应用灰色关联度分析法综合评价啃食强度对紫穗槐营养价值的影响
Applying grey correlative degree analysis to comprehensively evaluate the influence of different defoliation intensities on nutritional value of Amorpha fruticosa
摘要
Abstract
The influences of nutritional quality on Arnorpha fruticosa were studied using five simulated defoliation intensities (20%,40%,60%,80%,and 100% proportion of aboveground vegetation).The grey correlation degree method was used ta comprehensively analyze seven nutritional indexes;crude ash (Ash),neutral detergent fiber (NDF),acid detergent fiber (ADF),water-soluble sugar (WSC),crude protein (CP),phosphorus (P),and potassium (K).When the defoliation intensity of A.fruticosa was 40%,the weighted grey correlation degree of leaves and stems was 0.781 2 and 0.651 3,respectively.This was larger than that of the other defoliation intensities.A.fruticosa had the best nutritional value with the 40% defoliation intensity treatment.关键词
