为了研究6种不同来源草木樨的生产性能与营养品质差异,试验选出适宜于新疆栽种的品种,采用大田测定及实验室测定方法,测定了不同来源草木樨生物特性、产量及营养成分,并通过计算粗饲料分级指数(GI值)对营养品质进行了综合评定。结果表明:MAL001(来自甘肃的白花草木樨)的全年干草产量最高,为11 500 kg/hm2,MOF001(来自甘肃的黄花草木樨)粗蛋白产量最高,为1 729.18 kg/hm2。6种草木樨全年干草产量高低顺序为MAL001(来自甘肃的白花草木樨)、MAL002(来自内蒙古的白花草木樨)、MOF003(来自宁夏的黄花草木樨)、MOF001(来自甘肃的黄花草木樨)、MOF002(来自吉林的黄花草木樨)、MIN001(来自江苏的印度草木樨),全年粗蛋白产量高低顺序为MOF001>MAL001>MAL002>MOF003>MOF002>MIN001。通过GI指数对6种草木樨的营养品质进行综合比较,营养价值高低为MOF002>MIN001>MAL001>MOF001>MAL002>MOF003。根据综合营养品质和生产性能进行评定,MAL001最适宜在阿拉尔市栽培,其次为MAL002。
In order to study the difference of production performance and nutritional quality among six different sources of herbaceous shrews, the varieties suitable for planting in Xinjiang were selected and tested. The biological characteristics, yield and nutritional components of different origins of shrubs were determined by field and laboratory methods A comprehensive assessment of nutritional quality was made by calculating the forage grading index (GI). The results showed that the highest annual hay yield was 11 500 kg / hm2 for MAL001 (Grifola fruticosa) from Gansu, and the highest crude protein yield for MOF001 (Houttuynia cordata from Gansu) was 1 729.18 kg / hm2 The order of the hay production for the whole year was MAL001 (white flowers from Gansu), MAL002 (white flowers from Inner Mongolia), MOF003 (yellow flowers from Ningxia), MOF001 (yellow flowers from Gansu), MOF002 ( From the Jilin Province of the yellow flowers clogs), MIN001 (from Jiangsu, Indian grass clogs), the annual crude protein production in the order of MOF001> MAL001> MAL002> MOF003> MOF002> MIN001. Through the GI index, the nutritional qualities of six species of M. chinensis were compared comprehensively, and the nutritional value was MOF002> MIN001> MAL001> MOF001> MAL002> MOF003. According to the comprehensive nutritional quality and performance evaluation, MAL001 most suitable for cultivation in Alar, followed by MAL002.
