复合保水剂的水肥调控模拟及其肥效研究
摘要
利用土柱模拟试验和盆栽试验研究了复合保水剂对水肥淋失和玉米农艺性状的影响
土柱试验结果表明
加入复合保水剂后能够较对照减少淋出液体积
显著降低氮磷钾的累计淋溶率;盆栽试验结果表明
施用复合保水剂能够显著提高玉米的生物学产量和肥料的利用率.
Abstract
This paper studied the effects of complex super absorbent polymers on nitrogen and water leaching and agriculture character of the maize through soil column test and pot experiment.The soil column test showed that the volume of eluviations was reduced;the accumulative leaching losses of soil nitrogen
phosphorus and kalium were depressed in treatment with complex super absorbent polymers.The pot experiment showed that the biomass of maize and fertilizer use efficiency was increased visibly in treatment with Complex super absorbent polymers.
