When is the best time to plant toona sinensis seeds
Living knowledge series, regarding the best time to plant toona sinensis seeds and the green plant maintenance tips for planting time and methods of toona sinensis seeds, here is a detailed introduction.
Toona sinensis trees are more commonly found in rural areas, with some being wild. Fresh toona sinensis sprouts are a type of delicacy pursued by people, and toona sinensis trees have become a widely planted economic species. The germination temperature of toona sinensis trees is between 5-10 degrees Celsius. Transplanting before germination, reasonable water and fertilizer management, seedlings germinate quickly and recover from transplant shock rapidly. Toona sinensis roots are relatively shallow, so planting should not be too deep to avoid root suffocation. Controlling planting density and depth can improve survival rates. Toona sinensis trees may experience diseases and pests during growth, with the growing period being the high-incidence period. Preventive cleaning and control measures should be taken, with common diseases being prevented in advance. Immediate action should be taken with chemical sprays or cleaning and garden management upon discovering diseases or pests, as well as strengthening fertilization to improve resistance to diseases and pests.
1. Planting Time
Toona sinensis trees are suitable for planting in spring when the temperature exceeds 5°C. In the southern regions, planting can start in early March, while in the northern regions, it should be postponed appropriately.
2. Seed Selection
Choose good-quality varieties according to your own situation, focusing on selecting seeds that are large, plump, fresh, free of pests, and intact, as these seeds have a higher germination rate.
3. Seed Soaking and Germination
Gently rub the toona sinensis seeds first, then wash and soak the seeds in warm water, drain the seeds, and place them in a clean container to germinate at a temperature of 25-30°C. The seeds can germinate in about 2-3 days.
4. Sowing Seeds
When most of the toona sinensis seeds show white tips, they can be sown. Use the spot sowing method, with the surface soil not too deep. After sowing, water the seeds. After the toona sinensis seedlings emerge, strengthen management, keep the soil slightly moist, appropriately increase sunlight, and apply dilute nitrogen fertilizer to promote the growth of seedlings.
5. Transplanting and Planting
When the toona sinensis seedlings reach a certain size, they can be transplanted into the field, given sufficient sunlight and reasonable water and fertilizer to accelerate growth.
6. Watering Method
When the new shoots are 3 cm long, spray 0.25% urea to supplement nutrients and promote the growth of young branches and leaves. Water regularly in spring, frequently in summer, and perform tillage and weeding. Determine the watering frequency based on local irrigation conditions and climatic characteristics to promote vigorous plant growth.
7. Fertilization Method
Toona sinensis trees are easy to manage, and additional fertilization during the maintenance period can make the seedlings grow faster and the plant shape more full and tall. Toona sinensis tree planting mainly uses potassium fertilizer, with regular top dressing to promote branching. Solid or liquid fertilizers can be used, with liquid fertilizers having stronger absorption and a quicker effect.
8. Powdery Mildew Control Method
Powdery mildew is common in toona sinensis trees, with yellow and white spots appearing on the leaves during outbreaks. First, clean up the affected leaves and branches, improve ventilation, spray chemicals to control the disease, and strengthen pruning and wound treatment to reduce disease threats.
9. Control Method for Dry Rot Disease
Dry rot disease has a higher incidence in young trees, mainly affecting branches and trunks, where small black spots appear. First, control the spread of the disease, cut off the affected branches, and disinfect the wounds to prevent infection. Then spray the medicine to kill the bacteria lurking on the tree trunks.
10. Control Method for Leaf Rust Disease
The main manifestation of leaf rust disease is the appearance of rust spots on the leaves, early leaf drop, weak growth, and small black spots on the leaf back. Detect and prevent the disease early in the outbreak to quickly control the situation. You can spray a 1-3 degree Bordeaux mixture, applying 2-3 times with a one-week interval between each application.
The above is a complete introduction to when to plant toona sinensis seeds and the planting time and methods of toona sinensis seeds, for everyone to learn and understand!
