石灰改良白浆土对大豆的影响

Lime Modified Soil Albic Impact on Soybean

采用小区对比的方法分析石灰对土壤pH值、大豆的影响,结果表明,石灰能够提高酸性土壤pH值、降低大豆株高、增加大豆茎粗,有提高大豆产量的作用。每667m2施石灰30 kg,增产6.2%,达到显著水平;每667m2施石灰15 kg、45 kg,增产2.6%、4.5%,均未达到显著水平。

Comparison of methods of cell analysis of lime on soil pH, the effects of soybean, the results show that the acidic soil with lime to increase pH, reduce soybean plant height, stem diameter increased soybean, have the effect of enhancing the role of soybean production. Shi 667m^2 lime per 30 kg, increasing by 6.2%, reaching a significant level; Shi 667m^2 lime per 15 kg, 45 kg, increasing by 2.6%, 4.5%, did not reach significant level.
