摘要:

以‘香荷芋’为供试材料,于泰州、泰兴分别设置T1、T2和T3共3种有机肥用量和CK(对照)处理,探索有机肥施用对芋头生长、食味品质及土壤养分的影响,以期为泰州地区芋头科学施肥技术提供依据。结果表明:泰州、泰兴点T2和T3处理6叶期、12叶期株高均显著高于CK处理(P<0.05),泰兴点T1处理株高在12叶期显著高于CK处理,在6叶期和泰州点6叶期、12叶期与CK处理均无显著差异;泰兴点T3处理6叶期叶面积指数平均为0.31,均显著高于其他处理,其他处理间差异均不显著,泰州、泰兴点T3处理12叶期叶面积指数分别为0.71、0.75,均显著高于CK处理;有机肥用量与子芋口感、香味指标及土壤有机质含量均呈显著正相关,相关系数分别为0.89、0.86、0.79;泰州、泰兴点T2、T3处理碱解氮、有效磷均显著高于CK处理;泰州点土壤有效钾以T2处理最高,为174 mg/kg,T3处理最低,为159 mg/kg,泰兴点则以CK处理最高,为172 mg/kg,T3处理最低,为140 mg/kg。

Abstract:

A total of three organic fertilizer application amounts, T1-T3 and CK (control) were set up in Taizhou and Taixing to explore the influence of organic fertilizer application on the growth and development, eating quality and soil nutrients of taro, respectively, aiming to provide a basis for scientific fertilization on taro. The results showed that plant height at the 6th and 12th leaf stages of T2 and T3 was significantly higher than that of CK in Taizhou and Taixing (P<0.05), the plant height of T1 was only significantly higher than that of CK at the 12th leaf stage in Taixing, and there was no significant difference at the 6th and 12th leaf stage between T1 and CK in Taizhou. The average leaf area index (LAI) at the 6th leaf stage of T3 was 0.31 in Taixing, which was significantly higher than that of other treatments, and the difference of LAI among other treatments was not significant. The LAI at the 12th leaf stage of T3 was 0.71 and 0.75 in Taizhou and Taixing, respectively, which were significantly higher than that of CK. The application amount of organic fertilizer was significantly and positively correlated with the taste, fragrance index and soil organic matter, with the correlation coefficient of 0.89, 0.86 and 0.79, respectively. The alkaline nitrogen and available phosphorus of T2 and T3 were significantly higher than those of CK. The maximum and minimum amount of available potassium in soil was 174 mg/kg (T2) and 159 mg/kg (T3) in Taizhou, respectively, while in Taixing, the maximum was found in CK of 172 mg/kg, and the minimum was found in T3 of 140 mg/kg.
