棉秆剪切力与营养成分含量之间的相关关系
Correlations between Shearing Force and Nutrient Contents of Cotton Stem
摘要
Abstract
This experiment was conducted to study the correlations between shearing force and nutrient contents of cotton stem. Cotton stems were cut into three parts at 1/3 from bottom (bottom 1/3), 1/3 in the middle ( middle 1/3) and 1/3 from top ( top 1/3) , respectively. The mass and length of different parts were tested, and the linear density was calculated; the shearing force and main nutrient contents of stem and lateral branch were determined. The results showed as follows:the linear density and diameter increased from top to bottom, and the differences among three parts were significant ( P<0.05); crude protein content of whole cotton stem was 8.78%;neutral detergent fibre content in stem bottom 1/3 was the highest (62.54%), while that in cotton leaves was the lowest (35.51%); crude protein and ash contents had negative correlations with shearing force ( P<0.001); dry matter, neutral detergent fibre, acid detergent fibre and hemicellulose had positively correla⁃tions with shearing force ( P<0.001) . In conclusion, in different parts of cotton stem, shearing force is mainly affected by diameter and nutrient contents, and strong linear relationships exist between shearing force and nu⁃trient contents.关键词
