上个世纪80年代和90年代初苹果大发展时期,山东省主要推广的是乔砧密植栽培模式,90%以上的果园是按照此栽培模式建立的。此种栽培模式虽然对推动苹果产业快速发展作出了贡献,但由于乔砧密植树体控冠和促进结果技术难度大,果农难以掌握,管理费时费工,加上该模式自身的缺陷,致使大多数果园密闭、产量低、果品质量差,已不能适应现代苹果产业发展的需要。
The last century 80’s and early 90’s Apple’s great development period, Shandong Province is the main promotion of Joe anvil planting mode, more than 90% of the orchard is established in accordance with this cultivation mode. Although this mode of cultivation has contributed to the rapid development of the apple industry, it is difficult to control the fruit growers because of the difficult task of controlling the crowns and promoting the results of the tree planting and the time-consuming and labor-intensive management of the fruit trees. As a result, Most orchards airtight, low yield, poor quality of fruit, can no longer meet the needs of the development of modern apple industry.
