摘　　要：为了研究缓控释肥与土壤调理剂配施在香蕉上的施用效果,以常规施肥(纯N 600 kg/hm^(2)、P_(2)O_(5)300 kg/hm^(2)、K_(2)O 900 kg/hm^(2))为对照,开展了田间试验(各处理氮、磷、钾养分等量施用),比较了缓控释肥与土壤调理剂配施对香蕉农艺性状、产量、品质和土壤性质的影响。结果表明,缓控释肥与土壤调理剂配施可以改善香蕉农艺性状,提高香蕉产量(比常规施肥增产3.6%~10.5%)和品质,在降低土壤容重以及提高土壤pH值、土壤有效磷含量、阳离子交换量方面效果明显。综合试验结果可知,缓控释肥2(30-6-15)和土壤调理剂3(CaO≥20%,MgO≥3%,SiO_(2)≥6%,pH值9)配施在香蕉上施用效果最好。In order to study the effect of combined application of controlled-release fertilizer and soil conditioner on banana,the field trial(nitrogen,phosphorus and potassium were applied equally in each treatment)was conducted with conventional fertilization(pure N 600 kg/hm^(2),P_(2)O_(5)300 kg/hm^(2),K_(2)O 900 kg/hm^(2))as the control,to compare the effects of different controlled-release fertilizers combined with soil conditioners on agronomic traits,yield,quality of banana and soil properties.The results showed that the combined application of controlled-release fertilizer and soil conditioner could improve the agronomic traits of banana,increase the yield of banana(3.6%-10.5%higher than that of conventional fertilization),improve the quality of banana,and achieve significant effects in reducing soil bulk density,increasing soil pH value,soil available phosphorus content and cation exchange capacity.According to the comprehensive test results,the combined application of controlled-release fertilizer 2(30-6-15)and soil conditioner 3(CaO≥20%,MgO≥3%,SiO_(2)≥6%,pH=9)had the best application effect on banana.
