摘要:

为探究在不同功能性肥料浸种对棉花种子萌发及抗盐碱能力的影响,筛选出适宜新疆盐碱地棉花种植的最佳功能肥料,设置2种浓度(0、50 mmol/L Na2SO4)的盐分胁迫,处理组为4种功能性肥料(肽氨基酸、黄腐酸、聚谷氨酸、海藻寡糖)和7种复配方案及对照组CK,测定发芽势、发芽率、发芽指数、鲜重、干重、下胚轴长和根长等7个性状指标,结合相关性分析、主成分分析、隶属函数法,对棉花耐盐性进行综合评价。结果表明:(1)与无盐各处理相比,低盐各处理下的平均发芽势、发芽率、发芽指数分别提高了58.87%、45.48%、43.08%;但低盐处理下各处理降低了鲜重、胚轴、根长指标,分别为39.00%、57.22%、42.14%。(2)与CK相比,T9处理下的发芽势、发芽率、发芽指数差异显著(P<0.05),分别提高了94.43%、76.66%、84.75%;而T7处理下的鲜重、胚轴、根长显著高于CK(P<0.05),分别提高了5.58%、21.56%、4.46%。与SK相比,ST8处理下的发芽势、发芽率、发芽指数分别提高了41.95%、27.27%、29.09%;而ST11处理下的鲜重、胚轴和根长显著高于SK处理(P<0.05),分别提高了6.99%、42.74%和108.00%。(3)相关性分析表明,发芽率是评价萌发耐盐碱能力的重要指标;主成分分析将7个指标转化为3个独立综合指标,累积贡献率为81.668%。根据耐盐性综合评价(D值)结果,对无盐和低盐各处理进行排序,筛选出对萌发期耐盐性最好的功能性肥料分别为T9和ST9。综上,T9处理的黄腐酸+聚谷氨酸+海藻寡糖复配方案为最佳。

Abstract:

This study aimed to investigate the effects of different functional fertilizers applied as seed soaking on cotton seed germination and salt-alkali tolerance, and to identify the optimal functional fertilizer for cotton cultivation in saline-alkali soils of Xinjiang. Two salt concentrations (0 and 50 mmol/L Na2SO4) were established, and four types of functional fertilizers, including peptide amino acids, fulvic acid, poly-γ-glutamic acid, and alginate oligosaccharides, along with seven combined formulations and a control group (CK), were tested. Seven traits, including germination potential, germination rate, germination index, fresh weight, dry weight, hypocotyl length, and root length, were measured. Correlation analysis, principal component analysis (PCA), and the membership function method were employed for comprehensive evaluation of salt tolerance. The results showed that: (1) compared with the non-salt treatments, the low-salt treatments increased average germination potential, germination rate, and germination index by 58.87%, 45.48%, and 43.08%, respectively. However, under low-salt conditions, fresh weight, hypocotyl length, and root length decreased by 39.00%, 57.22%, and 42.14%, respectively. (2) Compared with CK under non-salt conditions, treatment T9 (the combination of fulvic acid, poly-γ-glutamic acid, and alginate oligosaccharides) significantly increased germination potential, germination rate, and germination index (P<0.05), by 94.43%, 76.66%, and 84.75%, respectively. Treatment T7 significantly increased fresh weight, hypocotyl length, and root length (P<0.05), by 5.58%, 21.56%, and 4.46%, respectively, compared with CK. Under low-salt conditions, treatment ST8 significantly increased germination potential, germination rate, and germination index compared with SK (salt-stressed control), by 41.95%, 27.27%, and 29.09%, respectively. Treatment ST11 significantly increased fresh weight, hypocotyl length, and root length (P<0.05), by 6.99%, 42.74%, and 108.00%, respectively, compared with SK. (3) Correlation analysis indicated that germination rate was an important indicator for evaluating salt-alkali tolerance during germination. PCA transformed the seven traits into three independent comprehensive components, with a cumulative contribution rate of 81.668%. Based on the comprehensive salt-tolerance evaluation (D values), the treatments with the best salt tolerance during germination under non-salt and low-salt conditions were T9 and ST9, respectively. In conclusion, treatment T9, the combined formulation of fulvic acid, poly-γ-glutamic acid, and alginate oligosaccharides, was identified as the optimal formulation.
