摘　　要：研究了辐照合成新型土壤保水剂在芦笋上的应用效果。盆栽试验结果表明:施用保水剂可有效增加芦笋茎数,提高芦笋茎粗,湿施处理生育指数比对照增加53.9%～77.0%,干施处理生育指数比对照增加5.8%～38.7%。大田试验结果表明:湿施保水剂的芦笋株高、株数、茎粗和生育指数分别比对照提高14.2%、12.5%、23.8%、59.0%,湿施保水剂的大田芦笋产量比干施和对照分别提高0.6%和32.7%。The application effects of new type soil water-retaining agent,which was synthesized through irradiation,in asparagus were studied.The results of pot experiments indicated that the use of water-retaining agent could increase the stem number of asparagus effectively,and enhance the stem width;comparing with the control（CK）,the growth index of asparagus in water-retaining agent wet-application treatment was increased by 53.9%~77.0%,and that in dry-application treatment was increased by 5.8%~38.7%.The results of field tests showed that the plant height,plant number,stem width and growth index of asparagus in wet-application treatment were increased by 14.2%,12.5%,23.8% and 59.0% respectively as compared with those of CK;the yield of asparagus in wet-application treatment was 0.6% and 32.7% higher than that in dry-application treatment and CK,respectively.
