Propagation method of pod fern

Spore propagation and vegetative propagation can be used to reproduce pod fern. These two kinds of breeding methods are commonly used. Let's study them in detail

Spore reproduction

Spore propagation can also be said to be sowing propagation method. The first step is to collect spores. When the spore leaves of pod fern change from dark green to yellowish brown, it means that they can be collected. The time is about the middle and late September. Collect spore leaves from well growing plants. Dry the spore leaves and crush them. Take out the sporangium and put it into the refrigerator at a temperature of about 0 ~ 5 ℃. Before sowing, clean and disinfect with medicinal sterile water, and take out the spores after the sporangium splits

Then there is the production of soil, that is, the matching medium. The selected materials include peat soil, river sand and dark brown soil. In addition, stones and coarse river sand can be sterilized and put into the culture medium. The soil should be moistened before sowing. Then sprinkle the spores on the culture medium, soak them in water, and take them out the next day. Then move the seeded medium indoors. At this time, the indoor temperature should be above 20 ℃ and the humidity should reach the room temperature of more than 80%

Vegetative reproduction

Vegetative reproduction, also known as ramet reproduction, is also a common way of reproduction. This breeding method is usually carried out in spring and autumn. First of all, we should choose the plants with developed rhizomes, good growth and strong growth, and dig out the fern seedlings with roots and soil, so as not to damage the roots. At the same time, dig out the mother body and cut it into several pieces, but ensure that it has roots and leaves to ensure the survival rate. After leveling the soil, carry out cultivation. During cultivation, ensure that the row spacing is 40cm, plant one plant at each acupoint, then cover it with soil, compact it, and then pour water

Precautions for reproduction of podophyllum

It will be difficult to select spore propagation method, so pay attention to the method when selecting spores. The spore sac must be stored in the refrigerator at 0 ~ 5 ℃, washed with sterile water before sowing, and dried on sterile paper before taking out spores. The configured medium should also be sterilized to eliminate the interference of diseases and pests

The selection of vegetative propagation should ensure that the cut mother plant should have roots and leaves, so that it is easy to survive. When planting, do not plant too densely, grasp the spacing, and be sure to compact after covering the soil to ensure full contact between the rhizome and the soil< span>
