为探索芭蕉芋块茎生长发育规律及主要影响因素，开展了芭蕉芋肥效试验对淀粉积累及产量影响研究，分别在P、K相同、N、K相同、N、P相同的情况下对N、P、K的4个不同水平处理进行随机区组试验。结果表明：株高、分蘖数在7、8、9、10月是芭蕉芋生长最快的季节，10月后，株高生长缓慢，植株分蘖数基本停止，茎径在10～12月增长较快；干片淀粉率、干物率还是鲜芋淀粉含量积累，9～12月是芭蕉芋块茎淀粉积累较快的时期，到2013年3月测产时，无论干片淀粉率、干物率还是鲜芋淀粉含量都有所下降；在N、P、K肥料3要素的筛选试验结果表明：以N 300 kg/hm2、P（ P2 O5）180 kg/hm2、K（ K2 O）240 kg/hm2为最佳组合。

For exploring the growth regularity of Canna edulis tubers and main influencing factors , the author studied the effects of fertilizer ( N, P, K) efficiency test on the tuber starch accumulation and yield of Canna edulis through single-factor randomized block experiment .The results showed that the plant height and tiller number of Canna edulis increased fastest from July to October;after October, the plant height increased slowly , and the tillering stopped basically;the stem diameter grew faster from October to December .The tuber dry matter rate , dry and fresh edulis starch content increased quickly from September to December , but they have decreased to a certain extent in March , 2013.The results of N, P, K fertilizer screening test indicated that the combined ap-plication of N 300 ㎏/hm2 , P ( P2 O5 ) 180 ㎏/hm2 , and K ( K2 O) 240 ㎏/hm2 was the best .
