玉米具有植株高大,需光热量多,占用营养面积较大的特点。田间试验小区占地面积大,收获计产的果穗体积大,数量多。以往试验计产是将每一小区全部果穗晒干脱粒后计算,因而每项试验小区数量多,按小区摊晒果穗,需用较大的晒场。同时,在我国南方玉米产区,收获季节多遇霄暴雨,摊硒
Corn plants with tall, light and more calories, occupy a larger area of nutrition characteristics. Field test plot covers an area of ?? large, large-scale production of ear harvest, the number of large. In the past, test production was calculated after all the ears of each plot were dried and threshed. Therefore, the number of test plots in each plot was large. At the same time, corn production areas in southern China, harvest season mostly heavy rain, share of selenium

新中国成立70年来,阳泉市平定县的农机化水平有了大幅提高,玉米、薯类、谷子等主要农作物耕、种、收等主要环节机械化技术和装备已基本成熟并得到大面积推广。对于以山地和丘陵为主的平定县来说,这样的成绩是来之不易的。 截止到2018年,平定县农机总动力达到11万千瓦,农业机械在农、林、牧、副、加工等诸多领域发挥了不可替代的作用。 平定县农机化的快速发展有力地促进了平定县的经济发展,多次受到上级的表彰和
