中文摘要	采用大田试验对绿洲灌区玉米覆盖黑色、红色、蓝色与透明4种颜色地膜,对主要农艺性状进行相关性分析。结果表明:不同颜色地膜栽培的玉米相比透明地膜的经济产量增产率表现为:黑色膜减产9.22%,蓝色膜增产9.23%,红色膜增产2.29%。由于黑色地膜出苗率低导致玉米的生长密度降低,单株玉米的生境空间增大,出现双穗的比率增高,因而黑色地膜处理的单株产量较高。不同颜色地膜的各农艺性状表现为蓝色膜的株高、穗位、穗长、穗粒数均最高,黑色膜的千粒重最高,并且穗位低、茎粗高;在地膜影响下各玉米果穗性状对单株产量的相关系数均不显著,各性状对单株籽粒产量的相关系数依次为千粒重>穗行数>出籽率>行粒数>穗粗>穗粒数>穗长。
英文摘要	A field experiment was conducted to study the influences of black plastic film,blue plastic film,red plastic film and transparent plastic film mulching on the corn in Oasis irrigated area in order to explore the main agronomic traits of corn through the environmental correlation analysis.The economic output performed that the black film production reduced by 9.22%,blue film yield increased by 9.23%,and red film yield also increased by 2.29%relative to the transparent plastic film.The result of corn yield per plant by black film is the highest.With respect to the major agronomic traits,the result of various agronomic traits of corn by blue color film showed the highest value in terms of stem thickness,emergence rate,spike length and grains per ear.And the black film mulch showed the highest 1000-grain weight,the lowest emergence rate and the biggest spike height.The result indicated the correlation coefficient of environment for the traits to yield per plant was not significant,indicating the less effect of environmental factors on plant productivity and these seven traits.The environment correlation coefficients of each trait on grain yield per plant were showed the sequence:1000-grain weight>ear rows>seed production percentage>grains per row>spike thickness>grains per ear>spike length.
