摘要: 目的】研究骏枣栽培模式下枣黑斑病发病程度的关系,不同病情级别及其与果实营养成分含量变化的相关性,为南疆红枣产业的转型升级和提质增效提供理论依据。【方法】以3种不同栽培模式的骏枣为研究对象,建立枣黑斑病分级标准,统计发病率和病情指数;分别采用蒽酮比色法、酸碱中和滴定法和分光光度计等方法测定枣果10种主要营养成分的含量,并应用 SPSS 软件进行一元回归分析。【结果】3种栽培模式下枣黑斑病的发病率和病情指数存在差异;枣果总酸含量与枣黑斑病危害级别呈正相关,而其余9种营养成分与枣黑斑病危害级别呈负相关。【结论】骏枣种植密度越大,枣黑斑病发生越重,且枣黑斑病不同病情级别均会不同程度降低枣果品质。

Abstract: Objective】 To study the relationship between jujube cultivation pattern and diseased level of jujube black spot, and correlation between the different diseased levels and changes of the fruit nutrient content and provide a theoretical basis for transformation and upgrading of the quality and effectiveness of jujube industry in Southern Xinjiang.【Method】Three kinds of different cultivation patterns of jun jujube were selected as the research object to establish the classification standard of jujube black spot and the incidence and diseased index were counted; The content of 10 kinds of main nutrients of jujube fruit were determinated using anthrone colorimetry, acid-base titration and spectrophotometry method etc., respectively, and a simple regression analysis was carried out using SPSS software.【Result】There are differences between the 3 cultivation modes of jujube black spot disease incidence and disease index and the content of total acid was positively correlated with the diseased grades of jujube black spot, and the rest was negatively related to 9 kinds of nutrients and jujube black spot disease level.【Conclusion】The bigger planting density of jujube, the more serious the diseased degree of jujube black, and different disease levels jujube black spot all could decrease the quality of jujube fruit.

Key words: planting mode; jujube black spot; disease index; fruit nutrient; regression analysis
