试验证明，红豆草不仅能适应该区气候和土壤条件，而且表现良好，其产草量当年播种，每公顷产鲜草９６００４５ｋｇ，第二年为４６８０２４ｋｇ，第三年为４６４９２３５ｋｇ，第２～３年是当年产草量的５倍；采种宜选择第二年以上地块，两茬每公顷收种２２５０ｋｇ左右，种子大，千粒重２２７２ｇ，幼苗顶土力强，易栽培，翌年４月１０日左右返青，根系强大，侧根分枝多，单株２３条～２５条，重１８ｇ～３２ｇ，根瘤多。在５ｃｍ～２０ｃｍ耕作层内，１ｈｍ２地鲜根重３０６０１５ｋｇ，第二年为１００８０４５ｋｇ，是第一年的３３倍，第三年为２８７７１３５ｋｇ，是第一年的９４倍，是第二年的３倍。
Experiments show that sainfoin can not only adapt to the climate and soil conditions in the area, but also perform well. The yield of seeding grass is 9600.45kg per hectare, 46802.4kg in the second year and 46492.35kg in the third year , 2 to 3 years is 5 times that of the current year; seed selection should choose the second year or more plots, two cropping 2250kg per hectare, seed, grain weight 22 72g, top soil strong seedlings, easy to cultivate April 10 the following year to rejuvenate, a strong root system, lateral root and more branches, 23 to 25 per plant, weighing 18g ~ 32g, nodules and more. In 5cm ~ 20cm farming layer, 1hm2 fresh root weight 3060 15kg, the second year of 10080 45kg, the first year of 3 3 times, the third year of 28771 35kg, is the first year of 9 4 times, is three times the second year.
