【摘要】 打破传统牡丹催花技术中单一空气加温的形式,进行催花植株的根际加温,有利于促进牡丹新枝、花蕾的生长发育,在一定时间范围内提早开花.改变传统的土壤盆栽催花,应用无土栽培,且使根际温度保持在12～18℃之间,有利于牡丹萌生新根,从基质中吸收养分,促进开花.更多还原

【Abstract】 While raising the air temperature in greenhouse, substrate warming promoted the growth of new shoots and flower buds of tree peony (\%Paeonia suffruticosa\% Andr.) during forcing culture in winter. Roots grew better in soilless substrate than in soil and the absorption of nutrient was increased. Substrate temperature 12～18 ℃ is optimal to root growth and absorption of nutrient.更多还原
