| 摘 要： | 设施土壤的pH、有机质与土壤环境质量及设施栽培作物生产水平密切相关。文章对云南不同区域、不同大棚种植年限、不同轮作制度的设施土壤pH与有机质的演变特征进行研究,结果表明:大棚种植年限长的地区,土壤pH、有机质变化明显;随着大棚种植年限的增长,土壤pH呈下降趋势,有机质含量则呈上升趋势;随着土壤层次的加深,大棚土壤pH逐渐升高,而有机质则逐渐降低;不同轮作方式,花-菜轮作比菜-菜轮作有利于增加有机肥对设施土壤pH的缓冲性。

| Abstract: | The soil pH and organic matter have closed relation to soil quality and greenhouse production. This paper analyses the greenhouse soil pH, organic matter in Yunnan province. The results showed that: in different areas, the soil pH and organic matter changed obviously. With the increasing of the greenhouse ages, the soil pH decreased and the content of organic matter increased. With the soil layer deepening, the soil pH increased, and the content of organic matter decreased gradually. Different crop rotation way, the buffer action of organic fertilizer to soil pH was the flowers-vegetable rotation better than vegetable- vegetable crop rotation |
