Photinia frondosa is recorded in the family Rosaceae. The plant is aliased as flame red, millennium red, heather, etc. It belongs to garden ornamental plants and belongs to the genus. This article is to introduce to you today, the cutting technique of Photinia frondosa, and precautions.
[Red leaf heather cutting technology]
Photinia frondosa, an evergreen shrub species with a plant height range of 1-2 m, is suitable for planting in gardens and gardens.
Cutting into the greenhouse. The breeding of Photinia frondosa seedlings is recommended to be carried out in greenhouses. Monolithic cuttings can be used to directly cover the outer membrane on the outer layer, and a layer of shading net can be placed on the skeleton.
seedbed. The seedbed of Photinia frondosa should be chosen to be acidic, and the location of the seedbed should have good irrigation and drainage. After the soil is completed, the amount of fertilizer can be applied, and the calcium phosphate can be selected. Before the cutting, the ditch can be drained.
The cutting time of Photinia frondosa, the choice of cuttings for its breeding method, has the advantages of low cost, simple method, high survival rate, and has no restrictions on cutting technology and cutting location.
The best cutting time of the plant is spring, about the beginning of March, and secondly, in June and September, the cutting can be carried out, mainly based on the regional climate.
When cutting the spring cutting, you should collect the cuttings in the autumn of the first year, and choose the 1-3 year old shoots, then cut them about 15 centimeters and bury them directly with soil.
When cutting, remove the cuttings and soak them in clean water. After about two days, you can cut them directly. The shoots on the cuttings should be wiped off directly, then cut directly upwards according to the direction of the buds, and the depth of the soil inserted into the soil is about two-thirds, and one-third of them can be left.
[Notes on the insertion of red leaf heather]
Note on seedling bed After the cutting, the water content of the soil of the seedling bed should be checked once a day, about 60%. After about half a month, the water content can be gradually reduced to about 40%.
The first week after the cutting of Photinia frondosa is a rooting period. At this time, fertilization should not be applied, and the main nutrient is clear water. Therefore, the seedbed should not face water shortage, and water accumulation cannot occur.
The main reason for choosing the shed in the shed is because of better control of temperature and humidity. After the cutting is completed, the humidity in the shed should be controlled above 95%, and the temperature is up to 38 degrees Celsius and the lowest is 20 degrees Celsius.
Once the temperature in the shed rises, in addition to the shading net work, you can also choose to use a sprayer to cool down. After a week of cutting, avoid direct sunlight. After about 15 days of growth, you can avoid the hot sun according to the sunshine time and pass the astigmatism. The sunshade net is properly opened, and the overall light transmittance of the greenhouse is about 50%.
Summary: The cuttings of Photinia frondosa are mainly based on greenhouse conservation. Therefore, the management after cuttings only needs to be properly watered and fertilized according to the growth needs of the plants.
