我们从1971年开始先后在农科所、景宁林场水果队、县良种场、沙溪公社贵溪大队等将低产的老品种梨树采用“多头高接”,一般高接后第二年开始结果,也有的当年就结果。如贵溪大队去年二月高接了四株,今年平均株产29斤,未接的平均株产仅4斤;又如县农科所果园,十年生的大梨树原来总产仅100～200斤,1972年嫁接后,今年就收到4000多斤,高的单株70斤,估计明年能超过万斤,单株可达100斤。高接换种方法:我县近年都采用枝接,在一月下旬至三月五日前(以二月下旬为最适期)除刮西北风、
We began in 1971 in the Agricultural Science Institute, Jingning Forest Fruit Team, County Seed Farm, Shaxi commune Guixi Brigade and other low-yielding varieties of pear used “long high pick”, generally high then the second year Results, and some results in the year. For example, Guixi Brigade took four high plants in February last year, with an average of 29 kilograms produced this year. The average yield of unaccounted crops is only 4 kilos. Another example is that the total output of perennial pear trees in the county agricultural institutes is only 100 ~ 200 pounds, grafted in 1972, this year received 4000 kilos, 70 kilograms of tall plants, it is estimated that next year can exceed 10,000 pounds, up to 100 pounds per plant. High exchange method: My county in recent years have adopted the stick, in late January to March 5 (in late February for the most appropriate period) in addition to scratch the northwest wind,
