摘要 In order to explore the method of returning corn stalk into field, the effects of returning corn stalk direcfly into soil and applying corn stalk-composted orgar^c fertilizer into soil on the physiochemical properties of tobacco-growing soil were studied. The results showed that returning corn stalk into soil could reduce soil bulk density and increase soil porosity, so as to improve the water and fertilizer retention capacity of tobacco-growing soil. At the same time, returning corn stalk into soil could also increase the organic matter, available phosphorus and available potassi- um contents in tobacco-growing soil. In the early field growth stage of tobacco, soil alkali-hydrolyzable nitrogen content decreased slightly; but in the middle and later field growth stage, the alkali-hydrolyzable nitrogen content in tobacco-growing soil increased. The treatment effect of corn stalk+urea+fermentation bacteria and corn stalk+urea+BM was better than that of the control (returning corn stalk directly into soil), indicating that the corn stalk-composted organic fertilizer had certain popular- ization value. 为探索玉米秸秆还田的方法,研究了玉米秸秆直接还田和添加促腐剂堆制有机肥后还田对植烟土壤理化性状的影响。结果表明,玉米秸秆还田可降低植烟土壤容重,增加植烟土壤孔隙度,从而提高植烟土壤的保水保肥能力。与此同时,玉米秸秆还田还可提高植烟土壤有机质、有效磷和速效钾含量。在烤烟大田生长前期,土壤碱解氮含量略有下降,但到烤烟大田生长中、后期,植烟土壤碱解氮含量有所增加。以玉米秸秆+尿素+发酵菌曲堆制有机肥、玉米秸秆+尿素+BM有机物料腐熟剂堆制有机肥的两个处理效果优于玉米秸秆直接还田,具有推广价值。
