清原地处辽宁东部山区,野梨资源极为丰寓。据调查推算,全县可以移栽改接的山梨达一百万株。多年来,广大群众和果农,采用就地劈接和高接换头方法,发展了梨果生产,表现为结果早、丰产、抗性强等特点,对发展山区经济,增加副业收益起到一定作用。随着农业现代化发展和要求,果树生产水平不断提高,就地劈接方法显露出不集中、不规整等缺点,做不到旱能灌、涝能排,更不易做到主要作业机械化,实现高标准综合管理。为此,从1970年开始,我们对野生山梨进行了移栽改接试验。目前已移栽近万株,移栽的山梨,小的三年生,大的28年生。从试验结果看,7年生以下的果树,由于树小,产量上的慢;16年生以上的果树,根系大,起树搬运定
Qingyuan is located in the eastern mountains of Liaoning, wild pear resources extremely rich flat. According to the investigation and calculation, the county can be transplanted into the Yamanashi up to one million. Over the years, the majority of the masses and fruit growers have adopted the method of on-site split and high pick-up to develop the production of pear and fruit with the characteristics of early results, high yield and strong resistance, which have certain effects on developing mountain economy and increasing sideline revenue effect. With the development and requirements of agricultural modernization, the production level of fruit trees has been continuously improved. The in-situ splitting methods have revealed the shortcomings of lack of concentration and irregularity, failing to dry irrigation and waterlogging, making it more difficult to mechanize main operations and achieve high Standard integrated management. To this end, since 1970, we have wild sorrel transplants to connect the test. Nearly 10,000 transplants have been transplanted, transplanted Yamanashi, a small three-year-old, a large 28-year-old. From the test results, fruit trees below 7 years old, due to small trees, slow production; fruit trees more than 16 years old, large roots, tree handling set
