以“青苹果”竹芋为试材,采用盆栽种植与室内分析相结合的方法,分析了在固体酸调配营养液不同pH条件下对竹芋生长及地上部对养分吸收的影响。结果表明:在自来水配制和固体酸调配营养液pH的植株可以正常生长。与CK相比,各固体酸处理下叶面积不存在显著性差异;第106天时,除处理N1+SPA1和N2+SPA2外,CK与其它处理株高差异不显著,固体磷酸处理下植株叶绿素含量均呈增长趋势;Mo、Zn含量最高的N3+ASA3和N3+SPA3处理植株的2种元素含量相对处理CK显著降低了46.50%、23.13%,N3+SPA3处理的植株Mo含量在所有固体酸处理中最高,但积累量显著降低了45.09%。综上,该试验选取N3+SPA3为自来水配制配方肥料营养液的最佳养分浓度和固体磷酸调酸剂。
Using “green apple” and “arrowroot” as test materials, the effects of solid acid deployment nutrition solution on the growth of arrowroot and shoot nutrient uptake were analyzed by the combination of pot planting and laboratory analysis. The results showed that the plant with tap water and solid acid could grow normally. Compared with CK, there was no significant difference in the leaf area under each solid acid treatment. On the 106th day, except the treatment of N1 + SPA1 and N2 + SPA2, there was no significant difference between CK and other treatments. The chlorophyll content The content of two elements in the treatments of N3 + ASA3 and N3 + SPA3 with the highest contents of Mo and Zn were significantly decreased by 46.50% and 23.13%, respectively. The content of Mo in N3 + SPA3 treated plants was significantly decreased in all the treatments of solid acid treatment In the highest, but the accumulation of significant reduction of 45.09%. In summary, the experiment selected N3 + SPA3 tap water formulated fertilizer nutrient solution of the best nutrient concentration and solid phosphoric acid.
