The technology of cultivating magnolia

Gentleman orchid with its gentleman-like quality and beautiful flower shape to save the taste of the majority of people like, then for the breeding of gentleman orchid friends, often encounter two problems: that is, how to cultivate gentleman orchid? How to raise magnolia? Below, we will elaborate on the above two issues on the characteristics of the orchid.

Cymbidium is suitable for indoor culture, which is mainly determined by its internal structure and physiological function. Magnolia is an evergreen perennial herb with strong shade tolerance and thick, dark green leaves. Mesophyll contains a lot of chlorophyll, which can absorb carbon dioxide and water in sunlight, synthesize organic matter for its own growth and development, and release oxygen at the same time. In addition, the broad and thick leaves of Cymbidium grow many pores and villi, which can secrete a lot of mucus, and in the process of gas exchange, they can absorb a large amount of dust, dust and harmful gases in the room, making the indoor air clean. Therefore, Cymbidium is also known as "absorption machine" and "dust collector", the protector of human health. So how can this healthy patron saint grow and develop healthily in your home? The family maintenance of Magnolia should mainly start from the aspects of temperature and humidity, soil, moisture, light, nutrition and so on.

As the orchid is native to the mountain forests of South Africa, where the natural environment is like spring all the year round, various parts of the organs of the plant have adapted to this lukewarm natural environment. Therefore, in the daily maintenance process, the temperature should be controlled between 15-25 degrees. When the temperature drops below 10 degrees, the growth and development of Magnolia is slow, when it falls below 0 degrees, it will freeze to death. Similarly, when the temperature reaches or exceeds 30 degrees, it will seriously affect the normal growth and development of Magnolia.

The leaves of Cymbidium are yellowing, which are mostly physiological diseases, and the inducement is some physiological factors, such as temperature, light and water. Ventilation and so on. To prevent the emergence of yellow leaves, we should find out the cause and treat the disease.

(1) temperature: the suitable temperature for the growth of Cymbidium is 1525 ℃. When the summer temperature exceeds 30CC for a long time, the growth is inhibited. At this time, if the air humidity is less than 6Q%, the leaves of Cymbidium will become shallow, yellow and even wilted; if the humidity is higher than 90%, the stems and leaves will grow too much. In order to prevent the occurrence of these bad phenomena, we should reduce the temperature properly, pay attention to ventilation and light transmission, and control humidity. When the temperature dropped below SC, the growth of Cymbidium basically stopped. If the temperature drops to about OC, freezing injury may occur, which will make the leaf tip and leaf edge turn green and yellow, and even appear yellow-white necrotic spots, so we should do a good job of keeping warm in winter to prevent frost injury.

(2) Illumination: Cymbidium is a semi-positive flower, which is fond of scattering light, and too strong light is disadvantageous to its growth and is easy to cause sunburn disease. However, if the light is too dark and lack of light for a long time, the leaves will lose their luster, the old leaves will be dark green, and the new leaves will become thinner, yellow or yellowish green. Some people call this phenomenon of yellow leaves Yin yellow. At this time, the gentleman orchid should be moved to a place with slightly stronger light, and when it is not suitable to move, the light can be used to supplement the illumination.

(3) soil fertilizer: gentleman orchid likes loose and fertile sandy loam, soil consolidation and insufficient supply of fertilizer will make the leaves yellow and affect flowering. At this time, we should increase the application of dilute liquid fertilizer and pay attention to loosening the soil.

(4) moisture: the gentleman orchid likes to be moist, the basin soil is too dry for a long time, and the temperature is high, it is easy to make the leaves yellow. However, too much watering for a long time can easily lead to diseases. Therefore, in the cultivation of Cymbidium, the soil should be kept moist in spring and autumn, slightly dry in dormancy in winter, and the basin soil should not be overheated in summer. the foliage and surrounding ground can be sprayed with fresh water every morning or evening to keep the cool environment.

(5) ventilation: Cymbidium is placed too densely and the surrounding environment is closed, which hinders air circulation and makes the plant thin and yellow. Therefore, it is necessary to strengthen indoor ventilation to avoid crowding.

Water is an important part of Cymbidium. According to the determination, 60% of the moisture in the orchid body is 80% of the moisture, especially its fleshy roots have a strong water storage function and strong resistance to drought. Gentleman orchid likes neutral water, clean and pollution-free tap water, well water, river water and so on can be used for watering, but because the water temperature of fresh tap water and well water is lower than the soil temperature and contains some impurities, it should be placed for 1-2 days before use. As for watering, there is also a lot of fastidiousness. The best way for a gentleman's orchid seedling is to spray it with a sprinkler. Spray the nozzle up to the leaf, which has the advantage of not only watering the flowers, but also washing dust, leaving fog beads on the leaf surface to ensure a certain humidity on the leaf surface, and water evaporation in the sun can reduce the leaf surface temperature and prevent sunburn. But the flowering magnolia can not be watered by sprinkler irrigation to waterproof into the leaf sheath resulting in rotten heart, for the flowering magnolia can only be irrigated into the basin. Then when and how much water is appropriate? This mainly depends on the ambient temperature of the magnolia. The general watering principle is "see wet see dry, do not dry do not water, dry thoroughly". Watering thoroughly is to keep all the roots of the orchid in the same humidity. Judging whether the water is thoroughly watered or not can not be determined only according to whether there is water flowing out from the bottom of the basin. Because sometimes the basin soil hardens and shrinks into a ball after drying, and after watering, water flows quickly from the basin wall to the basin bottom and out from the bottom hole. The central part of the basin soil does not even touch a little water. If you stop watering at this time, it will wilt the leaves of Magnolia and form an arrow when it is running. Here to teach you a simple and effective watering method is to soak all the flowerpots in a basin or bucket filled with water, soak for half a minute and then take them out. But the disadvantage of doing so is that the nutrients in the soil are relatively easy to lose, so if you want to make the magnolia have deep roots and big leaves, you should also pay attention to replenish it in time. The nutritional elements needed by Magnolia mainly come from organic fertilizers, such as bean cake, peanut cruller, animal offal and so on. Under normal circumstances, it can be applied in spring and autumn within a year. In spring, it was applied once in late April and early May after flowering, and again from mid-September to late October after fruit harvest in autumn.
