How to raise green radish?

How to raise green radish? Green radish belongs to large evergreen vine of Araceae, grows in tropical areas, often climbs and grows on rocks and trunks of rainforest, its entanglement is strong, aerial roots are developed, and can be planted in hydroponic culture. The following small series will introduce how to raise green radish for everyone!

How do green roses reproduce?

Generally, the propagation of green radish adopts cuttage method. In late spring and early summer, healthy green radish vines are selected, branches of 15 cm to 30 cm are cut off, leaves of 1 to 2 nodes at the base are removed, and attention is paid not to hurt the aerial roots. Then, they are inserted into plain sand or cinder, the depth is 1/3 of the cuttings, and enough water is placed in the shade. Water is sprayed on the leaves or covered with plastic film to keep moisture every day. As long as the environment is maintained at not lower than 20℃, the survival rate is above 90%. The specific methods of cuttage method are as follows:

1. Selection and treatment of cuttings: The cuttings should be selected from semi-lignified branches with strong growth and no diseases and insect pests, cut into 10-13 cm long, cut into inclined mouth at the lower incision, leave 2-3 leaves at the upper end, and cut off half of the leaves to reduce water evaporation and facilitate the survival of cuttings.

2, cuttage substrate: cuttage substrate requirements loose breathable, good drainage, high humus loam or sandy soil, it is best to use vermiculite, so rooting fast, high survival rate. Disinfect soil with 2% formalin or 5% potassium permanganate before insertion.

3. Cutting method: dip the prepared cuttings into ABT rooting powder or indolebutyric acid, insert them into the prepared matrix, bury 1/2 of them, irrigate them with water, make the cuttings closely contact with the matrix, and then cover them with plastic film.

4. Post-insertion management

① Pay attention to keeping the soil moist and high air temperature after planting. The soil humidity is about 50%, while the air humidity is 80%-90%.

2. The shade degree of shade shed at the initial stage of cuttage should be kept at about 80%, which can not only prevent direct sunlight from strong light, but also ensure enough scattered light to facilitate photosynthesis of leafy cuttings and rooting.

3. Through the above treatment, roots are basically rooted after 20 days, film can be removed, light can be increased, leaf spray and shade should still be paid attention to in sunny summer, cold protection should be paid in winter, and normal management can be carried out in pots about 10 days after rooting.

How to raise green radish?

1. Light

① The original growth condition of green radish is in the forest covered by towering trees, and the positive is not strong. However, in autumn and winter in the north, in order to supplement the lack of temperature and photosynthesis, it should increase its illumination. You can put the green radish in the best place for indoor lighting, or move it to a sealed balcony at noon to bask in the sun. At the same time, windows should be opened as little as possible when the temperature is low, because the leaves may be frostbitten in a very short time.

Indoor cultivation can be placed next to the window, but to avoid direct sunlight. Too strong sunlight will burn the leaves of green radish, too much shade will make the beautiful stripes disappear on the leaves, usually to receive four hours of scattered light, green radish growth and development best. Therefore, green radish can be placed in the indoor sunny place for four seasons. In the dark indoor light, should be moved every half month to a strong environment to restore a period of time, otherwise easy to make internode growth, leaves become smaller.

Green radish spring, summer, autumn three seasons can be placed in the east or north near the windowsill, winter can be placed in the south window. If it is placed in a dark environment for a long time, it will not only cause the tendril stem to grow longer, the internodes to grow longer, the plant shape to be sparse, but also the yellow and white spots on the leaves will become smaller and lighter, and even the spots will disappear completely and fade into green. Such as outdoor culture, pay attention to shade, especially in summer, pay attention to prevent direct sunlight, otherwise it will lead to small new leaves, dark leaf color, and easy to burn leaf edges.

2, temperature: in the north, room temperature above 10℃, green radish can safely winter, room temperature above 20℃, green radish can grow normally. General family to reach this temperature problem is not big, need to pay attention to is to avoid excessive temperature difference, but also pay attention to leaves do not close to heating equipment.

Humidity: Humidity refers to the moisture content of the air in the plant growth environment. Under normal temperature conditions, increasing humidity is extremely beneficial to plant growth. There are several ways to increase the temperature. Bring the plant close to the humidifier, the humidifier is open for more than 5 hours every day, and the plant can enjoy the mist sprayed by the humidifier; spray water on the leaves, stems and aerial roots of the plant with the sprayer adjusted to the mist scale several times a day; keep a proper amount of water in the flowerpot tray, and increase the local temperature of the plant through its evaporation; wipe the leaf surface lightly with cold wet towel or toilet paper or apply the leaf surface lightly in a short time (1-2 hours a day); The transparent plastic film cover on the plant, creating a small greenhouse effect, through evaporation of moisture in the soil to supplement the water of the plant, no more than 2 hours a day, too long will affect the ventilation and photosynthesis of the plant.

Water: The amount of watering in autumn and winter should be strictly controlled according to room temperature. Before heating, the temperature is low, the soil evaporation of the plant is slow, to reduce watering, the amount of water should be controlled between 1/4-1/2 of the original. Even after heating, watering should not be too frequent, watering should be less poured into the basin, should be brown silk seepage. In addition, water should also be sprayed on the aerial root growth of the palm column to reduce the root water shortage caused by too fast evaporation. Winter irrigation water to dry after a day of water is better, water too cold easy to damage the roots. Water, water can not be too much, submerged roots can, too much water when easy to rot stems and leaves.

5. Soil: In winter, it can grow well under bright scattered light indoors, with strong stem nodes and gorgeous leaves. During the growth period, the requirements for water are relatively high. In addition to the normal replenishment of water to the basin soil, water should be sprayed frequently on the leaves. For column rattan cultivation, more water should be sprayed on the palm hair column to make the palm hair fully absorb water for the aerial root absorption around the stem. Can be applied once every 2 weeks nitrogen phosphorus potassium compound fertilizer or weekly spraying 0.2% potassium dihydrogen phosphate solution, so that leaves green, more vivid stripes. Green dill likes wet, growing season watering to often keep the pot soil wet is appropriate, avoid pot soil dry, otherwise easy to cause yellow leaves and poor plant shape. If too much watering caused basin soil water, but also easy to cause rotten roots, dead leaves, especially in winter when the room temperature is low, more attention should be paid to control watering. Summer in full watering at the same time, but also pay attention to regular spraying on the foliage. Dry winter climate, but also every 4-5 days with warm water spray once the leaves, wash off the dust on the leaves, in order to help keep the leaves bright green.

Fertilization: In the autumn and winter seasons in the north, plants grow slowly or even stop growing, so fertilization should be reduced. Before winter, liquid inorganic fertilizer is mainly sprayed, and the time is about once every 15 days. After winter, the fertilizer is mainly sprayed on the leaves, mainly through the stomata on the leaves, and the fertilizer is absorbed through the stomata on the leaves. The fertilizer efficiency can be directly applied to the leaves. Foliar fertilizer to use special fertilizer, ordinary inorganic fertilizer is not easy to be absorbed by foliage. Peking University flower god series and Japan produced a flower can be used as foliar fertilizer.

7, shaping: each pot planting or direct cuttage 4-5 plants, the middle of the pot set up brown column, easy to green radish winding upward growth. The pruning takes place in spring. When the stem is covered with palm stem and the tip is about 20cm beyond the palm stem, cut off the tip of 2-3 plants by 40cm. When new buds and leaves sprout after cutting, cut off the stem tips of the rest of the plants. For pot plants with whole plants or lower half defoliated due to winter freezing or other reasons, half of the stems and tendrils of the plants can be shortened by 1/2, and the other half of the stems and tendrils can be shortened by 2/3 or 3/4, so that the cutting height is staggered, so that the new leaves growing under the cutting can be quickly covered with brown columns.
