Rohansson, who is believed to be no stranger to all, has an old, green trunk, a long, long life expectancy of up to a hundred years or even a thousand years. Rohanson has extensive land, distribution and cultivation, and can be seen in almost every park and green land. But why is it that rohanson, who is part of the latest edition of the national priority protection directory, is classified as a second-level priority for plant protection

The biology of rohanson
Podocarpus macrophyllus is the common green wood of rohansson, most of which is small, leaves are striped, trepid and secret. Rohanson is a naked plant, male and female. During its four-may term, the male ball was yellow and green, often with three-to-five lumps on very short total lengths; the female ball was often born on herbs alone, in the form of a pious young man. The seed matures from august to september, growing up, red or purple, and the seed ovulation is powdered. Its seeds are connected to the seed, like a monk in a veil. As a result, both female and mature seeds appear to be somewhat similar to the buddhist rohan and are therefore known。

The seeds of rohanson are generally hangable on trees for about a month, and in rain-fed gangnam areas they are often seeded on trees. Once you land, you'll soon be born. Seeds are tenacity and are not easily stored in the long term. The naturally strong rhohansons have age-old phenomena, and sometimes in some cases in other years. Since rohanson is a female and male plant, it is not easy or small in natural conditions, and mature seeds are often preferred by squirrels, birds, etc., with small numbers of seedlings and larvae, an incomplete stock, for reasons closely related to the remains of their own original species. Negative natural factors also pose some threat to the survival of rohanson。

The value of rohanson
Rohansonco plants have survived and are growing since the third century and after the fourth century glaciers, and have gone through a long period of history as one of the important materials for research into ancient botanical science. The lumber of the section's plants is fine-tuned, luminous, dry and easy to process and is of high quality for construction, bridges, shipbuilding, furniture, etc。

Rohan's hymn, yakuza, is unique in form and resistant to trim, is of great value and is conceived as a “long life”, “treasure”, “good fortune”, etc., in harmony with chinese traditional culture and is widely appreciated and cultivated. In gardening, rohanson often cultivates applications in the form of model trees, garden trees, basins, etc. Rohanson branch, which is soft and easy to make, has traditionally been a good material for the production of basin views. Its configuration is mainly made of tungstens, supported by trims and often during hibernation. By cutting, stabbing, pressurizing, bunting, hanging, etc., the maker grows the branches in a particular direction, making them muscular, tilted, cloud-dry, cliff-like and root-type, so as to display his velvet, masculinous atmosphere, obscurity, etc. In the conservation of the basin, as the basin is shallow and solid, water nutrients are consumed, and hot summers require artificial ` fruit' to maintain a certain strength。

In recent years, with the improvement of drug chemistry, pharmacology and chinese drug identification techniques and the development of science and technology, various chemical components have been separated from the rohanson plant, including double-chronone and celery, which are resistant to tumors, oxidation and inflammation. In addition, rohansson contains a variety of acetone-like substances, including visciparol and its congeners, red sagol, and tumour cells such as human colon cancer cells (ht-29), lung cancer cells (a-549), breast cancer cells (mcf7), all of which have some inhibition effect and have high pharmaceutical development value。
In nature, the roots of the rohanson plant are also prevalent. The root tumors have many similarities in form and structure with the root tumors of the legumes, but they are not fully consistent and have nitrogen-fixing functions and great ecological and applied values。
The urgency of protecting rohanson
As people's quality of life gradually improves, the value of rohanson's own vision becomes increasingly popular. According to religious beliefs and superstitions, in the south-west, the absurd saying “home rohanson, i fear not poverty” has been spread, arguing that rohanson can serve as a treasure for the town and serve as a “blacking for money”. As a result of the rejoicing of garden designers and the increased demand for villas, rohanson fans bought their basins, stakes or sculptors from the market at high prices, with the number of transactions rising straight up and prices soaring, with rohanson, over 50 years old, selling more than $100,000 or even millions。
Driven by economic interests, some have gone deep into forest areas and smuggled them for sale at high prices, and reports of poaching and poaching by rohanson are common online. For example, on the coast of guangdong, rohanson, who used to carry the poles, is the most resource-rich, has been “blowed” by the sea winds, and has been scattered over the centuries. The island was the most ecologically primitive place and the natural environment was extremely harsh, but, despite the harsh environment, it had not been able to stop the pace of the poachers, who had been on the island since the 1990s and who were now in a difficult position to trace. In addition to causing serious damage to the rohanson population, the poaching of rohanson has had a very adverse effect on the ecology of the islands, causing the destruction and even disappearance of other local wildlife populations, and may also lead to soil erosion。
Until 2021, as rohanson was not included in the list of priority wildlife protections, law enforcement officials had no legal basis for specific punishments and could only deal with them on the basis of sham legislation. This is extremely detrimental to the effective conservation and rational exploitation of the already endangered and even endangered rohanson species. Surprisingly, rohanson has difficulty recovering even from thieves, with less than 10 per cent. It is gratifying to note that, in the 2021 edition of the national priority protection directory, all rohanson is classified as a national priority for plant protection at the second level, which provides an important legal basis for the protection of rohanson's seed resources。
How to protect rohanson
Rohanson's endangered plant mechanism is based on three main aspects: its own original remnant of endangered properties, overuse of resources, and severe destruction or loss of habitat. Given these aspects, only strict discipline, increased research on cultivation and reproduction, greater awareness and general knowledge of science can serve the purpose of promoting and protecting the environment。
According to flora of china, the chinese plant book (english version), the world has about 100 rohansons, mainly located in the subtropical, tropical and southern temperate zones, mostly in the southern hemisphere. There are seven four variants in the country, spread across the provinces south of the yangtze river and taiwan. The shanghai botanical gardens are maintained in four types, mainly in areas such as pineapple, pyrotechnic gardens, bottage gardens and blue chambers。
Rohanson is warm, wet and semi-climate, colder, less obstinate, more fertile and well drained sandy, and is afraid of flooding and heavy light for long periods of sun. Shanghai is located in the long delta alluvial plains, where the terrain is flat, and the rain season is most prone to plant flooding. Shanghai botanical garden technicians have been active in creating the best conditions for plant survival in order to improve plant growth, creating high and low ground in the park, and digging trenches underground for timely drainage. Rohanson plants that have been collected and preserved since the birth of the shanghai botanical garden (1954), under the care of successive generations of gardeners, remain depressed and arrogant, with flowers growing almost every year. The blue house of the shanghai botanical gardens is the home of a 136-year-old gurohanson, and the podocarpus pilgeri of a hundred years old. In addition, there are 100 yen youths (podocarpus neniforolis) and podocarpus chinensis。
In the broader context of global warming and the process of urbanization, habitat fragmentation has intensified, and the conservation of scarce and endangered wild plant seed resources in china is imperative. The construction of botanical gardens and the continuation of plant seeding practices are essential pathways to shanghai's participation in global national strategies for plant protection and services. In the future, the shanghai botanical garden will continue to build on the entrepreneurship of the older generation of botanical gardeners, strengthen communication and cooperation with national and international counterparts, build on the global biodiversity conservation strategy, sustain basic work on indigenous plant diversity surveys, taxonomy studies, biodiversity inventories and conservation biology, improve quality resource conservation facilities, develop technical standards for plant diversity conservation at different levels, and complete the landing and implementation of the national biodiversity conservation and plant relocation strategy in east china with high quality。
