Abstract:
To study the agronomic characters and yield of different soybean varieties under monoculture and relay strip intercropping systems,three different shade tolerance varieties were planted.The results showed that compared with monoculture,the plant height and first pod height increased,the branch numbers and stem diameter decreased in relay-cropping.The variation range of soybean with good shade tolerance was smaller than the sensitive cultivar.The vertical distribution of yield ascended in relay-cropping system,soybean with better shade tolerance had the highest yield in 20-40 cm,and the highest ratio in 20-60 cm.Soybean sensitive to shade had the highest yield in 40-60 cm,and the highest ratio in above 40 cm.The horizontal distribution of yield centralized to the branches,and the yield in the branches of shade tolerant soybean was higher than the stem.In verse,the yield in the stem of shade sensitive soybean was higher than the branches and the ratio of stem yield was higher than monoculture.
