摘　　要：试验旨在探究不同种植模式对甜高粱产量和品质的影响,为喀什地区甜高粱种植选择适宜的种植模式提供参考。试验分析了一年内甜高粱单作与混作(甜高粱+拉巴豆、甜高粱+青贮玉米)等3种不同种植模式下甜高粱的产量与品质。结果显示:不同种植模式的甜高粱产量、品质差异较大。甜高粱单作的鲜草产量为93.75 t/hm^(2),显著高于其他两种种植模式(P<0.05);甜高粱+青贮玉米混作组干草产量最高,为30.92 t/hm^(2)。甜高粱+拉巴豆混作组的混合饲草的粗蛋白、粗脂肪、总磷含量显著高于另外两组(P<0.05),中性洗涤纤维含量显著低于另外两组(P<0.05)。甜高粱单作组酸性洗涤纤维含量显著高于两种混作模式组(P<0.05)。研究表明,综合鲜干草产量、混合饲草品质,甜高粱+拉巴豆混作饲草品质最好,可作为优质的饲草种植模式选择,为喀什地区豆禾混作饲草提供技术支撑。The purpose of this experiment was to explore the effects of different planting patterns on the yield and quality of sweet sorghum,and to provide reference for selecting suitable planting patterns of sweet sorghum in Kashgar.The yield and quality of sweet sorghum under three different cropping patterns(sweet sorghum+Dolichos lablab,sweet sorghum+silage corn)in one year were analyzed.The results showed that the yield and quality of sweet sorghum in different planting patterns were quite different.The fresh grass yield of sweet sorghum monoculture was 93.75 t/hm^(2),which was significantly higher than the other two planting patterns(P<0.05).The hay yield of sweet sorghum+silage corn mixed cropping group was the highest,which is 30.92 t/hm^(2).The content of crude protein,crude fat and total phosphorus in the mixed forage of sweet sorghum+Dolichos lablab was significantly higher than that of the other two groups(P<0.05),while the content of neutral detergent fiber was significantly lower than that of the other two groups(P<0.05).Acid detergent fiber content of sweet sorghum monoculture group was significantly higher than that of two mixed cropping groups(P<0.05).The study indicates that the quality of sweet sorghum+Dolichos lablab mixed forage grass is the best,which can be used as a high-quality forage planting mode selection and provide technical support for bean-grain mixed forage grass in Kashgar.
