| 摘 要： | 试验研究了控释肥对苹果幼树土壤有机质和pH值、叶片矿质元素和叶绿素含量以及新梢生长量的影响.结果表明,施肥降低了果园土壤的pH值和有机质含量,施用控释肥果园的pH值要高于普通复合肥,不同控释肥处理差异不明显；控释肥提高了叶片N、P和K的含量,控释肥CRF1处理的叶片N、P、K含量比普通复合肥处理分别高出7.6％、3.3％和11.4％；CRF1控释肥提高了苹果叶片中Ca、Mg、Cu和Mn的含量,降低了Fe和Zn的含量；控释肥处理明显提高了叶片叶绿素含量,不同控释肥处理之间差异不明显. |

| Abstract: | The effects of controlled release fertilizer(CRF) on young apple tree was researched in this paper,including soil organic matter,pH value,contents of mineral nutrients and chlorophyll in leaves and shoot length.The results showed that pH value and organic matter content of orchard soil were reduced by fertilization.The pH value of applying controlled release fertilizer was higher than that of applying common compound fertilizer,but there was not significant difference in different CRFs.The contents of N,P and K in leaves were increased by applying CRF,and those with CRF1 were 7.6%,3.3% and 11.4% higher than those with common compound fertilizer,respectively.The Ca,Mg,Cu and Zn contents in leaves with applying CRF1 were higher than those with applying the common compound fertilizer,whereas,the contents of Fe and Zn were reduced.The application of CRFs increased the chlorophyll content significantly,but there was no significant difference between different CRFs. |
