Abstract:
The purpose of this study is to investigate the effect of different plant spacing on agronomic trait and yield of soybean in Ke-Bai region of Heilongjiang.The split plot design was used, the main treatment plant spacing factors included 6 levels(2, 3, 4, 5, 7 and 10cm), and the sub-treatment variety factor had 7 varieties belonged to 3 branches stem types, included infinite multi branches(Fengshou 6 and Huajiang 7734), infinite few branches(Fengshou 10 and Fengshou 27)and sub-infinite(Fengshou 24, Keshan 1 and Kefu 07-935) in the field cultivation condition in 2011 and 2012.The results showed that the effect of different spacing conditions on agronomic trait and yield of soybean were significant.With the increase of plant spacing, the plant height decreased gradually in the vegetative growth stage and first increased and then decreased in the later stage, the 5 nodes height and the height of the bottom pod were decreased, main stem node number, branch number, stem diameter, 1 seed pod,2 seed pod, 3 seed pod, 4 seed pod, shrunken pod, main stem pod and all pant pod number were increased,100-seed weight was disorder, pest grain incidence and disease grain incidence were reduced, the protein content was reduced, the fat content was increased, the yield starting was increased and then decreased gradually, the suitable plant spacing of branched material was 7 cm, the suitable plant spacing of main stem type material was 5 cm.
