摘要
为筛选出适宜贵州地区种植的薏苡（Coix lacryma-jobi）品种（系）,2014～2015年对11个薏苡品种（系）进行田间比较试验,系统测定并分析与动物生产性能相关的粗蛋白、粗纤维、Ca2＋的含量及鲜草产量、干草产量。结果表明：Y81植株高大,茎叶幼嫩,再生能力强,生育期为190～192 d;兴仁小白壳植株矮小,生育期为160 d左右;Y81鲜草产量为86.48～94.21 t/hm2,对照兴仁小白壳为61.23～66.28 t/hm2,Y81比对照增产41.23%～42.14%;Y81干草产量为16.43～17.90 t/hm2,对照为14.08～15.25 t/hm2,增产16.67%～17.42%;Y81茎叶中的粗蛋白含量为14.94%;粗脂肪为4.47%。综合分析,Y81适合作青贮利用,此品种（系）在贵州地区具有推广价值。
In order to select the suitable forage Coix comparisons of 11 forage forage C. lacryma-jobi varieties lacryma -jobi varieties were carried out in for planting in Guizhou, field 2014-2015. The characteristics including crude protein content, crude fiber content, Ca2~ content, fresh yield, dry yield were tested. Results showed that： Y81 had high plant, tender stem and leaves, strong regeneration capacity, and the growth period was between 190 and 192 days. C. lacryma-jobi XingRen had small plant, and the growth period was about 160 days. The fresh grass yield of Y81 was 86.48-94.21 t/hm2, and it 41.23%-42.14% more than C. lacryma-jobi XingRen species which was 61.23-66.28 t/hm2. For dry grass yield, Y81 was 16.43-17.90 t/hm2, 16.67%-17.42% more than the control, which was 14.08-15.25 t/hm2. The crude protein in the stem and leaves of Y81 was 14.94%, while that of the control was 4.47%. Y81 was suitable for forage cultivation and worthy of promotion.
