本研究根据系统工程原理,采用数学模型方法,从研究红麻个体发育、群体发展与主要农艺措施的数量关系入手,探讨农艺措施综合效应对两种不同耕作制(春麻、麦茬红麻)的造纸用红麻产、质量的影响,系统地论述了播种期、栽培密度、N、P、K施用量等农艺措施对造纸用红麻产量和质量的综合效应及互作效应,阐明了红麻茎杆皮/骨比值、髓占比的时空变化规律,明确红麻高产优质的途径。建立的数学模型可为相同自然条件下不同耕作制度、种植习惯和生产力水平的麻区提供相应的系列高产、高效优化衣艺措施组合。本研究形成的造纸用红麻高产优质、高效模式栽培技术成果为建立我国造纸红麻原料基地提供了农业技术依据。本专题研究已通过国家验收和鉴定,该成果居国际同类研究先进水平。
Based on the principle of system engineering and using mathematical model, this study started with the study on the relationship between individual development, population development and major agronomic practices in kenaf, and discussed the effects of agronomic measures on the effects of agroforestry and kenaf The effects of agronomic measures such as sowing date, planting density, N, P, K application rate on the yield and quality of kenaf papermaking were systematically discussed. The effects of kenaf yield and quality on papermaking were clarified. Stalk skin / bone ratio, changes in the temporal and spatial distribution of medullary ratio, clear kenaf high yield and quality of the way. The established mathematical model can provide a series of high yielding and efficient optimized clothing combination for different areas with different cultivation systems, planting habits and productivity under the same natural conditions. The research results of high-quality, high-efficiency cultivation techniques for kenaf papermaking in papermaking provided agricultural technical basis for establishing the raw material base for kenaf papermaking in our country. The research has passed the national acceptance and accreditation, the results of the international advanced level of similar research.
