Raising Magnolia in winter to do a good job in five links, prevention and control of diseases and insect pests of edible fungi

In winter, we should make more efforts in 5 links to raise Clivia:

Soil fertilizer: Clivia hi loose fertile neutral or weakly acidic humus soil, cultivation soil can be humus soil 65%, 20% clean sand, fine ash 15% mixed. Clivia winter to apply a solid fertilizer, less nitrogen fertilizer, more phosphorus fertilizer, potassium fertilizer. Eggshell powder and cooked fish fishy water is a good phosphate fertilizer, bran ash, soot is easily available potassium fertilizer. Nitrogen, phosphorus and potassium compound fertilizers can also be applied to promote the germination of more new plants and leaves. Fertilization must be appropriate, do not apply concentrated fertilizer and unfermented fertilizer, otherwise, easy to cause leaf tip withered coke or rot. In winter, if the new leaves appear spots and the roots are yellow, it means that there is too much fertilizer, while the new leaves are narrow, thin and especially light in color, which is the performance of lack of fertilizer.

Watering: The soil should not be too dry or too wet, every watering must be watered thoroughly, and more watering should be done after the bud. Can be every 20 days or so, combined with watering a fermentation of bean cake water, light fishy water and horseshoe water, watering and fertilization combined. When the room temperature is low, control watering to prevent the pot soil from being too wet. If the pot soil is too wet, it will cause the root rot of the plant to die, but it cannot make the pot soil too dry.

Insulation: Clivia growth in winter suitable temperature is 15-20℃, preferably not lower than 10℃. The temperature should be kept at about 18 ° C after the arrow, and the temperature difference between day and night is preferably about 10 ° C, otherwise the flower arrow will bloom if it does not grow to a proper height, and it is easy to form a "clip arrow". When the outdoor temperature is lower than 10℃ at night, clivia should be moved indoors. When the indoor temperature is lower than 10℃, in addition to covering a layer of charcoal powder 1 cm thick on the surface of the pot soil for insulation, the flowerpot should be placed in the indoor sunny warm place. When the indoor temperature is particularly low, the film can be covered on the flowerpot to raise the temperature, but the temperature inside the cover should not exceed 25℃. If it exceeds 25℃, it should be ventilated and cooled in time.

Illumination: Clivia is fond of semi-shade environment, but the longer the sunshine exposure time in winter, the better. When flowering, strong light will shorten the flowering period, and weak light will prolong the flowering period. It likes warm and cool, avoid cold and heat, generally grow well in 18-20℃ temperature, stop growing below 5℃. Clivia into the room, the light was limited, need to manually move the flowerpot to adjust. Under normal circumstances, plant pots should be placed indoors in the sun during the day so that sunlight can reach the plants. Before flowering, the flowerpot should be placed under fluorescent lamp to supplement the light at night. Because the two rows of leaves of Clivia are opposite, if the light is in a position for a long time, it will make the leaves grow irregularly and affect the viewing effect. Therefore, attention should be paid to the direction of the leaves when adjusting the light, and the sunny side should be changed every 10 days or so. There are two ways to swing the flowerpot indoors: one is to parallel the leaves to the sunny window, the other is to perpendicular the leaves to the sunny window, and the latter effect is better than the former.

Prolonged flowering: Clivia flowering mostly from December to March of the following year. The method of prolonging flowering is to place the flowers in a dark place when they are about to bloom, properly control watering, and keep the temperature at 8-12℃. In this way, flowering can be extended by 10-20 days.
