春玉米不同品种及种植方式对植株生长的影响

Effects of Different Spring Maize Varieties and Their Cropping Patterns on Plant Growth

在多熟制生产条件下 ,本试验以“掖单 1 3”、“苏玉 9号”、“农大 31 38” 3个玉米品种为试材 ,分别设置了春玉米覆膜移栽、露地移栽和地膜直播 3种种植方式 ,研究了不同品种不同种植方式的生育进程 ,根系生长、株高增长及叶片生长等方面的生长特点 ,植株性状的差异与穗部性状以及产量表现。

Three maize varieties including Yedan 13, Suyu 9 and Nongda 3138 are selected as study materials, compared with spring maize transplanted with plastic film mulching, outdoor transplantation and plastic film covered after sowing three cropping patterns under multi cropping to research the characteristics of different varieties and different cropping patterns, including root growth, plant height increment and leaf growth, the difference of plant traits and ear traits and the yield results. All these could provide theoretical basis to study high yield spring maize by high efficient technical ways and its multi cropping systems
