限根对油桃幼树生长和结果的研究

以油桃幼树为试验材料,在设施栽培条件下研究限根对油桃生长结果的影响,探索限根后油桃生长结果特性的变化.以期为建立设施栽培条件下的油桃优质丰产的高效模式和限根栽培的推广应用提供理论依据.结果表明:3种处理对早红宝石幼树的枝条加长生长曲线相似,最终长度表现为CK＞TR2＞TR1,处理TR1对枝条加长生长的抑制作用最明显.同时还表明,枝条加粗生长的节奏亦相同,粗度最终表现为TR2＞CK＞TR1,处理TR1对枝条加粗生长抑制作用最大.

Studies on the Influence of Early Nectarine Tree''''s Growth and Fruition by Limiting its Roots

The tree's growth and fruition were evaluated of early nectarine to research the influence by limiting roots.So we could provide bases for the popularizing of limiting roots planting.The results indicated that there was no remarkable difference on the curve's lengthen between the three handlings,and their length character expressed CK>TR2>TR1,with TR1 controlling curve's length achieved most obvious effect.The results also indicated that there were same rhythm between the three handlings on the curve's thicken,and their thick character expressed TR2>CK>TR1,also with TR1 controlling curve's thick achieved most obvious effect.
