Big leaf broken bone, also known as Drynaria. Latin name: (Drynaria fortunei), alias many, such as Yajiang, Yanlian ginger, climbing rock ginger, meat broken Bu, stone broken Bu, etc. Pteridoptera, Drynariaceae ferns. It is estimated that many people, like Xiaobian, have never heard of this plant, let alone know how to breed it. In this paper, we sorted out some information about how to breed big leaf bone shreds for your reference.
The culture method of Drynaria macrophylla (also known as Drynaria Drynaria): the best propagation time: the best time for the ramet of Drynaria macrophylla is from May to June;
The best growing soil: sapropel soil with good drainage, slightly acidic soil is the best;
Growth humidity requirements: big leaf bone broken summer high temperature, to maintain a higher air humidity, kidney fern as hanging pot culture, easy to dry, should spray more water, pay attention to ventilation;
The optimum growth temperature is 25 ℃ ~ 30 ℃ because most of them grow in tropical or subtropical regions;
The best growth light: big leaf bone broken like bright scattered light, but also can tolerate low light.
The cultivation method of big leaf osteoclast the matters needing attention in the cultivation of big leaf osteoclast: fertilize once every ten days during the growth period of big leaf osteoclast.
Watering points: Although the big leaf bone is good in warm and humid environment, it should not be watered too much, let alone soaked in water.
Replacement of basin soil: after May of each year, big leaf broken bones can be replaced to loosen the soil, and a small amount of calcium nutrients such as bone powder and eggshell powder can be added, which is more conducive to the growth of kidney fern;
The main points of propagation are as follows: ramets and spores are often used to propagate;
1. Ramets: May to June is better. The mother plant is gently peeled and the stolons are separated. 2-3 clumps of each pot are placed in the shade. When new leaves sprout from the rhizome, it will survive.
2. Spores: Sprinkle the mature spores onto the surface of the rotten leaf soil, spray and moisturize. Sporophytes usually grow after 2 months.
Pest control:
Disease: leaf spot often occurs in summer, and the leaves show dark brown spots, which can be sprayed with 1:1:150 Bordeaux solution or 50% carbendazim 1000 times solution.
Pest: summer is also vulnerable to aphids and red spider damage, can be sprayed with soapy water control.
The effect and function of Daye Gufen are bitter and warm.
① Rihuazi materia medica: "Ping."
② Kaibao materia medica: "bitter, warm, non-toxic." ③ Guangxi Traditional Chinese medicine annals: "sweet and mild, bitter and astringent, warm."
[Guijing] into the liver and kidney channels.
① "Foot Shaoyin."
② Seeking truth from materia medica: "entering the kidney, entering the heart at the same time."
③ "Into the liver and kidney channels."
Functions and indications: tonifying the kidney, promoting blood circulation and stopping bleeding. It is used to treat kidney deficiency, chronic diarrhea, low back pain, rheumatic arthralgia, toothache, tinnitus, contusion, bone injury, appendicitis, alopecia areata and corns.
① According to the research of Zhou tongshui of China Pharmaceutical University, the rhizome water decoction of Dryopteris fortunei (20g / kg, 30g / kg) and naringin were obtained（ Intragastric administration of 20 g / kg (equivalent to the original drug) can promote the healing of experimental bone injury in rats.
② 5-50g / kg by gavage, gushuibu decoction can stimulate compensatory proliferation of osteoarticular chondrocytes in rats with experimental arthritis, and can partially improve the degeneration of articular cartilage caused by the change of mechanical stress line, so as to reduce the incidence of osteoarticular lesions.
③ Drynaria dihydroflavonoid glycosides can increase the beating rate of cultured neonatal rat cardiomyocytes in vitro, make the contraction strong, and have pacing effect on cardiomyocytes. The mechanism of action may be similar to a mechanism β- Receptor agonists.
④ Oral administration of gushuibu Decoction (100%) 0.8ml/kg can significantly prevent the rise of serum cholesterol and triglyceride, and prevent the formation of atherosclerotic plaque of aortic wall in experimental hyperlipidemia rabbits.
⑤ The guinea pig experiment suggested that the combination of Drynaria Decoction and kanamycin could reduce the toxic effect of Kanamycin on cochlea, but could not control the development of toxic deafness after withdrawal of the drug.
⑥ Drynaria decoction can inhibit the growth of Staphylococcus in vitro.
[medicine should be avoided] those with Yin deficiency or without blood stasis should be taken with caution.
① "It's not suitable to use it with fengzao medicine."
② "If there is blood deficiency and wind dryness, blood deficiency and fire, and blood deficiency and contracture, it is forbidden to use it," says Ben Cao Hui Yan
③ "Must match the materia medica": "avoid mutton, blood and Brassica vegetables."
