西北黄土高原是我国最大的苹果优生区,近年来苹果定植面积不断扩大,而从苹果定植到挂果至少需要3~5年时间,在幼龄果园套种粮食等高秆作物,不但效益低,而且影响幼龄果树的正常生长,如何既不影响幼龄果树的正常生长,又能提高土地的产出率和经济效益,一直是困扰广大农民的一大难题。近年来,灵台县农技中心经过试验示范,总结出了幼龄果园套种甜瓜栽培技术,在塬区幼龄果园年种植甜瓜4 500亩左右,平均亩产1 360 kg,亩产值 The Northwest Loess Plateau is China’s largest apple eugenics area. In recent years, the planting area of ​​apple has been expanding constantly. However, it takes at least 3 to 5 years for apple-planting and fruiting to intervene in high-stalk crops such as grain in young orchards, which not only has low benefit but also affects The normal growth of young fruit trees can not affect the normal growth of young fruit trees and increase the yield and economic benefits of land. It has always been a major challenge to peasants. In recent years, Lingtai County Agricultural Technology Center after experiment and demonstration, summed up the young orchard intercropping musk melon cultivation techniques, young orchards in the area of ​​planting 4,500 acres of melon, the average yield of 1 360 kg per mu
