn. In summer, it is recommended to use 50%-60% sunshade net to ensure light scattering for 4-6 hours a day. The moisture control technique adopts the watering principle of "see dry, see wet", and the moisture content of the substrate is maintained between 40% and 60%. It is recommended to mix red pottery pots with a matrix formula of perlite + leaf soil (1:3) to ensure drainage. During the high temperature period in summer, spraying can be carried out in the morning and evening to increase humidity, but water in the leaf center needs to be avoided. Nutritional supply plan for purple root orchid cultivation methods and matters needing attention
It is recommended to use bone meal + decomposed sheep dung (1:2 mixture) for base fertilizer, adding 15g per liter of soil. Phosphorus and potassium liquid fertilizer (N-P-K=5-10-10) is added twice a month during the growth period, and the concentration is controlled at 0.1%-0.15%. Supplement slow-release fertilizer in time after flowering to promote bulbous rejuvenation. Breeding and daily management The key points of sowing and breeding are pot sown from June to July, using a seedling substrate with peat soil: vermiculite =3:1. Maintain a constant temperature of 20-25℃, cover with a transparent film to maintain 80% humidity. Gradually increase the light after emergence, and bloom can be achieved in 3-4 years. It is recommended to replace 1/3 of the top soil every year to replenish nutrients. In the early stage of pest and insect pest control, the roots can be irrigated with 1000 times liquid of hymoxazole metasol. When scale insects break out, it is recommended to use a combination of spirotetramat + mineral oil to control. Regular wiping of the backs of leaves with 75% alcohol can prevent the growth of pests. Analysis of the Ornamental Value of Purple Root Orchid As a non-toxic flowering plant, Purple Root Orchid is suitable for placing in semi-shaded environments such as living rooms and balconies. The highest flower stem can reach 45cm, and a single plant carries 3-5 flowers, and the flowering period lasts for 20-30 days. The winter dormancy period can be moved to the north-facing window sill, and keeping it moderately dry is more conducive to flowering in the next year.
