摘要
程述汉等．红富士干周增长规律的数学模型．在对鲁西平原上１～１４年生红富士苹果树干周大量调查的基础上，研究了红富士苹果树干周增长规律及负荷量对干周增长的影响；
The experimental variety is Red Fuji planted from one to fourteen years.On the bases of thorough observation,we have done researches including the increasing regular of trunk girth;the effect of load to the increase of trunk girth;the mathematical model of the increasing regular of trunk girth.
