钼肥对苋菜生长及品质、产量的影响

Effect of molybdenum on the growth,quality and yield of amaranth

试验采用0.67、1.00、2.00 mL/L的钼肥对苋菜(Amaranthus mangostanus L.)进行叶面喷施,研究钼肥对苋菜生长及品质的影响。结果表明,适宜浓度的钼肥可促进苋菜的生长,提高叶绿素含量,增加产量,改善品质,并降低叶片硝酸盐的累积。但在不同的生长发育期,其作用效应有所不同。以1.00 mL/L的钼肥处理效果较好。

0.67 ml/L, 1.00 mlL/L and 2.00 mL/L of molybdenum fertilizer was sprayed on the leaves of amaranth （Amaranthus mangostanus L.）. Growth and quality of amaranth was studied on molybdenum fertilizer. The results showed that suitable concentration of molybdenum fertilizer could promote the growth, improve the content of chlorophyll, increase amaranth production, improve the quality and decrease the accumulation of nitrates in the leaves of amaranth. However, the effect was different during different period. 1.00 ml/L of molybdenum fertilizer had the best effect.
