How to propagate Metasequoia glyptostroboides, list of propagation methods / cutting propagation / sowing propagation

Metasequoia glyptostroboides is a highly ornamental plant, and there are many people who raise it in our country, but with more people raising it, people are more concerned about its reproduction, so how do metasequoia reproduce? What is the reproduction method of metasequoia? Next, the editor will take you to learn about it.

How to reproduce Metasequoia glyptostroboides

On how to reproduce Metasequoia glyptostroboides, in fact, it is mainly divided into two methods: sowing reproduction and cutting propagation. As long as they are operated properly, the survival rates of the two methods are relatively high. As for the specific reproduction methods of these two kinds of metasequoia, how to operate them? It is described in more detail below, so let's take a look at it.

2. List of propagation methods of Metasequoia glyptostroboides (sowing and propagation)

1. Seed harvesting

The fruit of Metasequoia glyptostroboides usually ripens around August every year, and we can harvest it when it is ripe. After harvest, we can wash the seeds and dry them. Then store it and sow it around March of next year.

two。 Seed initiation

Before we sow and propagate Metasequoia glyptostroboides, we must first urge the seeds. We can soak its seeds in warm water for 1-2 days, and when the seeds begin to absorb water and swell, we can take them out and sow them, so that the seeds can germinate faster.

3. Sowing method

Because the seeds of Metasequoia glyptostroboides are small, after sowing, we can use toothpicks to touch the water and stick the seeds into the soil, and then the soil covered with 1cm can be watered. Watering is to pay attention to watering thoroughly, and then the seeds can germinate in about half a month.

3. List of propagation methods of Metasequoia glyptostroboides (cutting propagation)

Cutting propagation is a commonly used method of Metasequoia glyptostroboides. This method has been tested for countless times, and the survival rate is still quite high. The cutting propagation of Metasequoia glyptostroboides is mainly divided into hardwood cuttings and tender wood cuttings, the specific operation methods in the following, we continue to look down.

1. Hardwood cuttage

First of all, we should choose the strong branches from the mother plant that have grown for 2-3 years as cuttings, trim the branches to about 10-15cm, then insert them into the softened soil, and then take root in about 15-20 days. The survival rate of this cutting method is as high as 90%.

two。 Tender wood cuttage

The softwood cuttings of Metasequoia glyptostroboides are usually carried out in May-June, we can choose semi-lignified twigs as cuttings, the best length is about 14-18cm, to retain the upper 4-5 leaves, and then insert 4-6cm on the way, after checking, they should be cultured in a cool place, and then they can be moved to outdoor breeding after a week.

Sowing and propagation of metasequoia glyptostroboides

After the fruit of Metasequoia glyptostroboides is ripe, the seeds are collected and dried, and the seeds are screened out and stored dry after drying. Sowing in March in spring, using strip sowing or sowing in the field, the covering soil should not be too thick after sowing, and always keep the soil moist.

Cuttage propagation of Metasequoia glyptostroboides

Hardwood cuttings and tender wood cuttings can be used.

Metasequoia glyptostroboides hardwood cutting

In January, strong growing branches were cut from 2-3-year-old mother trees as mother cuttings, usually about 15 cm. In early March, the branches were cut in sandy soil to achieve the effect of heat preservation, moisturization and anti-freezing. Soaking in rooting powder solution for 1 day before cutting can promote rooting; all-light seedlings should be adopted after cutting, watering, weeding and loosening soil should be adopted timely.

Softwood cutting of Metasequoia glyptostroboides

The softwood cuttings of Metasequoia glyptostroboides are usually carried out in late May. Select semi-lignified twigs as cuttings, cut into 15cm or so, retain the upper 4 or 5 pinnately compound leaves, and then insert them into the soil. Pay attention to shade after insertion, water can be replenished by spray in summer, while keeping moist, we should also pay attention to ventilation, which can promote cuttings to take root as soon as possible.

Metasequoia glyptostroboides transplant

Metasequoia glyptostroboides can be transplanted from late autumn to early spring, and metasequoia seedlings should be planted immediately to avoid excessive water loss. If long-distance transportation is required, the seedling roots should be immersed in water to replenish water immediately after the plant arrives at its destination. Big seedlings must be transplanted with soil balls, filled with fine soil after applying sufficient basic fertilizer, and watered thoroughly after planting.

Moderate pruning of Metasequoia glyptostroboides

In order to create a ventilated and transparent growth environment for the plant, moderate pruning should be carried out after the forest is grown. It is the best time to prune Metasequoia glyptostroboides after defoliation to the Beginning of Spring, and the pruning intensity is 1 inch, 4 times, 1 stroke, 3, of the total crown length.
