一、前言枇杷是我国特产水果之一,它的果实初夏成熟,正是一年中最缺水果时期,因此世界主产国正在大力发展枇杷.但是枇杷单位面积产量较低,据不完全统计,一九八二年平均亩产量,莆田县为366斤,余杭县260斤,管理较好的黄岩县民主乡也不过1213斤,其中民主村丰产园最高达到5000斤;莆田县山牌村约1500斤.而日本1975～1976年全国平均约949斤.为了提高其单位面积产量,特分析研究产量与各主要器官间关系,为栽培管理的合理措施提供依据.
I. Introduction Loquat is one of the specialty fruits of our country.Its fruit is mature in early summer, which is the period of the most fruit shortage in the year.It is the major producing country in the world that is developing loquat.However, the output of loquat per unit area is low, according to incomplete statistics, The average yield per mu in 1982 was 366 kg in Putian County and 260 kg in Yuhang County and 1213 kg in the well-managed Huangyan County Democracy Township, with the highest yield in the Democracy Village reaching 5,000 kg. The Sanwei Village in Putian County was about 1,500 Kg, while Japan averaged about 949 kg from 1975 to 1976. In order to improve its yield per unit area, the relationship between yield and major organs was analyzed to provide the basis for reasonable measures for cultivation and management.
