矮化密植是提高果园早期产量。提高土地利用系数的重要改制措施。在欧洲国家有的达到了新建果园或现有果园面积的70%以上。 矮密提高早期产量, 而叶面系数有效率低,最高产量将不及希植大树.两种栽培制的比较虽然应从经济核算的总成果来判断。是否也应研究在时间上发挥两种栽培 Dwarf and close planting is to improve the early yield of orchard. Improve the land use coefficient of the important restructuring measures. Some European countries have reached new orchards or existing orchards over 70% of the area. Dwarf density to improve early yield, and the low efficiency of leaf coefficient, the maximum yield will be less than Xichu big tree .Comparison of the two cultivation system should be judged from the total economic accounting results. Whether or not to study two cultivars in time should also be studied
