红豆草是一种旱中生优良豆科牧草,富含蛋白质、维生素及矿物质,消化率高,素有“牧草皇后”的美称。特别是它的耐旱性、耐贫瘠土壤,以及在风沙危害严重的区域能够正常生长,使其栽培区域广,除北部高寒地区外,华北、西北及东北南部各地都能种植,是治理退化草地(中低山带)首选的优良草种。同时在营养价值、生物量及改良土壤方面与苜蓿相近,而蛋白降解率低于苜蓿,又不产生鼓胀病,青饲安全而优于苜蓿。其开花早,花期长达2~3个月,是优良的蜜源植物。 Soybean is a good middle-aged legume forage grass, rich in protein, vitamins and minerals, high digestibility, known as “forage queen” reputation. In particular, its drought-tolerant and poor-tolerant soils, as well as its ability to grow normally in severely damaged areas of the sandstorms, have made it possible to grow a wide range of cultivated areas. In addition to the northern alpine regions, the areas can be planted in all parts of North China, Northwest China and South-eastern Northeast China. (Low mountain) preferred fine grasses. At the same time, it is similar to alfalfa in nutritional value, biomass and soil improvement, while its protein degradation rate is lower than that of alfalfa without bulging disease. Its early flowering, flowering up to 2 to 3 months, is an excellent honey plant.
