菜用香椿矮化栽植密度以 19 500～24 000 株/hm2为宜，采用菱形双行种植方式有利于香椿的生长和产量，整形、修剪是香椿矮化和提高产量的主要措施，通过整形可使树形成灌木形、扫帚形、分层形等，结合截干、环剥及采摘回缩等措施可控制树高在 2m 以下。菜用香椿经多年生长后，抽枝、萌芽能力逐年减弱，可采用断根促萌来更新。

Rational planting density of vegetable dwarf trees of Toona sinensis is 19 500～24 000 Plants/ hm2. Rhomboid double-line planting pattern is good to its growth. Triming and reshaping are the Main measures to make it become dwarf and improve its yield. Its height can be controlled below 2m , by reshaping, trunk cutting, ring striping ,etc. After several years of growth, its capability of branch development and Sprouting gradually decreases. They can be regenerated by cutting roots to improve sprouting.
