Excellent potted orchids not only have strong roots and lush leaves, but also have high ornamental value and artistic charm. How to cultivate strong roots is the first problem we need to solve, because the quality of roots will directly affect the growth of orchids, and even determine the embodiment of ornamental value. So, how do potted orchids raise their roots? After practice, Bian Xiao summed up a set of relatively complete root-raising techniques, and now he shares them with you.
First, planting materials
Good planting environment is the basic condition for cultivating strong roots of orchids, and local culture is recommended. But after all, as a family potted orchid, the conservation environment cannot be compared with the growth environment in the wild, and it is even more impossible to move the family potted orchid to the wild for conservation and management. Therefore, we can only prepare planting materials according to the angle suitable for the growth of orchid plants.
The plant materials for orchid cultivation should be fertile, loose, breathable and permeable, and keep water and fertilizer. As long as we can create such a growth environment for them, it usually provides good basic growth conditions for orchid plants. Specifically, we can prepare orchid planting materials according to the following scheme:
Select plant stone, fairy soil, humus soil, bark block and firewood, and then prepare them according to the ratio of 3:4:2: 1. As long as we can prepare plant materials strictly according to this method, we can create a good environment for orchid plants to promote, protect and strengthen their roots.
Second, fertilization.
Fertilization is also very important for orchid cultivation, because the application of fertilizer will directly affect the germination and growth of roots. WWw.pjcN.oRg needs to supplement appropriate amount of phosphorus and potassium fertilizer, which is the main nutrient for cultivating orchid roots. The recommended practice is:
1. The plant material of orchid flowerpot is mixed with proper amount of substances such as bone powder to supplement phosphorus and potassium fertilizer, which is also used as base fertilizer.
2. Use some potassium dihydrogen phosphate for watering at ordinary times. Diluent should be prepared before use, and the PH value should be ensured to be between 5.5 and 6.5, so that there is dilute phosphorus and potassium fertilizer in the water, and the dilute fertilizer should be applied frequently to achieve the purpose of strengthening roots.
3. In the process of topdressing, a small amount of potassium dihydrogen phosphate should be used as the main nutrient of strong roots.
Third, dry farming
Ancestors have a saying that "wet long buds dry roots to promote roots." Spring is the peak season for orchid growth, so the humidity of the growth environment can be appropriately increased to promote orchid plants to sprout new buds. When the new buds grow to a certain height, watering can be properly controlled to keep the plants dry. The main purpose of this is to promote the germination and growth of new roots of orchid plants. More importantly, this method can make young orchids get rid of old orchids safely and smoothly and keep healthy growth alone.
Fourth, pruning
Orchid planting needs to turn over pots regularly, or even change soil, and usually needs pruning when replanting pots. The purpose of this is to promote orchid plants to germinate new roots by cutting off old, weak, diseased roots and small roots, improve the absorption capacity of roots, and is also very beneficial to promote plant germination and leaf extraction. This is what we often call the theory of pruning roots and promoting buds.
In short, the root of raising orchids is to promote buds. Only when the roots of orchids grow strong and cultivated well can the leaves spread out and make potted orchids look strong and flourish. It can be seen that raising roots is of great significance to raising orchids.
