| 摘 要： | 选用硫膜和树脂膜两种肥料膜壳,每种设置3个浓度梯度,研究了控释肥膜壳对土壤理化性质的影响。结果表明,施入膜壳后能增大土壤孔隙度,改善通气状况;施用硫膜和树脂膜引起土壤pH值下降和电导率提高,施用树脂膜壳的各个处理铵态氮和硝态氮含量均有不同程度的降低,降低幅度分别为13.83%～39.0%和3.48%～20.37%;施用硫膜提高了土壤水溶性SO24-和Cl-含量。

| Abstract: | Sulfur film and resin film were used, and each membrane shell was Set by three concentration gradients. We studied the effects of the membrane shell on soil physical and chemical properties. The results showed that application of membrane increased soil pores and improved the ventilation conditions. Application of sulfur film and resin film decreased soil pH and increased soil Ec. Application of resin membrane shells decreased ammonium and nitrate content by a certain extent, and the rate was 13.83% -39.0% and 3.48% - 20.37% respectively. Application of sulfur membrane also increased soil water-soluble SO4^2- and Cl^- content. |
