Fern identification: what kind of fern is this? Please give me your advice.

1. The subject in the topic is Dryopteris, not European Pteridopteris. Chinese scientific name PteriscreticaL. Var.nervosa (Thunb.) Ching et S. H. Wu also known as Jinglan grass, leaflet pterygium below 1 picture is the pteridopteris, 2 picture is the European pteridopteris, can be compared.

2. Dryopteris, a variety of European ferns of Pteridaceae, the plant can be up to 1 meter high. The rhizome is long and transverse, densely rusty yellow pilose, and then gradually deciduous. Leaves distant; stalk 20-80 cm long, base 3-6 mm thick, brownish brown or brown straw color, slightly glossy, smooth, with a shallow longitudinal groove above. Leaves subleathery or leathery, dark green, glabrous above, more or less brown or gray-white sparsely hairy or subglabrous on main veins of lobes below.

3. This may be Dryopteris Dryopteris, Dryopteris Dryopteris, Pteris przewalskii, and several different families and genera are similar. It is more reliable to increase the use of spores for microscopic identification. I have specially checked and cultivated the ones you have taken and similar ones. To be honest, people who don't specialize in ferns are more difficult to tell.

4. This is a vegetable fern, the tender stem can be eaten as bracken, and the root can extract fern root powder. Vegetable fern, also known as edible double-cover fern, belongs to the fern family Pteridaceae. Herbs perennial; plants 0.5-5 m tall, rhizomes short and straight. Leaves fascicled; petiole 40-70 cm long; leaves triangular-lanceolate, 50-160 cm long and 30-60 cm wide; primary or bipinnately compound, pinnae lanceolate, 4-6 cm long and 0.6-1 cm wide.

Kidney fern is a medium-sized terrestrial or epiphytic fern with a general height of 30ml / 60cm. Underground with rhizomes, including short and erect stems, creeping stems and spherical tubers. The principal axis of the erect stem extends around to form a stolon, and many tubers are formed from the short branches of the stolon, and the leaflets grow from the tuber to form seedlings.

6. Dryopteris Dryopteris belongs to the genus Dryopteris of the family Pteridaceae, also known as the centipede flag. Is a small stone fern. The height of the plant is 15cm to 35cm. Rhizome short and erect, densely lanceolate scales. Leaves fascicled, petiole short apically articulated, densely hairy and scaly above base to leaf rachis. The leaf is 1-pinnately compound with auriculate processes on the upper side of the pinnae. The sporangia are round, arising from the tip of a veinlet in the forked lateral vein.

How to raise the newly bought Phoenix tail fern

1. Phoenix-tailed ferns do not have a high demand for light. They like to stay in places with bright astigmatism. What they fear most is the exposure of the hot sun, especially the summer sun, which can scorch the leaves of the Phoenix-tailed fern in an afternoon, leaving no vitality at all. The temperature is the most suitable for the growth of Dryopteris Dryopteris, at 10-26 ℃. If the temperature difference between day and night can be maintained at 10 ℃, it is most beneficial to plant growth.

2. Dryopteris should keep the basin soil moist, and there should be sufficient water supply in the growing season. Although it is necessary to keep the soil moist once every 23 days, for Dryopteris, if it is slightly dry during the watering interval, the pteridopteris should not be watered too much, and too much water will lead to leaf shedding temperature management. the suitable temperature for Dryopteris is 16.

3. Fertilization If you want Pterns to grow well, you can apply fertilizer balanced by nitrogen, phosphorus and potassium every half month during the peak season of plant growth, and the concentration must be light. Thin fertilizer and frequent application are most conducive to plant growth. As long as the pteris given a suitable growth temperature for reproduction, the plants will grow longer and fuller, and can be reproduced in different plants. If the temperature is right, plant harvesting can be carried out all year round, as long as you pay attention to shade and moisturize after plant harvesting.

4. Water quality: Pteris grass is suitable for growing in slightly acidic or neutral soft water, and it is difficult for plants to survive in alkaline water. During the maintenance period, it is necessary to provide a suitable water quality environment so that the plants can grow healthily. It is best to adjust the pH value of the water to between 5-0 and the GH value of the water to between 2-12.

5. How to raise Pterosephora after buying When Pteris first bought, we must first provide it with a suitable potted soil environment, preferably sandy soil with good drainage.
