【摘要】 本文运用灰色系统理论中的灰色多目标局势决策分析方法对不同品种、密度、种薯大小的块茎产量、结薯数、单薯重、大中薯率、净产值5个目标进行综合评价。结果表明,当效果测度取0.75以上时,其综合局势依次为:(379711.7,60cm× 35cm,50g)>(378711.7,60cm×35cm,70g)>(378711.7,60cm×25 cm,30g)> (378711.7,60cm×25cm,70 g)>(378711.7,60 cm×25 cm,50 g)>(川芋56,60 cm×25cm,50 g)>(川芋56,60cm×25 cm,30 g)>(川芋56,60 cm×35 cm,50 g),为马铃薯高产高效益栽培模式提供了参考依据。更多还原

【Abstract】 Five objectives including tuber yield,tuber number,single tuber weight,large and medium tuber percentage and net output value were evaluated for different populations by using the multiparameter grey strategy analysis method.The result indicated that when effective coefficent is equal to 0.75,the order of comprehensive situation is as following,S₂₂₂>S₂₂₁>S₂₁₃>S₂₁₁>S₂₁₂ >S₁₁₂>S₁₁₃>S₁₂₂,which provides reference of potato cultivation for high yield and high benefit.更多还原
