Morphology and Yield of Crops in Different Rows Under Soybean and Maize Strip Compound Planting Systems
摘要
Abstract
To quantify the changes in plant morphology and yield of soybean and maize in different field configurations and provide a basis for selecting configurations,this experiment set up five intercropping treatments,namely 2S2M,4S2M,4S3M,6S2M,and 6S3M(numbers re-present rows,S represents soybeans,and M represents maize).Using monoculture soybeans(SS)and monoculture maize(SM)as controls,the plant morphology,yield of each row of crops,land equivalent ratio and economic benefits under intercropping treatments were analyzed.Results showed that there were differences in soybean yield among different rows of soybean maize composite planting modes with different con-figurations.Compared with monoculture,the configuration of 6 rows of soybeans resulted in a 53.20%decreased in yield for soybean row 1(the outermost row),a 42.73%decrease in yield for soybean row 2(the second row),and a 29.87%decreased in yield for soybean middle row.In the configuration of four rows of soybeans,the side row of soybeans decreased by 56.18%compared to monoculture,and the middle row of soybeans decreased by 53.20%compared to monoculture.Soybeans yields of the configuration of 6 rows were 1.20 times higher than the configuration of 4 rows of soybeans.There were differences in maize yield among different rows of soybean and maize compound planting modes with different configurations.The configuration of 2 rows of maize had marginal effects on each row of maize,so there was no significant difference in maize yield between the configuration of 2 rows of maize and monoculture(except for 6S2M),while the configuration of 3 rows of maize had significantly lower maize yield per row than monoculture.Although 6S2M was beneficial for soybean growth and had the highest soy-bean yield,the small spacing between maize plants was not conducive to maize yield;the configuration of intercropping two rows of soybeans with two rows of maize had a side row effect and the highest yield,but the number of soybean rows was small,resulting in significantly lower soybean yield than other configurations.From the perspective of land equivalent ratio and economic benefits,the configuration of intercropping 4 rows of soybeans and 2 rows of maize had no significant difference compared to monoculture,and the soybean yield was higher,making it a recommended configuration.关键词
