摘要: 苹果梨树株行距2m∗5m,树体适宜负载量:初果期15~20kg,好果率占80%以上,盛果期35~40kg,好果率80%以上;枝组负载量的计算公式为y=1.9053x-1.0325;花序适宜结果量1~2个;适宜负载量的树体参数为树高3.5~4.0m,冠径2.0~2.5m,枝类比:初果期长枝占总枝的34%、中枝占30%、短枝占29%;盛果期长枝占总枝的20%、中枝占20%、短枝占60%.叶果比:初果期20~30∶1,盛果期30~35∶1.

Abstract: Good load of aple pear tree that had a area of 2∗5m was 15-20kg at early fruit period,high quality fruit rate was over 90%;at full fruit period,it was 40 kg,high quality fruit rate was 80%;The calculation formula of branch group load was y=1.9053x-1.0325,fruit bearing amount of the inflorecense was 1-2,the parameter of the tree bady for good load was 3.5-4.0m high,tree crown 2.0-2.5m,branches ratio was that long branches was 34% of total branches,middle branch 30%,short branch 29% at early fruit period;long branch,middle branch,short branch were 20%,20%,59%, respectively at full fruit period.The ratio of leaf and fruit was 20-30∶1 at early fruit period, 30-35∶1 at full fruit period.
