摘要
在铜川黄土高原区研究2种硅肥(有机、无机)在苹果树上的施用效果及其对中微量元素吸收的影响。结果表明,施用硅肥可以提高苹果树叶片和果皮中硅的含量,施用有机硅肥比无机硅肥叶片和果皮中硅含量平均提高8.1%和6.67%;同时,施用硅肥促进苹果叶片中锌、钙的吸收;施用有机硅肥促进果肉中铁、锌含量增加,特别是有利于铁、锌向果肉中转移。无论是无机硅肥和无机中微量元素配合、还是有机硅肥和有机中微量元素配合,均能提高苹果产量,在硅肥低用量下,有机硅肥相对增产更大。
This paper studied the effects of two kinds of silicon fertilizer （organic and inorganic） appli the apple yield and the absorption of other micro-elements in Tongchuan region of Loess The results showed that applying silicon fertilizer could improve the silicon content in leaves and pericarp. The silicon content in apple leaves was more than 8.1% higher in average with organic silicon fertilizer, and in peels was more than 6.67 % higher. Application of silicon fertilizer increased the zinc and calcium content in apple leaf. Application of organic silicon fertilizer increased the iron and zinc content in flesh and promoted yield was improved by either inorganic tilizer, or organic silicon fertilizer plus organic silicon fertilizer, organic fruit yield when silicon fertilizer Sl the transport of iron and zinc from the leaves to flesh. Apple silicon fertilizer plus inorganic medium and micro-element fer- organic medium and micro-element fertilizer. Comparing to in- icon fertilizer had a relatively higher potential to enhance apple was applied in a low level.
