Spore propagation and vegetative propagation are the ways to reproduce podophylls. These two kinds of breeding methods are common methods. Let's learn more about them.
Spore propagation can also be called seed propagation. The first step is spore collection. When the spore leaves of the pod fern change from dark green to yellowish brown, it means that they can be collected, about the middle and late September. The sporophylls should be collected from the plants with good growth. Dry the sporophylls and grind them up. Take out the sporangia and put them into the refrigerator. The temperature is about 0 ~ 5 ℃. Before sowing, clean and disinfect with sterile water, and take out the spore after the sporangium is cracked.
And then we make the soil, which is to match the culture medium. In addition, we can choose to sterilize the stone and coarse river sand and put them into the culture medium. Before sowing, the soil of the medium should be fully wetted. The medium can be soaked in water to make the soil moist. The spores were then sprinkled on the medium, soaked in water, and removed the next day. Then move the culture medium after sowing to the room, when the temperature in the room should be above 20 ℃, and the humidity should be above 80% of the room temperature.
Vegetative propagation, also known as split propagation, is a common way of propagation. This method of reproduction is usually carried out in spring and autumn. First of all, we should select the plants with well-developed rhizomes and strong growth, dig out the fern seedlings with roots and soil, and do not damage the roots. At the same time, the mother body should be dug out and cut into several pieces, but the root and leaf should be ensured to ensure the survival rate. After the soil is leveled and cultivated, the row spacing shall be 40 cm, and each acupoint shall be planted with one plant, then covered with soil and compacted, and then poured with water.
It will be difficult to select spore propagation method, so pay attention to the method when selecting spores. The sporangia must be stored in a refrigerator at 0 ~ 5 ℃, washed with sterile water before sowing, and dried on sterile paper before taking out spores. The medium should also be sterilized to eliminate the interference of pests.
In order to survive easily, it is necessary to take root and leaves on the mother plant. Do not plant too dense, grasp the spacing, after covering the soil must be compacted, to ensure that the root and soil full contact.
