由美国引进的豆科牧草“美国合萌”，通过９年的研究，知该品种适应性强、耐瘠、耐旱、耐荫、耐湿、耐涝，未见发生严重病虫害，对杂草竞争力好、结瘤力强，种子产量高，种子落地自然更新力强，一年种植可多年利用；适应于年降雨量１０００毫米以上、海拔５００米以下、年均气温１８℃以上的热带亚热带地区种植；在广西全区均可种，并能良好生长。在中等肥力条件下，一般亩产鲜草约４０００千克；在较贫瘠的土壤上鲜草亩产比１８４柱花草、合欢、豇豆、绿豆、胡枝子、大翼豆等都高；植株粗蛋白质含量２０％，总氨基酸达１５７％、赖氨酸０７６％，与禾本科混用可提高动物对纤维素的消化率２１％～４７％。兔子采食后生长发育正常，增重效果显著。７月上旬在大培土后与甘蔗套种，对甘蔗的产量毫无影响，却能每亩收获牧草约８００千克 Introduced by the United States leguminous forage “United States Moe”, through nine years of study, we know that the variety adaptability, resistance to barren, drought, shade, moisture, waterlogging, no serious pests and diseases, competition on weeds Strong, strong nodulation, high seed yield, strong natural renewal of seed landing, year of planting can be used for many years; adapted to annual rainfall of more than 1000 millimeters above sea level, the average annual temperature of 18 ℃ above the tropical subtropical regions Planting; all kinds of species in Guangxi, and good growth. Under moderate fertility conditions, the average yield of fresh grass is about 4000 kg per mu; fresh grass per mu in barren soil is higher than that of 184 columns of flowers such as Acacia, Acacia, Cowpea, Mung Bean, Lespedeza, 20%, total amino acid reached 15.7%, lysine 076%, mixed with grass can increase the animal digestibility of cellulose 21% to 47%. Rabbits after feeding normal growth and weight gain significantly. In early July after large soil and sugar cane intercropping no effect on the production of sugar cane, but can harvest about 800 kg of grass per mu
