摘    要:以晚熟稀植型品种丹玉39和中晚熟密植型品种郑单958为试材,通过5年的定点栽培试验,对玉米株高在年际间的稳定性及其与产量的关系进行研究。结果表明,在不同年份环境条件下,玉米株高存在明显差异;株高形成期降水量是影响株高变化的根本原因,两者间呈显著的正相关关系;积温和日照时数各年均能够满足玉米株高生长发育需求,株高与两者无相关关系;在不同年份环境条件下玉米株高对密度的响应,因每年降水量多少及其分布而不同,在水分供应充足的年份,高秆稀植型品种随着密度加大而株高增加的趋势明显,而耐密植品种的反应相对较稳定。在株高与产量的关系上,不同耐密性品种之间也有所不同。

关 键 词:玉米  株高  不同年份  气象因子

Abstract:The stability of the maize plant height and the relationship between plant height and yield were studied through five years of designated cultivation test by using late-maturing and sparse-planting variety Danyu39 and medium-late-maturing and close-plant variety Zhengdan958 as experimental materials.The results showed that there were great differences among plant height under the environment of different years;precipitation in the formative period of plant height was the root cause to affect the changes of plant height,and there was a significant positive correlation between them.Accumulated temperature and sunshine duration each annual could satisfy the needs of the plant height growth and development,but plant height had no correlation with them.Because of the differences of precipitation and distribution,the respond of plant height to density in different years is diverse.Under good condition of water supply,the plant height of tall and big ear variety,with increasing of density,had an increasing trend,however close-plant variety had a relatively stable reaction.The relationship between plant height and yield of density-tolerant property varieties was different.
Keywords:Maize  Plant height  Different years  Meteorological factor
