摘要
为筛选出玉米与大豆间作的高产栽培模式,进行了玉米大豆不同行比(1∶1,1∶2,1∶3,1∶4,2∶1,2∶2,2∶3,2∶4,3∶1,3∶2,3∶3,3∶4)间作对黔豆7号鼓粒期产量性状的影响试验。结果表明:黔豆7号的单株荚数、单株鲜荚重、单株鲜重、单株干重、单株鲜粒重和理论产量随玉米行数增加呈降低趋势,随大豆行数增加呈增加趋势;不同行比黔豆7号的百粒重差异不大。除百粒重外,玉米、大豆行数对其他产量性状的影响显著或极显著。在玉米大豆行比为1∶3时黔豆7号的产量及产量性状表现最优,单产可达9 418.80kg/hm^2。
In order to identify the high yield cultivation model in intercropping system of maize and soybean,effects of different rows ratio of maize and soybean(1∶2,1∶3,1∶4,2∶1,2∶2,2∶3∶∶4∶2∶1∶∶3∶∶2∶3∶1∶1∶3∶3∶4∶3)in intercropping system on the yield traits of soybean during seed filling period were tested.Results:Pod number per plant,fresh pods weight per plant,fresh weight per plant,dry weight per plant,fresh grain weight per plant and theoretical yield decreased with the increase of the rows number of maize and increased with the rows number of soybean.And the difference of 100-grain weight was not significant in different row ratio between maize and soybean.The changes of pods number per plant,fresh pods weight per plant,fresh weight per plant,dry weight per plant,fresh grain weight per plant and theoretical yield were significant or extremely significant.In addition to 100-grain weight,the rows number of maize had a significant or extremely significant effect on the other yield traits,and the rows number of soybean had a significant or extremely significant effect on other traits except the traits of 100-grain weight and dry weight per plant.The highest yield of soybean was 9 418.80kg/hm^2 when the rows ratio of maize and soybean was 1∶3.
