摘要
进行了2个木薯品种、5个施肥位置的裂区试验,结果发现:在茎基部、茎基顶中间和茎侧中间施肥,木薯的鲜薯产量比茎侧施肥(CK)提高10.2%～17.3%,鲜薯淀粉产量比CK提高12.7%～19.0%。因此宜在种茎基部至茎基顶中间之间,即离茎基部15～30cm处定点施肥;对木薯苗施肥时,可在茎基顶中间或茎侧中间施肥。
The effects of five different fertilization places on the yield and growth of two cassava varieties were researched through spilt-plot experiments in Hainan island in 2008.The results showed that in comparison with CK(fertilization at the 15-20 cm distant site nearby one side of cassava seed-stem),fertilization at the 15-30 cm distant site nearby the base of cassava seed-stem or at the 40 cm distant site nearby one side of cassava seed-stem could increase the fresh root yield and fresh starch yield of cassava by 10.2%-17.3% and 12.7%-19.0% respectively.Therefore,it is suitable for cassava to apply the fertilizer at the 15-30 cm distant site nearby the base of the planted seed-stems.For the seedlings of cassava,it is proper to apply the fertilizer at the 30 cm distant site nearby the base of cassava seed-stem or at the 40 cm distant site nearby one side of cassava seed-stem.
