我省东北部山区有丰富的野生山里红资源,这些资源过去管理得不好,利用的比较差,几乎处于荒废状态。利用山里红嫁接山楂,发展山楂生产,投资少,见效快,是变废为宝的好方法。山里红嫁接山楂,叶采用切接法,多在“清明”至“谷雨”期间进行。适用于较细的砧木。嫁接时先将山里红距地面5厘米处剪断,在迎风方向平直光滑处,从横切面上约1/4~1/5处垂直切下,切口深2~3厘米,再将健壮、优质、无病虫的接穗,从下端没有芽的一面用刀削成2.5厘米左右的长
Mountainous areas in the northeastern part of our province are rich in resources of wild mountain red mountains. These resources were poorly managed in the past and were in poor use and almost in a state of wasted. The use of red grafted hawthorn in the mountains, the development of hawthorn production, less investment, quick, is a good way to turning waste into treasure. Red grafted hawthorn in the mountains, leaves with cut the law, mostly in the “clear” to “valley rain” during. For thin rootstocks. When the first red grafted mountain 5 cm from the ground at the cut straight in the wind direction smooth, from the cross-section of about 1/4 ~ 1/5 vertical cut, incision depth of 2 to 3 cm, and then robust, high quality, Insect-free scion, from the bottom without bud side with a knife into about 2.5 cm long
