扦插法是米兰繁殖中比较常用的方法。在南方温度高、湿度大的情况下,扦插易成活;而北方干旱低温,直接扦播较为困难,成活率较低。近年来,笔者采用先对插穗进行萘乙酸处理然后扦插的方法,取得了较好的效果,成活率达83.8％。一、苗床设置及基质处理苗床宜选在背风向阳处,东西走向,宽1——1.5米,深60厘米,长可随意而定。池内壁用砖垒砌,池底松土20厘米。晾一段时间后,耙细整平,再垫10厘米厚的过筛炉渣,并填入20厘米深的营养土,最上层覆蛭石6——8厘米。这些基质均须经1——3％的硫 Cutting method is more commonly used in Milan breeding methods. In the south of the high temperature and humidity conditions, cuttings survive; while the northern drought low temperature, direct cutting is more difficult, the survival rate is low. In recent years, the author used the method of treating naphthaleneacetic acid and cuttings first, and achieved good results, with a survival rate of 83.8%. First, the seedbed settings and substrate treatment Seedbed should be selected leeward sunward, east-west direction, wide 1--1.5 meters, 60 centimeters deep, long may be free. Pool wall brick masonry, pond soil 20 cm. After drying for some time, rake fine and flat, and then pad 10 cm thick sift slag, and fill 20 cm deep nutrition soil, the uppermost vermiculite covered 6--8 cm. These matrices must be 1--3% sulfur
