Abstract:

To explore the fertilization measures to improve black wax gourd quality, the effects of magnesium, iron, zinc, boron nutrients on the appearance and internal quality of wax gourd are studied. The results showed that magnesium application significantly improved the fruit shape and flesh firmness, and the sugar-acid ratio of wax gourd was increased by 23.4%. The contents of potassium, phosphorus, calcium and magnesium in the flesh increased remarkably, but the contents of Vc and free amino acids were not affected significantly. The trace elements slightly affected the shape and hardness of wax gourd, while averagely increased the sugar-acid ratio by 22.4%. Zinc, iron and boron significantly increased the Vc content of flesh, while copper and molybdenum reduced the free amino acid content in flesh.

Key words: magnesium, trace element, nutrition, wax gourd, quality
