为了探索在山西早熟区无膜种植玉米的新模式及玉米育苗移栽的最佳移栽苗龄,采用完全随机区组设计大田试验,以覆膜直播为对照,分析了不同苗龄移栽对玉米生育进程、株高与产量及其构成因素的影响。结果表明,各苗龄移栽玉米的生育进程要略慢于对照。移栽具有降低株高的效应。虽然各苗龄移栽玉米的产量均低于对照,且随着移栽苗龄的增大呈现出差距加大的趋势,但通过移栽可以在该地区实现无膜种植玉米,其中二叶移栽的玉米产量与对照无显著差异,较覆膜直播(CK)仅减产9%。因此,在此试验条件下二叶期是山西早熟区玉米的最佳移栽苗龄。
In order to explore the new pattern of filmless planting corn in Shanxi precocious region and the optimal transplanting seedling age of maize seedling transplanting, the randomized block design was used to design the field experiment and the film-seeding direct seeding was taken as control. Effects of Maize Growth Process, Plant Height, Yield and Its Components. The results showed that the growth of maize transplanted at each age was slightly slower than the control. Transplanting has the effect of reducing plant height. Although the yield of corn at seedling age was lower than that of the control, and the gap increased with the increase of transplanting seedling age, but without transplanting, there could be no planting corn in the area, There was no significant difference between the yield of maize and the control, which was only 9% less than that of CK. Therefore, under this experimental conditions two-leaf stage is the best transplanting seedling age in Shanxi precocious maize.
