新疆早实核桃集约栽培试验初报

Intensive Horticultural Trial with Early Xinjiang Walnut Cultivars

本文基于新疆早实核桃集约栽培试验的第一阶段(前5年)试验结果:定植(嫁接)后第5年平均亩产核桃63kg(最高株产8.34kg),间种产值1254元,经济效益达1886.6元;5年间平均亩年产核桃19.37kg,间种产值684.2元,经济效益达877.9元,初步提出了适宜早实核桃园式集约栽培的前期品种选择、搭配,载植密度,间种方式、施肥浇水及幼树整形修剪等一整套树体和田间管理技术措施,对新疆乃至全国核桃生产具有一定指导作用。

This article presents a report of the first phase (the first 5 years) of the trial. The preliminary results come as follows. The early walnut cultivars used included 'Wen-185', 'Xinzaofeng', and 'Xinxin-2'. At the fifth year after transplanting/grafting, the average walnut yield reached 945 kg per ha, with the maximum yield for individual trees being 8.34 kg. Intercropping with peach trees, cash crops and/or fruit seedlings brought in another RMB 18 810 yuan per ha. This has proved to be a good story of success, on the basis of which a proper design for this type of intensive early walnut orchards is proposed in terms of cultivar selection, pollination cultivar layout, planting density, intercropping species and patterns, and post-planting care.
