玉豆轮作下不同玉米秸秆还田方式对玉米生长特性、产量及其构成的影响

Effects of Different Ways of Returning Corn Stalks to the Field on Corn Growth Characteristics,Yield and Its Composition under Maize Bean Rotation

将玉米秸秆还田与玉米-大豆轮作相结合,研究玉豆轮作下不同玉米秸秆还田方式对玉米生长特性、产量及其构成的影响。结果表明,玉-豆轮作下,秸秆还田可有效地促进玉米的生长发育,提高玉米产量。其中玉米秸秆秋季翻埋还田效果最佳,玉米植株的株高、茎粗、叶面积及产量均得以有效提高。不同玉米秸秆应用方式处理的玉米产量较玉米连作(CK1)增加11.4%,较玉米大豆轮作(CK2)增加9.2%。

In this paper,the corn stalk returning to the field is combined with the corn-soybean rotation to study the effects of different ways of returning corn stalks to the field on the growth,yield and composition of corn under the maize bean rotation.The research results show that under the maize-bean rotation,returning straw to the field can ef⁃fectively promote the growth and development of maize and increase the yield of maize.Among them,the effect of burying corn stalks in the field in autumn is the best,the plant height,stem thickness,leaf area and corn yield of corn plants.can be effectively improved.Compared with corn continuous cropping(CK1),the corn yield of different corn straw returning methods increased by 11.4%,and increased by 9.2%compared with corn soybean rotation(CK2).
