It is important to master the correct fertilization methods in orchid fertilization.

Orchids should pay attention to fertilization, and mastering the correct fertilization methods can make orchids grow more frequently and grow vigorously. Generally speaking, orchid fertilization is not essential, and it should be comprehensively considered in combination with the seedling condition, growth characteristics and other factors of orchids. Any fixed fertilization method is not comprehensive. Combined with years of experience in orchid cultivation, Lanxiang Pavilion is summarized from three dimensions:

1. How to apply fertilizer from the perspective of the four seasons: in the four seasons of the year, spring is a vigorous period for growth and reproduction, high temperature in summer is not conducive to growth, autumn will usher in a strong seedling stage, and winter is a dormant period. After mastering this law, let's study the problem of fertilization. the plan for the year is to apply more fertilizer in spring to promote more and stronger seedlings of orchids; it is rainy and hot in summer and the growth of orchids is hindered, so do not apply more fertilizer at this time, otherwise it is easy to cause high temperature fertilizer injury; orchids are in the strong seedling stage in autumn and store nutrients for winter and flowering, so it is necessary to apply fertilizer in time to ensure the growth of orchids, especially more phosphate fertilizer. Orchids are dormant in winter and can survive the winter safely without fertilization.

2. How to apply fertilizer from the growth cycle: the important growth cycle of orchids, the types and methods of fertilization are different. The growth cycle is divided into three important stages: seedling stage, flowering stage and dormant stage. Although different varieties of orchids, the time of the three stages is different, but the growth law is the same, so the fertilization method is also the same. An orchid at the seedling stage. Fertilizer can be applied relatively more. In particular, to strengthen the supply of nitrogen fertilizer; flowering should be fertilized in advance, generally two months before flowering to increase the supply of phosphate fertilizer, phosphate fertilizer can promote the growth of orchid buds, enhance orchid flowers; dormant period generally does not recommend fertilization, orchids already like list fertilizer, especially in the dormant period, can not be fertilized at all.

3. How to apply fertilizer from the point of view of the types of fertilizers: the fertilizers used for orchids are: chemical fertilizer, typical representative is potassium dihydrogen phosphate, which is generally used for spraying leaves, to enhance leaf color and promote flowers; biological fertilizers, typical biological fertilizers include soybean water clarification solution and Amoy rice water clarification solution. When using these fertilizers, attention should be paid to sterilization and disinfection, and the concentration should be mainly based on the list. Slow-release compound fertilizers are typically represented by Huakang and Haokangduo, which are characterized by long effect and comprehensive nutrition, so they are recommended to be used as base fertilizer.
