The Adaptability Study Of All-round Deep Loosening Technology To Different Areas In Shanxi

70%of the cultivated land in Shanxi Province is arid low-yielding fields. The traditional farming methods have seriously restricted the sustainable development of our province’s dryland agricultural production. How to solve the province’s high-yield food and sustainable agricultural development has become an urgent problem. This paper mainly analyzes the development status of domestic and foreign subsoiling technology, combined with our province of dryland agriculture tillage methods in the actual situation. In our province we chose three different areas of geographical tillage techniques to carry on the subsoiler experimental research.In this study, we contrasted the cultivated land between a full range of subsoiling plots and traditional tractor operations control field. The results shows that:(1) The effects of subsoiling on soil physical properties. The subsoiler after (xiangfen test points), soil bulk density in0cm～40cm decreased by0.14g/cm3, the average porosity increased by4.3%, in severe drought, rainfall is only17.4mm, the moisture content was increased by12.1%; determination in Liulin test of soil deep loosening after half an year, soil infiltration rate5-10times, it can effectively improve the drought resistance of soil, and prevent soil erosion.(2) The effect of soil salinity subsoiler in technology. All-round loosening technology is a very effective measure to reduce the salt content of soil and prevent the return of saline, the heavy saline alkali land measured in Dingxiang county is reduced by an average of23%in the0cm～40cm soil salt content, this is because the deep loosing broke years of plough layer, soil structure into "under the virtual reality, left and right elastic phase, a ditch at the bottom of soil", the soil physical properties change is more suitable for the crop growth.(3) The effects of the full range of subsoiling technology on crop growth and yield. Experiments show that after deep loosing, the soil is improved, soil fertility enhanced, crop root system growing stout, post-harvest yield monitor, wheat yield is increased10%, cornyield about20%, cotton production about14%of, millet yield increased about18%, the effect of increasing production and income received.This study demonstrates that the omnidirectional subsoiling technology plays an important role in arid and low yielding fields in our province, which is an important technology of mechanized protective tillage, suitable for implementation in the promotion of our province, and has important significance to increase the province’s agricultural production and sustainable development.
