对福建省柑桔健康栽培示范园的初步评估

80年代，福建省在5个地区建立柑桔示范园（曾称为无病母本园）。按照健康栽培的观点严格实施，在隔离的地区建园，种植无病毒的苗木，对黄龙病、病毒病及其虫媒定期检测，及时铲除病株的防治虫媒，加强土壤、肥、水的管理措施。这样的柑桔健康栽培示范园，与对照柑桔园相比，前者的植株生长强壮而抽梢整齐，结果优质而高产，经济效益延长5a以上。在1982-1999年间，对示范园的观察与调研中发现，黄龙病和病毒病的发生，完全取决于能否阻止其虫媒的侵入。

Preliminary evaluation on citrus demostrative plantation of health management in Fujian province

In 1980's, citrus demonstrative plantations of health management(called virus-free mother tree plantations ) were established in five counties in Fujian province. From the point of view of health management, the following requirements were carried out strictly: new citrus plantation was settled in isolated area far from the diseased one; the free-virus nursery seedling was used for planting material; Huanglongbing, virus diseases and their vectors were examined periodically by monitoring technique; elimination of diseased plants and prevention of insect vectors were carried out in time and management of soil, fertilizer and water was kept in good manner. The comparison of citrus demonstrative plantation of health management with control plantation in general management show that the citrus plants in former plantation grow strong and their shoots push in time, the quality of citrus fruit was superfine and quantity was great, and the economic effect of the production has prolonged for more than 5 years. The observation and survey made through out the years of 1982-1999 show that the occurrence of citrus Huanglongbing and virus diseases were completely dependent to the invasion of their insect vectors to citrus demonstrative plantations.
