研究了施用聚磷酸铵螯合微量元素肥对丝瓜生长的影响。结果表明,施用聚磷酸铵螯合微量元素肥的丝瓜产量显著高于对照以及单独添加ZnSO_4、MnSO_4的处理,而单独添加ZnSO_4、MnSO_4的肥料并没有起到促进丝瓜产量增加的作用;施用聚磷酸铵螯合微量元素肥的丝瓜中Zn平均含量以及Mn平均含量都是3个处理中最低的,但由于施用聚磷酸铵螯合微量元素肥丝瓜产量最高,因此所累积的Zn、Mn的总量显著高于对照以及单独添加ZnSO_4、MnSO_4的处理。
The effects of ammonium polyphosphate chelated trace element fertilizers on the growth of loofah were studied. The results showed that the application of ammonium polyphosphate chelated trace elemental loofah yield was significantly higher than the control and the addition of ZnSO_4, MnSO_4 treatment alone ZnSO_4, MnSO_4 fertilizer did not play an important role in promoting the yield of loofah; the application of polyphosphoric acid The average content of Zn and the average content of Mn in loofah with ammonium chelated trace element fertilizer were the lowest among the three treatments. However, the total amount of Zn and Mn accumulated due to the application of ammonium polyphosphate chelated the highest yield of trace elements, Significantly higher than the control and the addition of ZnSO_4, MnSO_4 treatment.
