多因素播种施肥技术研究

Study on multifactor technology of sowing and fertilization

针对我国农业中存在播种施肥量不精确的问题,系统地研究了变量播种施肥的方法、技术,针对土壤养分的差异,为使作物达到高产、高效,应用系统分析和优化设计的方法,对要素组合进行了优化研究,为科学播种施肥提供了参考依据。

Based on the inexact sowing and fertilizing amount in agriculture of China, this paper systematically studied the method and technology of variable sowing and fertilization, and by viewing of the difference in soil nutrition, the methods of system analysis and optimization design are employed in order to realize the purpose of high and stable yield of crop. This paper also provides a reference for the scientific sowing and fertilization by the optimization study of the main factors combination.
