不同施锌方法对小麦含锌量及产量影响的研究

Impacts of Appling Zinc with Different Methods on Zinc Content and Yield of Wheat

锌是植物体内多种酶的组成成份和活化剂。缺锌影响植物生长和人体健康。在缺锌土壤上施锌肥虽已推广,但用何种方法最好,众说不一。我国有大面积耕地缺锌,研究锌肥及其施用方法是很重要的。本项研究在国内外近期研究的基础上,在缺锌土壤上使用不同的方法施锌肥,通过对小麦的叶绿素含量、干物重、含氮量、含锌量、17种氨基酸的含量及产量的分析测定,证明土施是最简单、成本最低、效果最好的方法。

Zinc is an element and activator contained in Varied enzymes in plants. Zinc-deficiency greatly affects the growth of crops and health of humanbeing. To apply zinc with different methods to zinc-deficit soils has been popularized, but the opinions vary greatly on which method is the best. In China there are many cultivated land being short of zinc, so it is highly important to study the methods and results of appling zinc to soil. Experiments of appling zinc by different methods to zinc insufficient soils were conducted. It was shown that the sim-ple method of appling zinc to .soil had the best results based on analysis of the contents of chlorophyll, nitrogen and zinc, biomass, contents of 17 kinds of amino acids as well as the output of wheat. And the cost of this simple method was also very low.
