在模拟条件下通过筛选选择2种亲水性材料聚乙烯醇和聚丙烯酸钠,并用2种材料制造了6种包膜肥料SRF-A1、SRF-A2、SRF-A3、SRF-B1、SRF-B2、SRF-B3。并用水浸泡法和土柱淋溶法检验其缓效性,最后得出SRF-A3和SRF-B3在同种材料中具有较好的缓效性。
Two types of coating fertilizers, SRF-A1, SRF-A2, SRF-A3, SRF-B1 and SRF-B2 were produced by screening two kinds of hydrophilic polyvinyl alcohol and sodium polyacrylate under the conditions of simulation. , SRF-B3. The water-immersion method and soil column leaching method were used to test the efficiency of SRF-A3 and SRF-B3. The results showed that SRF-A3 and SRF-B3 had good slow-acting properties in the same material.
