Interpretation of nitrogen Fertilizer

[nitrogen) is one of the main elements in the growth of Cymbidium. Nitrogen is the synthesis of chlorophyll and is an important material for protein, nucleic acid and organic matter, which is very important to promote the growth of Cymbidium.

The main function of nitrogen is to promote the elongation of stems and leaves, exuberant growth, luxuriant stems and leaves and so on. Usually during the growth period of national orchid, such as insufficient supply of nitrogen, it is often easy to cause leaf yellowing, the new buds will be short and thin due to lack of nitrogen, and the number of leaves will be relatively reduced. When it matures, the bulb is small, the disease resistance is weakened, it matures earlier, and sometimes blossoms earlier. When there is too much nitrogen supply, the tissue is weak, the stems and leaves grow and droop, the disease resistance is reduced, the mechanical support is also weak, the maturity is delayed, the leaves are dark green, and the quality and yield are greatly reduced. If nitrogen can be fully supplied under appropriate conditions, the ability of absorbing nitrogen and the production of nitrogen-containing substances such as protein will be greatly improved, the leaf area and organic products, chlorophyll content and photosynthesis will increase, and promote the rapid growth, quality and yield of Orchid plants.

Nitrogen fertilizer can be divided into "organic matter fertilizer" and "chemical fertilizer". Generally, organic matter is slow-acting and mixed with the medium in the Guolan basin, which can be absorbed and utilized by the microorganisms in the medium. Such as chicken manure, pig manure, bean cake, fish meal, etc.; effective fertilizers are commonly found under chemical fertilizers, such as Lancondo and LanWorld Live yeast Fertilizer (BKC). The fertilizer effect is as long as 3 Mel for 6 months. And quick-acting fertilizers. Such as Mulah liquid, Aisheng orchid and so on, can be absorbed and utilized by Guolan after being applied to Guolan plant.
