摘要: 为了对硼锌微肥单施及配施下枣(Ziziphus jujuba Mill.)果实综合品质进行评价,并确定适宜的施用量,以‘金丝4号’枣果实为试材,通过硼锌微肥单施及配施共16种处理,将各处理下果实品质性状指标数据通过隶属函数转化后进行因子分析与聚类分析。结果表明:①隶属函数法转化后的数据经因子分析后,抽取出5个特征根>1的公因子,累计贡献率为80.559%,将因子得分与相应权重之积累加得到综合分值并进行排序可知,适当施用硼锌微肥可以提高枣果实的综合品质,硼锌微肥单施或者配施的量较大对枣果实综合品质的提高作用不显著甚至会降低枣果实综合品质。②利用聚类分析将果实品质数据进行聚类可知,当硼肥单施时,以22.5 kg/hm2标准按穴均施对枣果实综合品质的提高作用显著,减少或者增加用量对枣果实综合品质没有明显影响; 当锌肥单施时,以不大于22.5 kg/hm2标准按穴均施对枣果实综合品质的提高作用显著; 硼锌微肥配施时,以15 kg/hm2或者22.5 kg/hm2标准等量按穴均施对枣果实品质的提高作用最为显著。③硼锌微肥以15 kg/hm2标准按1:1比例配施对枣果实综合品质的提高作用最明显,并可以最大限度地减少施用量。

Abstract: In order to establish an applicable synthetical evaluation method of fruit quality of Ziziphus jujuba Mill. under the application of single and different combinations of boron and zinc microelement fertilizer, and to determine appropriate proportion and amount of the boron and zinc microelement fertilizer,fruits of Z. jujuba Mill.cv.Jinsi 4 were treated with 16 different combinations of boron and zinc microelement fertilizer in this experiment. The data matrix in this study was converted by the method of subordinate function for factor and duster analyses. Results showed that:①Five factors(eigenvalue>1)were extracted from the converted data matrix. Their cumulative contribution approximated to 80.559%. The synthetical score was the accumulation of the product of the score of each factor multiplied by the corresponding weight value of each factor. Based on the sort of synthetical score, it was proposed that appropriate application of boron, zinc micronutrient fertilizer could improve the comprehensive fruit quality, but the greater amount of the boron, zinc microelement fertilizer could not improve the comprehensive quality of fruit.②According to the result of cluster analysis on fruit quality data, when boron fertilizer with 22.5 kg/hm2 was applied individually, the improvement of fruit quality was the most effective and reducing or increasing application amount had no significant effect on fruit quality. When zinc fertilizer with no more than 22.5 kg/hm2 was applied alone, the improvement of fruit quality was the most effective. When microelement fertilizers combinated with 15 kg/hm2 of boron plus zinc in equal amount or 22.5 kg/hm2 of boron plus zinc in equal amount were applied individually, the effect of microelement fertilizer on improvement of fruit quality was the most significant.③When micronutrient fertilizer combinated with 15 kg/hm2 of boron plus zinc in ratio of 1:1 was applied, the improvement of fruit quality was the most effective, and the amount of boron and zinc micronutrient fertilizer was minimized.
