摘要
通过对15个杂交种及其22个亲本自交系的茎秆热值及其化学组分的测定,结果表明:秸秆热值与秸秆产量和子粒产量关系密切;不同材料间、同一材料不同部位间的热值及半纤维素、纤维素、木质素含量存在差异;同一材料的热值及纤维素、木质素含量从上部到下部逐渐增多,半纤维素含量逐渐减少;热值与纤维素、木质素含量间有密切相关回归关系,其回归方程为Y=10523.6+13273.4X1+15908.9X2,初步确定纤维素、木质素作为秸秆的主要能量指标;根据热值、产量性状结果,认为豫玉25、沈单16、农大108和豫玉34是目前生产上可以大面积推广的高热值、高产的理想品种。
By the analysis of the calorific value and chemical component of maize stem from15hybrids and22parent inbred lines,the result indicated as the following:the calorific value of stem has consanguineous relation with yield of stem and seeds;the calorific value,hemicellulose content,cellulose content and lignin content were different in different material and different part of same material.Calorific value,cellullose content and lignin content from the upper to the lower increased gradually,but hemicellulose content decreased gradually in same material;calorific value has consanguineous correlation and regression with cellulose and lignin content,the regression equation is Y=10523.6+13273.4X 1 +15908.9X 2 ,cellulose and lignin are confirmed the main energy indexes of stem.With the results of calorific value and yield characters,Yuyu25,Shendan16,Nongda108and Yuyu34are ideal varieties with the characters of high calorific value and high yield,which they can be popularized in production.
