摘　　要：高丹草是一种优质新型牧草.目前生产上可选用健宝、晋草1号、泸草1号、苏波丹等品种,在川南以3-5月份播种,每667 m2留苗或移栽16 000～20 000株、刈割后留桩15～20 cm为宜,种植方式则视土质不同而异.The interspecific hybrids between sorghum and Sudan -grass （Sorghum bicolor × S. sedanense） are characteristic of high yield, good adversity -resistance, good quality and palatability. In a field experiment, carried out in Luzhou of China＇s Sichuan province, 4 hybrids were grown with different population density, stump height, sowing date and growing mode. It is recommended that in the environment of southern Sichuan, sorghum -Sudan -grass hybrids be sown in April -May, with a population of 16 000 ～ 20 000 plants/667 m^2 and a 15 ～ 20 cm stump after harvest. The choice of direct sowing and transplanting is decided by the texture of the soil.
