苗木,是发展山楂生产的物质基础。苗木质量对于结果的早晚、产量的高低、品质的优劣、寿命的长短、树体的高矮都有明显的影响。因此选择适宜的砧木、培育优质的壮苗是发展山楂生产的首要任务。山楂育苗比较困难,近年来各地已取得了一些经验。现将晋东南地区山楂育苗经验介绍如下。一、砧木的选择与利用采用不同种类的山楂砧木,嫁接后对树体的影响不同。如用湖北山楂嫁接后,树体高大,生长旺盛,寿命长;用野生山楂嫁接后树体低矮,结果早。当地用山定子、杜梨、海棠作砧木均表现不好。用山定子嫁接后当年成活率达75%,次年生长80—100厘米高,到第三年就出现自衰死亡的现象。因
Seedlings, is the material basis for the development of hawthorn production. Seedling quality for the results of the morning and evening, the level of output, the quality of the merits, the length of life, the height of the tree has a significant impact. Therefore, the choice of suitable rootstocks, nurturing high quality seedlings is the primary task of developing hawthorn production. Hawthorn breeding more difficult, in recent years has made some experiences around. Hainan southeast hawthorn nursery experience now introduced below. First, the choice of rootstock and the use of different types of hawthorn rootstocks, after grafting on the impact of different trees. Such as the use of hawthorn grafted in Hubei, tree tall, vigorous growth, long life expectancy; grafted wild hawthorn tree low, the results early. Local stator with Hill, Du pear, Begonia for rootstocks are not doing well. Survival rate reached 75% in the same year after grafting with a mountain stator, followed by a growth of 80-100 cm in the following year, and the phenomenon of self-decaying death occurred in the third year. because
