脱毒甘薯—商薯19钾肥施用量效果分析

为探讨脱毒甘薯—商薯19最佳钾肥施用量,通过固定氮﹑磷肥用量,以钾肥为变量,进行了单因子随机区组试验,结果表明,随钾肥施用量的增加,延长了薯块迅速膨大期天数,增加了光合产物的积累,提高了产量,以施氧化钾16/667m2产量为最高。

To explore the virus-free sweet potato - the best 19 companies potash potato fertilizer, through a fixed amount of nitrogen , phosphate to potash fertilizer as a variable, for a single-factor randomized block experiment results show that with the increase in the amount of potash fertilizer, extend- ing Shukuai rapidly expanding period of days, increasing the accumulation of photosynthetic products, increase production, to Shi hydroxide 16/667 m yield the highest.
