Proper ramet and reasonable soil exchange

How to divide the orchid plant is appropriate, when to change the soil is reasonable, the practice of the orchid boundary, the eight Immortals cross the sea, each show their magical powers, justice, mother-in-law, each hold their own opinions.

Some people advocate changing the soil of orchids year after year. It is said that planting into individual plants can increase the proliferation rate, and changing soil every year can increase soil fertility. Lan Zhaoyun: "Lanxi cluster, do not plant alone." Single plant planting, especially male plants, can promote leaf buds, but if a single plant is not strong or nutrients do not keep up, the germinated leaf buds are mostly weak seedlings. The proliferation rate of orchids can not be improved if there are many buds and weak seedlings, but only strong buds can really improve the proliferation rate of orchids. However, the specific situation must be analyzed concretely. Some varieties with high germination rate, such as Golden Horsetail, can be planted with strong seedlings. It is not necessary to change soil year after year, but the key problem is that the selected medium contains enough fertilizer and does not contain a wide range of fertilizer. As long as the plant material is selected properly and the proportion is scientific, a pot of orchids has enough nutrients to supply orchids for three years. Every time the orchid changes the soil, it takes half a month to a month to take the pot. If the soil is changed frequently, the root system will be damaged, the growth of the aboveground part will slow down, and the absorption function will be weakened, which is not conducive to the growth of orchid plants. If the pot is too wet or other reasons lead to rotten roots and withered leaves. Cause diseases, such as white silk disease, weigh the pros and cons, then it is necessary to turn the basin and change the soil immediately.

In order to change the soil, the author's practice is as follows: 3murine 6 conjoined clumps, each pot with a diameter of 20 cm, choose the above-mentioned planting formula, and change the soil once every three years. In order to promote the dormant bud germination of the pseudobulb, the joint of the pseudobulb of the father plant and the mother plant can be moved slightly into a semi-separated shape, so as to accelerate the germination of the plant, cut off the old and residual leaves of the plant, and slow down the growth of the underground part and promote the growth of the aboveground part.
