Transverse length of Lagerstroemia indica branches

The most common propagation methods of Osmunda japonica are sowing propagation, cutting propagation and layering propagation, among which cutting propagation and sowing propagation are the most commonly used. Generally, it is more appropriate to choose March every spring. At this time, plants grow vigorously, the climate is suitable, and the survival rate of reproduction is high.

The most common propagation methods of Osmunda japonica are sowing propagation, cutting propagation and layering propagation, among which cutting propagation and sowing propagation are more commonly used, and it is generally more suitable to choose to breed in March every spring.

1, cutting propagation

(1) Time: Osmunda japonica is usually propagated by cutting, and March is more suitable every spring. At this time, plants grow vigorously, the climate is suitable, and the survival rate of reproduction is high.

(2) Method: Select some robust branches of Osmunda japonica, preferably those that have grown for more than one year, and the length of branches is about 10 ~ 15cm, leaving only 3~4 leaves. Before cutting, you can soak carbendazim and rooting powder in water and then cut in suitable soil.

2, sowing and breeding

(1) Time: Osmunda japonica seeds are collected in winter from 1 1 2 every year, and then sown in sand from February to March in the following spring.

(2) Method: Before sowing, mature seeds need to germinate, and the seeds are soaked in warm water at 40℃ for a period of time. Sowing requires high-temperature disinfection of the soil, and then sowing on demand.
