我省的甘薯主要种植于关中的渭北旱原,陕南的丘陵早地。干旱是影响甘薯生产的主要问题。以往种植的品种以胜利百号为主,其次为农林4号。这两个品种耐旱性均差,在干旱年份,亩产仅一、二千斤,产量甚低,影响着我省甘薯产量的提高。毛主席教导我们:“推广优良品种。”为了选育抗旱、耐瘠适于我省栽培的甘薯新品种,我院通过品种间杂交和选择培育,已育成耐旱、耐瘠薄土壤、耐贮藏的甘薯新品种陕薯1号。经过几年在关中、陕南各地试种,产量显著优于原推广品种,薯块品质中等,是适于我省栽培的一个优良品种。一、来源:
The sweet potato in our province is mainly planted in Weibei dryland in Guanzhong and hilly area in southern Shaanxi. Drought is the main issue affecting sweet potato production. The varieties cultivated in the past are dominated by Victory 100, followed by Agriculture and Forestry 4. Both varieties of drought tolerance are poor, in dry years, only one or two kilograms per mu yield is very low, affecting sweet potato production in our province. Chairman Mao taught us: “Promote fine varieties.” In order to breed new varieties of sweet potato cultivated in drought-resistant and barren-tolerant areas in our province, our institute has developed drought-tolerant and barren-tolerant soils by breeding and selecting cultivars. A new sweet potato variety After a few years in Guanzhong, southern Shaanxi tryout, the yield was significantly better than the original promotion of varieties, medium quality potato, is suitable for cultivation of our province an excellent variety.
