Abstract：Adopting an appropriate planting densityfor Chinese chestnut cultivationcan fully utilize light energyand soil fertility，therebyimproving yield.asedonproduction practices，intheinitialstageoforchardestablishment，theplantspacing and row spacing were set narrower than the optimal density （ 2m×3m ）by adding temporary plants between permanent plants.Subsequently，plants withoverlappingcanopies andlight limitation were graduallremoved，or temporaryplants were thinned out，ultimately restoring the orchard to the conventional density of 4m×6m ， so as to increase the early-stage yield.

板栗树的栽植密度，在20世纪50年代初至60年代末生产上多用传统的高干、大冠、稀植和粗放管理的果粮兼用方式，前期光能利用率非常低，产量上升缓慢。（剩余4370字）
