| 摘 要： | 在石漠化土壤上开展少耕种植、秸秆覆盖、生物覆盖等保护性耕作栽培试验,研究各种措施对土壤环境质量及作物产量的影响.结果表明:与习惯耕作相比,少耕加秸秆覆盖是改善石漠化土壤质量较好的措施,能极大的改善石漠化土壤的理化性状:土壤有机质、全氮增加13.9％,19.6％；土壤容重降低21.5％,孔隙度增加5.4％；土壤微结构明显改善；土壤水分含量提高16.7％ ～35.6％,冬春干旱季节提高幅度更大达25.9％～60.4％；还能增加作物产量4.7％～5.3％.生物覆盖对土壤理化性状、土壤微结构、土壤水分等环境质量也有不同程度的改善及提高,但对作物产量有不利影响.而单纯少耕种植会导致土壤板结从而使作物减产.

| Abstract: | Applying reduced tillage,straw mulching treatment and organism mulching were used to conduct cultivating experiment and the effects of various measures on soil environmental quality and crop yield in rocky soil were studied.The result indicated that applying reduced tillage and straw mulching together could improve the physical and chemical properties of rocky soil efficiently. According to this experiment,reduced tillage and straw mulching treatment increased soil organic matter by 13.9 %,increased the tot... |
