湖南地区不同生育期禾本科植物营养品质分析
Analysis of Nutritional Quality of Poaceae Plants at Different Growth Stages in Hunan Province
摘要
Abstract
In order to explore the nutritional quality of Poaceae plants in Hunan and select high-quality Poaceae plants,different Poaceae plant germplasm(17 in vegetative period,25 in flowering period,19 in maturation period)were collected in Hunan.Dry matter,nitrogen-free extract,Ash,crude fiber,ether extract,and crude protein content were determined,and a comprehensive evaluation was analyzed accord-ing to Grey Correlation Degree.The results showed that during the vegetative period,the 17 germplasm contained 23.02%-83.33%dry matter,4.55%-11.37%crude protein,1.09%-3.88%ether extract,28.63%-44.05%crude fiber,5.00%-12.03%Ash,and 34.47%-48.70%nitrogen-free extract.25 germplasm during the flowering period contained 13.59%-46.58%dry matter,3.85%-15.65%crude pro-tein,1.01%-3.89%ether extract,25.69%-49.42%crude fiber,5.59%-45.36%Ash,and 12.87%-52.06%nitrogen-free extract.23.97%-84.26%dry matter,4.96%-29.14%crude protein,1.45%-4.86%ether extract,22.80%-41.98%crude fiber,7.26%-15.34%Ash,and 30.89%-59.26%nitrogen-free extract were determined in 19 germplasm during the maturation period.The comprehensive evaluation results showed that during the vegetative period,Microstegium vimineum,Miscanthus sinensis,and Setaria plicata performed better with higher nutritional quality;during the flowering period,Spo-robolus fertilis,Paspalum wettsteinii,and Microstegium nudum exhibited superior performance and better nutritional quality;at maturation,Bromus japonicus and Arundinella fluviatilis performed better with higher nutritional quality..关键词
