| 摘 要： | 目的]探讨干旱气候下覆膜栽培对四川地区玉米产量的影响。方法]采用随机区组试验设计,研究覆膜与不覆膜（对照）2种栽培方法对川单428、正红311和川单418 3种玉米品种农艺性状和产量的影响。结果]在覆膜栽培条件下生长,3种玉米株高、穗位高、穗长、穗行数和行粒数等农艺性状均具较大优势;3种玉米覆膜栽培产量及千粒重均高于无覆膜栽培方法,且两者间差异性极显著。结论]在相同的生长条件下,与不覆膜相比,覆膜栽培技术生产的玉米农艺性状更好,产量更高。

| Abstract: | Objective] To study the effect of film mulching cultivation on the yield of corn under the drought conditions in Sichuan province.Method] The randomized block design experiments were carried out to study the effect of film mulching cultivation and no film mulching cultivation on the yield and agronomic properties of Chuandan 428,Zhenghong 311 and Chuandan 418 maize varieties under the drought conditions.Result] The results showed that plant height,fringe height,fringe length,rows per fringe and kernels per row of the three kinds of corn planted in the film mulching cultivation had greater advantage than that without film;yield and grain weight of the three kinds of corn planted in the film mulching cultivation were also greater than that of no flim mulching cultivation,with significant diference.Conclusion] Under the same growth conditions,the maize cultivated by flim mulching cultivation method got higher yield and better agronomic properties.than that by no film mulching cultivation. |
