控释肥对苹果幼树生长发育的影响
Effects of Controlled Release Fertilizer on Growth and Development of Young Apple Tree
摘要
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.关键词
