Under the conditions of suitable temperature, humidity, light and reasonable nutrition, most species of Chinese orchids can grow 2 or 3 times of new buds. Usually under suitable growth conditions and environment, it takes about 90 to 120 days for Chinese orchid to sprout to form a plant. People found in the cultivation of orchids: where new buds were unearthed at the beginning of April, the second new buds were unearthed in mid-late June. The first batch of new buds basically matured after 90 days of growth. The second batch of new buds also formed strong plants after 120 days of growth from July to October. It is theoretically possible to calculate the growth of three batches of new buds in 365 days throughout the year. In fact, however, this is not the case, because the seedlings in the next year are often not strong enough, and they have to continue to grow next spring, delaying the germination of new buds until May to June. When the new buds were unearthed and grew in the high temperature season from July to September, the orchid plant grew slowly. After summer and short autumn, after mid-November, the temperature is getting lower and the orchid vegetative growth is slow, so that after a year, immature new seedlings have to wait for the coming year. Year after year, a batch of seedlings fail to grow. It can be seen that the germination of new buds of orchids is related to the climatic conditions suitable for the growth of orchids. The number of new buds sprouting depends on the number of days in a year that are suitable for orchids to grow reasonably. The more days provided, the more batches sprouting will be. In the middle and lower reaches of the Yangtze River, there are 24 solar terms in a year. In normal years, Grain Rain to the Summer Solstice is more suitable for orchid growth, a total of 75 days. White Dew to Cold Dew a total of 45 days, also suitable for orchid growth, a total of 120 days, these time is enough for orchids to grow into seedlings. The reason why seedlings can not grow to maturity once a year must be due to problems in management and cultivation. In fact, it is not difficult to grow 2 batches of seedlings a year. If we can make use of 30 days in early spring and 60 days in summer (using artificial cooling), we can obtain another batch of seedling growth cycle. Therefore, improving the environment of orchid cultivation and artificially creating a microclimate suitable for orchid growth can make orchids sprout more.

How to make orchids not only grow more seedlings, but also bloom more, which is actually a problem of scientific management. In the process of cultivating Cymbidium for many years, the author thinks that there are many factors that affect the flowering of Cymbidium, but the most important one is to master four main links, namely: cultivating strong seedlings, increasing light, reasonable fertilization and watering.

First, cultivate strong seedlings. In general, the spring orchid for ornamental flowers cannot be divided into single seedlings for propagation. It is best for three seedlings to be connected to the pot, so that strong seedlings can be cultivated.

Second, increase the light. Light is the main factor affecting the growth and flowering of orchids. Plants rely on sunlight for photosynthesis to produce indispensable nutrients for their growth. The growth of Cymbidium and the formation of flowers need sufficient light. Sunlight can help orchid leaves carry out photosynthesis, make food, and support the growth and flowering of orchid seedlings. In addition to summer and early autumn, Chunlan can not let direct sunlight in other seasons, which can not only make the orchid seedlings healthy and strong, but also strengthen the bulbs and promote the propagation of buds. Orchids with exuberant growth are easier to draw buds.

Third, rational fertilization. The accelerated growth and bud development of Cymbidium depend on fertilization, so it is important to apply appropriate amount of fertilizer at the right time. Fertilization should vary according to the growth period of orchid plants. Chunlan has two main growth periods, namely vegetative growth period and reproductive growth period. For new buds and seedlings, before the bulbs grow to semi-mature, most of the nutrients made by photosynthesis are used for the growth of orchid plants, but less storage, this is the vegetative growth period, during this period, the fertilization should be slightly more, and the phosphorus and potassium fertilizer should be less to make the plants grow. The vegetative growth period is generally from the end of April to the beginning of July, and fertilizers with high nitrogen content should be applied every half a month. The vegetative growth period is followed by the reproductive growth period, when sugars and proteins made by photosynthesis are stored in the bulbs and leaves for flowering or new bud growth, during which there must be more phosphorus and potassium fertilizer. The reproductive growth period is generally from the middle of July to the end of August, and fertilizer with high phosphorus content should be applied every half a month.

Fourth, master watering. Water is one of the material bases for plant growth, but there should be a limit to the amount of water. Watering should not be fixed for a fixed time, but should seize the opportunity. If it is dry, it will be watered thoroughly, and when the orchid basin is dry, it will be watered. This is the basic principle of watering. When watering, it should be noted that the temperature of the water should be similar to that in the orchid basin of the orchid place as far as possible. Summer and early autumn can be watered in the morning and evening, while in winter at noon, the aim is to reduce the temperature difference between water and orchid pots. Spring orchids should generally be watered during the growing period, and watering should be strictly controlled before flower buds are formed.
