锌是微量元素之一,近十年来,水稻土中普遍缺锌。土壤缺锌可能是由于原有锌和施用锌二者与土壤有机相和无机相发生反应而影响锌的有效性所致。土壤中各种型态的锌,其有效性因型态不同而变化。这些型态的锌约制着活性土壤成分和土壤溶液中锌的分布状况,这是研究锌的土壤化学基础。 本研究的目的是:(1)测定土壤原有锌与施用锌的分布及其与活性土壤组成的联系性;(2)
Zinc is one of the trace elements, the past decade, paddy soil generally zinc deficiency. Zinc deficiency in the soil may be due to the effectiveness of zinc affected by the reaction of the original zinc and the applied zinc with the organic and inorganic phases in the soil. Various types of soil zinc, its effectiveness varies with the type of change. These types of zinc control of active soil composition and soil solution of zinc distribution, which is to study the soil chemical basis of zinc. The purpose of this study was to: (1) determine the distribution of native and applied zinc in soil and their association with active soil composition; (2)
