Sun Xilian, Zheng Wenzhong
2014, 4(3): 159-162.
Abstract(488) [PDF 512KB](85)
Abstract:
According to the statistics of total grain output in Zhejiang province from 1995 to 2012，six indexes，such as grain planting area，chemical fertilizer rate，application amount of pesticides，effective irrigation area，agricultural machinery gross power and agricultural labors were chosen as influencing factors for total grain output.Correlation between six indexes and total grain output was analyzed by using gray relation methed.Results indicated that relevancy order of which had an impact on the total grain output was agricultural labors 0.862 9，grain planting area 0.858 8，chemical fertilizer rate 0.796，application amount of pesticides 0.680 7，effective irrigation area 0.597 3 and agricultural machinery gross power 0.553.Consequently，enlarge planting area and increase agricultural machinery for agricultural labors are the most important measures to realize sustainable development of grain output in Zhejiang province.

Abstract(519) [PDF 388KB](101)
Abstract:
In order to improve the performance of off-road vehicle and working efficiency of machines used in the field of construction and agriculture，the mechanism of soil adhesion should be understood.The purpose of this study was to find out the relationship between tangential soil adhesion and moisture content using different tool materials and investigate the effect of tangential soil adhesion on mechanical properties of soil shear.In the experiment，three kinds of experimental material：rubber（RUB），steel（SS400）and resin（PEEK）were provided for direct shear test.The experimental results showed that tangential soil adhesion between soil and material increased with the increasing of soil moisture content until reached a maximum value thereafter decreased.Tangential soil adhesion was largest with steel（SS400）followed by rubber（RUB）and resin（PEEK）.It was also shown that external friction angle between three kinds of tool material and test soil first decreased with the increase of moisture content，then tended to increase gradually thereafter showed a decreasing tendency after reaching peak value.The changes of tangential adhesion caused by the difference of soil moisture content directly affected shear stress and external friction angle while shear happened.
