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 principles and methods of agricultural systems engineering were applied in this experiment. The relationships among density, nitrogen, phosphorus and potash fertilizer application rates and five main cultivation factors during nitrogen fertilizer application and yield of stem were studied. Through the field experiment, the yield parameters of original stems were measured to establish the mathematical model of high-yielding cultivation of flax stems. The effects of cultivation factors on the yield of flax, the interaction and the best combination of agronomic practices were discussed. Cultivation provides a scientific basis.
