摘要
由于种子的播种量不精确,化肥的施用存在利用率低、污染环境等问题。为了解决这些问题,必须进行精准变量播种施肥,变量播种施肥技术是精准农业的重要内容之一。文章介绍了精准农业的基本概念,并以精准农业为背景,介绍了变量播种施肥的概念及关键技术,探讨了当前变量播种施肥技术存在的问题及未来的发展前景。
In China, there are many problems on imprecise seeding and application of chemical fertilizer, such as inefficient application and environment pollution. In order to solve these problems, the precision variable rate seeding and fertilization should be developed. Variable rate seeding and fertilization technique is one of the most important content of precision agriculture. With the background introduction of precision agriculture, the conception and key of variable rate seeding and fertilization technology were introduced. The defects and pros- pects of development of variable rate seeding and fertilization technique were discussed.
