摘要
以露地平作为对照,在4种不同覆膜播种方式下,研究不同覆膜播种方式对春玉米生长发育和产量的影响。结果表明,覆膜对玉米株高、叶面积指数、干物质积累均有促进作用,并且穗粒数、百粒质量均有所增加,故而籽粒产量明显提高,其中以垄作膜侧种植模式效果最优,比对照增产20.53%。综合分析认为,垄作膜侧种植模式具有促根壮苗、稳产增产作用,在严重缺水的华北旱作区推广应用前景广阔。
By four different methods of film mulching planting, with the no covering treatment as control, the effect of different methods of film mulching planting on spring maize growth and development, yield performance were studied. The results showed that the film mulching treatments could help improve the maize plant height, leaf area index and dry matter accumulation. The film mulching planting can increase grain yield mainly through their effects on grains per row and 100 grains weight. Among different mulching planting mode, the ridge tillage and film side seeding was the best, increasing by 20.53% compared with CK. By comprehensive analysis, it is concluded that the ridge tillage and film side seeding model had good effects for promoting root seedling and increasing yield and it has great prospects in area of North China with serious water shortage.
