- 摘要:
- 为给大豆高产施肥提供依据,以克交05-174和克交07-584为试验试材,研究了优化施肥对大豆氮、磷、钾积累及产量的影响。结果表明:优化施肥显著地提高了大豆植株生育中后期的氮、磷积累量,提高了整个生育期钾素的积累量。与对照相比,优化施肥使克交05-174产量提高了9.6%,克交07-584产量提高了25.2%,达5%显著水平。
- Abstract:
- In order to provide basis for soybean high yield fertilization,a plot experiment with two soybean varieties Kejiao 05-174 and Kejiao 07-584 was conducted to study the effects of nutrient management on NPK accumulation and yield of soybean.The results showed that optimized fertilization significantly increased the N and P accumulation in soybean plants at middle to later stages,and significantly increased K accumulation over the whole growth stage.The yield of Kejiao 05-174 increased by 9.6%(P<0.05),and Kejiao 07-584 increased by 25.2%(P<0.05)compared with CK.
