摘要: 【目的】探讨缓释控肥施用在芋头种植中的应用效果。【方法】以靖江香沙芋为试验材料,设置45%速效复合肥(F1)和47%缓释控肥(F2)2种肥料,315 kg/hm2(Y1),360 kg/hm2(Y2),405 kg/hm2(Y3),450 kg/hm2(Y4)共4种肥料用量,研究对芋头主要农艺性状、产量及经济效益的影响。【结果】2种肥料6月13日、7月13日平均株高、茎粗、叶长和叶宽均随施肥量增加而增大,8月13日、9月13日则无显著差异(P<0.05)。其中,F1各处理6月13日主要农艺性状均高于F2对应各处理,在7月13日则低于F2。总体上2种肥料用量对芋头叶片叶绿素含量(SPAD)均无显著影响。45%速效复合肥和47%缓释控肥子孙芋产量变幅分别为13 735.20~14 245.80 kg/hm2和13 927.35~14 843.70 kg/hm2,其用量和子孙芋产量相关系数分别为0.228、0.352,均未达到显著水平。47%缓释控肥各处理经济效益均高于45%速效复合肥对应各处理。【结论】缓释控肥与速效复合肥相比具有肥效持续时间久、产量和经济效益高等优点,建议其用量不低于315 kg/hm2

Abstract: 【Objective】To explore the application effect of slow-release controlled fertilizer reduction on taro [Colocasia esculenta (L.) Schoot].【Methods】Jingjiang Xiangsha taro was used as the test material. Two fertilizers, 45% quick-acting compound fertilizer (F1) and 47% slow-release controlled fertilizer (F2), including 315 kg/hm2 (Y1), 360 kg/hm2 (Y2), 405 kg/hm2 (Y3) and 450 kg/hm2 (Y4), were set to study their effects on main agronomic traits, yield and economic benefits of taro.【Results】The average plant height, stem diameter, leaf length and leaf width increased with the increase of fertilizer amount on June 13 and July 13, but there was no significant difference on August 13 and September 13 (P<0.05).Among them, the main agronomic traits of F1 in each treatment were higher than F2 corresponding to each treatment on June 13, and lower than F2 on July 13, no significant effect on the chlorophyll content (SPAD) of taro leaves by the two fertilizers. The yield variations of seed taro with 45% quick-acting compound fertilizer and 47% slow release controlled fertilizer were 13 735.20 -14 245.80 kg/hm2 and 13 927.35-14 843.70 kg/hm2, respectively. The correlation coefficients of the amount and seed taro yield were 0.228 and 0.352, respectively, which did not reach the significant level. The economic benefit of each treatment of slow release controlled fertilizer was higher than that of each treatment of 45% quick effect compound fertilizer.【Conclusion】Compared with quick-acting compound fertilizer, slow-release controlled fertilizer had the advantages of long duration of fertilizer effect, high yield and economic benefit and recommend slow-release controlled fertilizer 315 kg/hm2 at least.
