Fertilization Technology of Cymbidium
Hanging orchid, people call it "flowers in the air", the flowerpot on the balcony, railing, and other potted flowers can be reflected up and down into interest, very beautiful. The hanging orchid is also a natural scavenger, which can remove harmful substances from the air. Some studies have shown that the orchid can absorb more than 80% of the indoor harmful gases and has a strong ability to absorb formaldehyde. The engineer of the Indoor Environment Monitoring Center of China Decoration Association believes that the orchid is one of the most suitable plants to be placed in the room.
Cymbidium is a more fertilizer-tolerant foliage plant, if the lack of fertilizer and water, it is easy to scorch head aging, leaves yellowing, loss of ornamental value. From late spring to early autumn, Gymboree seaweed fertilizer and organic fertilizer can be applied every 10 days, but less nitrogen fertilizer should be applied to Phnom Penh, Jinxin and other mosaic varieties, lest the color of flowers and leaves fade or even disappear, affecting their appearance. The retting organic fertilizer such as bone meal and eggshell can be properly applied, and after being fully fermented by Gymboree starter, appropriate amount of diluent can be taken and poured once every 15 days to make the flowers and leaves bright and bright.

Fertilization technology of rhododendron
Cuckoo root is delicate, fertilizer must be cooked before it can be used. Generally, it is more suitable to use retting fertilizer which has been fully fermented for more than one year. Five points should be paid attention to in fertilizing: look at the seedlings to fertilize. The seedlings can not be fertilized, and the liquid barnyard manure which is well retted and extremely thin can be applied after 4 months. After the plants are set and planted in the next spring, more nitrogen and potassium fertilizer should be applied to accelerate vegetative growth. Phosphate fertilizer should be applied in 2 ~ 3 years of adulthood to make the flower rate high and the flower large and colorful. In the old age, more nitrogen fertilizer can be applied to promote the renewal of branches and leaves, rejuvenate the tree and prolong the age of the tree. Fertilize at the right time. Morning

Measures of fertilization and watering of alpine rhododendron
There are many theories about the fertilization of alpine rhododendron. From our practice in recent years, we should change our traditional centralized fertilization method and replace it with "thin fertilizer application frequently", that is, balanced fertilization for each watering, paying special attention to the ratio of N:P:K in different growth and development stages. Because of its great influence, we should try our best to carefully detect and analyze each watering in order to prepare the most ideal pH value and EC value. We have done a lot of experiments at different growth stages, such as 12 gradients from pH3.8 to 7.1.
