Propagation methods of Magnolia mandshurica

There are two main methods for the reproduction of Magnolia magnolia: sowing and grafting.

(1) sowing and raising seedlings

1. The fruit of Magnolia mandshurica matured from September to October, and when it matured, the fruit cracked and exposed the red aril, which should be harvested in time when the fruit was slightly cracked and the aril was just red and yellow. After the fruit is harvested, hang it in the shade for 6 days to promote cracking. Take out the seeds with aril and soak them in clean water for 2 days. Wipe off the aril to remove the shrunken grains, or scrub it with plant ash to remove the aril. The obtained Baijing seeds were mixed with kerosene or zinc phosphide to prevent rodent damage.

2. There are two sowing dates: autumn sowing and spring sowing. The nursery bed should choose fertile and loose sandy soil, turn deeply and kill weeds and insects, and apply sufficient basic fertilizer. After the bed surface is leveled, start sowing ditch, ditch depth 5 cm, width 5 cm, furrow distance about 20 cm, strip sowing, seed evenly sowed in the ditch, slightly compacted after covering the soil.

3. Seeding seedling management can be transplanted when the seedlings have 2 to 3 true leaves. Due to the slow growth in the seedling stage, weeding and loosening the soil should be done frequently. From May to July, applying topdressing for 3 times can use fully mature thin manure water.

(2) raising seedlings by grafting

Magnolia (Magnolia, Magnolia) is commonly used as rootstock for grafting. Magnolia rootstocks are raised by cutting or sowing, and can be used as rootstocks with a dry diameter of about 0.5 cm. From March to April, the sturdy branches with terminal buds of Magnolia magnolia were used as scions. The scions were 5 to 7 cm long and had 1 to 2 axillary buds. The leaves were cut off and grafted at 3 to 5 cm above the ground of the rootstock. After grafting, cultivate the soil and slightly expose the top of the scion to promote the wound healing. The abdominal connection method can also be used, and the interface is about 5 to 10 centimeters from the ground. In some areas, Tianmu Magnolia and Convex Magnolia are used as rootstocks, the grafted seedlings grow faster and the effect is more ideal.
