| 摘 要： | 以湖北利川多叶花魔芋为供试材料,在湖北利川市主要魔芋产区开展＂3414＂肥效试验,初步研究了不同肥料配比对多叶花魔芋产量的影响,拟合建立了产量三元二次和一元二次肥料效应回归方程。结果表明,氮磷钾配施能显著提高魔芋产量,但过量施肥会导致魔芋减产,其中磷肥减产显著,对氮钾肥表现有一定的耐受性;在该试验土壤条件下,推荐施肥量为纯氮354kg/hm2,P2O534.5kg/hm2,K2O51kg/hm2,最佳经济产量是11446.5kg/hm2。

| Abstract: | Based on the 3414 fertilizer effect experiment in Lichuan city,the effects of N,P and K fertilizer on Amorphophallus konjac were studied;different fertilizer models(three-factor model and one-factor model) were built.The results showed that balanced fertilization effectively increase the yield of konjac,excessive fertilization especially P lead to low yield.According to experimental soil properties,the balance fertilizer rate was as follows:N fertilizer 354 kg/hm2,P2O5 fertilizer 34.5 kg/hm2,and K2O fertili... |
