临海县是浙江省以种植温州蜜柑为主的柑桔基地县之一。全县现有桔园5万余宙;其中温州蜜柑面积约为4.5万亩。1982年全县温州蜜柑产量为30余万担,占全县柑桔总产量的90%以上。近年来,柑桔产量每年以10—20%的增长速度上升。自七十年代后期开始,临海县涌现了一批以生产大队为单位的温州蜜柑高产稳产园,连年亩产都保持在5000斤以上。本文对这些高产园的肥培管理水平与树体营养状况,以及与产量的关系进行了初步探讨。
Linhai County is one of the citrus base counties in Zhejiang Province that mainly grows mandarin oranges. The existing orange garden in the county more than 50,000; of which the area of about 15,000 acres of Satsuma. In 1982 the county of Wenzhou Satsuma production of more than 30 million, accounting for more than 90% of the county’s total citrus production. In recent years, citrus production has risen by 10-20% annually. Since the late seventies, a number of high-yielding and stable production bases of Wenzhou Satsuma mandarin have emerged in Linhai County. The output per mu in successive years has remained above 5,000 kg. In this paper, the relationship between the management level of fertilizer cultivation in these high-yielding gardens and the tree nutrition status and the relationship with the yield was discussed.
