| 中文摘要: |
| 针对香蕉生产中大量施用化肥和偏施氮肥导致蕉园土壤养分有效性低、土壤质量退化等问题。
以“巴西蕉”为试材，在投入养分量相同的条件下，研究添加不同用量木本泥炭及其衍生品腐植酸钾肥
对香蕉产量、品质及土壤养分的影响。结果表明：添加木本泥炭（7 500 kg/hm2）和腐殖酸钾肥（3 750 kg/
hm2）处理较推荐施肥处理分别增产12.62% 和15.39%，差异达显著水平，且蕉果可溶性总糖和可溶性固形
物含量提高，品质改善。与推荐施肥处理相比，添加木本泥炭及腐殖酸钾肥处理收获期土壤60～90 cm 土层
硝态氮含量显著降低，其中木本泥炭用量3 750、7 500 kg/hm2 处理分别降低44% 和45%，腐殖酸钾肥处理
为53%，减少了硝态氮向环境中迁移的风险；添加木本泥炭或腐殖酸钾肥处理土壤30～90 cm 土层速效钾
含量显著提高。建议在香蕉施肥过程中添加木本泥炭及腐植酸钾肥与化肥配施。 |
| 英文摘要: |
| To solve the reduction of available nutrient and soil deterioration under conventional fertilizer
management with over-application of fertilizer especially nitrogen fertilizer in banana plantation，a field trail
was conducted to evaluate the effects of woody peat（ WP） and humic acid（ HAs） on yield and quality of
‘Baxijiao’ under equal chemical pure nutrient input. The results showed that，under equal chemical pure
nutrient input，the yield with WP application at 7 500 kg/hm2 treatment and HAs at 3 750 kg/hm2 increased
significantly by 12.62% and 15.39%，respectively. The contents of soluble sugar and Brix both increased. The
fruit quality was improved. WP application at 3750 kg/hm2 and 7 500 kg/hm2 significantly reduced the NO3
-
content by 44% and 45% in the 60-90 cm soil layer compared with recommended fertilization treatment，and
the HAs treatment reduced more than 53%. Thus，the risk of migration of nitrate to environment was reduced.The available potassium content of WP and HAs treatments improved in the 30-90 cm soil layer compared to
recommended fertilization treatment. The combination of WP，HAs and chemical fertilizer is recommended to
banana plantation. |
