龙游县地处浙西金衢盆地中段,气候温和,雨量充沛,适宜发展柑桔生产。解放初期全县柑桔面积0.10万亩,1986年已发展到3.3万亩,其中82.2％的桔园建在红壤丘陵。可是,不少桔园产量一直很低,甚至无果。据1984年果树资源普查,全县10年生以上柑桔中,不结果树占19.2％,5～9年生柑桔中,不结果树占42％。1984年全县柑桔结果园平均亩产167公斤,折合株产仅3.5公斤。全县5年生以上,亩产250公斤以下的低产桔园有108个,约2692亩,共179041株,占全县5年生以上柑桔的61.6％。其中20个低产园一果不挂。低产桔园中,以温州蜜柑比重大,占75％。针对上述情况,我们从1984年起,连续三年进行了红壤丘陵柑桔低产园改造试验和示范推广,获得了一定成效,现综合简
Longyou County is located in the middle of western Zhejiang Qujing basin, mild climate, abundant rainfall, suitable for the development of citrus production. In the early liberation of the county citrus area of 0.10 mu, 1986 has been developed to 3.3 million mu, of which 82.2% of the orange garden built in red soil hills. However, the output of many orange groves has been very low and even fruitless. According to 1984 fruit resources survey, the county more than 10 years of citrus, fruit trees accounted for 19.2%, 5-9 years of citrus, fruit trees accounted for 42%. In 1984 the county citrus fruit orchard average yield of 167 kilograms, equivalent to only 3.5 kilograms of strain. Over 5-year-olds, there are 108 low-yield orange orchards with a yield of less than 250 kilograms per mu, about 2692 mu, with a total of 179041 strains, accounting for 61.6% of the citrus in the whole county. One of 20 low-yielding garden fruit is not linked. Low-yield orange garden, with a large proportion of Wenzhou orange, accounting for 75%. In response to the above, we started from 1984 onwards, for three consecutive years of red soil hilly citrus low-yielding garden transformation test and demonstration of promotion, obtained some success, is now integrated Jane
