“桃三杏四梨五年,要吃苹果七、八年”.这是广大群众过去栽培果树的经验总结,说明苹果是结果较晚的果树树种.近几年来,各地虽对苹果树正形修剪技术有所改进,加强了栽培管理,但还得三、四年才能结果.我所1977年3月,定植1.7亩高密度苹果试验园,最高密度行距一米,株距60厘米,每亩栽1111株.定植当 “Peach apricot four pears for five years, seven or eight years to eat apples.” This is the vast majority of past experience in the cultivation of fruit trees, indicating that the apple is the result of late fruit tree species in recent years, although the apple trees are shaped Pruning technology has improved and strengthened the cultivation and management, but still have three or four years to the results of our 1977 March, planting 1.7 acres of high-density apple test garden, the highest density of one meter spacing, spacing 60 cm, planted per acre 1111 plants
