Although the green radish is poisonous, the poisonous part is in the juice. As long as you don't eat the juice of green radish by mistake, it is as harmless as a green leaf plant in the bedroom.
It is better to put no more than two pots of green radish in the bedroom. The light in the bedroom is not very good. As long as the light is turned on at night, the green radish will carry out photosynthesis and respiration at this time. Once there is no light, it can only breathe. Although the carbon dioxide produced by breathing a green radish overnight will not have any effect on the indoor air composition, if there are too many green radish in the bedroom and the light is always not good, then the carbon dioxide content will be more, and people will feel uncomfortable at this time. Therefore, we should pay attention to the fact that there are not too many green carrots in the bedroom, and it is more appropriate to put one or two pots.
Cultivation method of green radish:
1, soil culture and hydroponics
Soil culture: green radish is easy to raise, and the preparation of soil culture is to choose the soil suitable for the growth of green radish. The more fertile the soil, the better. Most of the nutrition of the green radish comes from the soil. Try to choose some soil in the field, mix some animal manure in the soil, and put some fine dead leaves in the soil. Green radish likes soft soil, and dead leaves and feces play a role in increasing soil fertility, softness and ventilation.
Hydroponics: Hydroponics is one of the very good hydroponic plants for indoor decoration, climbing and foliage viewing. Radish stems are thin and soft, and leaves are exquisite and beautiful. Hydroponic radish is extremely shade-tolerant, 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.
2, light and temperature
Illumination: The original growth condition of green radish is in the forest covered by towering trees, and there is no sunshine. However, in the north of autumn and winter, in order to supplement the deficiency of temperature and photosynthesis, the illuminance should be increased.
Temperature: In the north, when the room temperature is above 10℃, the green radish can safely overwinter, and when the room temperature is above 20℃, the green radish can grow normally. It is not a big problem for ordinary families to reach this temperature. It should be noted that the temperature difference is too large, and the leaves should not be close to the heating equipment.
3, water and fertilizer management skills
Watering: The amount of watering in autumn and winter should be strictly controlled according to the room temperature. The temperature before heating is low, and the soil of plants evaporates slowly. Reduce watering, and the water quantity should be controlled between the original 1/4- 1/2. Even after heating, don't pour water too often, and pour less water into the basin. The water should seep through the brown silk. In addition, water should be sprayed on the aerial roots of the palm column to reduce the insufficient water absorption of the roots caused by excessive evaporation. The water poured in winter is better to bask in the sun for a day, and the water is too cold to damage the roots. When raising water, the amount of water should not be too much, and the roots can be submerged. When there is too much water, the stems and leaves are easy to rot.
Fertilization: In northern autumn and winter, plants grow slowly or even stop growing, so fertilization should be reduced. Before winter, liquid inorganic fertilizer is mainly sprayed once every 15 days. Fertilization is mainly sprayed on the leaves after winter, mainly through the stomata on the leaves, and the fertilizer is absorbed through the stomata on the leaves, so the fertilizer effect can directly act on the leaves. Special fertilizer should be used for foliar fertilizer, and ordinary inorganic fertilizer is not easily absorbed by foliar. The flower protection series of Peking University and the flowers produced in Japan can be used as foliar fertilizer.
4. Breeding methods
Usually, the propagation of green radish adopts cutting method. In late spring and early summer, select robust Celastrus orbiculatus, cut off the branches from 1.5cm to 30cm, remove the leaves at the base of 1 to 2 nodes, and be careful not to harm the air roots, then insert them into plain sand or cinder, with the cutting depth of 1/3, and place them in the shade after watering. Spray water on the leaves or cover them with plastic film every day to keep them moist, as long as the environment is not less than 20%.
5. Common diseases
Common diseases of radish: anthracnose, root rot and leaf spot. These three common diseases of radish are harmful to the leaves of plants and affect the ornamental value. Be sure to observe carefully during the maintenance process, and clean and spray chemicals in time if you find that the leaves are sick.
Extended data:
Epipremnum aureum (scientific name: Epipremum aurium) is a large evergreen vine of Araceae, which grows in tropical areas and often climbs rocks and trunks growing in rainforests. Strong entanglement, developed air roots, and can be planted in hydroponics. The petiole on the mature branch is stout, 30-40 cm long, the base is slightly enlarged, the upper node is 2.5-3 cm long, slightly fat, the ventral surface is wide and furrowed, the leaf sheath is long, the leaves are thin and leathery, emerald green, and there are usually many irregular pure yellow patches (especially on the leaf surface), all of which are oval or ovoid, with short and sharp apex, deep heart shape and slightly thick base.
Sorghum impurity adsorption
Green radish can absorb benzene, trichloroethylene, formaldehyde and so on. In the air. According to environmentalists, most of the newly renovated buildings are ventilated, and a few pots of green radish can basically meet the occupancy standards. The newly paved floor is very prone to produce harmful substances. Because green radish can purify benzene, trichloroethylene and formaldehyde in the air at the same time, it is very suitable for being placed in a newly renovated room.
air purification
Green radish also has a strong air purification function and a reputation as a green purifier. In metabolism, radish can convert formaldehyde into substances such as sugar or amino acids, decompose benzene discharged from photocopiers and printers, and absorb it.
Nano-adsorption
The pore size of the pores is between 0.27-0.98 nm, showing crystal arrangement. At the same time, there is weak electricity. The molecular diameters of formaldehyde, ammonia, benzene, toluene and xylene are all between 0.4 and 0.62 nm, and they are all polar molecules, which have the characteristics of preferentially adsorbing harmful gases such as formaldehyde, benzene and TVOC, thus achieving the effect of purifying indoor air.
enjoy
Green radish is an excellent foliage plant with strong winding, developed air roots, bright leaves, evergreen seasons and long drooping branches. It can not only be hung on brown pillars and trunks, but also be placed in halls, hotels, study rooms, windowsills, walls and walls, and can also be used as ground cover plants under the shade of trees. It is a flower suitable for indoor display.
Plant flower language
The flower language of green radish is: tough and kind, watching for happiness.
Green radish lives when it meets water. Because of its tenacious vitality, it is called "flower of life". The spreading green branches and leaves are very easy to satisfy, and even drinking water makes you feel happy.
