| 中文摘要: |
| 选取皖北地区5 种典型的果农复合模式即苹果+银杏苗P*Y苹果+石榴苗P*S苹果+桃苗P*T
苹果+白术P*B苹果+辣根P*L以纯林模式为对照，对不同模式土壤酶活性的特征进行研究结果表明与纯林
模式相比，不同果农复合模式土壤酶活性均有所提升，其中以P*Y，P*B 两种模式效果最好，不同模式土壤酶活性具
有明显的空间分布特征，土壤蔗糖酶、脲酶及蛋白酶活性均随土层深度的加深呈不断降低的趋势，过氧化氢酶活性
则随土层深度的加深不断升高，土壤酶活性具有明显的季节特征，其中蔗糖酶、脲酶及蛋白酶均在夏季活性最高过
氧化氢酶活性最大值则出现在秋季。 |
| 英文摘要: |
| 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. |
