1998～ 1999年以湘麦 13号为材料 ,研究了超强吸水材料 SP与营养液和水的配合使用对小麦的出叶情况和群体动态变化的影响。结果表明 :SP+肥的处理比对照提前 7d出苗 ,提前分蘖2 0 d,平均出叶天数比对照少 6.5d,主茎总叶片数多 1.2 5片 ,每平方米有效穗数多 2 2 3株 ,每平方米产量高 75.5 g,均显著或极显著高于对照。作为实施节水农业的新材料 ,SP可在干旱地区和干旱季节广泛试验与应用。
From 1998 to 1999, the effects of combination of super absorbent material SP with nutrient solution and water on wheat leaf emergence and population dynamics were studied using Xiangmai 13 as material. The results showed that the treatment of SP + fertilizer was 7 days earlier than that of the control, with 20 days early tillering, the average number of leaves was 6.5 days less than the control, the total number of main stems was 1.2 5, and the number of effective spikes per square meter was 223, , 75.5 g per square meter high yield, were significantly or very significantly higher than the control. As a new material for implementing water-saving agriculture, the SP can be extensively tested and applied in arid regions and in the dry season.
