    生物类型: 藤本植物,攀援植物
    葛藤是属于豆科的半木质藤本,具有蔓延性的缠绕茎会形成浓密族群覆盖地面或植物体上。报告指出葛藤已入侵美东地区约2-3百万公顷面积,土地生产力及防除经费每年估计造成50亿美元损失。它居住于温带,或海拔较高的热带地区,几乎所有的生态类型都适合它,从最干的矮丛矮林到永久水体的边缘都可以发现它,但是不长在定期被水淹没的土壤。
    物种描述
    缠绕性木质藤本,10-30公尺长,由地下1-5公尺深,重达数公斤的半木植块根长出。叶互生,三出,小叶约8-18公分长,6-20公分宽,常有浅裂。花红紫色,穗状总状花序。扁平荚果,外被褐毛,开裂散出种子,种子卵形被毛。

    栖息地描述
    The typical natural habitats of kudzu are open lands or shrub lands adjacent to broad-leaved or mixed forests, but it readily invades managed habitats such as road and rail embankments, abandoned pastures, and banks of inland water bodies (EPPO 2007). It colonises a wide variety of natural and semi-natural habitats (EPPO 2007), for example forest edges, disturbed areas or scrub vegetation (van der Maesen 1985 1994 2002; Halim 1992, in Heider et al. 2007). While tropical kudzu (P. phaseoloides) thrives in humid and low altitude habitats, kudzu prefers warm to temperate zones or higher altitudes (van der Maesen 1985 1994 2002; Halim 1992, in Heider et al. 2007). Kudzu thrives in full sun habitats; growth rates and survival are reduced in shaded stands of trees (Abramovitz 1983; Forseth and Teramura 1987, in Forseth and Innis 2004; Carter and Teramura 1988).

    Kudzu grows well with annual precipitation of 1000 to 1500 millimeters on sand or clay soil (Sunet al. 2006). Because of its large roots which act as water reservoirs, kudzu can also withstand fairly dry climates (Shurtleff and Aoyagi 1977, in Mitich 2000; Zhang and Ye 1990, in Sun et al. 2006). It prefers high summer temperatures (over 27°C) and deep, well-drained loamy soils. However the plant is able to survive in frosted and shallow soils even though its roots cannot develop fully (Pron 2006, in EPPO 2007). It is relatively indifferent to soil pH; according to soil analyses the plant can grow in soils with a soil pH from 3 to 8 (EPPO 2007).

    In Japan kudzu ranges in latitude from 44°N to 30°N. It grows abundantly in mountainous areas up to an elevation of 1000 m; it is also found in lowland areas and on many of the small islands. In Korea it grows in areas where the temperature drops to -30°C (Shurtleff and Aoyagi 1977, in Mitich 2000).

    用途
    Kudzu’s greatest potential today may be the powdery extract derived from the plant's roots used as cooking starch. Kudzu leaves, shoots, and flowers are used in salads, soups, sauteed dishes and casseroles. Kudzu has medicinal properties and has been used for millennia in China and Japan to cure a wide range of common ailments (Shurtleff and Aoyagi 1977. In Japan, young kudzu vines are harvested to provide supple waterproof fibers for weaving sturdy wicker baskets or trunks. The cellulose fiber from large vines and roots is used as the basic raw material for making fine traditional paper. The fiber is also used to stuff cushions, beds, and chairs. When burned, it acts as a mosquito repellent (Shurtleff and Aoyagi 1977, in Mitich 2000). Kudzu has been used to produce an unusually fragrant, flavorful honey. Its leguminous roots host nitrogen-fixing bacteria that enrich the soil (Shurtleff and Aoyagi 1977). Kudzu has also been successfully used in the experimental production of methane and gasohol (Hipps 1994, in Mitich 2000). The main uses of kudzu in the United States have been for erosion control and as a forage crop; while kudzu is still valued as a soil-conserving plant for erosion control on steep slopes and embankments, less invasive species are now available for stabilization purposes (Birdsall and Hough-Goldstein 2004).
    Notes
    Climate Change: Jarnevich and Stohlgren (2009) examined how the potential distribution of kudzu will be affected by changing climate and created habitat suitability models that indicate that P. montana may increase its distribution particularly in the Northeast United States with climate change and may decrease in other areas. Predictions of global warming include increases of 3°C to 5°C in mean global temperatures (IPCC 2001, in Forseth and Innis 2004). These trends should favor the spread of P. montana (Forseth and Innis 2004). Kudzu has recently showed northward and westward migration patterns in the United States that correlate with warmer winters and higher CO² levels (Ziska et al. 2009).

    Related Species: P. montana var. lobata is the variety that has been introduced into the United States and South America. The range of this variety overlaps with that of P. montana var. montana in China south of the Yangtze River to Hong Kong. The distribution of P. montana var. montana also includes Vietnam, Burma, Laos and Thailand. In these countries, and in southern China, P. montana var. montana shares its distribution with P. montana var. thomsoni and and P. montana var. chinensis. Specimens from northeast India were identified as P. montana var. thomsoni (van der Maesen 1985, in Britton et al. 2002).

    This profile pertains to Pueraria montana var. lobata. Characteristics that had been used previously to differentiate P. montana from P. lobata and Pueraria thomsoni (Benth.) are lobed leaflets, and the size of wing and keel petals, all of which can be quite variable. For information on the taxonomy of P. montana please see Ward (1998).
