棉秆拉拔阻力的研究
Research on the Cotton-Stalk Uprooting Resistance
摘要
Abstract
In order to study the cotton-stalk uprooting resistance influenced by the cotton-stalk root diameter and the soil hardness , and thereby to provide reference for the design and use of cotton-stalk uprooting harvester , cotton-stalk uproo-ting experiment was taken artificially in cotton full mechanization demonstration base in Wudi district ,Shandong Province . Experimental results show that , in a long time interval , the cotton-stalk uprooting resistance changes greatly , first in-creased and then decreased .Among the 6 batches of sampling data , the largest cotton-stalk uprooting resistance ap-pears in the second batch (2014-12-26), the maximum uprooting resistance of single cotton-stalk is 1 031.6N, and the average uprooting resistance is 679.0N, the smallest cotton-stalk uprooting resistance appears in the sixth batch (2014-12-26),the maximum uprooting resistance of single cotton-stalk is 471.1N,and the average uprooting resistance is 340.76N.Regression analysis of the sampling data shows that , during the same period , the cotton-stalk uprooting resistance is positive correlation to the cotton-stalk root diameter and the soil hardness , both of the linear re-gression relationships are not significant .关键词
