杏裂果与矿质元素含量的相关性研究

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CaZnMnFeKMgCu。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。

Correlation of Fruit Cracking and Mineral Nutrient Content in Apricot

This paper aims to clarify the effects of mineral nutrient contents on fruit cracking in order to provide certain references for further study on fruit cracking in apricot and basis for reasonable fertilization in the production. 39 years old apricot trees were used in the test. The row and plant spacing of apricot trees was 3.0 m×4.0 m. The effects of 7 mineral elements on fruit cracking in apricot were analyzed. Correlation between fruit cracking and mineral nutrient content in apricot was in an order as Ca>Zn>Mn>Fe>K>Mg>Cu. There was a negative correlation between Ca and fruit cracking, and the correlation coefficient was relatively high, Zn and Mn had a low correlation with fruit cracking, but there was no obvious correlation between Fe, K, Mg, Cu and fruit cracking. This study showed that the main factor affecting fruit cracking was calcium deficiency.
