锌是作物生长不可缺少的微量元素之一。锌的生理功能主要是通过参与生长素的合成和某些酶系统的活动而影响作物的代谢过程。近年来,对微肥的研究日趋重视。本试验针对当地土壤含锌量较低的情况,于一九八四年在昌邑县进行,以探讨锌肥对小麦的增产效果及其对产量结构的影响,确定最佳锌肥施用方案,为大田生产提供依据。一、材料和方法试验地设在昌邑县流河乡,砂姜褐土,土壤含锌量0.3～000.5ppm(DTPA浸提),供试冬小麦品种为
Zinc is one of the essential trace elements for crop growth. The physiological function of zinc mainly affects the metabolic process of crops by participating in the synthesis of auxin and the activity of some enzyme systems. In recent years, more and more attention has been paid to the research of micronutrient fertilizer. In order to investigate the effect of Zn fertilizer on wheat yield increase and its effect on yield structure, this experiment aimed at the situation of low zinc content in local soil was carried out in Changyi County in 1984 to determine the best Zn fertilizer application plan Daejeon provide the basis for production. Materials and Methods The experiment was conducted in Liuhe Township, Changjiang County, where the Zn content of soil was 0.3 ~ 000.5ppm (DTPA leaching). The tested winter wheat varieties were
