| 摘 要： | 通过大田试验系统研究了控释掺混肥（crf）对大蒜根际土壤酶活性的影响。结果显示土壤酶活性（土壤脲酶、磷酸酶、蔗糖酶和过氧化氢酶）随控释掺混肥施入量的增加而显著提高,等量（crf1）和80%用量（crf2）处理脲酶、磷酸酶和蔗糖酶活性均显著高于普通施肥（ccf）处理,表明控释掺混肥可通过增强土壤酶活性来提高土壤速效养分含量,进而提高大蒜鳞茎产量。

| Abstract: | The effects of the controlled release bulk blending fertilizer(CRF) on the garlic rhizosphere soil enzyme activity were investigated by the field trial.The results showed that the activities of urease,phosphatase,sucrase and catalase increased significantly with the increasing application amount of CRF,and the activities of urease,phosphatase and sucrase of 100% and 80% CRF treatments were significantly higher than those of CCF treatment,which indicated that CRF could increase the soil soluble nutrient cont... |
