甘薯施肥与栽插试验研究

Fertilizer Application and Cuttage of Sweet Potato

试验结果表明 ,施用三元复合肥倒插的甘薯产量最高。无论正插或倒插 ,施用“大兴牌”三元复合肥的甘薯产量都显著地高于农民习惯施肥法 ,而甘薯倒插与正插的产量无显著差异。甘薯施用“大兴牌”三元复合肥 ,苗架长势好 ,分枝多 ,块根膨大快 。

The results show that the sweet potato yield of reversed cuttage and applying three element compound fertilizer is the best, whether normal cuttage or reversed cuttage, the yield of applying three element compound fertilizer is higher than those of the traditional application and that in yield there is no significant difference between the reversed cuttage and the normal whether applying three element compound fertilizer and traditional application. The sweet potato of applying three element compound fertilizer is possessed of better seedings, much branched, bigger tuber and strong resistance to disease and pests.
