| 摘 要： | 以、7 a生曙光油桃为材料,在固定氮、磷比例基础上,通过改变钾肥用量,分析钾素营养对油桃采果期树体养分的影响.结果表明:油桃采果期枝、叶中可溶性糖和可溶性淀粉含量随钾用量增加而增加,且都显著高于对照.施钾有利于各器官中K的积累,且随钾用量增加,各器官中K含量相应增加.钾用量与油桃叶片和果实中N含量存在极显著正相关,与枝条中N含量、果实中Ca含量存在极显著负相关,与枝条中Ca、Mg含量存在显著负相关. |

| Abstract: | The 7-year-old Shuguang nectarine trees were taken as the materials and studied in this experiment.In the study,the effects of potassium nutrition on tree nutrient in fruit picking period of nectarine were analyzed by changing the dosage of potassium on the basis of fixed proportion of nitrogen and phosphorus.The results showed that:In the fruit picking period,the soluble sugar and soluble starch content in leaves and shoots increased with the increasing of the potassium dosage,and were significantly higher... |
