1、 Sowing and propagation mode

Sowing and reproduction is the most basic way, which can carry out mass reproduction

It is generally necessary to use more than 15 years of Magnolia as the mother plant to collect seeds from it. After collecting the seeds, we need to use a method to preserve the seeds, which is the stratification method. Sowing is generally carried out within the 15th to 30th days of March of the following year

First, the seed trench needs to be dug, and then the seeds are planted into the trench and covered with a layer of soil to fill the excavated trench. Gently compact the soil and don't dig out the seeds. Seeds will germinate slowly after planting. Pay attention to shade, and water and spray frequently. You can apply some fertilizer, but not too much

2、 Grafting propagation mode

Bud grafting is OK, and branch grafting is also OK. Generally, the survival probability of bud grafting is much higher than that of branch grafting. Generally, the grafting time is just before germination in the early spring of each year, or when the shoots mature in autumn

3、 Cutting propagation mode

Generally, from the first ten days of May to the middle of June every year, choose stronger branches on young magnolias. Generally, it is about 10 cm, and two leaves need to be left

Then quickly cut the selected branches from the lower end, dip them slightly in indole butyric acid solution, and then cut them immediately

The seedbed is generally made of clean, sanitary and wet sand. Insert it according to the plant spacing of 15 times 4 cm, and then make the leaves on the branches skew to the other side. Do not overlap or close to the ground

After cutting, you must water it thoroughly, and then cover it with a layer of plastic fresh-keeping film, which must be shaded. Generally, it can be covered with a layer of straw mat. After cuttings survive, weeds must be removed and fertilizer must be applied. Generally, it can be planted after growing for one year. The time of planting can be in late autumn when the leaves fall or in early spring
