In 1987 we set up three experimental fields in Toyohashit Aichi-ken: 1) 1.5 meter super deep ploving plot 2) 1.0 meter deep ploving plot 3) Customary plot and did dynamic penetration test, static penetration test as well as soil hardness test. As a result it is confirmed that in the super deep and deep plowing plot the measurement value vas extremely low compared with the customary plot. Also it became clear from the measurement of pF-soil moisture curve and the measurement of the three phase distribution of soil that macro pore and air ratio increased by deep plowing and solid ration decreased. This influence also appeared on the result of the penetration test i.e. the value increased extremely in the super deep plowing plot deep plowing glot. The result of the particle test showed that in contrast to the multi stratification of the customary plot, the particle component equalized in 1.0 meter and 1.5 meter deep plowing plot in all strata. Also the consistency test revealed that while … More in the customary plot the liquid limit and the plastic limit changed according to the depth and correspond with the stratification of the particle size distributions the change of the value were few in the 1.5 meter deep plowing plot.From the view point of chemical side of soil, though the many type of effective components were extremely unequalized just after the deep plowing treatment it was gradually equalized in accordance with the strata with the lapse of time. This was especially remarkable in the super deep plowing plot. In the super deep plowing plot, high density distribution pattern of many type of effective components appeared somewhere around 90 - 100 centimeter area. Also the illuviation from the result of declination of fine particle of soil could be found.The result of the yield test of cabbage done in 1988 - 1989 showed the yield became bigger in order of 1) super deep plowing plot - 1.5 meter 2) deep plowing plot - 1 meter 3) customary plot From the above it is clear that the deeper the plowing the more yield could be expected.

1987年，我们在丰桥爱一垦建立了3个试验田：1)1.5米超深耕地2)1.0米深耕地3)常规耕地，并进行了动态贯入试验、静态贯入试验和土壤硬度试验。结果证实，在超深耕和深耕地块，测量值与常规地块相比极低。土壤湿度曲线的测定和土壤三相分布的测定也表明，深耕增加了宏观孔隙比和空气比，降低了固体比。这种影响也出现在贯入试验的结果上，即在超深耕地和深耕地，该值急剧增加。颗粒试验结果表明，与常规样地分层不同，1.0 m和1.5 m深耕样地各层颗粒成分均相等。一致性试验表明，在常规耕作区，液限和塑限随深度变化较多，并与粒径分布的分层相对应，而在1.5 m耕作区，液限和塑限变化较少。从土壤化学方面来看，虽然刚开始深耕处理后土壤中多种有效成分极不均衡，但随着时间的推移，土壤各层有效成分逐渐均衡。这在深耕的土地上尤为显著。在超深耕田，在90 ~ 100 cm的区域内出现了多种有效成分的高密度分布格局。从土壤细粒偏角的结果也可以得到启示。1988 ~ 1989年大白菜产量试验结果表明，大白菜的产量依次为：1)超级深耕地—1.5米；2)深耕地—1米；3)习惯耕地。由此可见，深耕地越深，产量越高。少
