在秦岭北麓无灌溉的旱塬坡地条件下,1974年定植的5.55亩乔砧秦冠密植园(行株距2.5×1.5米),栽后第三年亩产604.5公斤,第8～11年,亩产2636.2～3617.8公斤,11年平均亩产1703.5公斤,一、二级果率在90%以上,平均单果重150克左右.经济效益显著,栽后第三年收回投资并有盈余,10年平均每亩纯收入847.40元,近两年每亩纯收入在2000元以上.试验总结出采用良种壮苗、密植小冠和精细管理等关键措施,使树体得到一定控制,可供旱塬坡地乔砧苹果密植丰产参考应用.
Under the condition of irrigated dryland on the northern foot of Qinling Mountains, 5.55 mu of Qiaoqin Qin Guan densely planted plant (row spacing 2.5 × 1.5 m) was planted in 1974, and 604.5 kg per mu in the third year after planting. In the 8th to 11th year, 2636.2 ~ 3617.8 kilograms of mu per mu, average output of 1703.5 kilograms per mu in 11 years, more than 90% of primary and secondary fruits, average fruit weight about 150 grams, remarkable economic benefits, investment recovery and surplus in the third year after planting, 10 years The average net income per mu is 847.40 yuan, the net income per mu is more than 2000 yuan in recent two years.The experiment summed up the key measures such as planting strong seedlings, planting small crowns and fine management so that the tree can be controlled, Joe anvil apple dense planting high yield reference application.
