2) simulated irrigation and rainfall
模拟灌溉和降雨
1.
The BBFs of different controlled N ratio can effectively stabilize the pH and EC; reduce the loss of NH4+-N, NO3--N and other N forms, the same to P, K; maintain the soil nutrients farthestly under the condition of simulated irrigation and rainfall.
在模拟灌溉和降雨条件下,不同控氮比控释掺混肥能有效稳定和保持土壤淋溶液的pH值和电导率,降低了硝态氮、铵态氮等形态氮素和总氮的淋失,有效减少了磷素和钾素的淋溶,最大限度地保持了土壤养分;不同控氮比例控释掺混肥控氮比例越高,氮、磷、钾等养分淋失越少,最大限度地提高肥料养分的利用率;控氮比例为59%的控释掺混肥具有“前控后保”的特点,在生产实际中具有极大的推广应用价值。
