The Effects of Combining on Chemical Composition and Morphology of Cereal Straws
Harvesting of five wheat straws,two barley straws,four oats straws,and four triticale straws grown in Alberta were conducted by hand and a Nursery Elites combine in 2006.The results of the chemical composition and morphological properties of the cereal straws indicate that comparing with the hand-harvested straw the combined straw had higher cellulose content,lower ethanol-benzene extractives and hot water extractives content.Compared with hand-harvested straws,the average increase of cellulose content of the combined straws was 2.61％ while the average decrease of ethanol-benzene extractives and hot water extractives content of the combined straws was 1.25％ and 1.74％,respectively.No rules were found on the effects of combining on the acid-insoluble lignin,pentosans,ash,and silicates and silica content.After combining,the standard deviation of the changes of ash,silica and silicates,and acid-insoluble lignin,and pentosans content was 0.52％,0.41％,0.49％,and 1.24％,respectively.The effects of combining on the fiber length,width,and coarseness were found not significant.
