【摘要】 为研究优质食用型甘薯品种“龙薯35号”的配套施肥技术，采用正交试验方法，研究有机肥、复合肥、施肥方式3个因素对该品种产量的影响。结果表明，有机肥、复合肥、施肥方式对甘薯产量有极显著影响，增施有机肥和复合肥，采用一次性追肥的方式能提高甘薯产量，在中高地力水平条件下，施用有机肥3 900 kg/hm~2、复合肥600 kg/hm~2、肥料作为追肥一次性施用能取得较高的产量和社会经济效益。更多还原

【Abstract】 In order to study the matching fertilization technology of high-quality edible sweet potato variety ‘Longshu 35’, the orthogonal test method was used to study the effects of three factors(manure, compound fertilizer and fertilization method), on the yield of this variety. The test results showed that manure, compound fertilizer and fertilization method had a very significant impact on the yield of sweet potato. Increasing the application of manure and compound fertilizer and using one-time topdressing could improve the yield of sweet potato. Under the condition of medium high soil fertility, the application of manure 3 900 kg/hm~2, compound fertilizer 600 kg/hm~2, and one-time application of fertilizer as topdressing could achieve higher yield and social and economic benefits.更多还原
