中文摘要:

为探讨扁桃小麦间作模式下成龄扁桃树形改造对小麦生长及产量的影响，以11年生扁桃品种晚丰为试材，研究了扁桃主干分层形（对照）和高干开心形（提干、落头改造处理）两种树形对不同间作区域小麦营养生长、旗叶性状、旗叶光合能力及产量构成指标的影响。结果表明，扁桃主干分层形树冠体积大，枝叶密度较高，结果部位主要集中在树冠外围，对间作区特别是冠下和近冠区小麦营养生长和产量影响较大；高干开心形，改造当年对扁桃产量无较大影响，与主干分层形相比单位体积负载量显著提高，单位体积枝条量显著降低，改善了间作区域的光照条件，显著提高了各间作区域小麦千粒重、单穗粒重、单位面积有效穗数等产量构成指标。高干开心形是成龄扁桃间作系统较为理想的改造树形。

英文摘要:

To explore the influence of tree from modifying on wheat vegetative growth and grain yield in mature almond wheat intercropping system. The effects on wheat vegetative growth condition,flag quality,leaf photosynthetic capacity and grain yield of two tree form of trunk delaminating shape (ck) and high trunk open centre shape (rising trunk and reducing height modifying treatment) of 11 years old Wanfeng almond tree were studied.The result showed that,trunk delaminating shape had bigger volume of canopy,higher density of branches and leaves and with the fruits positions mainly concentrated in outer side of the crown. The trunk delaminating shape had large influence on the vegetative growth and yield of wheat in the intercropping area,especially under and nearly crown area. The high trunk open centre from had little effects on the almond yield in the first year,but could effectively reduce the canopy volume and foliage density,which could effectively improve wheat growth condition in the intercropping system and increase the 1000 grain weight,grain weight per spike of wheat significantly. High trunk open centre from was the suitable modifying from for mature almond wheat intercropping system.
