通过对凉山光叶紫花苕良种选育及应用研究，系统分析了该草种在不同生态条件下（海拔１５００～３２００ｍ）的生物学和生态学特性。主要经济性状是：分枝期全草干物质中粗蛋白含量为３０．６９％，粗脂肪８．７０％，粗纤维２２．８０％，无氮浸出物为２８．０３％，粗灰分８．７２％，钙１．４８％，磷０．２３％，还含有１７种必需氨基酸。平均鲜草产量４５０００～７５０００ｋｇ／ｈｍ２，种子产量６００～１２００ｋｇ／ｈｍ２。１９９６～１９９８年全州种植面积达８．５万ｈｍ２，鲜草总产２６．２６８亿ｋｇ，产值２．６２６８亿元，推动了全州畜牧业生产的发展。
Through the research on the breeding and application of the fine varieties of Lagerstroemia specious in Liangshan, the biological and ecological characteristics of the grass under different ecological conditions (1500 ~ 3200 m above sea level) were systematically analyzed. The main economic traits are: crude protein content of 30.69%, crude fat of 8.70%, crude fiber of 22.80%, nitrogen-free extract of 28.03% and crude ash content of 8%. 72%, calcium 1.48%, phosphorus 0.23%, also contains 17 kinds of essential amino acids. The average fresh grass yield 45000 ~ 75000kg / hm2, seed yield 600 ~ 1200kg / hm2.1996 ~ 1998 statewide planting area of 85000 hm2, fresh grass production 2.6268 billion kg, the output value of 2.6268 billion yuan, Promote the development of animal husbandry in Quanzhou.
