锌是作物生长发育必需的微量营养元素,在作物体内主要参与生长素的合成和某些酶系统的活动。玉米是对锌元素最敏感的作物之一,缺锌影响碳水化合物的合成和新陈代谢作用,引起“花白叶病”等病症,严重影响产量和品质。 1986年我们和泸州天然气化工厂科研设计所联合组织,统一设计方案,分别在纳溪和安岳两县玉米上,同时进行两种锌肥的肥效试验。试验结果,在施用等量氮肥基础上,凡增施锌肥的产量均极显著高于仅施氮肥的处理。
Zinc is an essential micronutrient for crop growth and development. It is mainly involved in the synthesis of auxin and the activity of certain enzyme systems in crops. Corn is one of the most sensitive zinc crops, zinc deficiency affect the carbohydrate synthesis and metabolism, causing “white leaf disease” and other diseases, seriously affecting the yield and quality. In 1986 we and the Luzhou Natural Gas Chemical Plant research and design institute jointly organized and unified design program, respectively, in the two counties of Naxi and Anyue corn, at the same time two kinds of zinc fertilizer efficiency test. The results showed that on the basis of applying the same amount of nitrogen fertilizer, the yield of zinc fertilizer was significantly higher than that of nitrogen fertilizer only.
