Abstract:
This study was conducted to evaluate the yield structure as well as the yield characteristics of narrow row and dense seeded semi-dwarf soybean cultivar.Our objective was to present technical references for the research and application of super-high yield soybean.Field experiments were conducted with three soybean cultivars and three cultivation patterns and three treatments，they were B45(semi-dwarf variety He 98-1667 planted with row space of 45 cm and density of 41.5×104plantsha-1)，G70(tall stalk variety Longxuan 1 planted with row space of 70 cm and density of 18.8×104plantsha-1) and Z45(middle short stalk variety Kenfeng 16 planted with row space of 45 cm and density of 30.5×104plantsha-1).In the case of narrow row，dense seeded，rich fertilizer and irrigation，the semi-dwarf cultivar B45 was featured with low bottom pod and strong stalk.Though the pods and seeds of the single plant of B45 were significantly less than those of the other two cultivars，relatively high number of pods and seeds can be got due to the dense seeded.The average pods and seeds were 145.1 and 411.7 per nodem -2，respectively，which were 78.8-84.0 and 254.2-258.0 higher than those of the check.In addition，the pods and seeds on the top node of B45 account for 21.3% and 22.5%，respectively. Yield of B45 in 760 m2plot achieved 4895.7 kgha-1with this cultivar in 2008，which was significantly higher than the check.
