The Culture method of Magnolia

Magnolia is native to the tropical regions of southern Africa and grows under trees, so it is not only afraid of heat but not cold-resistant, like semi-shady and humid environment, afraid of strong direct sunlight, the best temperature for growth is between 18 and 28 ℃, below 10 ℃, above 30 ℃, and growth is inhibited. Cymbidium likes a ventilated environment, likes deep, fertile and loose soil, and is suitable for growing in loose and fertile soil with slightly acidic organic matter. Cymbidium is a famous greenhouse flower and is suitable for indoor culture. the breeding methods of Cymbidium are introduced as follows:

The Propagation method of Cymbidium

The propagation methods of Cymbidium are commonly used in sowing and ramet reproduction.

1. Sowing and breeding method

The method of pollination is as follows: 2-3 days after perianth cracking, when the bud matures and the stigma secretes mucus, it is the time for pollination. During pollination, the pollen of stamens is dipped with a new brush and gently falls on the stigma of the pistil. In order to increase the seed setting rate, the seeds can be pollinated once between 9: 10 a.m. and 2: 3 p.m., and the seeds can mature after about 8 to 9 months. When the pericarp gradually changes from green to black-purple, the ear can be cut off and the seeds will be peeled off after 10-20 days. Before sowing, soak the seeds in warm water of 30: 35 ℃ for 20 / 30 minutes and then dry them for 1 / 2 hours (it is better to soak them in 10% sodium phosphate solution for 20 / 30 minutes and then soak them in clean water for 10 / 15 hours), then sow them into the culture soil. The flowerpot after sowing was placed in an environment with a room temperature of 2025 ℃ and a humidity of about 90%, and the radicle germinated in about 1-2 weeks.

The cultivated soil should be prepared before sowing and breeding. There are many materials available for making culture soil, but one of the more easily obtained is loose soil with sufficient humus taken from the surface of the forest, mixed with clean fine sand soil of 1 stroke 3.

2. Ramet breeding method

The asexual reproduction of flowers has the methods of cutting, ramet, striping, grafting and so on, but the asexual reproduction of Cymbidium is generally only the method of dividing plants, and this method is more common. To propagate by dividing plants, you must first do some preparatory work:

① family potted plants to prepare flowerpots, flowerpots had better be earthen pots, do not buy porcelain, ceramic pots with beautiful surface, because their poor air permeability is not conducive to plant growth.

② prepares the medium soil, it is best to disinfect it. If humus soil is mixed with fine sand, humus soil should be sprayed with potassium permanganate 1000-2000 times aqueous solution to disinfect; fine river sand should also be washed and disinfected with boiling water to prevent seedlings from being infected and rotted by germs.

③ prepare a little charcoal powder to smear the wound for moisture absorption to prevent decay.

④ sharpens the knife used for cutting, and finally quickly dry grinds (without adding water) dozens of times on the grindstone to make the blade highly hot to kill germs.

When the orchid divides, first bring the mother plant of the orchid from the basin, remove the resident soil, and find out the buds that can be divided. If the daughter plant is born on the outer edge of the mother plant and the plant is small, you can hold the bulb in one hand and the base of the child plant in the other hand and tear it off; if the daughter plant is strong and not easy to break off, it should be cut off with a prepared sharp knife. Never break it by force, so as not to damage the young plants. After cutting off the offspring, you should immediately smear the wound with dried charcoal powder to absorb the fluid and prevent decay. Next, the seed plant is planted in a pot. When planting, the planting depth is to bury the false bulb at the base of the seed plant, make it slightly higher on the part of the seedling plant, and cover it with sterilized sand. Immediately after planting, pour water once, and then cover with a layer of culture soil when the wound heals 2 weeks later. It usually takes 1-2 months to grow new roots and blossom for 1-2 years. The heredity of the magnolia propagated by the split method is relatively stable and can maintain various characteristics of the original species.

The culture method of gentleman orchid is divided into soil culture method and water culture method. Let's take a specific look at these two culture methods.
