摘要
研究了阿里亚娜(Ariane)在秋播条件下的播种量、氮、磷、钾肥施用量及氮肥施用方法5个主要可控栽培因子与原茎产量之间的效应关系及其数学模型。获得3125套农艺措施组合方案,优选出目标原茎单产8250~10500kg/hm^2 3个档次的农艺措施组合方案为:每公顷播种126.3~144.0kg、施尿素404.0~472.4kg、施普钙405.6~532.4kg,施硫酸钾268.8~332.9kg,尿素施用方法为底肥70%、蕾肥30%,或底肥50%、枞形肥30%、蕾肥20%。
The relation betwecn the stem yield and 5 cultivation practices, including seed rate, N, P, K application rates and N application methods, and its math model were studied in Autumn sown fibre flax Ariana. 3 optimized combinations ,s4fich yield 8250 - 10500 kg/hm^2 were obtained from 3125 combination of the practices: seed rate 126.3 - 144.0 kg, Urea 404.0 - 3472.4 kg, Calcium superphosphate 405.6 - 532.4 kg potassium sul- fate 268.8 - 332.9 kg per hectare, urea application-basal 70 % and budding 30 % , or basal 50 %, branching dressing 30 % and budding 20 %.
