Five measures for orchids to promote fragrance

The fragrance of orchids in nature is full of fragrance, refreshing and has the reputation of "fragrance of kings", which is favored by the world. For thousands of years, people praise orchids and love orchids. Her charm lies in her delicate fragrance. If there is no fragrance, it is not desirable. Therefore, how to make the fragrance of potted orchids sow year after year has become a hot topic for orchid friends. According to my practice, I think we should pay attention to the following five problems. First, plant materials should be rich in nutrition, and it is best to use improved orchid mud to raise orchids. With the wide application of artificial granular plants, chemical fertilizers and modern greenhouses, the propagation speed of orchids has been significantly improved, and the situation is gratifying. Happy, orchid friends found that the attractive fragrance of orchids is also less and less. To investigate the reason, orchid planting is an important factor. For thousands of years, people have been planting orchid trees with orchid mud. As long as they are planted and cultivated properly, they will have their own fragrance every year. In order to better solve the problem of aeration and drainage of plant materials, modern people keep pace with the times and produce a variety of granular plant materials, which is a great progress in history. Due to the general lack of nutrition of artificial granular plant materials, people have used modern science and technology to produce all kinds of orchid fertilizer to make up for its lack of nutrients and achieved good results. However, artificial chemical fertilizer can not fundamentally solve the large number of trace elements and minerals needed for the growth of orchids. Therefore, the flowers, especially the delicate fragrance of orchids, are affected to varying degrees by simply using artificial granular plants and chemical fertilizers to raise orchids. Practice has proved that the best combination of modern and traditional orchid, sieve orchid mud and artificial particle plant mixed orchid, Lanhui strong, beautiful color, fragrance overflowing, the effect is the best. Second, appropriately increase the light, let orchids bask in the sun and all things grow on the sun, and orchids are no exception. The nutrients needed for the differentiation and opening of orchid flower buds are produced by photosynthesis. If the light lasts for a long time, photosynthesis produces more nutrients and the fragrance of flowers is strong. Such as lack of light, although the plant grows luxuriantly, but due to the production of few nutrients, orchids rarely blossom, even if flowering, it is not good, the smell is mediocre. This is also proved by the fragrance of orchids in places with plenty of light in the natural mountains and forests. Therefore, increasing the light appropriately and letting the orchids bask in the sun in spring, autumn and winter are the necessary conditions for orchids to blossom and give off fragrance. Third, strive to create a suitable temperature difference. Most orchids in nature grow in lush forests and valleys. Because there are many trees, good ventilation and high elevation, even in hot summer, the night is relatively cool, and the temperature difference between day and night is generally about 12 degrees. It is very conducive to the storage of nutrients. The growth of orchids is the unity of photosynthesis and respiration. On the one hand, orchid plants continue to produce nutrients through photosynthesis during the day; on the other hand, orchid plants continue to breathe day and night, consuming nutrients, the higher the temperature, the more nutrients are consumed, and the lower the temperature is, the less nutrients are consumed. Only when the nutrients produced by photosynthesis are greater than those consumed by respiration can orchids blossom and give off fragrance. It can be seen that the necessary temperature difference is an indispensable condition for orchids to be self-contained. Fourth, Lan Hui needs to fully vernalize the reproductive growth of orchids has its special law, we can not violate it. The winter temperature of wild orchid is generally between 0 and 15 degrees. Although orchid seedlings do not grow, buds continue to grow and enrich, accumulating nutrients to prepare for flowering. This is an insurmountable stage for orchid flowering. If the winter temperature is on the high side and vernalization is not sufficient, Lanhui will appear stiff buds, even if it blossoms, the flowers are poor and the fragrance is light. I have a deep understanding of this. Last year, I had five famous Huilan products, and I couldn't help rejoicing. In order to prevent freezing, put it on the windowsill of the living room with plenty of heating and sunshine, the all-day room temperature is generally about 18 degrees, the result is contrary to one's wishes, not a pot of flowers, but the seedlings grow well. The reason is that it has not been fully vernalized. Fifth, the practice that the pot soil should be moist and dry when the orchid blossoms proves that the dry humidity of the pot soil is also one of the factors affecting the orchid blossom and flower fragrance. Generally speaking, moderately let the orchid dry, the orchid fragrance is thicker, on the contrary, the aroma is insipid.
