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.展开更多
