玉米是需肥较多的作物,了解玉米不同生育时期的营养生理特性和各种养分相关间的作用,是玉米合理施肥的基础。正确掌握玉米所需要的养分种类和数量,及时地施用适量的所需养分,才能获得玉米高产。现将看苗施肥方法介绍如下:1 氮缺乏症。玉米对氮的需要量比其它任何元素都多。早期缺氮不易发现,只有幼苗呈浅黄色时,才能证实,这时采用侧施肥的办法解决,也可根外追肥,喷1％～5％的尿素溶液。当玉米长到膝盖高时,生长 Maize is a fertilizer that requires more fertilizer. Understanding the nutritional and physiological characteristics of maize at different growth stages and the role of various nutrient-related maize is the basis for proper fertilization of corn. Correct grasp of the types and amounts of nutrients needed by corn, the timely application of the necessary nutrients in order to obtain high yield of corn. Now see seedling fertilizer methods are described below: 1 nitrogen deficiency. Corn needs more nitrogen than any other element. Early nitrogen deficiency is not easy to find, only the seedling was pale yellow, to confirm, then use the side fertilization solution, but also the top dressing, spraying 1% to 5% urea solution. Grow when corn grows to knee high
