ABSTRACT
In order to solve the problem of chemical fertilizer application balance
of Pu’er tea in Taiwan, the effects of different fertilization treatments on
land nutrient migration and tea quality were explored, and the basis for
rational fertilization of tea gardens was provided. In this study, the effects
of different fertilization treatments on tea quality indexes were studied by
three different sets of fertilization treatments in tea gardens. Three
sets of different fertilization treatments
were set up in the experiment: conventional fertilization treatment (T1),
slow-release fertilizer reduction by 20% (T2) and slow-release fertilizer
reduction by 30% (T3), and the quality index of tea under different
fertilization treatments, as well as the alkaline nitrogen, available
phosphorus and total nitrogen and total phosphorus content in surface water of
the soil were measured and analyzed. The results showed that: 1) compared with
T1, the soil available phosphorus in T3 decreased by 23.5%, and the
alkalinelyzed nitrogen increased by 20.5%; 2) compared
with T1, the total nitrogen and total phosphorus concentrations of surface
water in the T2 and T3 treatments were at a low level compared with T1;
compared with T1, T2 decreased by 71.4%, and
T3 decreased by 68.6%; 3) compared with T1, T3 was able to maintain the quality indicators of amino acids, tea polyphenols and
soluble sugars in tea in a high and stable range. Therefore, under the
condition of conventional fertilization and reduction, a 30% reduction in
slow-release fertilizer is currently more suitable for the fertilization
technology of Menghai County Tea Garden.
