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.
