环境条件影响莎稗磷在土壤中的降解速度 :随着土壤温度的升高和含水量的增加 ,莎稗磷降解速度加快 ,在温度为 2 0、30和 4 0℃下 ,经过 10 d,莎稗磷的降解率分别为10 .4 %、2 6 .7%和 37.6 % ;在相对含水量为 30 %～ 110 %的土壤中 ,15d后莎稗磷降解 4 5.0 %～ 6 8.4 %。土壤中有机质能促进莎稗磷的降解 ,在有机质含量为 3.35%和 0 .55%的两种土壤中 ,莎稗磷的半衰期分别为 11d和 15d。莎稗磷在碱性土壤中比在酸性土壤中降解快 ,在偏酸性 (p H值为 6 .0 1)土壤中的半衰期为 2 2 d,在偏碱性 (p H值为 7.98)土壤中半衰期为 15d
Environmental conditions affect the degradation rate of Atripropium in soil: With the increase of soil temperature and water content, the degradation rate of P. xylostella was accelerated. Under the conditions of 20, 30 and 40 ℃, The degradation rates of P. aeruginosa were 10.4%, 26.7% and 37.6%, respectively. In the soils with relative water content of 30% -110%, the degradation rate of P. salina was 45.0% -6.44% after 15 days. Soil organic matter can promote the degradation of anilothium phosphorus. The half-lives of anilofos in the two soils with organic matter content of 3.35% and 0.55% were 11d and 15d, respectively. Anaphthofloxacin degraded faster in alkaline soils than in acid soils. The half-life in acidic (p H = 6.01) soils was 22 days, and in alkaline (p H = 7.98) soils Half-life of 15d
