原平市同川,是山西省最大的产梨区,已有1500多年的栽培历史,因此老龄梨树居多。为使老龄梨树更新复壮,经过对4万多亩低产老龄梨树进行的一系列技术改良研究,以去头换优效果最好。现在换成酥梨、鸭梨、雪花梨等优良品种,已挂果的有7万多株,年产800多万公斤,增加收入1360万多元。去头换优的具体技术是: 一、梨树接穗的冬采与贮藏。同
Yuanping City Tongchuan, is the largest pear-producing area in Shanxi Province, has 1500 years of cultivation history, so most elderly pears. In order to rejuvenate the aged pear tree, after a series of technical improvement studies on more than 40,000 mu of low-yielding aged pear trees, it is best to go head to head for optimization. Now replaced by pear, pear, snow pear and other fine varieties, fruit has more than 70,000 strains, with an annual output of more than 800 million kilograms, an increase of more than 13.6 million yuan. Specific technology to devaluation is: First, the winter harvest and storage of pear scion. with
