摘  要:
2005年在黑龙江省甘南县进行了节水集成技术(振动深松技术+机械化暗式坐水种技术+苗期补灌技术+坡耕地垄向区田技术)对土壤含水量及其大豆产量影响的试验研究,在全生育期对土壤水分指标及大豆产量进行了观测,对观测数据进行了统计分析。并采用基于熵权的灰色关联法对不同的试验处理进行了综合评价。结果表明:节水集成技术可有效地提高土壤含水量,具有较好的节水作用,同时大豆产量以及水分利用效率增加显著;振动深松和垄向区田情况下的处理6(坐水量83.07 m3/hm2,补水量120 m3/hm2)为最优。

摘  要:
The experiments about the influence of anti-drought and water-saving technologies assembling(subsoil vibrating,bed-irrigating sowing,seedling stage mending irrigation,and ridge plotted field) on soil-water condition and yield of soybean were conducted in Gannan county Heilongjiang province in 2005.The yield and soil water in the whole bearing period were observed and analyzed.And grey relevancy theory based on coefficients of entropy was used for different treatment evaluating.The experiments results indicate that: water-saving assemble technology can improve soil moisture and has better effect on water saving.Meanwhile,it has a higher effect on yield and water use efficiency improving.In 2005,under the condition of subsoil vibrating and ridge plotted field technologies assembling,the treatment 6(the amount of bed-irrigation and seedling stage mending irrigation are 83.07 m3/hm2 and 120 m3/hm2 respectively) is the best.
