摘要
在1997—2003年进行长期定位施肥的基础上,研究了氮、磷、钾配合施用对花生产量和品质形成的研究。结果表明:与不施肥处理相比,长期施用N肥可以提高花生籽粒产量和籽粒中蛋白质含量;施用NK肥,籽粒中粗脂肪含量降低,施用NP肥,降低了籽粒中蛋白质含量;施用PK肥,降低籽粒中蛋白质含量:施用NPK肥,显著地提高了籽粒产量和蛋白质含量,说明NPK肥配合施用有利于籽粒产量的提高和籽粒品质的形成,有利于保持和提高土壤肥力。
Based on long -term locating fertilization experiment from 1997 to 2003 we studied the effect of combined application N, P and K fertilizers on yield and quality of peanut. N fertilizers significantly affected the yield and protein content of peanut grains. The long - term combined application of N and P fertilizers or P and K fertilizers decreased protein content of peanut grain. The long - term combined application of N, P and K fertilizers significantly however increased yield and protein content of peanut grain, proved that co - addition of N,P and K could keep and improve soil fertility and be benifit to the grains improvement.
