Abstract:
Field research was conducted to study the effects of SHK-6 application at R1 on soybean yield and yield components in different density using soybean cultivar “Jidou12”. The results indicated that SHK-6 significantly increased the yield， and the highest yield was observed when applying 100mg/L SHK-6 application at 40 plants/m2. In addition， the following parameters were increased by SHK-6 application： flower number (13.0%)， pod number (14.8%) seed number (10.9%)， pod weight (16.4%) and seed weight (12.3%) per plant， 100-seed weight (2.4%)， and seed/stem ratio (15.0%). On the other hand， SHK-6 application also increased the abscission number of flower and pod， but did not affect the percentage of the abscission. SHK-6 application decreased LAI， and increased low-layer canopy light interception and chlorophyll content. This could be responsible for yield increase.
