试验地设在浙江省慈溪市范市镇。4 a的研究表明：菜用香椿矮化栽植密度以19 500～24 000株*hm－2为宜，采用菱形双行种植有利于香椿生长和增产，整形修剪是香椿矮化的主要配套技术措施和提高产量的有效手段。香椿树体宜整修成灌木形、扫把形和分层形等，结合修剪、环割、采摘和更新枝留养等配套技术，控制树高在2 m左右。菜用香椿多年生长后，抽枝萌芽能力逐年减弱，可采用断根方法，利用根蘖进行更新。表5参3

The experiment was made in Fanshi Town of Cixi City from 1995 to 1998．The results showed that the planting density of Toona sinensis used as picking tender shoot and chit fall well in to 19 500 to 24 000 plants per hectare．Adapting diamond double-line planting benefited tree growth and increase production．Pruning and cutting with girdling，chit plucking，reproducing branch raising were main ways in dwarf culture，with increasing the yield of tender shoot and chit of Toona sinensis．Table Toona sinensis should have a tree form of bush or broom or storied branch，by pruhing with a tree height of 2 meters or so．After several times of plucking，branch sprouting begin to reduce year by year，and could be renovated by root sprouting．
