查询词典 irrigation engineering

In abandoned land and peripheral desert of oasis, influenced by irrigation of oasis, groundwater table has been raised above the critical depth.Because the soil salt cannot be eluviated by irrigation water and precipitation, salt brought to the upper layers of soils by strong evaporation is especially concentrated on soil surface.

绿洲内的撂荒地和靠近绿洲的荒漠草地受绿洲内部灌溉过程的影响，地下水位升高，超过了地下水的临界深度，同时又因为缺少灌溉的反复淋洗，在强烈的蒸发作用下，盐分的表聚现象十分明显，而且整个剖面内盐分的含量都较高，土壤的盐渍化现象非常严重。

Show that the 1 lateral 4 rows and 2 laterals 4 rows to increase the volume of nitrogen fertilizer and irrigation will help improve cotton yiled, with 2 laterals 6 rows increased irrigation and fertilizer control in favor of increasing cotton yiled.

综合分析，AFI最能有效降低棉花根区硝态氮损失，使硝态氮和铵态氮含量主要分布在棉花根系有效吸收范围内，有利于棉花氮素吸收和利用。

One reason why AIFU has the best spatial coupling effect is that it has a smaller evaporation area, thus its wate loss by this way is much smaller that traditional full irrigation; leching of fertilizer nutrients is much less than traditional irrigation because fertilizer and irrigating water exists in different furrows, the residual fertility exists in above 60 cm soil profile.

水肥异区交替灌水为一种局部灌水方式，其能够提高水分利用率的原因是可减少蒸发面积，从而减少灌溉水的蒸发损失；对养分的淋溶损失少，使肥料养分主要存在于60cm以上土层。

This article deals with problems of irrigation frequency and crop-water production function of cotton under mulched drip irrigation in agriculture production.
