Fertilization of lotus petal orchid

Orchids need fertilizer to grow well, not only organic fertilizer but also inorganic fertilizer. With the application of two kinds of fertilizer, the orchid plant is easy to be strong, the flower blossoms properly and blossoms well. In the past, I always thought that orchids grow in high mountains and deep valleys, and they are a kind of sacred plants. They are flowers of plain elegance and elegance, and they are incompatible with dirty things. It is impossible to have anything to do with fertilizer, and they mistakenly think that they can grow without fertilizer. Topdressing fertilizer is harmful to its quality. Today, the concept of not applying fertilizer to orchids has long been out of date. People in the art and orchid circles have realized the importance of topdressing and fertilizing orchids. In the practice of orchid cultivation in western Yunnan, except for lotus petal orchid downhill grass without topdressing fertilizer, all other ripe grasses should be fertilized with all kinds of fertilizer and water. How to apply fertilizer to lotus petal orchid, what fertilizer to apply, and when to apply fertilizer need to be taken seriously. Lotus petal orchid is cultivated in basin soil, the basin is so large, and the content of soil fertilizer is limited, especially once a year, and most of them are changed twice a year. As a result of the loss of soil fertilizer for a long time, the potted soil can not meet the nutrients needed for the growth of lotus petal orchid. A pot of cultivation material is fertile at first, but because it is often watered, each watering will make the fertilizer lose with the water, so the fertilizer content in the basin soil is gradually deficient. If you use small pots or pottery pots for cultivation, not to mention, the limited fertility contained in the cultivation materials in the pots is naturally even less. In order to change soil infrequently and replenish the deficiency of fertilizer in time, the method of additional fertilization must be adopted. How to apply fertilizer and what kind of fertilizer is still a problem worthy of attention and research. Although lotus petal orchid is a perennial grass plant, but the root is fleshy root, can not directly absorb fertilizer, therefore, the fertilizer must be fermented, and should be thin, must not use raw fertilizer and thick fertilizer. From the results of horticultural research at home and abroad, it is proved that orchids should not only apply organic fertilizer at the right time, but also appropriate inorganic fertilizer. The combination of topdressing and topdressing is helpful to the growth of orchid seedlings and strong orchid trees. According to the summary of most people, there are two ways to apply fertilizer: one is to mix an appropriate amount of fermented organic fertilizer into the culture soil as base fertilizer, and there are also fertilizers sold on the market as base fertilizer, which can be mixed into the culture soil when in use. the fertilizer effect of base fertilizer is long, and the management is time-saving and time-saving. Second, in the orchid seedling growth period topdressing, that is, the use of fermented fertilizer diluted directly into the basin, inorganic fertilizer can also be used to irrigate the basin or spray leaves. It is best to use leaf spray insurance after dilution of inorganic fertilizer. The organic fertilizer applied, whether as base fertilizer or topdressing fertilizer, must be fermented thoroughly for a long time, otherwise it will be counterproductive or ineffective. The application of inorganic fertilizer must pay attention to dilution, must not apply thick fertilizer, otherwise the consequences are unimaginable. Fertilizer should be paid attention to, thin fertilizer frequently, according to the needs of orchid topdressing all kinds of fertilizer, fat orchid can not be thin for a long time, thin disease orchid plant had better not apply fertilizer. If there is too much topdressing fertilizer, it will cause fat injury to the orchid plant, and it will not be able to recover several years after the fertilizer injury, and in the serious cases, the plant will die and the stem will wither. What kind of fertilizer should be applied to lotus petal orchid? The inorganic fertilizer with stable quality produced by the factory can be used boldly, but there are many kinds of organic fertilizer, such as sheep manure, chicken feather water, fish scale rotten water, sesame water and so on, which can be prepared separately or mixed. Inorganic fertilizers must contain chemical fertilizers containing nitrogen, phosphorus, potassium and other trace elements, such as compound fertilizer, potassium dihydrogen phosphate and so on. For different growing periods of orchids, different kinds of fertilizers are used, or mixed into appropriate proportions. According to the Collection of Horticultural Tips published in Japan, perennial grass flowers are mainly ornamental plants, and it is most appropriate to use one part of nitrogen, two parts of phosphorus and three parts of potassium. It should be pointed out here that in balcony and indoor cultivation of lotus petal orchid, the light is insufficient, the degree of emptiness is poor, the air permeability is insufficient, and the root system is underdeveloped, so applying a little more potash fertilizer can help new seedlings grow roots. The application of potash fertilizer can rest assured that potash fertilizer, like phosphate fertilizer, is a kind of long-acting fertilizer, and more application will not produce side effects.
