柑桔育苗一般要经过播种、幼苗移栽、单砧嫁接等阶段。1987～1989年,我们采用枳种点播双砧嫁接法,苗木成活率高,根系发达,生长速度快,分枝多,结果早。现将具体作法简介如下: 清明前取出层积枳种,采用宽窄行点播,宽行行距35厘米,窄行行距20～25厘米,每组两粒种子(双砧)间的距离为4厘米,相邻两组种子间的距离为12厘米。于翌春砧苗萌动至展叶前嫁接,将每组的两株砧苗在同一高度剪断,分别在两砧相对的一 Citrus nursery generally go through sowing, seedling transplanting, single-stage grafting and other stages. From 1987 to 1989, we used the method of on-demand double-root grafting of fresh and fonn of tree species. The seedling survival rate was high, the root system was developed, the growth rate was fast, the branches were many and the result was early. Here are the specific practices are as follows: Ching Ming removed layer of Zhizu stratification, the use of wide and narrow lines on demand, wide line spacing of 35 cm, narrow line spacing of 20 to 25 cm, two seeds per group (double anvil) the distance between the 4 cm, The distance between two adjacent seeds is 12 cm. In the next spring anvil seedling sprouting before the exhibition leaf grafting, the two anvil seedlings in each group cut at the same height, respectively, in the anvil relative to the two
