Abstract

Abstract:

According to the characteristics of growth and development of asparagus seedlings, the effects of different substrate layering ratios on asparagus seedlings were studied. In this study, 7 treatments were set up on six substrates, such as peat soil, coconut coir, and perlite, and the emergence rate and seedling rate, aboveground and root growth and development indicators, as well as physiological indicators of asparagus seedlings in each treatment were investigated. The results showed that a substrate layering ratio of 1∶3∶2 of pine bark, coconut coir, and peat soil was most beneficial for the growth and development of asparagus seedling roots, while a substrate layering ratio of 1∶3∶2 of perlite, peat soil, and pine bark was most beneficial for the growth and development of aboveground seedling. The emergence rate, and seedling rate with a substrate layering ratio of 1∶3∶2 of perlite, peat soil, and pine bark were the highest, and the effect on root growth and development was second only to the substrate layering ratio of 1∶3∶2 of pine bark, coconut coir, and peat soil. Compared with the conventional composite substrate, the above two substrate layering ratios with both water retention and breathability can significantly promote the development of asparagus seedling roots and realize the purpose of rooting and strengthening seedlings.

Key words: asparagus, seedling cultivation, substrate layering ratio, growth and development
