过去在柑橘大面积生产上,大多推行开挖定植穴的方式,直接栽植建果园。近年来,在南充市嘉陵区试验推广深沟宽厢聚土起垄栽培建园模式。尤其是在水田或地势低洼的地方建果园,早结丰产效果好,实现了头年栽树,第二年试花,第三年丰产(亩产达1000kg以上)的目标。柑橘深沟高厢聚土起垄栽培技术要点如下:一、建园要点1.株行距新建果园立地条件若是水田,坝土时,株行距按3m×5m或4m×5m定植,南北走向,坡地果园株 In the past in large-scale production of citrus, most of the implementation of excavation planting hole approach, planting orchards directly. In recent years, experiment in Jialing District of Nanchong City to promote the cultivation of deep furrow ridge Ridge Cultivated Park mode. Especially in paddy fields or low-lying areas to build orchards, early fruiting and good results, the first year to achieve the tree, the second year of flowers, the third year of high yield (mu yield of more than 1000kg) goal. The main points of citrus tillage and ridge cultivation techniques are as follows: I. Key points for building a garden 1. When the spacing between new rows of rows of orchards is up to 3m × 5m or 4m × 5m for paddy and dam soil, Orchard strains
