查询词典 irrigation engineer

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。
