- 摘要:
- 采用3个基因型品种,2种栽培模式,设置3个处理,研究半矮秆大豆窄行密植超高产栽培技术产量性状及产量结构,旨在为超高产大豆研究与应用提供技术依据。结果表明:在窄行、密植、高肥水条件下,B45处理由于采用半矮秆品种植株矮、底荚低、秆强不倒,虽然单株荚数、粒数显著低于对照,但由于密度增加,群体荚数、粒数显著增加,每节位平方米荚数、粒数分别达到145.1个和411.7个,分别较对照增加78.8~84.0个和254.2~258.0个,顶荚部位荚、粒数分别占总数的21.3%和22.5%。产量极显著高于对照处理,2008年在760 m2面积上,大豆产量达到4 895.7 kghm-2。
- 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.
