China Water (6 photos)

Multi-year biogamous plants, plants 15-30 cm high; root meat, block Slightly 2-3 petals, roots with most binary differences; the leaves are arranged upwards. Leaf juicy, grass, bright green, linear, 15-30 cm long, 1-2 mm wide, 4 longitudinal airway around the center rib, and cross-block separated into a large number of gas chambers, ahead, base, base Hide-shaped, membrane, yellowish white, abdominal is concave, and there is a triangular earlinked leaf tongue, and a spore sac is recessed.

spore cystic, about 9 mm, a diameter of about 3 mm, a white membrane cover; a large spore blast is often caused by a shaft surface of the peripheral blade group, there is a small number of white granular four-sided spores; small spores The sac vesicle is born to the axial surface of the inner blade base, with a majority of gray powder-shaped twoids. Chromosome 2N = 44.

Growing Environment

Mainly growing on the shallow water pool pond and the sludge of the mountain ditch. The distribution area is subtropical, the climate is warm and humid, the spring and summer rain, the winter is cold, the average temperature in January is 2-7 ° C, and the average temperature in July is 27-29 ° C, 1000-1500 mm. Mainly growing on shallow pool, pond and mountain dirt; soil organic matter is rich, pH is 6-6.5. The main accompanying plants include festival, glutinous rice, lotus seeds, water jackets and intestines.

Distribution range

This species is China's unique endangered hydrant ferns. Distributed in Jiangsu (Nanjing), Anhui (宁, 溪 and 当 涂), Zhejiang (Hangzhou, 1653 Zhuji, Jiande and Lishui).

Reproductive method

Trial of the propagation method. When blending, the root plants can be transplanted in a water and humid environment, and the water is given water, avoid excessive drought and water depth, while preventing snails and other pests.

The main value of

The only survival of the water in the water leeks, is classified as a fern, namely small leaf fern, but it is different from Other members such as stone pine, coil, thief, and different from their leaves, there is no integrated leaf vessel. Therefore, there is a certain study value in the system evolution.

Protection level

is included in the "Red Directory of Endangered Species of World Nature Protection" (IUCN) (IUCN) 2004 Ver 3.1 - extreme crisis (CR).

is included in "China Biodiversity Red Directory - Higher Plant Roll" on September 2, 2013 - Endangered.

is included in the "Chinese Species Red Directory" (Plant Section) 2004 - Endangered.

is included in the "National Key Protection Wild Plant" (first batch) August 4, 1999 - I.

is included in the "Chinese Plant Red Book" (Volume 1) September 1991 - Endangered.

population status

Endanger. Distributed in the local area downstream of the Yangtze River basin. Due to the development of farmland production and breeding industry, natural environment changes and waters disappear, which has no longer exist in many places.

Endangered reasons

The survival of China Shui Huaxi residents is facing a threat.

One is that the local farmers have grazed near the group, due to the location of the residence, the water is rich, the water is rich, the water source is sufficient, the horsetable pine forest can cover the sun, the transportation is convenient, it is Well-grazing. The grazing around the group not only has the possibility of budget, but also creates conditions to other species invasion, so that China's water is further reduced.

2 is a large number of five talents invaded, the young five arms are the feed of cattle love, and five treasted herbs, growing More resistant to trample, and most of the time no water is soaked, only the soil holding water is high, and it is very suitable for the growth of the five arms. Therefore, it is very likely to be occupied by five treasures. In addition, there are also river willow growth, China The survival space of the water is getting less and less.

Three is that nearby residents sometimes thrown domestic garbage and dead animals into it, causing water pollution.

four is that there is a poultry farmer owner to engage in poultry farming. Once the farmer owner and the group of land contractors reach the 2113 after the land agreement, it is extremely possible. Become a place to raise poultry.

5 is because most of the residents don't know that China Water is extremely important, here is the urban area, and the human unintentional destruction is increasing, such as stacking Various garbage, construction owners rent land as building materials stacking venues.

Protection measures

It is recommended to have this distributed nature reserve, the landscape protected area should be listed as a protective object, or preserved under cultivation conditions. And reproduce. Hangzhou Botanical Garden has been stored in the aquatic area from the original place.

Protecting the wetland of Zhonghua Huaxi residential group, stopping the hillside and valleys on both sides of the valley as agricultural land and animal husbandry, and in the group Any form of development and utilization activities in the surrounding area, drawing a certain area to establish a protected area, because cultivating, weeding, grazing, application of pesticides, fertilizers and other production and construction of 5261 activities will cause harm and damage to China Water.

Remove its competitive species and leave more survival space to China Water.

The group is surrounded by a wire mesh to prevent illegal collection and livestock and poultry from breaking into the food and trample.

Practicing the dam to prevent leakage to meet the conditions required for Chinese water, and its growth and development.

There are large-scale waterfields around the Shuxun, and a small amount of abandoned farmland. It can consider transplanted some Chinese water leaves to this or will The flow of water flows into these areas to expand the population area and quantity 4102 to increase the genetic diversity of the population.

Protection level

is included in China "National First Level Protection Plant Directory"; included in the "Red Directory of Endangered Species" in World Nature Protection (IUCN " ) - Endangered (EN).
