Propagation methods of White Orchid

White orchids are famous ornamental flowers and trees, white and elegant colors, charming fragrance, long flowering period, dense green branches and leaves, with very high ornamental and beautification value, relatively simple maintenance, propagation methods are also relatively many, more used is grafting and layering methods, and sowing and cuttage are used less, but family breeding is used, grafting method and layering method are enough.

Magnolia seed propagation

Sowing and seedling raising are carried out at the end of September or the beginning of October, mature fruits are collected, seeds are taken out, soaked in plant ash water for 1-2 days, waxy aril is rubbed off, and then seeds can be sown after washing, and then the seeds can be refrigerated by wet sand stratification method, otherwise the seed germination ability is easily lost, and the seeds are sown in indoor pots in March of the next year, and the seedlings can emerge after about 20 days.

Cuttage propagation of white peony

White orchids can be propagated by cuttage, but the ability of white orchids to reproduce is poor, and it is not easy to root and survive by cuttage, so it is not adopted.

Grafting propagation of white peony

White orchids are propagated by grafting method. Generally, 2-3 years old of magnolia flower and yellow orchid are used as rootstock. There are two grafting methods in grafting method, one is close grafting and the other is cutting grafting.

1, close to: close to the time, from spring to autumn, the entire growing season can be carried out. Most of them are carried out from April to July. 70 cm from the ground is the best place to abut. After binding, wrap it in mud and wrap it outside with leaves to prevent rain washing. After about 60 days, it can be cut off. It is easier to survive by joining, but it is not as vigorous as cutting.

2. Cutting and grafting: in the middle and late September, select well-developed magnolia branches as scions, the cut surfaces of rootstocks and scions should be closely combined, bound and smeared with plastic film strips, and the scions buried in soil to keep the soil moist. In northern China, scions should be covered with straw in winter, and the covering should be removed in the spring of the next year. After germination, 4-5 buds on the upper part of the branches should be retained, and the rest buds should be removed. After 2-3 years of routine maintenance, they can bloom.

White orchid layering propagation

White orchid layering propagation is also used more propagation methods, mainly divided into ordinary layering and high-branch layering.

1, ordinary layering: ordinary layering is best carried out in 2-3 months, the base of the branches to be pressed into half depth, and then cut up a section, the middle card a tile, and then gently pressed into the soil, do not break, with "U"-shaped thick iron wire inserted into the soil, fixed to prevent tilting, and then piled on the soil. Spring layering, to be sent out after the root bud can be cut off sub-planting.

2, high branch layering: before entering the ambush, select healthy and disease-free shoots (1.5-2 cm in diameter) on the mother plant, cut cracks in the lower part of the basin fork, and then cover it with bamboo tubes or bottomless pots, filled with culture soil, tied with strings outside, careful not to touch, often spray a small amount of water, keep it moist, new roots can be produced around May of the next year, and take down the planting.
