Effect of Fertilizations on Soil Nutrient Lossin Flue-cured Tobacco Fields and Economic Benefits of Application
摘要
Abstract
To reduce nutrient loss, as well as environmental pollution, in the flue-cured tobacco fields, an experimentation on fertilization and economic evaluation for the operation were conducted.The results showed that the losses on N and P were in the order of:(conventional fertilization + unslaked lime + straw returning directly)> (conventional fertilization + unslaked lime) > (conventional fertilization) > (conventional fertilization +nitrification inhibitors).Compared to the other treatments,the (conventional fertilization + nitrification inhibitors) reduced the losses of N,P and K through the runoff water by 13.16%-23.16%,10.72%-28.41% and 10.72%-23.16%,respectively.The concentrations of N,P and K in the seepage also indicated that the (conventional fertilization + nitrification inhibitors)significantly reduced the nutrient losses,more than the other treatments.It appeared that the fertilization practice was an effective way for the loss reduction.Meanwhile,data on tobacco yield (2 702.40 kg·hm-2 ),total value (50 345.10 yuan·hm-2 )and average price on the market (18.63 yuan·kg-1 ) showed improvements over those obtained with the (conventional fertilization),i.e.,399 kg · hm-2 on yield, 10288.95 yuan· hm-2 on total value,and 1.24 yuan·kg-1 on market price.关键词
