矮砧金红苹果盛果期果实外观质量与栽培密度、枝果比、单株产量密切相关。随着栽培密度的增加，果实着色下降，果面水锈发生严重且树龄提早；单果重与植果比、单株产量负相关。利用GM256中间砧生产优质金红苹果，永久性植株合理株距不应小于2．0m，枝果比应大于2.5：1。在2m×3.5m密度下，果实丰产、稳产、优质的适宜负荷量为15．5～18．0kg/株。

Dwarf Golden Apple red fruit full fruit appearance quality and planting density, branch ratio, yield per plant is closely related. With the increase of planting density, fruit coloration decreased, fruit rust occurred serious and early age; single fruit weight and fruit ratio, yield per plant negative correlation. The use of GM256 intermediate anvil production of high-quality golden apple, permanent plant reasonable spacing should not be less than 2.0m, branch to fruit ratio should be greater than 2.5: 1. Under the density of 2m × 3.5m, the yield of fruit is high and stable, and the suitable load of high quality is 15.5-18.0kg / plant.
