摘要
[目的]研究氮磷钾肥对剑麻生产的影响.[方法]在麻园开展“3414”试验,分析肥料使用后,土壤供肥能力、植株对养分吸收量和肥料利用率等.[结果]在一定的施用量范围内,随着N施用量的增加,产量也随之增加,而达到一定的极限时,产量反而降低;P、K的施用量对产量产生效果的趋势是相同的,其规律不明显,可能是土壤P、K含量已充足.试验检测发现,叶片锾含量缺乏,施锾肥可显著促进产量的提高.[结论]该研究可为精准平衡施肥提供参考,从而提高肥料的效益.
Abstract
[Objective] The objective is to study the effect of NPK fertilizer on sisal producing.[Method] The"3414" fertilizer test was carried out to analyze soil supplying nutrient capability,nutrient uptake of plant,fertilizer use efficiency and so on after applying fertilizer in sisal garden.[Result] Among application amount rang,yield increased with N amount increasing,yield decreased when application amount was too high.Effect of P,K application amount on yield was same,but the law was not obvious,it was possible that P,K content of soil was sufficient.Magnesium deficiency was discovered in leaf by detecting.Applying magnesium fertilizer could improve sisal's yield.[Conclusion] The research can offer reference for balanced fertilization.
