What are the methods for selecting seeds and raising seedlings of Cinnamomum japonicum?
There are all kinds of plants in nature, and surely many people are familiar with Cinnamomum japonicum. It is distributed in many places in our country, and aromatic oil can be extracted from its branches, leaves and bark, so its uses are quite numerous. So how should Cinnamomum japonicum seeds be selected? What are the seedling-raising methods? Next, the editor will explain them to you in detail!
1. How should Cinnamomum japonicum seeds be selected?
When planting Cinnamomum japonicum, seed selection is very important. Good seeds are the prerequisite for improving the germination rate. You should choose plump seeds that are undamaged and disease-free. It is best to use new seeds picked in the same year. Do not buy old seeds, as this will reduce the germination rate. In addition, Cinnamomum japonicum seeds must also undergo sand storage before sowing, which can make the seeds wake up faster and also give a higher survival rate.
2. Seedling-raising methods for Cinnamomum japonicum seeds
1. Seedbed preparation
Choose nutrient soil or materials such as river sand or peat soil as the seedbed soil. You can also buy sterilized culture soil.
2. Selection of cuttings
(1) Cinnamomum japonicum cuttings can be taken in two time periods using different branches. One is in late spring and early autumn, using current-year Cinnamomum japonicum
branchesCinnamomum japonicum branches for softwood cuttings; the other is in early spring, using last year's branches for hardwood cuttings.
(2) When taking softwood cuttings of Cinnamomum japonicum, during the period of vigorous growth from late spring to early autumn, choose current-year vigorously growing branches as cuttings. After cutting the branches off, select the sturdy parts and cut them into sections 5~15 cm long, with each section carrying more than 3 leaf nodes. When cutting the cuttings, note that the upper cut should be made flat about 1 cm above the topmost leaf node, and the lower cut should be made at an angle about 0.5 cm below the bottommost leaf node. Both the upper and lower cuts should be smooth.
(3) When performing hardwood cuttings, after temperatures rise in early spring, choose last year's robust branches as cuttings. Each cutting usually retains 3~4 nodes, and the cutting method is the same as for softwood cuttings.
3. Management after cutting
(1) Temperature: After cutting, ensure that the seedbed humidity is suitable. Excessively high humidity easily causes root and stem rot. When low temperatures occur after cutting, the main measure for keeping warm is to wrap the flowerpot or container used for cutting with plastic film.
(2) Light and humidity: After cutting, use misting to reduce water evaporation from the cuttings. In summer with strong light, shade appropriately, maintain ventilation, and ensure sufficient soil moisture. Pay attention to drainage during the rainy season.
Alright, that is all for the content the editor wants to share with you today. If you want to plant Cinnamomum japonicum, you first need to select high-quality seeds so that the germination rate will increase. In addition, the editor has also shared some seedling-raising methods with you, hoping to help everyone!
