Abstract
The effects of different maize sowing date and density on the stem and leaf morphological characters and yield of soybean in wheat /maize /soybean relay-cropping system were studied. The results showed that,with early sowing of maize,the maize yield was promoted,the harvest forward,the co-growth period with soybean was shortened,this guaranteed soybean's suitable plant height,bigger stem diameter,ideal LAI and SLW,so soybean yield was also increased. The effects of different maize density on the stem and leaf of soybean mainly was significant before the maize harvest,but soybean yield under high maize density was significantly lower than that under middle and low maize density,and the highest maize yield was under middle density. Based on considering soybean and maize comprehensive values,the optimum combination of this experiment was sowed at March 21 and planting density was 5. 25 × 104plant·hm- 2.
