What is the standard answer of Selaginella?

Selaginella is a fern, belonging to Selaginella of Selaginellaceae, and its plants are similar to the branches of cypress. Selaginella roots can leave the soil, curl up like a fist, move with the wind, be proud of meeting water, and dig into the soil to find water. Because of its strong drought tolerance, after a long drought, as long as the roots are soaked in water, they can be elongated again, so it is also called Jiujiuhuan grass.

There is an urgent need for protection methods of Selaginella, orchids and copper grass. There is a leucorrhea in the middle of my orchid leaves. What kind is this?

Selaginella, also known as "Fuxing Grass" and "Evergreen Grass", is a pebbly fern of Selaginellaceae, and its plant height is only about 10cm. Its main stem is upright and stout, and its top is clustered with water branches, which are rosette-shaped, and its branchlets are fan-shaped and forked, which looks like cypress leaves, so it is named Selaginella. During drought, its branches and leaves roll like a bird's head and recover quickly after encountering water. It is green and lovely, green as cypress but better than cypress. Suitable for small potted plants, put it on the desk to enjoy. Selaginella is produced in all parts of China, Japanese and Korean. In nature, it is mostly born in barren hills and dry crevices. Extremely resistant to drought and cold, good at splashing water. If you watch it as a potted plant, you should choose loose and well-drained soil. The propagation of this plant is easy to succeed by seeding with ramets or spores, and the method is the same as that of general ferns. Selaginella has strong vitality, which determines that its cultivation and management can be extensive. When planting, shallow and compact pots should be used. Pot soil can be made of humus and sand, and it should be semi-shaded or sunny every day for maintenance. When watering, you only need to master the dry-wet interval. In its growing season, if organic fertilizer can be applied 1-2 times a month, its growth will be more satisfactory. But after fertilization, wash the leaves with clear water and keep them clean. As long as the temperature drops below 0 degrees in winter for a short time, you can overwinter safely. Selaginella can be used as medicine, which has the function of astringing and stopping bleeding, and can treat proctoptosis, hematemesis, blood collapse and other diseases. Keep some plants at home for a rainy day. Orchids belong to Orchidaceae and are monocotyledonous perennial herbs. Height 20-40 cm, long cylindrical roots. Leaves clustered from stems, linear-lanceolate, slightly leathery, 2-3 in bundles. Orchid is a famous traditional flower in China, which is famous for its fragrance. Orchids have their unique leaves, flowers and fragrance, giving people a very clean and elegant image. 1. Potted soil requirements: loose and well-drained neutral acidic soil with a large amount of humus is the best, and the ph value is generally around 5.5 to 6.5. In Sichuan, Emei fairy soil and "Hong Xing brand" are mostly used to refine orchid plants, and it is more common to cultivate orchids with "bamboo root mud" and humus soil under wet leaf forests in mountainous areas. 2. Location: Orchids can be cultivated outdoors and on balconies in spring, summer and autumn. It is required to choose a place with good ventilation, moist air and no environmental pollution. It's good to be near the pond and the river. At least trees or bamboo forests should be used and sunscreen should be installed to reduce sunlight and temperature. It is best to put the basin on a wooden frame (or steel frame). If the floor is to be bricked, the balcony at home can also be bricked on a small tin can to increase the humidity. 3, proper shading: orchids are mostly semi-shaded plants, and most varieties are afraid of direct sunlight and need proper shading. Orchids can be opened in the first half of April to get more sunshine and promote their growth. In May, in addition to the sunshine at noon, it can also be basked for 6 hours; It has been cloudy all day since June. After 10, except Zhongyang, it can be fully opened for maintenance. Remember this proverb: "leafy shade is good, and more sunshine is good." 4. Rational fertilization: orchids are vegetarian, and fertilization depends on the selected pot soil and growth. Fertilization can be applied to those who grow luxuriantly and have no diseases, and fertilization or a small amount of fertilization is not suitable for those who grow poorly. A new orchid with incomplete roots needs 1-2 years to be fertilized. Generally, in June and July, when the leaf buds of orchids are about 1.5 cm long, the decomposed liquid fertilizer should be applied once every three weeks (the concentration should be around 10%). Don't use chemical fertilizer. If it is not suitable for high temperature season, dilute fertilizer should be applied every two to three weeks from August to September. Orchids should be fertilized at night and watered in the morning, which is called "backwater". 5. Proper watering: Rainwater and spring water are better for orchids, and tap water or rice washing water should be used overnight. When you pour it, pour it from the edge of the basin, not into the bud. The amount of watering should be determined according to the temperature, the degree of dryness and wetness of the basin soil and the growth of bluegrass. Most of the leaves are watered, and the thin leaves are watered less. From April to May, the new buds have not yet been born, so the pot soil should be dry, and the new buds are too wet to rot easily; June-September is the growth period of orchid buds, so it is necessary to increase the amount of watering. Water it once every morning on sunny days, and don't water it in the hot sun at noon. To reduce water consumption in autumn, foliar water spraying can be used to keep the basin soil moist, and water consumption can be controlled to keep "80% dry and 20% wet" in winter. 6. Spraying in the evening: orchids are originally grown in a humid air environment, so in the dry season, in addition to shading, they must be sprayed in the evening to increase the air humidity and lower the temperature; You can also water the orchid floor (desktop), and "one cold and one hot" can stimulate the growth of orchids. 7, wind and rain: "February ghost wind" is a normal phenomenon, you can cut off dead branches and broken leaves. ......
