南京和苏南地区雨水很多,年降水量为1000～1200毫米,小麦生长期内降水往往在600毫米以上。在这种条件下,如何采取有效的栽培措施,看苗诊断,科学管理,处理好个体与群体协调生长的关系,解决穗多、穗大与壮稈不倒的矛盾,保证小麦高产稳产是当前小麦生产上急待解决的问题。小麦叶色和长相是一个信号系统,在人的感观上很易鉴别出是否缺肥和健康。从叶色的深浅可以反应出小麦植株体内的氮素水平和叶绿素含量的高低。多年试验表明,南京地区丰
Rainfall is abundant in Nanjing and southern Jiangsu Province, with an annual rainfall of 1000-1200 mm. Precipitation in the wheat growing season is often above 600 mm. Under such conditions, how to take effective cultivation measures to see the diagnosis of Miao, scientific management, to deal with the coordinated development of individuals and groups to solve the spikes, spike and strong stalks do not contradict the contradiction to ensure high and stable yield of wheat is the current Problems to be solved in wheat production. Wheat leaf color and appearance is a signal system, in the human senses is easy to identify whether the lack of fat and health. From the leaf color depth can reflect the level of nitrogen and chlorophyll content in wheat plants. Years of tests show that the abundance of Nanjing
