When the mevinphos was utilized for a long time in highland barley field, the young-root of next-season cole shortened 1.9~2.0cm and fresh weight decreased 0.13~0.14g per individual plant compared with the control. Low-tillage in time after autumn-harvest showed that the weed seeds in the ground surface were harrowed into the tilth of 0~10cm. Early-low-tillage in spring-sow of the next year induced weed seeds of soil surface to germinate and come out ahead. After 10 days, tillage-sow can decrease about 40% weeds. Compared to the normal plough-row, direct late-tillage-row was postponed 10 days, and can decrease about 30% weeds. In the seedling period or later, rudimental weed seeds were handled with a hoe, which led to better cure and control effects and had more benefits to the young seedling growth and yield of the next-season crop.

研究结果表明：氟乐灵在油菜田长期使用时，土壤残留农药抑制下茬青稞幼根生长，幼根较对照株缩短3.0~3.1cm/株，鲜重量减少0.19~0.20g/株；甲磺隆在青稞田长期使用时，下茬油菜幼根较对照株缩短1.9~2.0cm/株，鲜重量减少0.13~0.14g/株；秋收后及时浅耕可将落入地表的杂草种子全耙入0~10cm耕层内；翌年春播早浅耕可诱发土壤表层的杂草种子提前萌发出苗，10d后耕种，能防除40%左右的杂草株数；较正常播种期推迟10d后直接晚耕播种，可防除30%左右杂草株数；苗期或后期拔出残余杂草种子时，除草效果理想，对下茬作物幼苗生长发育及产量无任何不良影响。

An earthquake nucleates and happens not only as a result of increments and changes in back ground tectonic stress field, but also as a result of stress changes in the focal region, so seismic wave velocity and attenuation contain information on stress changes of the Earth's interior as a result of changes in the physical state of materials.
