1976年在本所栽植行株距为4×2米,共11.45亩的乔砧苹果密植园。栽后当年成花,二年结果,三年投产(平均亩产642公斤),五年丰产(平均亩产2456.7公斤),六年进入盛果期,栽后6～10年平均亩产4250公斤;好果率达98%以上,一级果率在85%以上。栽后五年收回全部投资并有盈余,十年内每亩平均盈余10495.67元。总结出幼树期实现早结果、早丰产,盛果期控制树体扩展的乔砧苹果密植栽培技术体系,并提出了树体丰产结构指标。可供乔砧苹果密植丰产栽培参考应用。
1976 planted in our line spacing 4 × 2 meters, a total of 11.45 acres of Joe anvil apple close plantation. Planting year after flowering, two years results, three years of operation (average yield of 642 kilograms), five years of high yield (average per mu 2456.7 kilograms), six years into the flourishing period, planted 6-10 years average yield 4250 kilograms Good fruit rate of more than 98%, a fruit rate above 85%. Five years after planting, all the investments will be recovered and there will be a surplus. The average earnings per mu within 10 years will be 10,495.67 yuan. Summed up the young tree to achieve early results, early bumper crop, full fruit stage control tree expansion Joe anvil close planting cultivation technology system and put forward the tree structure of high yield indicators. For Joe anvil apple dense planting high yield cultivation reference application.
