A Detailed Guide to Where to Buy Idesia polycarpa Seeds and How to Grow the Seedlings
Idesia polycarpa, also known as oil grape and water wax gourd, is a deciduous tree in the family Salicaceae (formerly Flacourtiaceae) and the genus Idesia. It is a high-quality, high-yield woody oil tree species with extremely high development value. In addition, the trunk of Idesia polycarpa is straight, and its fruits hang down in clusters like grapes, turning a brilliant red in autumn. It can be used for mountain afforestation and can also serve as a garden landscaping tree species. So where are Idesia polycarpa seeds sold? What are the seedling raising methods? Let's find out together.
Where are Idesia polycarpa seeds sold?
Idesia polycarpa has strong adaptability and strong stress resistance, and is mainly distributed in Hubei, Sichuan, Hunan, Zhejiang, Fujian, Jiangxi, Guangdong, Guizhou and other places south of the Qinling Mountains and the Huaihe River. It can be seen that the production areas of Idesia polycarpa are widely distributed, and the channels for buying seeds are relatively plentiful. In addition to direct sales from production areas, some seedling markets or online e-commerce platforms can also sell Idesia polycarpa seeds; you just need to pay attention to selection techniques.
What are the seedling raising methods?
1. Selection of the seedling raising site
Generally, neutral, slightly acidic or slightly alkaline soil is best, with a soil pH value of 6.8 to 7.2 being suitable, and waterlogging must be avoided. As far as possible, avoid propagating Idesia polycarpa seedlings in nursery production areas for plants such as cypress and crabapple. After the site is selected, soil fertility should also be improved through measures such as intensive cultivation and rational fertilization.
2. Seed treatment
Use screening or hand selection to clean and sort the seeds, remove deteriorated and insect-damaged Idesia polycarpa seeds, and select fresh, plump seeds. Disinfect the seeds before sowing. In addition, the Idesia polycarpa seeds must be treated to promote germination before sowing.
3. Sowing
The suitable sowing time is March to May, and the sowing density is 60 to 160 plants/m2. Given that the field germination rate of sown Idesia polycarpa is relatively low, a sowing rate of 22.5 to 30 kg/hm2 is recommended. Broadcast sowing or drilling is mostly used as the sowing method.
4. Management after sowing
After the seeds germinate, remove the covering in time to prevent the seedlings from growing leggy. Take measures such as shading and cooling to prevent the seedlings from being scorched. Shading can also reduce soil moisture evaporation and maintain soil moisture. Shading is carried out after the covering is removed.
Once the seedlings have emerged completely, loosen the soil and weed. Generally, loosening the soil and weeding are carried out together. Loosen the soil shallowly, keep the surface soil loose, and gradually deepen it each time, but be careful not to damage or crush the seedlings, so as to benefit seedling growth.
Thinning and replanting should be carried out together. When thinning, use your hands or a transplanting trowel to remove overly dense seedlings, diseased and weak seedlings, and poorly growing and abnormal seedlings. Select robust seedlings with intact root systems and replant them in spots where seedlings are sparse or missing.
The above is an introduction to the purchase of Idesia polycarpa seeds and seedling raising methods. In short, raising Idesia polycarpa seedlings from seed is a planting method chosen in many regions. The key is to do a good job in post-sowing management, and at the same time apply fertilizer and irrigate in a timely manner according to plant growth. With proper management, the fruits can set and mature in October to November.
