摘要: 为进一步明确接种根瘤菌时配施钼肥在大豆生产中的肥效效应,通过2013年和2014年2年田间试验,研究了接种根瘤菌及配施钼肥对大豆干物质积累、分配及产量的影响。结果表明:结荚期至鼓粒期,接种根瘤菌处理(R)的大豆干物质积累与未接种处理(CK1)无显著差异;而接种根瘤菌并配施1%浓度钼肥处理(R+Mo1)的大豆干物质积累量显著高于接种根瘤菌并配施2%浓度钼肥(R+Mo2)、单接根瘤菌处理(R)和单施钼肥处理(Mo);接种根瘤菌并配施1%浓度钼肥(R+Mo1)提高了大豆开花至结荚期的生长速率。2013年和2014年2年试验结果表明,接种根瘤菌并配施1%浓度钼肥(R+Mo1)使大豆产量分别较接种根瘤菌(R)增产20.46%和9.63%。试验结果证明,大豆农业生产中接种根瘤菌并配施1%浓度的钼肥,促进了大豆生育后期的干物质积累以及开花至结荚时的生长速率,进而达到了增产效果。

Abstract: Field experiments were conducted to study the effect of rhizobium and combined molybdenum on dry matter accumulation, distribution and yield of soybean in 2013 and 2014. The results showed that the dry matter accumulation of soybean inoculated rhizobium treatments (R) had no significant difference compared to non-inoculated treatment (CK1) in podding and seeding stages. While the dry matter accumulation of soybean inoculated rhizobium and combined 1% molybdenum treatment (R+Mo1) was greater than that of inoculated rhizobium and combined 2% molybdenum (R + Mo2), inoculated rhizobium only (R) and fertilizing 1% molybdenum only treatments (Mo). In addition, the growth rate of soybean was also increased by inoculated rhizobium and combined 1% molybdenum when soybean was flowering to podding. The yield of soybean inoculated rhizobium and combined 1% molybdenum increased by 20.46% and 9.63%, respectively, compared to that of only inoculated rhizobium treatments in 2013 and 2014. Hence, the dry matter accumulation of soybean and the growth rate of soybean from the stage of flowering to podding were increased by inoculated rhizobium and combined 1% molybdenum, which led to the soybean yield increase.
