摘要/Abstract

摘要： 为探讨不同玉米品种秸秆饲用品质状况,本研究采用近红外光谱技术,分析评价了44个玉米品种秸秆的体外干物质消化率(IVDMD)、酸性洗涤纤维(ADF)、中性洗涤纤维(NDF)和可溶性糖(WSC)含量4个品质性状。结果表明,品种间IVDMD、ADF、NDF和WSC含量存在极显著差异,44个玉米品种秸秆各品质性状近似正态分布,其变化范围分别为38.60%~51.74%(IVDMD)、27.01%~35.67%(ADF)、51.55%~65.81%(NDF)和4.69%~12.21%(WSC)。各性状变异程度不同,WSC含量变异系数最大,达23.59%。相关分析表明,IVDMD与ADF和NDF含量极显著负相关,与WSC含量极显著正相关,ADF含量与NDF含量极显著正相关,WSC含量与NDF和ADF含量极显著负相关。根据各性状的相关关系,筛选出5个秸秆IVDMD和WSC含量高而ADF和NDF含量低的玉米品种。

Abstract: Maize stover is the important resource as forage. With technique of near infrared reflectance spectroscopy, forage quality traits such as in vitro dry matter digestibility(IVDMD), acid detergent fiber(ADF), neutral detergent fiber(NDF)and water soluble carbohydrate(WSC) of maize stover about 44 varieties were evaluated. The Results showed that there were significant differences in IVDMD, ADF, NDF and WSC among varieties. The four forage quality traits were almost accorded with normal distribution respectively. IVDMD ranged from 38.60% to 51.74%, ADF ranged from 27.01% to 35.67%, NDF ranged from 51.55% to 65.81% and WSC ranged from 4.69% to 12.21%. The coefficient of variation(CV)of WSC was the highest which was 23.59%. IVDMD was significantly and negatively associated with ADF and NDF, and positively associated with WSC. There was a significantly positive correlation between ADF and NDF. WSC was significantly and negatively associated with ADF and NDF. There were five elite varieties with high IVDMD and WSC and low ADF and NDF.
