Ivy and radish are both chlorophytum plants, and they are shade-tolerant plants, and they can both bask in the sun (but not in direct sunlight, especially in summer, and it doesn't matter if they bask in the sun indoors). As long as it is well ventilated.
Hydroponics of Ivy
Take the ivy out of the flowerpot, soak the clods in water by washing the roots, and carefully remove the soil from the roots. At this time, we should be careful not to waste money and break the roots too much. If the roots are seriously damaged, it is not conducive to future hydroponics.
Root washing also has some disadvantages. For example, it will inevitably wash off the root hairs on the surface of the root system, which is not conducive to the survival of plants. Secondly, the washed roots will still have the color of soil, and hydroponics in transparent containers is not very beautiful.
Therefore, it is best to take root with branches in water for ivy hydroponics, so that the roots produced are not only beautiful in color, but also will not be damaged when washing the roots.
Choose a few twigs, cut them off and put them in a vase. With the temperature in summer, water can grow and take root in a week. Hydroponics often need fresh water. If you want to grow vigorously, you can buy some nutrient solutions for hydroponic plants.
Key points:
1, pick branches with aerial roots.
2. If possible, it is best not to cut the branches first, put a pot or earthen pot next to the big pot of ivy, and put the branches with aerial roots in water or buried in the soil, so there is no risk, even if they can't grow roots, the buds will grow well. Don't cut until the roots are strong.
3. In the process of rooting, do not expose to light, put it in astigmatism or shade, and the temperature should be appropriate, not too hot or too cold. When the roots grow out, they will gradually glow, but some varieties of ivy will not grow well in direct sunlight.
4. After taking root, don't rush from hydroponics to hydroponics, or from hydroponics to hydroponics. Wait until the roots are strong and overgrown, otherwise the new roots will be weak and there may be no way to supply enough growth for the new buds. Changing it immediately may even hurt new roots, so it is difficult to grow back.
5. Choosing all-green varieties is relatively simple. This applies to chlorophytum, ivy and perhaps other green plants. Let's start with the all-green variety! Branches inserted in water are suitable for spring and autumn.
When winter goes and spring comes, first select the semi-lignified branches and vines on the ivy, cut off and remove the basal leaves, and then insert them directly into clean water. Because ivy has the characteristics of long aerial roots, it can quickly adapt to the hydroponic environment when inserted into clear water.
Change the water frequently before inserting water, and it is best to change the fresh water every 1 ~ 2 days to ensure the water body is clean and prevent the lower ends of branches from rotting. About 10 day, young aerial roots grow out. After the new roots grew, Qin Ying also changed the water.
After about 2 ~ 3 weeks, the lovely ivy will show a vigorous growth trend. At this time, the hydroponic flower nutrient solution is added to the water and maintained in a bright place. Don't think that you don't need to change water after adding nutrient solution. In fact, you still need to change the nutrient solution every 2 ~ 3 weeks.
In addition, in the midsummer season, because ivy is in dormancy, clear water should be used instead of cultivation. It is safe to stay indoors in sunny places in winter. As for how to prune or guide the branches and vines according to the needs of modeling and your own preferences, that is a matter of opinion.
Besides dancing with the wind through elegant branches, ivy has many outstanding advantages! First of all, it can absorb the toxic substance benzene, and it can absorb 90% benzene under 24-hour indoor illumination. Secondly, it can also adsorb particulate dust in the air, which is a good helper to purify the air. Thirdly, the stems and leaves of ivy can also be used as medicine, which is bitter in nature, has the effects of expelling wind and promoting diuresis, calming the liver and detoxifying, and can be used to treat joint pain, postpartum cold, headache and other diseases.
cultivation techniques
pot culture
The potted plants of green radish are relatively simple.
There are at least four seedlings in the flowerpot. Potted soil should be loose and fertile, rich in organic matter, which is conducive to molding.
Green radish is required to grow in an environment with high temperature (room temperature should not be lower than 10℃ in winter) and strong scattered light. If it is too dark for a long time, the internodes will be slender and weak, and the leaves will become thinner and lighter, losing luster.
In late spring and early summer (April-August), cut off the branches of 15-30cm, and cut off the leaves of 1-2 nodes at the base.
Pot directly with culture soil, 3-5 plants in each pot, water, plant in a cool and ventilated place, keep the soil moist, and take root and sprout about 1 month, and grow into plants with ornamental value that year.
Maintenance/curing
1, lighting
The original growth condition of green radish is that there is no sunshine in the forest covered by towering trees. However, in the north of autumn and winter, in order to supplement the deficiency of temperature and photosynthesis, the illuminance should be increased.
Method: Put the green radish in the best indoor light, or move to a sealed balcony at noon to bask in the sun. At the same time, when the temperature is low, try to open the window as little as possible, because in a very short time, the leaves may be frostbitten. ?
Indoor cultivation can be placed by the window, but direct sunlight should be avoided. Too strong sunlight will burn the leaves of green radish, and too dark will make the beautiful markings on the leaves disappear. Usually, green radish grows best when it receives scattered light for four hours. Therefore, the green radish can be placed indoors in sunny places all the year round. In the darkroom, it should be moved to the strong light environment for a period of time every half month, otherwise it will easily lead to the growth between rooms and the smaller leaves.
Green radish can be placed near the east or north windowsill in spring, summer and autumn, and can be placed in the south-facing window in winter. If it is placed in a dark environment for a long time, it will not only lead to long white stems, long internodes and scattered plant shapes, but also the yellow and white stripes on the leaves will become smaller and lighter, and even the spots will disappear completely and fade to green.
If cultivated outdoors, attention should be paid to shading, especially in summer to prevent direct sunlight, otherwise the new leaves will become smaller, the color of the leaves will be dim, and the edge of the leaves will be easily burned.
2. 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. Humidity
Refers to the water content of air in the plant growth environment. Under the condition of ensuring normal temperature, increasing humidity is extremely beneficial to plant growth.
There are several ways to raise the temperature.
Keep the plants close to the humidifier, which is turned on for more than 5 hours every day, so that the plants can enjoy the water mist sprayed by the humidifier; Spray water on leaves, stems and aerial roots of plants several times a day with a sprayer adjusted to fog level; Keep a proper amount of water in the flowerpot tray, and improve the local temperature of plants through evaporation of water; Wipe the leaves lightly with a cold wet towel or toilet paper or apply them lightly in a short time (65438+ 0-2 hours a day); Cover plants with transparent plastic film to create the effect of a small greenhouse, and evaporate water vapor in the soil for less than 2 hours every day to replenish water for plants. If the time is too long, it will affect the ventilation and photosynthesis of plants.
4. Water
The watering amount 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. ?
5. Land
In winter, it can grow well under the bright scattered light indoors, with thick stems and bright leaves. In the growing period, there is a high demand for water. In addition to replenishing water to the basin soil normally, it is also necessary to spray water on the blades frequently. For the cultivation of rattan, more water should be sprayed on the palm hair column to make the palm hair fully absorb water for the aerial roots around the stem to absorb. Nitrogen, phosphorus and potassium compound fertilizer can be applied once every two weeks or sprayed with 0.2% potassium dihydrogen phosphate solution every week to make the leaves green and the stripes more vivid.
Green radish likes to be wet, so it is advisable to keep the pot soil moist frequently during the growing season to avoid the pot soil being dry, otherwise it will easily lead to yellowing of leaves and poor plant shape.
If excessive watering causes water accumulation in the basin soil, it is easy to cause rotten roots and dead leaves, especially when the room temperature is low in winter, more attention should be paid to controlling watering. While fully watering in summer, we should also pay attention to spraying water on the leaves frequently. The winter climate is dry, so it is necessary to spray and wash the leaves with warm water every 4-5 days to wash off the dust on the leaves and keep them bright and green.
6, fertilization
Plants grow slowly or even stop growing in autumn and winter in northern China, 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. ?
7. Plastic surgery
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 tops are about 20 cm beyond the brown columns, two or three 40 cm stems and tops are cut off. 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.
Yellow leaf
The green radish bought in winter is usually frozen, and yellow leaves will appear soon after being placed indoors. After these frozen yellow leaves fall, new leaves will be released during the Spring Festival.
Generally, the newly bought radish has an adaptation period of about 1 month in the new environment, and the yellow leaves at the bottom are normal, but remember: yellow leaves or dead leaves should not be peeled directly, but should be cut from the middle of the petiole to avoid excessive water loss and enlarged wounds, which will lead to yellowing of the upper leaves.
Although the green radish is not afraid of darkness, the dark environment will also cause the leaves to turn yellow, and it can be moved to a well-lit place regularly; At the same time, you can't be exposed to the sun Excessive exposure to strong light will not only cause the yellow leaves to fall off, but also lead to the death of the whole plant.
The pot soil is too dry or wet, the metabolism is abnormal, the root system is damaged, and the yellow leaves fall off.
Yellow leaves can also appear due to lack of fertilizer and malnutrition, and fertilizer should be supplemented in time at this time.
Fertilizer can be properly applied with beer. Methods: Beer and water were mixed at the ratio of 1: 1 and sprayed on the stems and leaves.
Too much topdressing can also easily cause root burning, leading to yellowing and withering of leaves. You can dilute the fertilizer with water and let the nutrients go with the water.
