玉米秸秆施用措施对土壤肥力及烤烟产质量的影响
Effects of applying corn stalks on soil fertility, crop yield and quality of flue-cured tobacco
摘要
Abstract
For comparing the effects of carbonization and liming of corn stalks on the promotion of soil fertility, yield and quality of flue-cured tobacco, field experiments were carried out to investigate the influences of different application methods on nutrient content, aggregate quantity, integrated fertility of soil, and consequently the yield and quality of flue-cured tobacco. The results showed that: under conventional fertilization condition, 1) The application of corn stalks increased soil organic matter and available potassium contents and improved the integrated soil fertility of renovated tobacco field and the sensory quality of flue-cured tobacco. 2) The application of corn stalks combined with liming reduced the acidification effect caused by corn stalks, and promoted the formation of macro water-stable aggregate in soil and integrated soil fertility. However, corn stalks combined with liming were not beneficial to yield promotion and coordination of chemical composition of flue-cured tobacco. 3) The application of carbonized corn stalks combined with liming improved the integrated soil fertility of renovated tobacco field. Meanwhile, it also promoted the yields and chemical composition coordination of flue-cured tobacco. Therefore, long-term application of carbonized corn stalks combined with liming was recommended for renovated tobacco field.关键词
