摘要
为了进一步提高旱地玉米的产量和效益,针对燕山丘陵旱作区降水量少、季节间降水不均、作物产量低等问题,研究了4种不同覆膜栽培方式对旱地玉米生长发育和产量的影响。结果表明,全覆膜垄作使玉米提早成熟10-14d,株高、叶面积指数、干物质积累量始终高于其他覆膜方式,同时结实率和穗重增加;2013、2014年分别较对照增产27.15%、51.22%,显著提高了水分利用效率和产量。
In order to improve the yield and benefit of dryland maize,aimed at the problems of limited and unevenly distributed rainfall and low yield farmland in the dry-farming areas in Yanshan hilly Inner Mongolia, study on 4 kinds of different film mulching treatment field test analysis of effects of different treatments on the growth and yield of dryland maize.The results showed that the mode of whole plastic-film mulching could advance maturity time 10 -14 day,increase plant height,leaf area index and dry matter accumu-lation,raise seed setting rate and panicle weight, In 2013and2014,the yield increased by 27.15%,51.22% respectively,raise yield and water use efficiency of maize significantly.
