摘    要:针对干旱半干旱地区农田土壤中水分缺乏,肥料过度使用的问题,从减少养分损失,提高养分利用率出发,对施用缓释型保水剂、保水剂、常规肥料下油菜生长状况和土壤性状进行了研究.结果表明,缓释型保水剂为植株提供适宜的水分条件和营养条件,促进了作物生长;缓释型保水剂具有保水和持水性能,同时改善了土壤物理性状,使土壤孔隙数量增加,降低土壤容重;缓释型保水剂具有持续供应养分的作用,施用缓释型保水剂后土壤中速效氮素养分增加,能持续释放养分.土壤剖面中硝态氮淋失的也较少,有一定的保肥作用.

关 键 词:缓释型保水剂  油菜  土壤性状

Abstract:In view of the problems of moisture shorting and fertilizer overspending in arid and semi-arid areas and the aims of reducing fertilizer loss and improving nutrient use efficiency, water-retaining reagent of relaxed releasing ,water-retaining reagent and routine fertilizer were employed to investigate rape growth and soil properties. The result showed that water-retaining reagent of relaxed releasing provides fitting conditions of moister and nutrition for the plant and improves rape growth, it also has the capability of retaining and holding soil water simultaneously, it improves physical properties of the soil and increases the pore amount in soil. Water-retaining reagent of relaxed releasing possesses continuously accommodation of nutrient. After use of water-retaining reagent of relaxed releasing, available nitrogen would be more than other treatment and NO3^-1 -N etuviating would be smaller than other treatment in soil profile.
Keywords:water-retaining reagent of relaxed releasing  rape  soil properties
