不同外源肥对扁桃坐果率的影响及相关分析

The Influence and Correlation Analysis of Different Exogenous Fertilizer on the Almond's Fruit Setting

【目的】探明不同外源肥对扁桃坐果率的影响及不同肥料间的相关性。【方法】2009~2011连续3年在扁桃结果期园内萌芽前土施不同浓度梯度的N、P、K、B、Zn、Fe、Mn、Cu 8种肥料,统计扁桃坐果率和进行相关性分析。【结果】8种肥料均可显著或极显著提高扁桃的坐果率。【结论】比较3年坐果率的平均最大增加值,3种常量元素肥料对扁桃坐果率的影响顺序为N肥】K肥】P肥;5种微量元素肥料对扁桃坐果率的影响顺序为B肥】Cu肥】Zn肥】Fe肥】Mn肥;8种肥料对扁桃的坐果率的影响均表现为正相关的关系,其中K肥、B肥与N肥、P肥与K肥间呈极显著正相关的关系,P肥、K肥与Fe肥、Fe肥、Cu肥与Mn肥之间呈显著正相关的关系。

【Objective】In order to know the influence of different exogenous fertilizer on the almond's fruit setting and the correlation between the different fertilizers. 【Method】The soil was fertilized by eight kinds of different concentrations of fertilizers( N,P,K,B,Zn,Fe,Mn and Cu) in almond garden during the budding period from 2009 to 2011 in a row. The research was done based on the statistical data of fruit setting and correlation analysis. 【Result】The result showed that those exogenous fertilizers could significantly improve the almond's fruit setting. 【Conclusion】Compared with the fruit setting 's average maximum added value,we can see that the order of influence for three kinds of major element fertilizers was N > K > P,and also the order of the five trace element fertilizers was B > Cu > Zn > Fe > Mn; The eight kinds of fertilizers' influence was positive on the fruit setting,among which,the fertilizers of K and B had significant positive correlation with N; P had significant positive correlation with K. P and K were positively related with Fe and so were Fe and Cu with Mn.
