Abstract:
The results show that the plant dry-matter accumulation,the pod-yielding and the pod-volume increasing of peanut under film-mulching(FM)and no-mulching(NM)condi-tion can all be described by the logistic model.(1)The turning point of the plant dry-matter increasing rate appeared on July 20th,1986(July 24th,1987)for the peanut growing unber FM,but on July 12th-July 13th,1987 unber NM.The greatest increasing period is just around the turing point.(2)Turning of the pod-voiume increasing rate appeared on July 13rd,1987 for the peanut growing under FM,but on July 24th,1987 under NM.The greatest increasing period is around the turning point.(3)The turning point of the increasing rate of the pod dry-matter per plant appeared on Aug.5th,1987 under NM.And,the greatest increasing period is around the turning point.
