摘要/Abstract

摘要： 为探究施用腐熟秸秆对植烟土壤理化性质和酶活性的影响，采用田间试验研究了不同梯度腐熟秸秆对植烟土壤容重、含水率、速效养分、酶活性的影响。结果表明：①腐熟秸秆对降低土壤容重，提高含水率具有显著作用。在移栽后30 d，T3土壤容重达到最低值1.07 g/cm3，比对照降低了13.01%。②随着腐熟秸秆施用量的增加，植烟土壤碱解氮、速效磷、速效钾的供应量显著提高，其中T2、T3效果显著优于对照。③腐熟秸秆可以提高植烟土壤脲酶、纤维素酶、蔗糖酶、过氧化氢酶活性。在45 d，土壤脲酶活性达到最大值，T2、T3脲酶活性分别比对照提高了26.29%、21.86%；在30 d，纤维素酶活性都达到最大值，T2、T3纤维素酶活性分别比对照提高了132.67%、111.83%；在60 d，土壤蔗糖酶活性达到最大值，T3土壤蔗糖酶活性比对照提高了29.23%；在45 d，土壤过氧化氢酶活性达到最大值，T3土壤过氧化氢酶活性比对照提高了25.71%。综合来看，施用腐熟秸杆对改善植烟土壤理化性质、提高土壤肥力、增强土壤酶活性有积极作用，T3（11 250 kg/hm2）可以作为河南烟区腐熟秸秆参考量。

Abstract: In order to explore the influence of rotten straw on soil physical and chemical properties and enzyme activity, this paper studied the effects of rotten straw with different gradients on volume-weight, moisture content, available nutrient and enzyme activity of tobacco-planting soil by field experiments. The results showed that: ① Rotten straw had remarkable effects on decreasing soil volume-weight and increasing soil moisture content. At 30 d after transplanting, soil volume-weight of T3 treatment reached the lowest value of 1.07 g/cm3, 13.01% lower than that of the contrast. ② With the increasing of rotten straw dosage, the supply of alkali-hydrolysable, available phosphorus, available potassium in tobacco-planting soil were significantly increased. Among them, the effects of T2 and T3 were espcially better than that of the contrast. ③ Rotten straw could improve the activities of urease, cellulase, sucrase, catalase of tobacco-planting soil. At 45 d, the soil urease activity reached the maximum value, and the urease activities of T2 and T3 increased by 26.29% and 21.86% than that of the contrast, respectively. At 30 d, cellulase activity reached the maximum value, the cellulase activities of T2 and T3 increased by 132.67% and 111.83% than that of the contrast, respectively. At 60 d, the soil sucrase activity reached the maximum value, and soil sucrase activity of T3 increased by 29.23% than that of the contrast. At 45 d, the soil catalase activity reached the maximum value, and soil catalase activity of T3 increased by 25.71% than that of the contrast. Taken together, applying rotten straw was helpful for improving physical and chemical properties, increasing soil fertility and strengthening enzyme activity of tobacco-planted soil. T3 (11 250 kg/hm2) clould be used as a reference quantity of rotten straw in tobacco-growing areas of Henan province.
