Test Research On The Applicability Of 1SZL Subsoiler In Semi-arid Area Of ??Xinzhou City

Nowadays,with the evolution of agricultural production technologies and development patterns,conservation tillage is getting ever important.Subsoiling is one of the popular conservation tillage methods.It can help improve soil structure and soil texture effectively.Loosening and breaking up soil at depth without disordering soil original structure is able to increase water storage,which enables different factors of soil to work together.The target of increasing yields will be achieved in the end.At the moment our country is still at the primary stage of subsoiler research.Due to design limitations,products can't be used widely.It's difficult for farmers to choose a right subsoiler.This problem is to be addressed.The fundamental way is to study the applicability of subsoiler to the soil.This study is focused on the analysis of the applicability of 1SZL mode subsoiler to semi-arid areas of Northwestern Shanxi Province(Xinzhou as research object)by coming up with measure ways and carrying out field test.Combining with field research of Xinzhou northwestern semi-arid areas,this study analyzes geological data,climate,soil as well as drought levels.In the meanwhile,the usage of agricultural tools,function test on fields and the influence of external factors are also taken into analysis.It is found out that soil moisture content and soil hardness have significant effects on subsoiling.Based on practical research and the above field test results,the applicability is mainly affected by soil moisture content and soil hardness.Research results are as follows: loosening soil depth – 33.1 cm(25 test points,100% pass),stability 89.9%(25 test points,100% pass),pulverizer rate 70.6%(25 test points,100% pass),soil fill power 33.7(25 test points,100% pass)and soil disturbance rate 64%(25 test points,100% pass).The above research data advises that the applicability of subsoiler is 84.37.Therefore,the applicability has been verified.
