摘　　要：研究不同浸种剂处理下油莎豆盐碱地萌发及幼苗生长的差异,筛选适宜浸种剂,为盐碱地油莎豆栽培种植提供实际理论依据。在田间盐胁迫条件下,选用氯化钙、水杨酸、S-诱抗素、赤-吲乙芸苔、复硝酚钠、芸苔素内酯6种不同浸种剂处理油莎豆块茎,通过统计田间出苗情况并调查苗期农艺性状,分析不同浸种剂处理后盐碱地油莎豆萌发和幼苗生长的差异,进行综合评价。结果显示,芸苔素内酯处理出苗势最大,为69.33%;其次是水杨酸处理,为64.67%,比CK (清水)处理分别提高了70.47%和59.01%;各处理出苗率较CK均有提高。多重比较结果显示,水杨酸处理苗高、叶片数、SPAD值、叶片干重4个指标均为最大且显著高于对照;计算不同处理各指标隶属函数值及平均隶属函数值并进行排名,由高到低排序为水杨酸、芸苔素内酯、氯化钙、S诱抗素、赤-吲乙芸苔、复硝酚钠、清水。药剂浸种可不同程度缓解盐害,促进油莎豆盐碱地出苗和生长,其中以0.5 mmol/L水杨酸浸种处理效果最佳。We studied the differences in germination and seedling growth of Cyperus esculentus under different soaking agent treatments in saline alkali soil,selected suitable soaking agents,so as to provide practical theoretical basis for the cultivation and planting of Cyperus esculentus in saline alkali soil.Under salt stress conditions in the field,six different soaking agents of calcium chloride,salicylic acid,S-inducer,indole-3-acetic acid,sodium nitrate and brassinolide were used to treat the tubers of Cyperus esculentus.Through statistical analysis of field emergence and investigation of agronomic traits during the seedling stage,the differences in germination and seedling growth of Cyperus esculentus in saline alkali soil after different soaking agents treatment were analyzed,and a comprehensive evaluation was conducted.Results showed that the treatment with brassinolide had the highest emergence rate,which was 69.33%,followed with salicylic acid treatment,which was 64.67%,they were 70.47%and 59.01%higher than CK(clean water treatment),respectively.The emergence rate of each treatment has increased compared to CK.Multiple comparison results showed that the four indicators of seedling height,number of leaves,SPAD value and dry weight of leaves treated with salicylic acid were the highest and were significantly higher than those of CK.We calculated the membership function values and average membership function values of different indicators for different treatments,and ranked them in a descending order of salicylic acid,brassinolide,calcium chloride,S-inducer,indole-3-acetic acid,sodium nitrite and water.Soaking seeds with pesticides could alleviate salt damage to varying degrees and promote the emergence and growth of Cyperus esculentus in saline alkali soil.Among them,soaking seeds with 0.5 mmol/L salicylic acid had the best effect.
