摘　　要：通过多年核桃选育和栽培技术研究,选育出了一个极短枝薄壳核桃PH-528优良品系,表现出极短枝、节间短(平均2.7 cm),极显著地短于对照品种辽河1号和香玲;单果重(13.9 g)显著地大于对照品种;其他经济形状均优于对照品种。同时,总结了一套核桃矮化密植栽培模式,即:建园选址,选择优良品种,合理密植栽培,整形修剪,科学施肥,主要病虫害防治,适时采收。为此,提出了建议:黄河故道区发展种植该优良品系,采取矮化密植栽培模式。Through years of research on walnut breeding and cultivation techniques,an excellent line of extremely short-branched and thin-shelled walnut PH-528 has been bred,showing extremely short branches and short internodes(average 2.7cm),which is significantly shorter than that of the control variety Liaohe No.1 and Xiangling;Fruit weight(13.9g)was significantly higher than that of control varieties.Other economic shapes were better than the control varieties.At the same time,a set of cultivation mode of walnut dwarf and dense planting was summarized.That is,the site selection of the garden should select good products.Reasonable dense planting should be cultivated to shape pruning,scientifically fertilize,control main disease and insect pests and timely harvest.It is suggested that this excellent strain should be developed and planted in the old Yellow River areas,and the dwarf and dense planting mode should be adopted.
