日本果树栽培有3个主要特点: 第一,管理面积小而集约化程度较高。日本有75％的果树栽培者,其果园面积为0.5ha以下,而拥有1ha以上面积果园的还不到10％。妨碍果园面积扩大的主要原因是地形特点(地块小,山多)和台风频繁、病虫害严重使得栽培不稳定,需要大量劳力。在日本,几乎栽培各种果树,每0.1ha每年 Japanese fruit tree cultivation has three main features: First, the management of small and high degree of intensive. In Japan, 75% of fruit growers have an area of ​​0.5ha or less, while less than 10% owns more than 1ha of orchards. The main reason for hindering the expansion of the orchard area is the terrain features (small plots and mountainous areas) and frequent typhoons. The pest and diseases seriously make the cultivation unstable and require a lot of labor. In Japan, almost all kinds of fruit trees are cultivated every 0.1ha per year
