The breeding method and precautions of nest fern

The bird's nest fern, also known as nest fern, mountain perennial fern, crown fern, etc., is a perennial herbaceous foliage plant of the family Pteridaceae. It has high ornamental value and is suspended indoors. It is planted under tropical garden trees or rockery rocks. Potted small plants are used to decorate bright living rooms, conference rooms, study and bedrooms. Let's take a look at the breeding methods and matters needing attention of bird's nest ferns.

Growth habits of bird's nest fern

Bird's nest ferns are distributed in many tropical areas and are attached to tree trunks, rock walls and other places. The base accumulates the fallen leaves of many other tree species and is shaped like a bird's nest, hence the name. The rhizome of the bird's nest fern is short and thick, and the marginal leaves are clustered from the underground stems and are nesting from the central direction. Like high temperature, not resistant to strong light, especially like to attach to the Yulin or seasonal rain forest tree trunks or rocks under the forest.

Breeding methods of bird's nest fern

1. Sowing: first mix the fine sand and humus soil well in spring, disinfect at high temperature, put it into the sowing basin and flatten it, spread the mature spores evenly on the basin soil, then soak the basin soil in shallow water, make the basin soil fully moist, cover the glass to moisturize, and put it in a warm and cool place, the spores can germinate in 7 to 10 days, and the green original leaves will grow after about a month. It can not be cultivated in the pot until a few true leaves grow out after 3 months.

2. Ramet: the ramet propagation of bird's nest fern is generally carried out in the middle and late April. Select the strong growing plant, cut its rhizome together with leaves and root clusters into several pieces, or cut off the small plant, cut off the leaf, put it on the pot, and cover it with a small amount of rotten leaf soil, so as to create a humid, ventilated and well-drained environment. The environmental temperature is controlled at about 25 ℃, and the survival rate is high. Pay attention to the pot soil should not be too wet, so as not to cause rotten roots.

The culture method of bird's nest fern

1. Temperature: whether it is domestic pot cultivation or productive cultivation, it is best to maintain a greenhouse temperature of more than 15 ℃ in winter so that it can continue to grow. when the conditions are not available, it should at least maintain a greenhouse temperature of not less than 5 ℃. If the temperature is too low, the leaf margin will turn brown, and even the plant may die due to cold injury.

2. Lighting: the original environment of bird's nest fern is moist jungle, which is mostly attached to ecology, and can grow normally with a small amount of scattered light, so potted plants can be preserved in bright indoor light all the year round. Such as spring and autumn short-term placed in the shade of outdoor trees or in the greenhouse, it is more conducive to its growth, and can increase the luster of the leaves.

3. Moisture: the bird's nest fern should be fully watered in the growing season, especially in summer, in addition to the cultivation substrate should be often watered, the foliage must be washed 2 to 3 times a day, and the surrounding ground should be sprinkled to humidify, so as to maintain a high air humidity in the local environment, which can not only increase the gloss of the leaf surface, but also is very beneficial to the germination of spore leaves.

4. Soil: the potted substrate of bird's nest fern can be mainly composed of rotten leaf soil, peat soil and vermiculite, mixed with a small amount of river sand, or mixed with fern root, broken bark, moss or broken brick particles and a small amount of humic soil. In addition, a little crushed lime can be added to the basin every spring, which is beneficial to the growth and development of its parasperm.

5. Fertilizer: the bird's nest fern is potted in its vigorous growth season. It is advisable to apply a balanced thin fertilizer of nitrogen, phosphorus and potassium once a month, which can promote it to grow a large number of new leaves. If the plant is short of fertilizer, the leaf edge will turn brown. If the summer temperature is higher than 32 ℃ and the greenhouse temperature is lower than 15 ℃ in winter, all forms of topdressing should be stopped.

Points for attention of bird's nest fern

1. Bird's nest fern is suitable to grow in peat soil or rotten leaf soil, and the suitable temperature for bird's nest fern growth is 22-27 ℃.

2. Under the condition of high temperature and humidity in summer, the growth of new leaves needs more water to maintain the humidity of the air.

3. The breeding of bird's nest fern does not need much sunlight, but only a small amount of scattered light can grow normally.

4. The growing season of bird's nest fern should be fully watered, and the basin soil should be kept moist when the room temperature is low in winter.
