云南宾川县亚麻生产技术系列报道之三 亚麻原茎高产栽培综合农艺措施数学模型的研究

Research on the Mathematic Model of Comprehensive AgriculturalMeasures for High Yield of Flax

试验应用农业系统工程学的原理和方法,研究探讨了密度、氮、磷、钾肥用量及氮肥施用时期五个主要栽培因素与原茎产量的相互关系。通过田间试验测得原茎产量参数,建立了亚麻原茎高产栽培数学模型,初步探讨出各栽培因素对亚麻原茎产量的影响、相互作用关系及最佳农艺措施组合方案,为亚麻原茎高产栽培提供科学依据。

The relationship between stem yield of flax and 5 main factors (planting density, the applying amount of N, P, K and the applying date of N) was studied by systematic engineering method. The role of each cultivation factor to stem yield and relationship among all factors were preliminarily specified after the mathematic model of comprehensive agricultural measures was optimized.
