摘要:

为缓解长期单施化肥对茶园土壤肥力带来的不良影响,提升茶叶产量和品质,在六安瓜片茶园开展连续2年的田间试验,研究菜籽饼肥、秸秆有机肥、猪粪有机肥、牛粪有机肥、沼渣有机肥、生物有机肥分别与化肥配施(有机肥替代70%的养分)对茶叶生长、品质和土壤肥力的影响。结果表明,与纯施化肥的CK相比,秸秆有机肥配施化肥下,茶树的百芽质量和芽茶密度显著(P<0.05)增加,且增幅最大,其次是猪粪有机肥。从茶叶内含成分(茶多酚、游离氨基酸、酚氨比、咖啡碱、水浸出物)判断,秸秆有机肥、猪粪有机肥和生物有机肥的效果较好。秸秆有机肥和猪粪有机肥对茶园土壤理化性状的提升效果较好,土壤养分含量和酶活性明显提高。综合2年试验结果,秸秆有机肥配施化肥促进茶树生长、改善茶叶品质、提升土壤肥力的效果最好。

Abstract:

In order to alleviate the adverse effects of long-term single application of chemical fertilizer on tea garden soil,and improve the yield and quality of tea, a field experiment was carried out in Lu’an Guapian tea garden for two consecutive years to study the effects of organic fertilizers made from rapeseed cake, straw, pig manure, cow manure, biogas residue, biomass (denoted as RCO, SO, PO, CO, BRO, BO, respectively) combined with chemical fertilizer (70% nutrient substituted by organic fertilizer)on tea growth, quality and soil fertility.The results showed that SO or PO combined with chemical fertilizer significantly (P<0.05) increased the 100-bud weight and bud density of tea as compared with the control (CK, all nutrients were input by chemical fertilizer). For chemical components of tea (tea polyphenol, free amino acid, ratio of phenol to amino acid, caffeine, aqueous extract), the highest contents were recoreded when SO or PO or BO was applied with chemical fertilizer. SO or PO application coupled with chemical fertilizer could improve soil fertility, as the nutrients contents and soil enzymes activities were elevated. Given the 2-year results, application of SO and chemical fertilizers had the best effect on promoting tea plant growth, improving tea quality and soil fertility under the experiment conditoins.

Key words: organic fertilizer, tea, Lu’an Guapian, growth, quality, soil fertility
