The propagation method of hemp stem flower

You may not know much about this variety, and even many friends have not heard of it. Today, the editor will introduce to you the breeding method of hemp stalk flower. Let's take a look at it together.

I. Propagation methods of hemp stalk flower

Hemp stem flowers are mainly propagated by seeds or ramets. Seed propagation is suitable for sowing in summer and autumn every year, and the seeds mature from June to July and sow immediately after harvest; they germinate about a week later, and when there are 2-3 true leaves, they are transplanted once and can blossom in the following year. Ramet propagation is carried out from post-anthesis to spring shoots, often used as biennial cultivation, and liquid fertilizer can be applied during the growing period.

2. Introduction of planting skills of hemp stem flower

The main results are as follows: 1. In the south, the seeds are sown in the plastic shed in early spring, and the seedlings are moved into the container for about 2 months, and then planted in the pot or out of the nursery.

2. The method of asexual propagation is mainly to cut off the ground plants after autumn flowering, stay in the roots to survive the winter, split the new seedlings in the early spring of the following year, or dig up the old buds before the new seedlings germinate, cut off the roots as propagation materials, and plant 2 or 3 buds per root into the sand bed or nursery ground.

3. Keep it moist regularly and grow into new plants after the spring is warm. Cuttings are often picked from the base when the seedling is about 10 cm high, and the cuttings are inserted into the sand bed or vermiculite bed, and the roots are planted separately.

4. Potted plants need to be dwarfed. The main method is to water less and apply less nitrogen fertilizer to control plant growth. The method of mechanical root injury can also be used. Before the plant grows vigorously and before flowering, the fibrous roots are cut off in situ by stages with a shovel. The growth of the root of the pillar is delayed after being injured, and the goal of early flowering dwarfing can be achieved by repeating it several times.
