为了弄清批把采果期与产量和品质的关系，笔者于lwt年进行了分期采果试验。试验选负载量和树冠大小基本一致、树龄为7年的华宝2号作试材。于5月15、20、25、对日分4次采果，单株小区，3次重复。每期采果进行单株称重，统计果数，计算单果平均重量，测定果实纵横径、可溶性固形 In order to find out the relationship between batch harvesting and yield and quality, the author carried out staged picking test in lwt year. The test load and crown size are basically the same, the age of 7 years Warburg 2 for the test material. On May 15, 20, 25, on the Japanese sub-4 pick fruit, single cell, 3 times repeated. Each stage of fruit picking weight, statistics, the number of fruit, calculate the average weight of fruit, the measured fruit vertical and horizontal diameter, soluble solid
