添加燃煤脱硫废弃物和专用改良剂对碱化土壤和水稻生长的影响
Effects of flue gas desulfurization gypsum and krilium addition on alkali soil and rice growth
摘要
Abstract
Based on field experiment, changes in soil properties, including organic matter, total N, alkali-hydrolyzasable N, available P, available K, pH, exchangeable sodium percentage (ESP) and total salt, and rice characters including survival rate, individual height and yield were investigated to study the effects of flue gas desulfurization gypsum (FGDG) and krilium addition on alkali soil and their indirect effects on rice growth. The results showed that: the addition of FGDG and krilium increased greatly soil organic matter and nutrients content, and increased the survival rate,individual height and yield of rice by over 30.9％, 36.3％ and 64.8％, respectively, while they decreased soil ESP,pH and total salt content at a certain extent; among three Krilium types, Type Ⅲ had the most significant effect on soil ESP decrease, possibly resulting in the highest yield of rice; between three levels of Krilium Type I application, theplant with 11.25 t/hm2 of addition had the highest organic matter and available K content, which might be more favorable for rice growth, showing the highest yeild. Our findings indicated that the addition of FGDG and krilium improved soilproperties, possibly being conducive to rice growth. Additionaly, Krilium Type Ⅲ decreased soil ESP greatly, which re-sulted direactly in high yield of rice. However, it still needs further experiment to test the effect of Krilium Type Ⅲ and its application technique.关键词
