| This paper studied the characteristics of soil enzyme activity in different fruit-crop agroforestry patterns. Five
typical fruiter-crop agroforest patterns including Malus+Ginkgo (P*Y), Malus+Punica (P*S), Malus+Prunus (P*T), Malus+
Atractylodes (P*B), and Malus+Cochlearia (P*L), in northern Anhui province were selected and the Malus (CK) was used as
control. The results showed that soil enzyme activities of different fruiter-crop agroforestry patterns were improved than the
Malus (CK)and P*Y and P*B worked best. There was a obvious spatial distribution characteristic in soil enzyme activities of
different fruiter-crop agroforestry patterns. The activities of sucrase, urease, and protease decreased with the increase of soil
layer, while the activity of catalase increased. Meanwhile soil enzyme activities had a seasonal characteristic. The highest
activities of sucrase, urease, and protease appeared in summer while that of catalase was in autumn. |
