我场于一九六○年大量种植柑桔。在此之前的试种阶段,本场没有自育苗木,苗木来自黄龙病区,六○年种的3939亩苗木也购自当地果场。前者因带病,在一九六二年发现病害后,蔓延甚快,于一九六七年全部淘汰;后者因苗木质量差且砧木杂乱,经过整顿共淘汰2502亩,只留下1601亩。我们体会到,搞柑桔生产不搞育苗是不行的,不仅质量得不到保证,发展也受限制。因此,我们从 I made a lot of citrus in 1960. Prior to the trial stage, there was no self-nurturing seedlings in the field and the seedlings were from Huanglong Ward. 3939 mu of seedlings from 60 years were also purchased from local fruit farms. As a result of the disease, the former developed rapidly in 1962 and was completely eliminated in 1967. The latter was phased out due to the poor quality of seedlings and rootstocks. After the rectification, a total of 2,502 mu were eliminated, leaving only 1601 mu . We realized that it would not work to engage in citrus production without nurturing seedlings. Not only quality could not be guaranteed, development was also limited. Therefore, we from
