water tillage

This paper analyses soil and water conservation of tillage measures, with reference to rainfall influences.

从径流能量入手, 在室内人工降雨试验的基础上,分析了坡面耕作措施对径流能量的削减作用.

In order to examine the effect of alternative tillage practices on crop yield, water conservation and soil loss, a field study was conducted over a period of 6 years.

在模拟降雨和自然降雨条件下研究长期（6年）定位耕作措施对豫西旱区坡耕地水分保持、土壤流失以及冬小麦产量的影响。

The results were shown as follows: 1. After water-cultivation and dry cultivation, along with the no-tillage years increasing, the content of soil bulk first increase and then decrease and reincrease.

研究结果如下：1.水作及早作后，随免耕年限延长，土壤容重均呈先增加后降低的变化趋势。

Thereby conservation tillage is availably measure to control soil and water losses of semi-arid area sloping fields. Conservation tillage can increase agricultural efficiency and farmers to achieve sustainable development of agriculture.

因此，保护性耕作是控制黄土高原半干旱区坡耕地水土流失的有效措施，保护性耕作可以实现农业增效和农民增收，实现农业的可持续发展。

As a consequence of the above, integration technique of ridge tillage and covering film between furrows measure has the best effect on water saving and yield increasing in this area.

由此综合以上结果可得出，行间覆膜与垄向区田集成措施为黑龙江西部风沙土区节水增产最有效的保护性耕作措施。

The results indicate that the degree of iron activation are greatly increased in the A horizon of the soil due to water tillage and manuring, therefore the dissipative structure of system's symmetry breaking are proved on the point of soil profile development.

研究表明，其A层因渍水耕作和施肥，使铁活化度大幅度增高，以土壤剖面发生学论证了土层对称性破缺的耗散结构。
