利用~(14)C-PP333研究了它在不同土壤70％田间最大持水量及淹水情况下的降解动态。结果为两种处理的~(14)C-PP333均按指数衰减,半衰期分别为128～161d和144～224d。降解半衰期与土壤pH值呈负相关,在淹水情况下与土壤物理粘粒含量呈显著正相关。
The degradation kinetics of this plant under the maximum water holding capacity of 70% in different soils and flooding conditions was studied using ~ (14) C-PP333. The results for both treatments of ~ (14) C-PP333 are exponentially decay, half-life were 128 ~ 161d and 144 ~ 224d. The half-life of degradation was negatively correlated with soil pH value, and there was a significant positive correlation between soil half-life and soil clay content under flooding conditions.
