马桑,又名水马桑,属乌桑科马桑属,西南各省海拨400—3200米地区皆有分布。马桑喜光,对土壤要求不严,耐干旱瘠薄,适应性强,是长江中上游、干热河谷地区营造灌木林、乔灌混交林的理想灌木配置树种;马桑萌蘖力强,天然更新快,故在缺林少林,泥沙冲刷严重的山地值得推广。马桑含根瘤菌,有固氮作用,能增加贫瘠土壤的肥力;根系发达,固持土壤,蓄水保肥能力强;茎可提炼栲胶;种子榨油可作油漆和油墨原料,果可提酒精。据测定:马桑叶含氮3.2％、磷1.97％、钾1.4％,
Massang, also known as water Musesang, belongs to the genus Usangke, southwest provinces 400-3200 meters above sea level are all distributed. Ma Sang hi light, lax on the soil, drought-resistant barren, adaptable, is the ideal planting shrubs, shrubs and shrubs to create shrubs, mixed forests of dry and hot valley in the middle and upper reaches of the Yangtze River; Fast, so in the absence of forest Shaolin, sediment erosion serious mountain worth promoting. Maussane contains rhizobia, nitrogen fixation, can increase the fertility of poor soil; root system developed, retaining the soil, strong water retention fertilizer; stems can be extracted gelatin; seed oil can be used as paint and ink raw materials, fruit can mention alcohol . According to the determination: the mulberry leaf nitrogen 3.2%, phosphorus 1.97%, potassium 1.4%
