First, what kind of fertilizer should be applied to domestic potted orchids?

Fertilizer, to put it simply, is nitrogen, phosphorus, potassium and trace elements. According to personal preferences and culture environment, plant formula is also various, soft, hard, coarse, fine proportion is different, what is discussed here is the soft and hard 2:1, particle 1cm formula, peanut shell + pine bark (coconut shell) + river stone (gravel), this formula is a lot of formula used to raise orchids. There are also 1:1, or soft materials such as whole bark, peanut shell, coconut shell or even stone. What these recipes have in common is light, which can be said to have no fertilizer effect. Therefore, the use of fertilizer is more controllable and the effect is intuitive.

Second, in which season is the orchid suitable for transplanting?

Different orchids have different growth habits, so the time of changing pots is also different. Some productive orchid farms can be changed all the year round because the environmental conditions can be artificially controlled. In addition, some orchids change pots are often combined with ramets, orchids grow after two or three years, when the orchid plants have grown full of pots, then need to change pots, so as not to affect plant growth. It is best for ① orchids to change their pots just at the end of the dormant period when the new buds have not yet germinated, usually once every 2-3 years. National orchids mostly change pots in spring and autumn. The suitable period is from February to April in early spring and from September to November in autumn.

Third, what should be paid attention to in maintenance?

The main results are as follows: (1) Orchid is mainly distributed in southeast and southwest. Most of them are wild in the shade places under the sparse forests and rock edges of the moist valleys, so they like warm and humid climate, like shade and dampness, and require shade of 70% to 90%, avoiding high temperature, dryness and strong light.

(2) the withered and yellow old leaves and disease and insect leaves should be cut off continuously in orchid cultivation to facilitate ventilation. After the flower buds are unearthed, each plant should leave a strong flower bud and the rest should be cut off so as not to consume too much nutrients and affect flowering in the coming year. After the flower fades, the flower stalk should be cut off.

(3) attention should be paid to cold protection in winter, geophytic orchids have strong cold resistance, while orchids require higher overwintering temperature, so they should move indoors or use plastic sheds as soon as possible to avoid cold, and the room temperature should be kept at 10: 15 ℃. Indoor maintenance should pay attention to ventilation. The climate is getting warmer in spring, and gradually move the orchid to the courtyard or balcony.

(4) Natural Rain Water, stream water, well water and river water are the best for family cultivated orchids. If tap water is used, it should be stored in a tank first, and then used after being exposed to the sun to remove bleach. If the flowers are watered with tap water for a long time, the cultivation substrate will be gradually alkalized. Ferrous sulfate can be applied every once in a while to increase the acidity of the soil. in addition, watering orchids with fermented Amoy rice water can also keep the soil slightly acidic.

Fourth, what does the orchid symbolize?

Since ancient times, the Chinese people love orchid, raise orchid, wing orchid, painting orchid, the ancients once had the praise of "watching leaves is better than flowers". People appreciate that orchids live in the company of plants and trees, do not compete with the crowd, are not afraid of frost and snow bullying, and are indomitable and resolute.
