Simple Management of National Orchid (2)

Chinese orchid is a fertilizer saving plant. It can grow normally without fertilization all year round. This may be due to the stomata on orchid roots and leaves obtaining some fertilizer and trace elements from air and water. However, if appropriate fertilization is carried out, the growth of Chinese orchids will be significantly promoted, such as vigorous new shoots, oily green leaves, rapid growth and easy flowering. Orchids with a lot of fertilizer names, such as flower treasure, Xi Shuo, multi-wood, plant and so on. The contents of nitrogen, phosphorus, potassium and trace elements in various fertilizers are also different. Some brands also have different models due to different fertilizer effects, such as some suitable for germination, some suitable for long leaves, and some suitable for flower promotion. Here, I only talk about some popular prices, and simple and practical Lan Fei. In the spring germination period, can apply 500 times orchid fungus king to irrigate, also can foliar spray and irrigate, spray and use. Lanjunwang is a kind of germinating agent, but it contains enough nitrogen, which has good effect on germination, rooting and long leaves. In the growth period, 500~1000 times of potassium dihydrogen phosphate containing sufficient nitrogen and various trace elements can be sprayed on the leaves, and it can also be used as the king of orchid bacteria. The leaves grow fast and strong, and the effect is good. After autumn cool, spraying pure potassium dihydrogen phosphate 500~1000 times without other components on leaves can strengthen pseudobulbs and promote flowering.

There is no hard and fast rule on the frequency of fertilization. Generally, 2~3 times in germination period, 4~6 times in growth period, 2~3 times in flower and strong stem period. The standard of fertilization mainly depends on leaf color and growth. If the leaves are green enough and growing vigorously, fertilization can be suspended or supplemented later when necessary. If excessive fertilization, it will cause adverse effects, such as bud, tender leaves injured, line art decline, only long leaves without flowering and so on. Fertilization should be carried out in the morning with sunshine, which is conducive to photosynthesis of orchid plants; after spraying, 4~6 hours can be washed with water (orchid king irrigation can be kept for 3~5 days), in order to ensure safety.
