秸秆还田在植烟土壤性状改良上应用的研究进展

为提高烤烟品质,利用作物秸秆还田改良土壤理化性质从而改善烟叶品质是当前烟区的研究热点。农作物秸秆是一种重要的农业资源,秸秆还田也是有效利用秸秆资源和提高农业经济效益的重要途径,秸秆还田能明显改善土壤的理化性状,提高土壤肥力和蓄水保墒能力、增加土壤养分和有机质含量以及微生物的数量,还可以减少焚烧秸秆带来的环境污染,是保证粮食作物高产稳产的有效措施之一,又是保护农村生态环境的一项重要技术。笔者就秸秆对植烟土壤性状改良的原理、研究现状及关键技术作一阐述和分析,为更好地合理利用秸秆资源,发挥秸秆资源在农业可持续发展中的潜力提供理论依据和技术支撑。

research progress on Application of Improving Tobacco Soil Fertility by Reusing of Crop Straws

In order to improve the quality of Tobacco, reusing of Crop Straw is one of the important technical methods to enhance the quality of Tobacco. Crop straws are the important agricultural resource, and reusing of crop straws is the important way which enhances agriculture economy and availably utilizes sources. Reusing of crop straws is one of the effective measures which could obviously improve soil physical and chemic character, advance soil fertility and capability of keeping water and moisture content, increase soil content of nutrient, organic matter and animalcule, as well as, reduce environmental pollution which caused by burning crop straws, assure high and steady product of foodstuff, and is a new technique which could protect ecological environment in country. The researcher roundly expatiated and analyzed the principium, actuality and technique for improving tobacco soil fertility with reusing of crop straws in order to provide technical service and academic gist for tenet that the rational reusing of crop straws could hasten continuable agriculture development.
