摘要
This study aimed to clarify the effectsof mineral nutrient contents on fruit cracking so as to provide certain reference for further study on fruit cracking in apricot and basis for reasonable fertilization in the production. The 39-year-old apricot trees, with plant and row spacing of 3.0 m×4.0 m, were selected as the test materials, and the effects of contents of 7 kinds of mineral elements on the fruit cracking in apricot were analyzed. The results of variance analysis showed the intensity of correlation between mineral element content and apricot fruit cracking ranked as Ca＇s 〉 Zn＇s 〉 Mn＇s 〉 Fe＇s 〉 K＇s 〉 Mg＇s 〉 Cu＇s, The content of Ca was negatively correlated with cracking index, and the correlation ,coefficient was larger; the correlations between the contents of Zn and Mn and cracking index were weaker; and the correlations between the contents of Fe, K, Mg and Cu and cracking index were extremely weak. In conclusion, Ca deficiency is the main factor affecting fruit cracking in apricot.
分析杏裂果与矿质元素含量的相关性,为杏裂果机理的系统研究提供参考,同时为杏生产中合理配肥提供依据。以39年生树势一致的杏树为试材,株行距3.0 m×4.0 m。试验分析7种矿质元素对杏裂果的影响。方差分析结果显示,杏裂果与矿质元素含量的相关性大小排列为Ca>Zn>Mn>Fe>K>Mg>Cu。Ca元素含量与裂果指数呈现显著的负相关,相关系数较高;而Zn、Mn与裂果指数相关性较低;Fe、K、Mg、Cu元素与裂果指数相关性极低。Ca不足是影响杏裂果的主要因素。
