Now is the season when orchids bloom, bud and grow vigorously, and everyone must take good care of their orchids, hoping that they can thrive and bloom beautifully. In the process of orchid growth, the application of nitrogen fertilizer is a very critical part, but it is also a headache for many flower lovers. Today, we will talk about the selection and application skills of nitrogen fertilizer for orchids.
First of all, we need to clarify the role of nitrogen fertilizer in the growth of orchids. Nitrogen fertilizer is one of the indispensable nutrients for the growth of orchids, which can promote the growth of orchid leaves, making them more green and lush. However, too much nitrogen fertilizer application can also bring a series of side effects, such as seedling burning, growth, poor stress and lodging resistance, and even pests and diseases.
So, what kind of nitrogen fertilizer should we choose? There are many types of common nitrogen fertilizers on the market, such as urea. However, the concentration of this type of nitrogen fertilizer is difficult to grasp, and the slightest carelessness may cause damage to orchids. Therefore, I am more inclined to recommend everyone to use nitrogen fertilizers such as soybean cake fertilizers, such as the cake fertilizers we often say. Cake fertilizer is not only rich in nitrogen, but also has a mild and long-lasting fertilizer effect, which is more suitable for the growth needs of orchids.
Of course, there is also a problem with cake fat, and that is taste. Unfermented cake fat often emits an unpleasant odor that is unacceptable. During the orchid growing season, spring and autumn, sprinkle the cake fertilizer evenly on the surface of the pot. Be careful not to use too much, sprinkle a small circle every season is enough. This not only meets the orchid's need for nitrogen fertilizer, but also does not cause harm due to overapplication.
In addition, it should be reminded that while applying nitrogen fertilizer, it is also necessary to pay attention to the combination of other fertilizers. Orchids need not only nitrogen, but also phosphorus, potassium and other nutrients during their growth. Therefore, according to the growth stage and needs of orchids, we can reasonably use compound fertilizers or organic fertilizers to ensure that orchids can absorb nutrients in a comprehensive and balanced manner.
