摘要
通过盆栽试验及室内恒温培养试验探讨了 CA肥料中的包膜物质对小麦生长、土壤酶活性的影响及其高分子聚合物的分解性。结果表明 :膜物质对小麦生长与产量无不良影响 ;对土壤蔗糖酶活性没有明显的影响 ,对土壤过氧化氢酶有较明显的激活作用 ;经 4个月的恒温培养 ,膜物质中有机质分解率约为 3%。
Whether the coating material of CA fertilizers lead to pollution of soil and crops is a question awaiting a reply. Hence, we investigated the influence on wheat growth and soil enzyme activities and on degradation of the high polymer ingredients. The results obtained were as follows. No undesirable effects on wheat growth and yield were observed; No significant difference in soil sucrase activity was between plots of soil treated by the coating material and the control plots. Soil catalase activity was, however, remarkably enhanced. The degradation rate of coating material in soils was about 3% in 4 months under 25 ℃ indoor.
