Culture methods and matters needing attention of Cinnamomum chinense

Red back cinnamon is an evergreen shrub of Euphorbiaceae, which has high ornamental value. Its leaf surface is green, while the leaf back is red, red and green, which is very characteristic.

The culture method of red back cinnamon:

1. Temperature

Red back cassia is a subtropical plant, which is not cold-tolerant. The suitable temperature for growth is between 15-25 ℃, and the overwintering temperature should be not less than 5 ℃.

2. Lighting

Resistant to semi-shade, like scattered light, avoid strong light exposure, summer needs to be placed in a shaded and ventilated place, which is conducive to keeping the red back cinnamon leaf color dark green.

3. Watering

Red back cinnamon likes moist growth environment, but avoid waterlogging. Fully watered during the growing period, keep the basin soil and the surrounding environment moist, but pay attention to avoid stagnant water. Control watering in winter, generally watering every 7-10 days, basin soil is slightly wet and dry.

4. Fertilization

When planting or turning the basin and changing the soil, some compound fertilizer can be applied as the base fertilizer, the compound fertilizer containing nitrogen, phosphorus and potassium can be applied once in the growing period, and 0.2% potassium dihydrogen phosphate solution can be sprayed twice during flowering. Fertilizers are not needed in midsummer and winter.

5. Soil

Like fertile, loose, well-drained sandy loam.

6. Methods of reproduction

Two propagation methods of root division and cuttage can be adopted. The root splitting method is generally carried out in March or April of each year, and 2-3-year-old seedlings are selected for planting. The most common is cuttage propagation, select annual strong branches as cuttings, cut into every three segments into plain soil, about 23 cm deep, shade and moisturizing about two months can take root.

Points for attention of red back cinnamon:

Anthracnose, leaf blight and root-knot nematode disease are common in pest control. The first two diseases can be treated by spraying 65% zinc wettable powder 500 times, and 3% carbofuran granules can be applied to the prevention and control of diseases. Red-backed cassia is easy to be harmed by scale insects, so pay attention to prevention and control.

The cultivation soil must be mixed with acid soil, and the basin should be changed every two years according to the growth situation. It is appropriate to keep it under the shade in the hot season, and applying acid liquid fertilizer every 2-3 weeks can make the branches and leaves luxuriant and keep the leaves bright.

The room temperature in winter should not be lower than 12 ℃, otherwise a large number of leaves will fall and the plants will go into dormancy, and the twigs will wither at the same time. If this happens, re-pruning should be carried out immediately to promote new shoots. Pay attention to the wind when moving out in spring, otherwise it is easy to cause the leaf to curl or even the leaf edge to dry up.

The Cuttage Propagation of Cinnamomum chinense

1. Cutting time of Cinnamomum chinense

Cuttings can be cut in the growing season, and the most appropriate time is before spring buds sprout, when the branches are rich in hormones, accumulate more nutrients, and have a high survival rate after cutting. If you miss the opportunity, you can also cut from late July to mid-August when the spring shoots stop growing and the autumn shoots have not yet germinated.

2. Cutting selection of Cinnamomum chinense.

Select 1-2-year-old strong disease-free branches, leaving the top 2-3 leaves, remove the lower leaves, and cut them into cuttings about 10 cm in length. The lower incision can be soaked in naphthalene acetic acid solution for about 5 minutes before cutting.

3. Cuttage preparation of Cinnamomum chinense

When cutting, choose the place behind the sun and dig an oblong hole, which is about 12 meters long, 1.2 meters wide and 70 centimeters deep. Then dig some dung storage, about 0.4 meters, above can spread a layer of perlite about 20 centimeters. After cutting, it is best to build a plastic Arbor. After the seedbed is finished, the soil is disinfected with potassium manganate solution.

4. Cutting method of Cinnamomum chinense.

First insert a hole with a stick, then insert the cuttings, the depth is 3-4 cm, spray through water, and then cover and seal with plastic film to keep warm and moisturizing.

5. Management after red back and cinnamon insertion

Keep the temperature at about 25 ℃, spray two or three times a day, and ventilate every two or three days. When the cuttings die, you can spray potassium dihydrogen phosphate solution once a week. It can take root in a month or so and can be planted in pots in about 50 days.

In the growing period of red back cassia, it is necessary to keep the basin soil moist, apply light cake liquid fertilizer 1-2 times a month, or use 1% superphosphate water and 0.5% sulfuric acid money water solution to add a small amount of ferrous sulfate, and apply it alternately with liquid fertilizer; in order to keep the basin soil slightly acidic, it is more appropriate to apply some alum fertilizer and water; you can also spray 500-600 times potassium dihydrogen phosphate on the leaf.

In the middle of summer, it should be maintained under the shade shed, once foliar watering in the morning and evening, and I times in 3-4 days; when indoor furnishings are not dry or irrigated, too much water will lead to defoliation and even death. At the end of autumn, red-backed cinnamon should be cultured indoors and keep the indoor temperature above 10 ℃. When the temperature is lower than 5 ℃, the leaves of Cinnamomum chinense will fall off and the freezing injury of twigs will occur. Pay attention to ventilation when maintaining red-backed cinnamon indoors in winter.

Diseases and insect pests are often encountered in the process of red-backed cinnamon culture. Common leaf blight, anthrax harm, choose 50% carbendazim wettable powder 600-800 times liquid or 80% Dysen zinc wettable powder 500-700 times liquid spray control. In addition, there is harm to root-knot nematodes, which can be controlled by 3% Xia Nan Dan granules.

Red back cassia commonly used cutting methods for propagation, cutting is mainly carried out during June to August, can select 1-2 years old strong twigs, cut into 8-10 cm (including 3-4 nodes) long cuttings, retain the first 2 leaves, remove the lower leaves, wait for the cut milk to dry and then insert into the sand bed. Red back cinnamon should be properly shaded, watered at the right time, and maintain a certain air humidity and temperature. Under the condition of 20-25 ℃, red-backed cassia will take root and grow leaves about 30 days after planting.
