- Abstract:
-
Fertilization is an important agricultural measure that improves not only yield and quality, but also soil quality of tea plantation. Thus, a 3-year field orientation experiment was conducted with 6 fertilization regimes CK (control treatment), NPK (inorganic fertilizer), O (organic manure), NPKO (half inorganic fertilizer + half organic manure), NPKL (inorganic fertilizer + leguminous green manure), NPKOL (half inorganic fertilizer + half organic manure + leguminous green manure) to study the effect of fertilization regime on the soil microbial quantity and enzyme activity in rhizosphere of tea. The study was designed to facilitate the selection of reasonable fertilization models. The results showed that:(1) the fertilization regimes increased soil moisture content and conductivity; moreover, these two parameters were the highest in the regime of NPKOL, which decreased in the order:NPKOL > NPKL > O > NPKO > NPK > CK; (2) compared with the control treatment (CK), soil fertility significantly increased (p<0.05), while soil total phosphorus did not significantly increase (p>0.05); (3) the fertilization regimes increased the number of bacteria, number of fungi, number of actinomyces and total number of microorganisms, which decreased in the order:NPKOL > NPKL > O > NPKO > NPK > CK; (4) the fertilization regimes increased soil enzyme activity, which decreased in the order:NPKOL > NPKL > O > NPKO > NPK > CK. It was therefore beneficial to adopt the fertilization regime of half tea formula fertilizer plus half organic fertilizer with legume green manure regime in tea production.
