| 文章研究有机施肥对粤东乌龙茶茶园土壤自然含水量和土壤容重等物理性质、有机质、全氮、碱解氮等土壤养分的影响.结果表明：铺草、施绿肥、施有机肥均能提高土壤自然含水量和有机质质量比，而施有机肥对提高土壤有机质质量比的效果最好；施绿肥和铺草对于提高土壤全氮和碱解氮质量比的效果不明显，而施有机肥可以明显提高土壤全氮和碱解氮质量比。粤东各地茶园可以因地制宜，采取施有机肥结合铺草措施，改善本地茶园土壤，保证土壤肥力供应和含水量。 |

| Abstract: |
| The effects of organic fertilization on soils physical properties, like soil?moisture content and soil?bulk?density, organic matter, total nitrogen, alkali-hydrolysable nitrogen and other soil nutrients were studied in eastern Guangdong Oolong Tea garden. The results showed that straw mulching, green manure and organic fertilizer could improve the soil moisture content and organic matter mass ratio, while the organic manures had the best effect on improving soil organic matter mass ratio. The effects of applying green manure and straw mulching on soil total N and available N were not obvious, while organic manures could obviously improve the ratio of total nitrogen and alkali-hydrolyzable nitrogen. The tea garden in eastern Guangdong could be adapted to local conditions, and take the measures of organic fertilizer combined with straw mulching to improve the local tea garden soil and ensure the supply of soil fertility and moisture content. |
