摘要
以大田试验为基础,研究了不同保水剂种类(中大号、大号和超大号)对旱作马铃薯产量形成及农田土壤水分特性的影响.结果表明,施用不同类型的保水剂均能显著提高马铃薯的田水分利用效率(WUE),与不施保水剂相比较,WUE分别提高了28.70%、50.35%和45.51%,以大号(2101L型)保水剂处理下的最高;施用保水剂明显降低了马铃薯薯块的小薯率和烂薯率,提高了大薯率、中薯率和单株薯质量,其产量比对照分别提高59.68%、60.49%和36.29%,亦以大号保水剂处理下的产量最高.
Effects of different aquasorbs on soil water characteristic and yield formation of potato were studied on the basis of field experiments.The result showed that WUE of application of aquasorbs treatments were increased by 28.70%,50.35% and 45.51%,respectively,compared to without application of aquasorbs treatments.And WUE of application 2101L aquasorb was highest.The small tuber rate and blemished tuber rate of potato were decreased by application of aquasorbs,whereas the big tuber rate,middle tuber rate and tuber weight per plant increased.The yield of potato were increased by 59.68%,60.49% and 36.29%,respectively,compared to without application of aquasorbs treatments,and yield of application 2101L aquasorb treatment was highest.
