Chunlan leaves elegant, blooming fragrance, really lovable. However, the flower arrow is on the short side, mostly lower than the leaf surface, which affects its ornamental ability. So how to make the Chunlan flower arrow relatively higher? I think efforts should be made in three aspects.

First, the preparation of nutritious plant materials is the basis to promote the rise of Chunlan flower arrows. The pregnant bud flowering of Cymbidium consumes a lot of nutrients, and it is impossible to produce a good flower due to congenital deficiency of nutrition. Therefore, whether the nutrition of orchid plant materials is complete or not is related to the degree of flower and arrow elevation of Chunlan. This determines that when we prepare orchid plant materials, we should make great efforts in air permeability, water drainage and nutrients in accordance with the principle of overall consideration. Practice has proved that the preparation of orchid plant material is the best combination of traditional and modern, and the best effect of orchid cultivation is the mixture of sieve orchid mud and granular plant material, which can complement each other with complete nutrients, and provide sufficient power source for the uplift and flowering of spring orchid arrows.

Second, full vernalization and creating an appropriate temperature difference are the necessary conditions for Chunlan flower arrows to rise. Chunlan generally takes nearly half a year from budding after autumn to flowering after spring. in the process of long-term natural evolution, Chunlan has formed the characteristic that only by experiencing the low temperature vernalization in winter can the flower bud expand and the flower arrow be raised. During the period of reproductive growth, if the temperature is on the high side, it is easy to borrow the spring blossom phenomenon, the flowers are covered in the potted noodles, and the flowers are greatly discounted, which seriously affects its ornamental. In this regard, all previous dynasties of Yilan attached great importance to the full vernalization of Chunlan, and advocated that in winter, especially during the period from heavy snow to Greater Cold, the orchid should be kept at a low temperature of 0: 10 ℃, and the temperature difference between day and night should be kept at about 10 ℃, so as to accumulate sufficient nutrients in case the flower arrow blossoms after spring. It can be seen that full vernalization, temperature difference should be appropriate is to promote the spring orchid flowers and arrows in place of the necessary conditions, can not be ignored.

Third, the high humidity in flowering season is the catalyst to ensure the elevation of spring orchid flowers and arrows. Practice has proved that Chunlan keeps a high relative humidity in the air during flowering season, which is very beneficial to the uplift of flower arrows. Lanyou can take a variety of measures such as humidifier humidification, basin water spraying, ground water spraying, flume humidification and other measures to create an air relative humidity of not less than 50%, which can effectively improve the flower and arrow height of the orchid, especially the lotus petal orchid. For example, when the famous products of Chunlan are in the air relative humidity of about 60% and 80%, the flowers and arrows can reach 12 cm and 15 cm.
