【摘要】 为探索CO₂气肥随水施用技术,本文研究了作物根系对气态和水溶态¹⁴CO₂气肥的吸收、同化,随水吸收的¹⁴CO₂在水稻植株内的运行以及CO₂在水中的溶存、逸散。结果表明,作物经根系能吸收气态和水溶态¹⁴CO₂;水稻随水吸收的¹⁴CO₂在植株体内以气态运行;水中CO₂的溶存和pH值呈动态变化。更多还原

【Abstract】 This paper deals with the uptake and assimilation of CO₂ in the phase of gas or dissolved in water by plant roots, the transportation of [¹⁴C]CO₂ together with water in rice plants and the quantity of CO₂ dissolved in and escaped from water. The results showed that CO₂ gas or CO₂ gas-liquid could be absorbed by root system. [¹⁴C)CO₂ was transported in the form of gas in rice plant. The dissolution of CO₂ in water varied dynamically with water pH value.更多还原
