The Bird's Nest believes that everyone is very familiar. In 2008, it also cooperated with the wisdom of the Chinese people and gave the world a surprise. It has also become one of the symbols of China. So do you know the bird's nest fern? Although there is only one word difference, it is indeed two different forms, one is magnificent and has a lot of value, one is for viewing and is good for the human body. So where is the good thing? What kind of creature is this? Let's take a look at the details about what the nest fern is and how it should be planted.
1. What is the bird's nest fern?
Bird's nest fern is an epiphytic fern native to southeastern Asia, eastern Australia, Indonesia, India, and eastern Africa. It is widely distributed in tropical China. Bird's nest fern, also known as nest fern, Taiwan mountain sago, is iron. A species of the genus Fern, a perennial, genus of herbaceous foliage. Plants 80-100 cm tall, rhizomes erect, short, woody, ca. 2 cm, dark brown, apex densely scaled; scales broadly lanceolate, ca. 1 cm, apex acuminate, entire, membranous Dark brown, slightly shiny.
Second, the distribution of bird's nest fern
Native to Southeast Asia, Eastern Australia, Indonesia, India, and Eastern Africa, it is widely distributed in tropical China.
1. Domestic: China, Taiwan, Guangdong, Guangxi, Hainan (Wuzhishan, Jianfengling), Yunnan (Jinping) and other places;
2. Foreign countries: tropical eastern Africa, Japan (state, four countries, Kyushu, Ryukyu), South Korea (Jeju Island), most of Southeast Asia, tropical regions, Australia and other places.
Third, the nest fern planting and conservation
Bird's nest fern, also known as nest fern, mountain sage, and crown fern, is a genus of the genus Fern, a perennial shaded herbaceous foliage plant. It is native to tropical and subtropical regions and is used internationally to make large hanging or wall-mounted potted plants for hanging in spacious halls. The interior decorated with bird's nest ferns has a unique tropical atmosphere, which adds a bit of vivid white fun. In particular, the bird's nest fern, which has been artificially processed, can broadcast the room to the air, and its leaf-like shape is like the silky shadow of the goddess of flying goddess. The plexiform epiphytic plant is like the bird's nest hanging from the tree end. In recent years, it has become a unique show among the foliage plants, and is deeply loved by people.
1. Botanical characteristics
The bird's nest fern is a medium-sized epiphytic fern. The plant is funnel-shaped or nest-shaped, with a plant height of 60-120 cm. The rhizome is short and erect, the stalk is thick and dense, and the large group of spongy fibrous roots can absorb a lot of water. Leaves clustered, arranged radially on top of rhizomes, hollow as nest-like structure, capable of collecting deciduous and bird droppings; leathery leaves broadly lanceolate, about lOOcm long, 9-15 cm wide in the middle, smooth on both sides, slightly bulging on both sides of veins . The sporangia group is long in strip shape and is born on the upper side of the dorsal vein of the leaf to reach 1/2 of the leaf.
2, growth habits
Bird's nest ferns are often attached to trunks in the rainforest or monsoon forest or to rocks under the forest. The nests of the plexus can carry a large number of litter, bird droppings and rainwater. These substances are converted into humus and can be used as their own nutrients. They can also provide habitat for other tropical epiphytes such as orchids and other tropical epiphytes. condition. Bird's nest fern likes to be hot and humid, and it is not resistant to glare.
Since the bird's nest fern is an epiphytic fern, it is generally not possible to use ordinary culture soil when planting, but use fern root, bark block, moss, crushed brick and wood chips, coconut meal, etc. as a potting substrate. A well-ventilated culture container, and filled with larger granular materials such as broken bricks at the bottom of the container to facilitate ventilation and drainage.
3, cultivation and maintenance points
(1) Planting
The potted bird's nest fern soil can be mainly composed of humus soil or peat soil and vermiculite, and mixed with a small amount of river sand, and a small amount of bone powder and mud is evenly prepared. Pots should be made of porous clay pots or porous plastic baskets. The bottom of the pots should be filled with 1/3 of the broken tiles, and then filled with fern roots, bark, moss, and then the roots of the nest fern In the basin, this growth will be more vigorous. It is necessary to change the basin once every other year.
(2) Temperature and illumination
Bird's nest fern prefers warm, humid and strongly scattered light. It can grow all year round under high temperature and high humidity conditions, and its optimum growth temperature is 22-27 °C. The bird's nest fern should not be exposed to the sun, otherwise the leaf color will become worse and affect the ornamental value.
The spring and autumn seasons can be placed in the shade of outdoor trees for a short period of time. Shade in summer or under the shade of large trees to avoid direct sunlight, which is conducive to growth and leaves. Keep indoors in bright places and not in dark places for a long time. In the winter, it is moved into the greenhouse and the temperature is kept at 16. Above C, it will continue to grow; but it is not cold resistant, and the minimum temperature cannot be lower than 5 °C.
(3) Watering and fertilization
In the spring and summer growth seasons, more water is needed, and water is often sprayed on the leaves to keep the leaves smooth. Generally, the air humidity is preferably maintained at 700% to 80%. When watering, pay attention to the fact that there is no water in the basin, otherwise it will easily lead to death. Under high temperature and high humidity conditions in summer, new leaves need to be sprayed with water, and the leaves are fully sprayed to maintain high air humidity, which is conducive to spore germination and prevent the leaves from drying and curling.
As the blade grows, the blade is often covered with the culture soil in the basin, and the water must be poured through the basin to avoid the dry and curled leaves of the plant due to lack of water. When the room temperature is low in winter, it is better to keep the soil slightly moist. In the growing season, the liquid fertilizer is applied once every 2 weeks to ensure the growth of the plants and the green color of the leaves.
4. Pest control
(1) Anthrax
In the environment of high temperature, high humidity and poor ventilation, the leaves are susceptible to anthrax, the lesions are brown, and the wheel marks are obvious in the later stage. Control method: In the early stage of the disease, 75% chlorothalonil WP 600 times solution, 70% thiophanate-methyl WP 1000 times solution or 10% Shigao water-dispersible granule 2500 times solution can be sprayed evenly every 10 days. Times, 3-4 times in a row. In addition, care should be taken to prevent sunburn, cold damage, etc.
(2) Nematode worms harm the nest fern, which can cause brown reticular spots on the leaves. Control method: It can be applied to the surface of potting soil by using Kedan or Carbofuran particles, and the insecticidal effect is better. In addition, short-term snails and snails should be prevented in time for feeding.
Fourth, the breeding technology of the nest fern
1. Spore reproduction
In the spring, the fine sand and the humus soil are firstly mixed, and after high temperature sterilization, they are put into the seeding pot and flattened, and the mature spores are evenly spread on the potting soil, and then the pot is immersed in the shallow water, and the osmosis is used to make the potting soil full. Moist, moisturize the cover glass, and place it in a cool, cool place. Spores can germinate from 7 days to 10 days. After about 1 month, green protoplasts will grow and grow out after 3 months. When you have a few true leaves, you can cultivate them on the basin.
2, ramets breeding
When the plants grow larger, small branches often appear. The plants that need to be separated can be slowly cut off with a sharp knife before the new shoots are born in late spring and early summer, and then planted separately. Bird's nest ferns produce fewer branches and use less common segregant strains to divide the plants.
The robust plants are usually cut into 2-4 pieces from the base at the end of spring, or the adjacent plantlets are planted and the leaves are cut 1/3-1/2, so that each part has leaves and rhizomes. Then, potted separately into a new plant, covered with a small amount of humus soil; create a humid, ventilated, well-drained environment to heal the wound as soon as possible.
The ambient temperature is controlled at about 25 °C, and the survival rate is high. It should be noted that the potting soil should not be too wet to avoid causing rotten roots. After the new leaves are born, the original shape can be gradually restored. The ramets are the most effective breeding method for flower lovers.
3, tissue culture and rapid propagation
Productive mass reproduction, can use its terminal short stems, young leaves or spores as explants, tissue culture and rapid propagation, can produce a large number of uniform specifications of commercial seedlings in a short time. The spores of Neottopteris nidus were used as raw materials for rapid propagation. The effects of spore treatment, basic medium, hormones and sporophyte induction on culture results were investigated.
The results showed that the spore sacs that had been sterilized and sterilized were cut from the spore leaves, and the spores were broken and inoculated onto 1/2 MS medium. The spores germinated faster and the germination rate was high. The germinated protoplasts were inoculated on MS medium without hormones to obtain a larger proliferation coefficient. It is difficult to induce sporophyte in the test tube in the test tube. It can be induced outside the tube by using 1g/L KH2PO4 solution as an inducer, which is beneficial to the transformation of the original leaf body to the sporophyte.
In vitro studies of spore culture of fast-growing nest ferns. Spore treatment, effects of culture medium, plant hormones and culture-efficient sporophyte induction methods were studied. The results indicate that if the spores are cut from the spore leaves after disinfection, the spores are smashed, inoculated in 1/2 of the MS medium, spore germination and spores or sporangia are directly inoculated at a higher speed and at a faster rate.
The protoplasts have a large reproductive coefficient and are not inoculated with any hormones in the MS medium. It is difficult to induce culture from the sporophytes of the tube body. However, the transformation of the protoplast sporophytes can be induced by spraying 1 g/L of KH2PO4 in a culture pot.
V. Bird's Nest fern hydroponics
1. Bird nest fern hydroponic culture method
(1) Temperature
The growth temperature of the nest fern is 16 ° C -27 ° C, the temperature drops below 10 ° C, the nest fern will grow stagnant, lose the leaf color luster. In winter, it is best to maintain a temperature above 15 °C. If the conditions are not available, keep at least 5 °C, otherwise the edge of the nest will turn brown or even freeze.
(2) Lighting
Bird's nest fern is half-yin, not resistant to strong light, and does not require strong direct light during the growth period, mainly based on scattered light. It is natural light that is injected from a window or the like and naturally scatters indoors. In the summer, try to avoid direct sunlight.
(3) Humidity
Daily water is sprayed on the foliage and surrounding of the nest fern to maintain humidity. You can spray water twice a day. Or wipe the leaves with a towel to increase the humidity and clean the leaves of the nest.
(4) Ventilation
Bird's nest fern can grow well in the air circulation environment. The place where the bird's nest fern is placed in the water should be regularly opened to make the air convect, so that fresh air from outside can enter the room.
(5) nutrient solution
Generally, everyone can use the special nutrient solution for hydroponic culture sold on the market. It should be noted that after the tap water is placed for one day, wait until its temperature is close to room temperature, the chlorine in the water is evaporated, and then the nutrient solution is added in proportion.
(6) Change the water
If tap water is used, it should be placed for one day to allow chlorine to escape and the temperature is moderate. In the summer, generally, about 20 days for the nest fern to change the water, the winter can be longer. If the water quality is clean, the bird's nest fern grows strong and there is no rotten root phenomenon. There is no problem with the time longer, but the amount of water to be evaporated should be replenished in time.
(7) Placement position
Water-fed small plants for bright living rooms, study rooms, and bedrooms.
2, hydroponic matters needing attention
(1) Hydroponic bird's nest fern should choose a single plant with a smaller plant, and adopt the potted root washing method.
(2) Water should be sprayed frequently on the foliage during the growing season to increase the humidity of the air.
(3) Pay attention to the supply of fertilizer. When the fertilizer is too low or the temperature is too low, the leaf edge will turn brown.
(4) Scattered light can be avoided, avoiding sun exposure, so take care to avoid light in summer.
(5) Winter can be over 8°C.
(6) Change the water in about 20 days in summer and longer in winter.
6. Will the nest fern bloom?
In fact, the bird's nest fern does not bloom, because the fern is relatively low compared to the seed plant, and there is no flower structure on the plant, so it does not bloom, mainly depends on spore reproduction, and belongs to the non-flowering plant.
In terms of plant classification, seed plants (nude plants, angiosperms) are relatively high, have a flower structure, and therefore belong to flowering plants, but true flowering plants are a large class of angiosperms, while baths, fungi, moss , ferns, these plants are relatively low, do not have flowers, and therefore belong to non-flowering plants.
Seven, the value of the nest fern
1, ornamental value
The bird's nest fern is a larger type of shaded foliage plant. The bird's nest fern is full-bodied, green and bright, sonic and generous, and has won the favor of people.
