摘要: 为了探索在山西早熟区无膜种植玉米的新模式及明确该地区玉米育苗移栽的适宜移栽时期,采用完全随机区组设计大田试验,以覆膜直播为对照,分析比较了不同时期露地移栽对玉米生育进程、株高、成熟期棒三叶叶面积与产量及其构成因素的影响。结果表明:各时期移栽玉米的生育进程均慢于对照。移栽具有降低株高与减小成熟期棒三叶叶面积的效应。在本试验条件下5月1日移栽玉米产量与对照无显著差异,较覆膜直播(CK)仅减少了7%。在早熟地区采用育苗移栽方法无膜种植玉米时必须注意当地晚霜对玉米幼苗的伤害,可以认为在该地区适宜的移栽时期应当是在当地晚霜之后抓紧时间尽早移栽。

Abstract: In order to explore the new mode of film-free corn cultivation in early mature area of Shanxi Province and identify the appropriate transplanting period of corn seedling in this area, a field experiment with completely randomized block design was conducted to analyze and compare the effect of different transplanting periods of corn seedling on the growth process, plant height, area of three ear leaves of mature corn, yield and its component factors, film direct seeding was used as CK. The results showed that the growth processes of corn seedlings transplanted in different periods were slower than that of CK. Transplanting mode could reduce plant height and the area of three ear leaves of mature corn. There was no significant difference between the yield of corn transplanted on May 1st and CK, which reduced by 7% compared to that of CK. Damages to the corn seedlings caused by local late frost must be noticed when corn seedlings were transplanted without film in early mature area, transplanting the seedlings just after the late frost could be considered as an appropriate way in this area.
