温州桔区自古有密植栽培的经验。早在宋代韩彦直所撰《桔录》(1178年)中就提到“柑桔……每株相去七、八尺”。宋代一尺相当于现代30.72厘米,如是推算当时的株行距为2.15～2.46米,亩栽110～145株。 近半世纪来,枳砧的应用逐渐普遍,比朱栾砧瓯柑树形矮小,更适宜密植,并取得良好生产效益。鉴于温州是世界上开展柑桔矮化密植最早的桔区之一,总结枳砧瓯柑矮化密植的经验将具有重大的现实意义。
Wenzhou orange region since ancient times has close planting cultivation experience. As early as the Song Dynasty Han Yan straight “Orange recorded” (1178) mentioned in the “citrus ... ... each plant to go seven or eight feet.” A foot of Song Dynasty is equivalent to the modern 30.72 centimeters, so calculate the line spacing was 2.15 ~ 2.46 meters, planted 110 to 145 acres. For nearly half a century, the application of Trifoliate ancestors is becoming more and more common. It is shorter and more densely populated than the potted cotyledons of Castanopsis Luangensis and achieved good production benefits. Given that Wenzhou is one of the earliest citrus growing areas in the world, it is of great practical significance to summarize the experience of dwarfing and close planting of Citrus aurantium.
