NS had higher respiratory quotient at 10~20cm, thus younger microbiology, and CN had younger microbiology at 0~10cm. This was good to sustain soil qualified characters and sustainable potentiality. This showed that mechanic tillage and biological tillage were of the same importance in some degree. It was important for reducing energy cost to enhance the effect of microbiology in soil nutrtient transferring.

免覆在10~20cm土层呼吸商较高，微生物年轻化，常无在0~10cm土层微生物年轻化，对维持土壤的优良性状和可持续利用潜力有益，这在一定程度上说明机械耕地和生物耕地的同等重要性，充分提高土壤微生物在养分转化中的作用对于降低农业生产中的能耗有重要意义。

To further explore tillage practices for improving soil structure, the effect of different tillage practices on the structure and organic carbon of tilth soils were investigated using routine method (Wet-sieving, Potassium dichromate volumetry and Core-cutting sampling).

为了寻求能够提高土壤结构稳定性的耕作模式，在陇中黄土高原半干旱区连续7年的定位试验研究基础上，采用常规分析方法(湿筛法、重铬酸钾容量法、环刀法)，研究了不同耕作方式对耕层土壤结构性能及有机碳含量的影响。

The results showed that the structure characteristics of block cloddy was with tight surface but loose inner, the bulk density of the crust can be high as 1.39~2.0g/cm^3, which was mainly affect by unreasonable tillage process. The tight surface can not be crushed by nature alternation of drying and wetting. Farming machinery to impact and rotary tillage were necessary when reduce them.

结果表明不合理耕作所产生的块状结构体具有外部极为密实而内部相对疏松的构造特征，外壳的容重高达1.39~2.0g/立方公分以上，仅依赖于自然干湿交替作用使其碎散成小的土团成为不可能，必须运用机械击打、旋耕切割等方法进行破碎。

Compared with the no-tillage planter for wheat and corn no-tillage planter difficult to develop a large amount of corn stalks, thick stubble; easy is a wide spacing of maize (55 ~ 70cm), is conducive to the layout block device .

相对于小麦免耕播种机来说，玉米免耕播种机开发困难的一面是玉米秸秆量大、根茬粗大；容易的一面是玉米行距较宽（55～70cm），有利于防堵装置的布置。

No evident regularity was found in the depth from 15 to 30 cm. There was an obvious accumulation of OM and TN in the top 30 cm of the fallowed soils, of which the accumulation of OM was faster than that of TN and there was more accumulation in no-tillage compared to tillage. Soils applied with inorganic and organic fertilizers had much more OM and TN at 0～5 cm and 5～15 cm depth than soils applied with only inorganic fertilizers and soils without fertilization. However, OM and TN in these treatments were less than that in fallow treatment. No significant differences in OM and TN contents were found between fertilization treatments. Only in the 5 cm of top soils, OM and TN of the soils treated with only inorganic fertilizers were more than that of CK.

长期休闲的土壤在整个耕层有明显的有机质和氮素累积，其中碳的累积快于氮的累积，免耕条件下比耕翻条件下累积量更大。0～5 cm和5～15 cm土层有机肥与无机肥配施的处理，其有机质和全氮质量分数均显著高于单施化肥处理和不施肥处理，但均低于休闲处理；15～30 cm土层各培肥处理则无明显差异；单施化肥的土壤有机质和全氮质量分数高于不施肥处理，但这种差异只在表层（0～5 cm）较显著。

While traditional farming experiences and preliminary experiments on minimum tillage showed a preference of alternating furrow slice inverting and deep loosening without inverting in some of the agricultural regions in China, the development of a PTO driven furrow slice inverting rotary plow as primary tillage implement inplace of the conventional moldboard plow was justified from the standpoint of less tractor traffic, less soil compaction, less energy consumption, sowing in time etc.

从翻耕或翻耕与深松相交替将在相当广大的地区、相当长的时期内，作为一种基本的田间作业环节而存在这一认识出发，用&假想旋翻垡片&的概念研究了旋翻在几何尺寸上的可能性及其限制条件，并从保省耕作法的节能、赶农时、省人工减少土壤压实、经济高效等方面对旋翻进行了考察，指出发展一种动力驱动、原沟旋转翻垡的基础耕具的必要性和可行性。

In order to improve the water use efficiency under conservation tillage, the effects of subsoiling on soil moisture under no-tillage 2 years later was studied.

研究两年免耕后深松对土壤水分的影响，提高保护性耕作条件下对土壤水分的利用效率。

Subsoiling under no-tillage is an effective rotation tillage to content of more soil moisture and improvement of water use efficiency in ecotone of north China.
