摘要
通过对100 cm深度土壤的盐分分布状况以及作物产量进行分析,结果表明,3 g/L的微咸水可以作为小麦和玉米的灌溉用水,但连续使用会导致土壤发生积盐,组合灌溉最好采用咸淡交替的方式;综合土壤的积盐状况和作物产量分析,淡淡咸的组合灌溉顺序为最优方案。
The salinity distribution of soil section was discussed and crop yield was analyzed at the same time,the result indicated that the saline water with 3 g/L mineralization could be used as irrigation water of winter wheat and summer maize,but the salt would be accumulated in the soil of 100 cm depth;fresh-saline water alternately is the suitable method of rotational irrigation;fresh-fresh-saline is the optimal mode in consideration of both the soil salt accumulation and the crop yield.
