摘要: 为了明确寒旱区地膜覆盖与育苗移栽对促进中晚熟玉米生长及增加产量作用的相对重要性,采用完全随机区组设计大田试验,分析比较了这两种栽培方式对玉米生育进程、株高变化与穗位高及各产量构成因素的影响。结果表明,地膜覆盖直播玉米的生长发育进程明显地早于育苗移栽玉米。地膜覆盖较同期直播(5月2日)产量增加32.0%;育苗移栽膜地产量较直播提高34.7%。增产的原因主要是百粒重的显著增加。各处理相比,移栽可使株高和穗位高降低,覆膜(包括移栽膜地)则能够提高产量和降低秃尖的长度。综合投入产出比较,覆膜种植是目前山西寒旱区春玉米较好的种植方式之一。

Abstract: In order to understand the relative importance of plastic film mulching and seedling and transplanting on the improvement of growth and yield of middle-late corn in cold and arid region, a field experiment with completely randomized block design was employed to analyze and compare the effects of different cropping patterns on the maize growth process, plant height variation, ear height and yield component characters. The results showed that the growth of maize covered with plastic film was significantly earlier than seedling and transplanting maize. Yield of film-mulching maize increased by 32.0% compared to direct sowing in the same period (May 2nd); while the maize yield of seedlings and transplanting to farmland covered with film was 34.7% higher than direct sowing maize. The reason of mulching treatment increasing maize yield was mainly due to the increase of weight per hundred kernels. Compared with each treatment, transplanting made plant height and ear height low, but film mulching (including transplanting to farmland covered with film) could improve yield and decrease the length of bare tips. In overall consideration of input and output, film covering is one of good planting ways of spring maize in cold and arid regions of Shanxi Province.
