玉米不同密度下苗期分蘖处理对农艺性状和产量的影响

试验选取当前主栽的玉米杂交种先玉335、丹玉801和丹玉336为材料,采用裂区试验设计,研究不同密度下分蘖处理对品种根系、株高、穗位和产量的影响。结果表明:随种植密度增加分蘖数量逐渐减少,苗期分蘖对根系的生长具有一定促进作用,掰除分蘖能够提升玉米植株和穗位高度,特别是对玉米苗期株高提升明显,同密度下是否掰除分蘖产量差异不显著。最终认为苗期保留分蘖对玉米生长发育和产量影响不大。 英文摘要: Three hybrids Xianyu335, Danyu801 and Danyu336 that utilized widely on maize production were chose as the materials in the study. Studying the impaction on root, plant height, ear height and yield through tillers treatment with different density were made by split plot design.
