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。
Good load of aplepear tree that had a area of 2×5m was 1520kg 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=19053x-10325,fruit bearing amount of the inflorecense was 1-2,the parameter of the tree bady for good load was 35-40m high,tree crown 20-25m,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.
