摘要: 采用根际袋法研究腐熟有机物料对滨海盐土水稻淹水层及土壤的盐分和植株元素吸收的影响。结果表明,在不排水条件下,施用有机物料使淹水层盐分上升,土壤盐分也高于对照,但其根际富集程度降低;植株K吸收增强,Na则明显下降,Ca、Mg含量略增,但变化没有1价元素明显。

Abstract: The effect of composted organic material on the salinity of coastal saline paddy soil and its submerged layer and the uptake of elements by rice plant is studied with rhizobox method.The results show that under no drainage condition.the application of organic material increases the salinity of soil and its submerged layer, but decreases the accumulation of salts in paddy rice rhizosphere.It can enhance the uptake of K, Ca and Mg, and decrease that of Na by rice plant.
