How to propagate Prunus triloba
Today, the editor will explain how to propagate Prunus triloba and the knowledge of Prunus triloba cutting propagation and flower breeding techniques. The following is an introduction for you.
Prunus triloba is a plant with high ornamental value, and many people are raising it now. Do you know how to propagate Prunus triloba and how to manage it after cutting? Today, I will introduce the propagation methods of Prunus triloba.
I. Propagation methods of Prunus triloba
Propagation can be done by播种 (seeding) and grafting.
Seeding is divided into autumn sowing and spring sowing.
Autumn sowing: In the late November, prepare the land with a row spacing of 60 centimeters, dig trenches not too deep to ensure the seeds are placed in the sowing rows as required. After digging the trenches, the seeds are sown and covered with soil made by livestock, then pressed. The seedlings will emerge in the fourth month of the following year.
Spring sowing: In February of the same year, the seeds are stored in sand and sown in the ground in late March, the same as autumn sowing.
Autumn sowing allows earlier seedling emergence, which can extend the growth period and improve seedling quality.
Double petal Prunus triloba needs to be obtained through grafting, using methods such as branch grafting or bud grafting, with mountain peach or single-petal Prunus triloba as the rootstock. Branch grafting can be done by cut grafting or abdominal grafting. In the climate of Beijing, the best time for branch grafting is late March, and it should not be later than early April.
Bud grafting is most suitable in August, using the one-point-one-horizontal grafting method, with an efficiency of over 1000 plants per worker and a survival rate of over 90%. Prunus triloba can also be grown as a potted plant.
II. Cultivation methods of Prunus triloba
1. Soil: Not strict requirements for soil, but not tolerant to waterlogging, prefers neutral to slightly alkaline, fertile, and loose sandy loam soil.
2. Watering: Avoid waterlogging, water 2-3 times in spring planting if the weather is dry, otherwise no need to water, and pay attention to drainage during the rainy season.
3. Sunlight: In autumn, winter, and spring, it can be exposed to plenty of sunlight. When kept indoors, try to place it in a bright place, such as a well-lit living room, bedroom, study, etc.
4. Temperature: Likes warm climates, but high summer temperatures and humid environments are not conducive to its growth; strict requirements for winter temperatures, growth stops at temperatures below 10°C, and cannot survive in frost.
5. Pests and diseases: The main diseases and pests of Prunus triloba include brown spot disease, white stripe disease, aphids, caterpillars, red spiders, and leaf-rolling moths, which usually occur in summer and autumn, and should be promptly treated with pesticides.
III. Management after cutting Prunus triloba
Temperature: Prunus triloba cuttings are most likely to root in an environment of 20-30°C. The higher the temperature, the greater the possibility of root rot; too low temperature makes it difficult for cuttings to root. If encounter low temperature after cutting, measures for insulation are important, such as wrapping the pot with plastic film; if the temperature is too high, shading is required, and the cuttings and their surroundings should be sprayed 3-5 times a day.
Humidity: After cutting Prunus triloba, it is necessary to maintain a relative humidity of 75-85% in the air. Since the cuttings cannot absorb water before roots develop, it is necessary to spray frequently to reduce water evaporation and grow in a shaded environment. The frequency of spraying is about 3-5 times a day, and it should be adjusted appropriately on sunny and rainy days.
Light: Cutting propagation cannot do without sunlight, as the cuttings still need to photosynthesize to produce nutrients and substances for root growth. However, the stronger the light, the more obvious the transpiration, the faster the water loss, which is not conducive to the survival of the cuttings. Therefore, after cutting, it is necessary to shade appropriately to ensure photosynthesis and retain moisture. After the roots grow, transplantation can be carried out.
The above information about how to cut Prunus triloba and the techniques for Prunus triloba cutting propagation can be used as a reference for green plant enthusiasts.
