Effect of nitrogen on vertical distribution of canopy nitrogen and chlorophyll relative value (SPAD value) of summer maize in sub-humid areas

open access: yes, 2009
以半湿润地区土垫旱耕人为土为供试土壤,采用田间试验,研究了不同施氮水平下夏玉米(Zeamays L.)拔节期、灌浆期和成熟期3个生育期冠层叶片氮素、叶绿素相对值(SPAD值)的垂直分布规律及其差异;同时对各层叶片含氮量、SPAD值与施氮量进行相关分析。结果表明,在各生育期不同叶层叶片含氮量按上、中、下层顺序呈明显递减规律,从全生育期不同施氮处理看,上层比中层增加6.64%,中层比下层增加5.18%。随施氮量增加,中上层叶片含氮量差异增大,中下层叶片含氮量差异减小 ...

Effect of fertigation depth on dry matter partition and water use efficiency of corn

open access: yes, 2003
用土柱管栽试验方法研究了不同灌溉施肥深度对夏玉米生长发育、地上地下部分同化物分配、产量和水分利用效率的影响。试验结果表明:土表下灌施抑制了玉米生育早期的地上部分生长,使根系向土壤中下层的分布加强,从而保证了作物中后期对水分养分的吸收利用,提高了水分利用效率。在本试验条件下 ...

A Study on WUE and Pn Diurnal Change Features and Its Mechanism in Crops Under Different Water Conditions

open access: yes, 1999
通过对供水和干旱下春小麦(TriticumaestivumL.)和夏玉米(ZeamaysL.)生理生态适应研究表明:作物水分利用效率(WUE)、光合速率(Pn)日变化受干旱缺水影响明显,干湿处理间其差别最明显时段为下午(12:00~16:00);缺水时作物Pn在午前段以气孔限制为主,午后段则以非气孔限制为主;缺水对WUE日变化影响作用与叶水势,以及大气环境因素 ...
