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8250~10 500 kg/hm23个档次的农艺措施组合方案为:每公顷播种126.3~144.0 kg、施尿素404.0~472.4 kg、施普钙405.6~532.4 kg、施硫酸钾268.8~332.9 kg,尿素施用方法为底肥70%、蕾肥30%,或底肥50%、枞形肥30%、蕾肥20%。

摘  要:
The relation between 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 which 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 sulfate 268.8-332.9 kg per hectare,urea application-basal 70 % and budding 30 %,or basal 50 %,branching dressing 30 % and budding 20 %.
