摘要
为给合浦薯农木薯品种选择和施肥提供科学依据,开展了不同木薯品种和施肥水平对木薯鲜薯产量、淀粉含量和淀粉产量影响的研究。结果表明,‘GR5’‘南植199’‘GR3’极其适合在合浦县推广种植,‘GR911’‘SC5’较适合种植;对于贫瘠土地或资金有限的薯农,推荐种植‘GR5’‘GR911’‘SC5’;对大部分木薯品种,施肥能极显著提高鲜薯产量和淀粉产量,极显著降低淀粉含量;对耐贫瘠品种‘GR911’,施肥不增产,且降低淀粉含量和产量。
In order to provide scientific basis for cassava variety selection and fertilization for Hepu cassava farmers,different cassava varieties and fertilization effect on fresh root yield,starch content and starch yield were studied.The results showed that’GR5’’Nanzhi 199’and’GR3’were very suitable for planting in Hepu County,and’GR911’’SC5’were more suitable for planting;For cassava farmers with poor land or limited funds,’GR5’’GR911’’SC5’is recommended to plant;For most cassava varieties,fertilization can significantly increase the fresh root yield and starch yield,and significantly reduce the starch content;For the barren tolerant variety’GR911’,fertilization does not increase yield,and even reduces starch content and yield.
