摘　　要：为提高苜蓿与冬小麦间作的产量和品质,通过研究苜蓿-冬小麦间作模式下苜蓿和冬小麦叶片的SPAD值和产量的变化,寻求冬小麦主产区适宜的苜蓿-冬小麦种植模式。设置苜蓿∶冬小麦为1m∶1m(MD)和1m∶2m(M2D)的间作模式,同时以单播冬小麦(CK-X)和单播苜蓿(CK-M)作对照,测定苜蓿、冬小麦叶片的SPAD值、株高和产量变化,计算并对比分析不同种植模式SPAD值与产量的变化规律。结果表明:不同种植处理苜蓿叶片的SPAD值为MD>M2D>CK-M,株高为CK-M>M2D>MD;冬小麦叶片的SPAD值为M2D>MD>CK-X,株高为CK-X>M2D>MD;MD、M2D与CK-M和CK-X相比,苜蓿产量分别减少15.16%和9.36%,冬小麦产量减少41.04%和29.72%。M2D种植模式下,苜蓿、冬小麦叶片SPAD值与产量呈线性正相关关系,且冬小麦穗粒数、千粒重与单播冬小麦差异显著。In order to improve the yield and quality of alfalfa and winter wheat,the changes of SPAD values and yield of alfalfa and winter wheat leaves in alfalfa-winter wheat strip intercropping were studied to find a suitable alfalfa-winter wheat strip planting mode in the main winter wheat producing areas.The strip intercropping model of alfalfa:winter wheat was set up in the experiment,the models are 1 m∶1 m(MD)and 1 m∶2 m(M2D).Simultaneously,single winter wheat(CK-X)and single alfalfa(CK-M)were used as a contrast,the changes of SPAD values,plant height and yield of alfalfa and winter wheat were measured,and the change rule of SPAD value and yield of different planting patterns were calculated and compared.The results showed that the SPAD values of alfalfa leaves under different planting treatments were MD>M2D>CK-M,and the plant height was CK-M>M2D>MD.The SPAD value of winter wheat leaves was M2D>MD>CK-X,and the plant height was CK-X>M2D>MD.MD,M2D reduced alfalfa yield by 15.16%and 9.36%,and winter wheat yield by 41.04%and 29.72%respectively,compared with CK-M and CK-X.The SPAD values of alfalfa and winter wheat leaves were positively correlated with yield under the strip intercropping M2D planting mode,and there were significant differences between the spike grain number and 1000-grain weight of winter wheat and single-seeding winter wheat.
