How to Plant Robinia pseudoacacia
An article about how to plant Robinia pseudoacacia and the maintenance steps related to this green plant, with the following details:
Robinia pseudoacacia, also known as false acacia, is native to North America and belongs to the Fabaceae family, Robinia genus, and is a deciduous tree. Due to its tall and upright appearance, it has certain ornamental value. Additionally, it grows rapidly with a robust and stable trunk, making it suitable for use as construction material. The main propagation method of Robinia pseudoacacia is by seeding. The following is an introduction to the planting method of Robinia pseudoacacia.
1. Seed Treatment
After harvesting the mature pods of Robinia pseudoacacia and drying them in the sun, remove the pod shells and other debris to obtain clean seeds. Before planting, soak the seeds in hot water at 60-80 degrees Celsius, stir for 10 minutes, and then place them in warm water at about 30 degrees Celsius to筛选 out bad seeds and keep the good ones. After selecting the seeds, soak them for another day, then place the swollen seeds on a damp gauze covered with a burlap bag, and wash with warm water. Continue to soak the seeds that have not swollen until they do, repeating the process, and wait for 4-5 days for germination to complete before sowing.
2. Site Selection and Soil Preparation
Choose a high ground with good drainage, fertile neutral or slightly acidic soil, preferably deep loamy soil. Avoid choosing waterlogged or too poor mountainous areas, and do not choose soil that is too heavy and clayey. Moreover, it's best to rotate with trees such as poplar and pine, and require meticulous cultivation.
3. Sowing Process
Sowing can start in May with irrigation. It is better to sow later rather than earlier. Level the seedbed, make furrows for sowing, maintain a certain row spacing, sprinkle the seeds in the furrows, and then cover them with 1-2 centimeters of soil. The seedlings will emerge in about a week.
4. Field Management
1. Water
Robinia pseudoacacia seedlings are drought-resistant but susceptible to flooding. Therefore, do not irrigate before the seedlings emerge. After the seedlings emerge, perform tillage on the soil, and by June, the first irrigation can take place. The frequency in the summer and autumn seasons is 1-2 times per month, stop irrigation in July, and the last irrigation is before winter in November.
2. Fertilization
Also apply the first top dressing at the time of the first irrigation, mainly using nitrogen fertilizer. Maintain a frequency of top dressing twice a month, mainly using compound fertilizers such as nitrogen and phosphate fertilizers. Stop fertilizing by the beginning of August until spring deep tillage when fertilizers dominated by ferrous sulfate can be added to the soil.
3. Cold Prevention
Robinia pseudoacacia is prone to frost damage, so new seedlings should be dug up in the late autumn for afforestation or temporary planting.
4. Loosening Soil and Weeding
After rainfall or tillage, it is necessary to weed the field to prevent weeds from competing with trees for nutrients, which could cause insufficient nutrient supply to the plants.
5. Pest and Disease Control
Seedling blight and aphids are the main pests and diseases that harm Robinia pseudoacacia seedlings. When seedlings are infected with seedling blight, use dinocap spray for treatment; when pest infestations occur, use dimethoate emulsion spray for pest control.
The above is the complete introduction to how to plant Robinia pseudoacacia and the related maintenance steps, for everyone's learning and reference!
