1、玉米品种地头会演讲稿篇一：玉米演讲稿普及一个小知识玉米原产美洲，哥伦布发现新大陆后才辗转流传至欧洲和中亚。史料记载明朝嘉靖年间，才由到麦加朝圣的回教徒带来中国，所以又有“西番麦”、“西天麦”之称。由于物以稀者为贵，它最初是皇帝的专利品，故有“御麦”之称。后来才在华北一带种植．但“种者也罕”(李时珍《本草纲目》卷二十三)。一直到清代，才推广到南方。玉米刚引进时，被视为珍品，只有鹊油蒸饼、熏鸭烧鸡一类的美味才配得上和它摆在一起，借以点缀。既有迷人的外观，又有高贵的身价，确实非“美人”莫属。再者，玉米既从华北传来，华北古称燕

2、赵，因此，以“燕美人”代称玉米，也就约定俗成，沿袭至今。玉米的功效与作用揭秘玉米的营养价值中医认为，玉米性平味甘，有开胃、健脾、除温、利尿等作用，主治腹泻、消化不良、水肿等症状。根据营养分析，玉米含有糖类、蛋白质、胡萝r素、黄体素、玉米黄质、磷、镁、钾、锌等，而这些都是女性不可缺少的美容营养素。篇二：种植大户演讲稿尊敬的各位领导：organizationsystemandworkingmode,theselectionofanumberofmunicipalstrengtheninggrouptobuildinnova
