| 摘 要： | 以金山27为试验材料,采用田间试验的方法,研究了不同栽培模式下春玉米氮吸收与利用的特性.结果表明,各生育时期单位面积氮吸收量和吸收速率均以再高产栽培模式＞高产栽培模式＞农户栽培模式;吐丝后氮的吸收量占生育期总吸收量的比例以再高产栽培模式＞高产栽培模式＞农户栽培模式;成熟期籽粒中氮的分配比例再高产栽培模式与高产栽培模式差异不显著,但二者均显著高于农户模式;氮收获指数为再高产栽培模式＞高产栽培模式＞农户栽培模式,氮素养分利用效率及氮肥偏生产力均为高产栽培模式＞农户栽培模式＞再高产栽培模式.

| Abstract: | Characteristics of nitrogen absorption and utilization of spring maize were studied under different cultivation patterns by field test methods using Golden Hill 27 as experimental materials.The results showed as follows.Nitrogen absorption amounts and absorption rates of unit area in each growth and development al stage were all further-high-yield cultivation pattern>high-yield cultivation pattern>farmer cultivation pattern;proportion of amount of nitrogen absorption after spinning accounting for total abso... |
