不同大麦品种饲草产量及品质研究

Yield and Quality of Forage Grass of Different Barley Varieties

为了提高饲料大麦的用途,在保山市开展10个大麦品种饲草产量和品质研究,以期筛选出适宜种植的优良大麦饲草品种。结果表明:‘保大麦25号’、‘保大麦20号’、‘保大麦12号’产量表现突出,均比参试品种平均鲜草产量增产,鲜草产量分别为40.15、38.18、38.1 t/hm2;粗蛋白含量较高,分别为10.7%、9.56%、8.69%;粗纤维含量低,分别为24.6%、29.7%、30%;中性洗涤纤维含量较低,分别为48.3%、49.2%、48.8%;酸性洗涤纤维含量较低,分别为25.1%、25.9%、27%;粗脂肪含量较高,分别为9.63%、10.32%、9.86%;无氮浸出物含量高,分别为44.1%、39.2%、41.6%。‘保大麦25号’、‘保大麦20号’、‘保大麦12号’3个大麦品种具有产量高、营养丰富、适口性好、营养价值高的特点,可作为青贮饲料或饲草在保山市适宜区域示范推广,推动畜牧业的发展。

To enhance the use of forage barley,a study about yield and quality of 10 barley forage grass varieties was carried out in Baoshan City,hoping to elect suitable varieties for planting.The results showed that‘Baodamai 25’,‘Baodamai 20’and‘Baodamai 12’had outstanding performance over the average,the fresh grass yield of the three varieties was 40.15,38.18 and 38.1 t/hm2,respectively;the crude protein content was high,which was 10.7%,9.56%and 8.69%,respectively;the crude fiber content was low,which was 24.6%,29.7%and 30%,respectively;the neutral detergent fiber content was low,which was 48.3%,49.2%and48.8%,respectively;the acid detergent fiber content was lower,which was 25.1%,25.9%and 27%,respectively;the crude fat content was relatively high,which was 9.63%,10.32%and 9.86%,respectively;the nitrogen-free extract content was high,which was 44.1%,39.2%and 41.6%,respectively.The three barley varieties,‘Baodamai 25’,‘Baodamai 20’and‘Baodamai 12’,have the characteristics of high yield,rich nutrition,good palatability and high nutritional value,which could be used as silage or forage grass for demonstration and promotion in suitable areas of Baoshan City,thus promoting the development of local animal husbandry.
