应用矮化中间砧进行苹果矮化栽培时,普遍存在着树势变弱的问题。长野县果树试验场为了解决这一问题,于1978年开始进行了M_(26)中间砧(基砧为圆叶海棠)富士矮化树的定植培土试验。试验设基砧圆叶海棠高于地面5～7厘米的浅植区和M_(26)中间砧埋入土中一半的培土区二个处理。结果看出,浅植区由于中间砧上发生气根束,树势弱,树体小;培土区树体
The application of dwarfing intermediate anvil dwarf apple cultivation, there is widespread problem of weakening of the tree. Nagano Prefecture fruit tree test site In order to solve this problem, began in 1978 M_ (26) intermediate anvil (Fuji lobular Begonia) Fuji dwarf tree planting test. The experiment was based on the root aniseed lobot Begonia 5 to 7 cm above the ground shallow planting area and M_ (26) intermediate anvil buried in soil half of the soil area two processing. The results showed that the shallow planting area due to the rootstock on the rootstock anvil, tree potential is weak, small trees; cultivated area tree
