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。
In order to evaluate the comprehensive quality of Ziziphus jujuba Mill. And to determine the suitable application rate, the experiment was carried out on ’Ziziphushus jujube’ fruit with boron-zinc micro-fertilizer Single application and allocation of a total of 16 kinds of treatment, the fruit quality traits under the indicators of the data through the membership function transformation factor analysis and cluster analysis. The results show that: 1 The membership function method after the transformation of the data by factor analysis, extracted five eigenvalues> 1 common factor, the cumulative contribution rate of 80.559%, the factor score and the corresponding weights of the cumulative total score and proceed The results showed that proper application of boron and zinc fertilizers could improve the comprehensive quality of jujube fruits. The larger amount of boron and zinc micro-fertilizers applied alone or combined with jujube fruits did not significantly improve the comprehensive quality of jujube fruits and even reduced the comprehensive quality of jujube fruits. 2 Using cluster analysis to cluster the fruit quality data, we can know that when applying boron fertilizer alone, the effect of improving the comprehensive quality of jujube fruits by applying 22.5 kg / hm2 standard is significant, reducing or increasing the comprehensive quality of jujube fruits No significant effect on the comprehensive quality of Ziziphus jujuba collected when the single zinc fertilizer was applied at the standard of not more than 22.5 kg / hm2. When the boron-zinc micro-fertilizer was applied at the rate of 15 kg / hm2 or 22.5 kg / hm2 standard equivalent points acupoints on jujube fruit quality to enhance the role of the most significant. 3 Boron and zinc fertilizer with 15 kg / hm2 standard ratio of 1: 1 ratio of jujube fruit to enhance the overall quality of the most obvious improvement, and can minimize the application rate.
