How to raise green radish
How to raise green radish? Green radish likes warm and humid environment and requires loose, fertile and well-drained soil. Fertile, loose and well-drained humus soil should be selected for potted green radish, and acidic soil is the best. Green radish is extremely resistant to shade and can be placed indoors in sunny places all year round. In a dark room, move to a strong light environment for a period of time every half month, otherwise it will grow easily and the leaves will become smaller. Green radish likes hot and humid environment, the overwintering temperature should not be lower than 15℃, the pot soil should be kept moist, and the leaves should be sprayed with water frequently to improve the air humidity, which is beneficial to the growth of aerial roots. Liquid fertilizer can be poured once a month during the vigorous growth period. For plants that spend a long time indoors, the leaves at the base of their stems are easy to fall off, which reduces the ornamental value. In May and June, when the temperature gets warmer, it can be pruned and updated with cuttings to promote the germination of new buds on the basal stems. ; The specific cultivation method of green radish is as follows:
1. Loose, slightly acidic and neutral sandy loam rich in organic matter is the best cultivation and development place for radish. Change the pot once every three years. Green radish is a negative plant, which avoids direct sunlight, likes scattered light and is more resistant to shade. Usually it takes four hours to receive scattered light, and the growth and development of green radish is the best.
2. Propagation by cutting and burying stems. Choose strong rattan, cut it into two sections, be careful not to hurt the air roots, then insert it into plain sand or cinder to the depth of 1/3 of the cuttings, drench it with water, put it in a cool place, and spray a new high-fat film for moisturizing, and the survival rate will be improved by more than 90%.
Third, the green radish likes greater air humidity and humid environment. Summer is the peak of radish growth, and aerial roots and leaves can be sprayed several times a day, which can not only clean the dust of leaves, but also make leaves green, reduce the temperature of leaves, increase the air humidity in the small environment and make leaves grow better. Fertilization of radish is mainly based on nitrogen fertilizer, supplemented by potassium fertilizer. Spray new high-fat film to keep fertilizer and moisture. In winter, the room temperature is low, and the green radish is in a dormant state. Water less and keep the soil dry.
4. The optimum growth temperature of radish is 20℃-28℃ during the day and 15℃- 18℃ at night. As long as the indoor temperature is not lower than 10℃ in winter, the green radish can survive the winter safely. If the temperature is lower than 5℃, it will easily cause defoliation and affect its growth. Spraying Zhuangganling at the right time during the growth period can make the stems and leaves stout, fresh and tender, and the plants flourish.
Fifth, plastic trimming. 4-5 plants are planted in each pot or directly cutted, and a brown column is set in the middle of the pot to facilitate the winding growth of green radish. Plastic pruning is carried out in spring. When the stems and vines are covered with brown columns and the tips are about 20 cm beyond the brown columns, cut off the stems and tips of 2-3 of them by 40 cm. When new buds and leaves germinate after short cutting, the shoot tips of other plants are cut off. For potted plants whose whole plants or lower leaves fall off due to freezing in winter or other reasons, the stems and vines can be cut by half 1/2, and the other half by 2/3 or 3/4, so that the height of the cuttings is staggered, and the new leaves of rice growing under the cuttings can be quickly covered with brown columns.
What should I do if the leaves of the green radish turn yellow?
Green radish can purify the air, so it will exist in many places such as home, office, shopping mall and restaurant. However, everyone who has raised green radish knows that green radish sometimes has signs of yellow leaves. What is the reason? How to solve it?
1, lack of water, leaves withered. If there is not enough water in the soil, the leaves will turn yellow and fall off. Therefore, green radish should be watered in time.
2, too much water, dark yellow leaves. If there is too much water in the soil or container, the leaves will turn yellow, the leaves will look dull, and even the roots will rot. So stop watering at this time and loosen the soil properly.
3, direct sunlight, leaves wilting. The green radish grows in a cool environment. If it is placed in strong light for a long time, it will easily cause the leaves to wither and turn yellow and fall off. At this time, we should put the green radish in a cool and dark place and water it properly.
4. The light is dim and the new leaves are yellow. If the green radish is left in a dark and unventilated place for a long time, the green leaves will turn yellow due to chlorophyll deficiency, especially the newly grown leaves will turn yellow. At this time, we should put the green radish in a cool and well-lit place.
5, too much fertilization, old leaves fall off. If the green radish is fertilized too much, the overnutrition of the old leaves will accumulate, then turn yellow and finally fall off. At this time, it is necessary to reduce the number of fertilization and water the soil to dilute the fertilizer.
6, insufficient fertilization, roots and leaves turn yellow. Green radish lacks nutrition. When fertilization is insufficient, the color of leaves will gradually fade and turn yellow, especially the leaves at the roots will turn yellow and fall off first. At this time, more fertilization is needed.
7, pay attention to ventilation, the temperature is appropriate. The growth environment of green radish requires ventilation and cool, and the indoor temperature should not be too hot in winter, so attention should be paid to ventilation, otherwise the hot and dry will also cause the green leaves to turn yellow, so it is necessary to open more windows for ventilation and watering to ensure nutrition.
8. Adapt to the environment and pay attention to observation. It usually takes about 30 days for green radish to adapt to the new environment. During this period, some old leaves will show signs of yellowing, which is a normal phenomenon and is in the running-in period. Don't be too anxious to take measures at this time. When it returns to normal, the growth of green radish will flourish.
The role of green radish
Green radish is a large evergreen vine. Growing in tropical areas, climbing on rocks and trunks in rainforests can grow into huge vines. There are yellow spots on the green leaves. Strong entanglement, developed air roots. It can not only be attached to brown columns, placed in lobbies and hotels, but also cultivated to be hung on study rooms and windowsills. It is a flower suitable for indoor display. So what exactly does the green radish do for us? We will discuss them one by one.
First, the decorative effect. Raising such a pot of green radish indoors or outdoors can give people a sense of aesthetic pleasure and make people feel comfortable, so its decorative role is very prominent.
Second, the role of purifying the air. Green radish is a kind of large evergreen vine, which, like chlorophytum and ivy, has strong ability to purify the air. Green radish can absorb benzene, trichloroethylene, formaldehyde and so on. In the air, and suitable for newly renovated new houses to drink. According to environmentalists, a pot of green radish is equivalent to an air purifier in an 8- 10 square meter room. It can be seen that the air purification ability of green radish is still quite strong.
Third, the role of attracting wind. Green radish can attract wind and ventilate the room. Why do you say that? Plants breathe by themselves, absorb carbon dioxide and exhale oxygen. Green radish is usually placed by the window. When the wind is too strong outside, it will block out a little. If there is no wind, it will also release new oxygen. Oxygen enters our living space, which makes us more energetic and the indoor air fresher.
Fourth, the role of absorbing kitchen odor. This is actually an aspect of purifying the air. Putting green radish in the kitchen can effectively absorb some cooking fumes and remove some other kitchen odors. Keep our kitchen fresh.
