Abstract:

In order to reduce watermelon factory seedling production cost, the formulation of the nursery substrates to solve the problems, watermelon ‘Heifeicui’ as material, selected seven different nursery substrates to compose the agronomic characters and physiological indexes of different treatments, investigated the effect of different nursery substrate on seedling quality of watermelon. The result turned out that: different nursery substrates had important effect on the biological yield, the root activity, the photosynthetic pigments and protein of ‘Heifeicui’. The proportion of perlite, peat soil and culture medium waste of mushroom 1:1:2 was beneficial to improving seedling quality of watermelon.
