How to cultivate and maintain the magnolia by hydroponics?

Gentleman orchid, alias sword leaf Lycoris. Belong to the genus Amaryllidaceae. Is a perennial evergreen herb. The plant height of Cymbidium is 30-60cm. The root system is stout and fleshy. The stem is divided into two parts: rhizome and pseudobulb. Leaves from pseudobulbs, sword-shaped, leathery, dark green. Umbels, florets 10 to dozens; Corolla funnel-shaped, erect, orange-red. The fruit is a berry, purplish red when ripe. The florescence varies according to the variety, winter, spring or spring or summer. There are three kinds of plants of the same genus: orchids with large flowers, orchids with hanging flowers and orchids with narrow leaves. The flowers are delicate and beautiful, dignified and elegant; the leaves are green, thick and shining, which can be described as beautiful flowers and leaves.

1. Hydroponic method

The main results are as follows: (1) the whole seedling of Cymbidium was dug up and carefully stripped off the corpse next to the mother plant to form the large tiller bud to protect the root system of the bud. After rinsing with clean water, it was planted in a transparent container, and water was injected into 3 places of the root system, and the water was changed once every 2-5 days. The hydroponic magnolia is shown in the picture.

(2) in the second method, the 2-3-year-old magnolia was cultivated in soil, the whole plant was dug up, the rotting root system was removed, washed and disinfected with clean water, and the whole plant was planted in a transparent container and injected with clean water. The fresh water was changed once in 2-5 days, and the withered and rotten roots were removed at the same time, and water bacon could grow one after another after 1 week.

2. Maintenance guidelines

The main results are as follows: (1) the temperature and light suitable for the growth of Cymbidium is 18-22 ℃, and the temperature below 5 ℃ and above 30 ℃ will inhibit its growth. The gentleman orchid does not have a high demand for light, and it can still blossom without sunshine all the year round. In winter, the room temperature should not be lower than 5 ℃, otherwise the growth will be inhibited, and the plants below 0 ℃ are vulnerable to freezing injury, so pay attention to keep warm.

(2) pay attention to replenish the water consumed in the container on weekdays. When the air is dry and hot in summer, it is often necessary to spray to the leaf surface to increase the relative humidity of the air. Wipe the leaves with a clean wet cloth to keep them fresh and bright [Yoshama Huayao].

(3) the prevention and control of diseases and insect pests is not easy to occur. It is only necessary to pay attention to observe whether there are diseases and insect pests and prevent the occurrence of diseases when selecting water-cultivated plants.

(4) the nutrient solution was added when the water was changed, and the mature plants were sprayed with 0. 1% potassium dihydrogen phosphate diluent to the leaves once when the spring temperature was above 18 ℃ to promote flower bud differentiation. When summer is hot, need to spray water to the leaf surface frequently, or wipe the leaf surface with wet cloth, in order to increase the humidity of the air and leaf surface.

(5) the ornamental effect of Magnolia has phototaxis. When placing the container, the extension direction of the leaf should be parallel to the direction of light entry, and the container should be rotated 180 °every 7-10 days, so that the best ornamental effect of the leaf can be maintained.
