Method for regulating butterfly orchid florescence

Abstract

A method for regulating butterfly orchid florescence is characterized by conducting flower induction 20 days earlier than the expected florescence; illuminating the flower for eight hours every day and covering the flower in dark for the rest time; mixing the inner flowerpot substrate of turfy soil with perlite at a volume ratio of 5:1 to 6:1; drenching the whole substrate with clear water with pH value between 6.0 to 6.8; controlling the greenhouse temperature between 8 DEG C to 12 DEG C, the humidity between 70% to 80% in the daytime and 75% to 85% during the nighttime, illumination between 8000 Lux to 10000 Lux; seven days after the first watering, pouring clear water with pH value between 6.0 to 6.8 when the EV value is higher than 0.4, and pouring aqueous solution containing 0.3-0.4g Peters Professional 20-10-20, 0.05-0.06g Peters Professional 15-20-25 and 0.16-0.18g Mg SO4 in every liter when the EV value is lower than 0.4 , and then pouring water solution containing KNO 3 0.8-0.9g / L for one time.

Description

technical field [0001] The invention belongs to the field of flower cultivation methods; in particular, the field of Phalaenopsis cultivation methods. Background technique [0002] Phalaenopsis is a crop of the Orchidaceae Phalaenopsis, native to subtropical rainforests. Avoid extreme heat and dryness, and sufficient light is needed in winter, but exposure to the sun will burn the leaves. The thick white aerial roots of Phalaenopsis are exposed around the leaves, which can absorb nutrients in the air. Some of them cling to the outer wall of the flower pot, which is very natural and wild. The flowers shaped like flying butterflies are favored by flower fans, so they are known as the "Queen of Yanglan". Phalaenopsis likes a slightly acidic, loose and porous, well-drained, water- and fertilizer-retaining air-permeable substrate. The plants are shade-tolerant and heat-loving, so they should be planted in a humid and ventilated environment. [0003] Phalaenopsis is a seedling ...

AI Technical Summary

Problems solved by technology

[0003] Phalaenopsis is a seedling imported from abroad. Because this variety comes from abroad, there is no mature cultivation technology in China, especially in the north of the Yangtze River in China, where the climate is relatively dry, the four seasons are relatively distinct, and the winter is relatively cold. Orchids are prone to deformed flowers, impure flower color, small buds, growth points that cannot produce flowers normally, and cannot make it bloom out of season according to market demand. With the increase in the promotion of Phalaenopsis in China, people have higher and higher requirements for its quality
