宁夏农户施肥调查与评价

针对2005—2008年宁夏部分县市农户施肥调查资料,分析了当前宁夏主要粮食作物养分来源、施肥现状、化肥养分投入量以及化肥的贡献.结果表明,推广应用测土配方施肥技术,农户施肥结构和科学施肥水平有了明显提高,肥料资源配置趋向合理,但施肥成本高、有机肥投入不足仍然是丞待解决的问题.

According to the data from fertilization by farmers in some counties of Ningxia from 2005 to 2008, current main nutrients for crops, actual state of fertilization, input of fertilizer nutrients and contribution of fertilizer were analyzed. The results showed that popularization of fertilizing with prescriptions by soil testing greatly improved fertilizing structure and level of farmers to make the allocation of fertilizer resources tend to reasonable. But high cost for fertilization and inadequate of input of organic manure were urgent problems to be resolved.
