Propagation methods and matters needing attention of yellow orchid

Yellow orchid has high ornamental value and is a flower-scented plant. Its flowers and leaves can be used to extract aromatic oil. The cultivation of yellow orchid is not difficult, but in the north of our country, we should pay attention to greenhouse or pot ornamental, so as to avoid frostbite in winter.

Yellow orchid

Magnolia reproduces mainly by sowing and can also be grafted. When the seeds just crack and appear red, they should be harvested in time and stored in sand to be sown in the spring of the following year. It usually begins to sprout about 1 month after sowing, but it also takes nearly 2 months to sprout. Seedling transplanting should be carried out in the evening or cloudy days. After transplanting, a shade shed should be built, and the shed should be removed gradually after the plant grows tall. The maximum height of one-year-old seedlings is 40cm to 50cm, and the crown is 40cm, which is better than that of grafted seedlings. Grafting, can use Tianmu Huanglan, Huangshan Huanglan and so on as rootstocks. The cultivation and management of yellow orchid is the same as that of white orchid (details). The main pests are scale insects, which should be controlled in time.

1. Morphological characteristics.

Deciduous trees, 10m high. The leaf is 10~20cm in length and 4~9cm in width, and the leaf margin is wavy: the stipule marks are above the middle of the petiole. Flowers solitary leaf axils, caseous yellow, extremely fragrant. 2. Cultivation techniques.

[seedling cultivation] this kind of plant is mainly propagated by high pressure, which is mostly carried out from April to May every year. Cutting, striping, grafting and other methods can also be used to raise seedlings.

[cultivation substrate] the slightly acidic loam rich in humus should be selected. It is not suitable to plant in saline-alkali soil.

[planting method] when planted on the ground, yellow orchid seedlings are mostly planted in spring. You should choose a place with high terrain and plenty of sunshine. The hole can be dug according to the size of 60 cm in diameter and 60 cm in depth. It is best to apply barnyard manure in the hole and pay attention to cover it with subsoil so as not to burn roots. Usually put a three-year-old seedling in each hole, first straighten it, spread the roots, and then fill the soil and step on it. Then water thoroughly once, and after 3-5 days, you need to pour two more water. The colonization operation is best carried out on cloudy days.

[key points of management] Huang Lanxi was watered once after planting in the soil environment where the micro-tide was partial to one F. Watering management should be strengthened before the seedlings grow new leaves, so that the soil should not be dried. In the future, as long as the soil is not too dry, we can basically use natural rainfall to supply water. In addition to applying rotten leaves as base fertilizer before planting, liquid fertilizer rich in nitrogen, phosphorus and potassium should be applied once a week during the vigorous growth season. In the whole growth process, we should ensure that there is appropriate direct sunlight, receive direct sunlight should not be less than 4 hours a day, to avoid environmental shade. The environment should be ventilated so that photosynthesis can proceed smoothly. Huang Lan likes to be warm and avoid severe cold. It grows well in the temperature range of 20-30 ℃. The overwintering temperature should not be lower than 5t and can withstand short-term low temperature of 0 ℃. The weak, withered and thin branches of yellow orchid should be cut off at any time. In actual cultivation, yellow orchid will be attacked by Rhizopus, black spot and other harmful animals, such as diamondback moth, brown aphid, dragonfly and so on.

[planting years] this plant is perennial and takes 6 years from reproduction to formation. The viewing period can be up to 20 years or even longer after forming, so it takes a long time to plant in situ.

3. Distribution area

Native to the Himalayas, southern China, India, Java or Malaysia, Taiwan was introduced in 1800 and is now cultivated sporadically.
