摘  要:
通过对毕节地区小麦平衡施肥进行研究,得出小麦平衡施肥的参数及最佳施肥方案。研究结果表明,小麦产量与有机肥的施用量呈直线关系,而与化肥的施用量各县表现却不同,大方县小麦产量与磷肥(普通过磷酸钙)的施用量三直线关系,毕节市、黔西县施用量是曲线关系,各试验点小麦产量均与尿素施用量呈典型的曲线向下关系。施用有机肥与磷肥对小麦产量的提高有着重要作用。而氮肥的施用不宜过多。

摘  要:
This paper deals with field experiments of different fertilizers for wheat in Bile area so as to obtain balanced fertilizing constant and rational rate of applied fertilizers. The results showed that the yield of wheat had a straight correlation with the quantities of organic fertilizer and the correlations between the yield and the quantities of inorgnic-N or P fertilizer were different, of which inorganic-N had a curved correlation in all field experiments and inorganic-P had a straight correlation in Dafang but a curved correlation in Bine or Qianxi. The rational rate of organic fertilizers, inorganic-N and inorganc -P fetilizers could significantly increased the yield of wheat, of which the suitable quantities of inorganic -N fertilizer were more importent.
