尿液制备磷酸铵镁对茼蒿生长及品质的影响

Effects of Preparing Magnesium Ammonium Phosphate From Urine on the Growth and Quality of Chrysanthemum annuum

以茼蒿为试材,采用盆栽的方法,通过设置普通复合肥(T1)、尿液制备磷酸铵镁包膜缓释肥(T2)、尿液制备的磷酸铵镁肥料(T3)、空白对照(T4)等4组平行试验,研究了不同的试验条件对茼蒿生长及品质的影响,以期使尿液得到资源化利用的同时未来有可能替代商业肥料对农作物种植提供参考依据。结果表明:3种肥料的肥效均显著高于对照,其中磷酸铵镁肥料对茼蒿处理的成活率高,收割期磷酸铵镁作用的茼蒿株高和茎粗是对照的1.43、1.54倍;鲜质量总生物量、干质量总生物量分别是对照的5.80、4.40倍;产量比对照提高了4.63倍;根系长度是对照的1.44倍;N、P的积累量均较对照高出2倍;可溶性糖含量和维生素C含量分别比对照高出1.46倍和3.00倍;包膜缓释肥和磷酸铵镁植株中的硝酸盐含量符合标准并低于复合肥,其中尿液制备的磷酸铵镁肥料的硝酸盐含量比对照高出1.17倍。综上,尿液制备的磷酸铵镁肥料不仅解决了尿液处理难的问题,也可以作用于农业种植,具有良好的发展前景。

Taking Chrysanthemum annuum as the experimental material,the method of potted plants was carried out.Four parallel experiments were conducted by setting up ordinary compound fertilizer(T1),urine prepared ammonium magnesium phosphate coated slow-release fertilizer(T2),urine prepared ammonium magnesium phosphate fertilizer(T3),and blank control(T4).The effects of different experimental conditions on the growth and quality of Chrysanthemum annuum were studied,in order to provide reference for crop cultivation while utilizing urine as a resource and potentially replacing commercial fertilizers in the future.The results showed that the fertilizer efficiency of the three fertilizers was significantly higher than that of the control.Among them,ammonium magnesium phosphate fertilizer had a higher survival rate for the treatment of Chrysanthemum annuum.During the harvesting period,the plant height and stem diameter of Chrysanthemum annuum treated with ammonium magnesium phosphate were 1.43 and 1.54 times higher than those of the control.The total biomass of fresh weight and total biomass of dry weight were 5.80 times and 4.40 times higher than those of the control,respectively.The yield increased by 4.63 times compared to those of the control.The root length was 1.44 times that of the control group.The accumulation of N and P was 2.00 times higher than that of the control group.The soluble sugar content and vitamin C were 1.46 times and 3.00 times higher than those of the control,respectively.The nitrate content in the coated slow-release fertilizer and magnesium ammonium phosphate plants met the standard and was lower than that in the compound fertilizer.The nitrate content in the magnesium ammonium phosphate fertilizer prepared from urine was 1.17 times higher than that in the control.In summary,the ammonium magnesium phosphate fertilizer prepared from urine not only solved the problem of difficult urine treatment,but also had good development prospects for agricultural cultivation.
