腐熟秸秆对植烟土壤理化性质和酶活性的影响
Influence of Rotten Straw on Physical and Chemical Properties and Enzyme Acitivity of Soil
摘要
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. At30 d, cellulase activity reached the maximum value, the cellulase activities of T2 and T3 increased by 132.67％ and111.83％ 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.关键词
