【摘要】 坡缕石为天然的纳米级生态功能材料,具有良好的吸附性和缓释性,作为农作物的营养剂和肥料的缓释剂广泛应用于生态农业之中。为进一步探明其生态功能,对马铃薯产量和品质效应的进行了田间试验,结果表明:坡缕石生态功能肥能有效地提高马铃薯产量,改善其品质。单施坡缕石可使马铃薯增产17.38%,和混合肥配施时可使马铃薯增产46.85%~59.95%;单施坡缕石可使马铃薯淀粉含量提高0.24%,和混合肥配施时可使马铃薯淀粉含量提高1.27%~3.81%。同时坡缕石具有对肥料的缓释效应。

【Abstract】 Palygorskite is natural and nanometer-sized ecological function material, due to its good adsorbability and slow-releasing effect; it can be used as neurotrophic agents of crop and slow-release formulation of fertilizer in ecological agriculture. To further prove its ecological function, the field experiment has been made to study the effect of fertilizer coated with ecological function material palygorskite on the yield and quality of potato, and the result showed that: ecological function material palygorskite fertilizer could effectively faise potato outputs and improve its quality. Single application of palygorskite could make the yield increased by 17.38%, and compound fertilizer with it could increase by 46.85%-59.95%; Single application of palygorskite could increase the starch content of potato by 0.24%, and compound fertilizer with it could increase by 46.85%-59.95%.So the results also showed that palygorskite has slow-releasing effect on fertilizer.
