锌是作物正常生长发育所必须的微量元素之一。它在作物体内虽然含量很低(仅十万分之几至百万分之几),但对作物体内的代谢、氧化还原过程,细胞的呼吸作用,叶绿素和生长素的形成,都起着极为重要的促进作用。作物缺锌,就会造成多种生理病害,导致其经济产量和品质的降低。为了探索锌肥在玉屏县的施用效果,在上级业务部门的支持下,我县、社(镇)农技站,于今年进行了水稻施锌的试验、示范。
Zinc is one of the trace elements necessary for the normal growth and development of crops. Although its content in the crop is low (only a few parts per million to a few parts per million), it plays a very important role in crop metabolism, redox processes, cellular respiration, chlorophyll and auxin formation Important to promote the role. Zinc deficient crops, it will cause a variety of physiological diseases, resulting in reduced economic output and quality. In order to explore the application of zinc fertilizer in Yuping County, with the support of the superior business department, our county, community (town) agricultural station, this year conducted a test of rice zinc, demonstration.
