Straw-based pot body blanket seedling growth substrate and preparation method therefor

Abstract

A straw-based pot body blanket seedling growth substrate using straw fibres as a framework, utilising an enhancer, a retention aid and a wet strength agent as additives, and being prepared from composite decomposed livestock manure, perlite and vermiculite, the addition amount of the straw fibres being 60-70 v/v %, the addition amount of the decomposed livestock manure being 5-10 v/v %, the addition amount of the perlite being 5-10 v/v %, the addition amount of the vermiculite being 5-10 v/v %. The pot body blanket seedling growth substrate is suitable for cutting and easily implementing fully automated transplantation, is beneficial for root growth, shortens seeding growth periods, and increases seedling growth bed emergence rates. The pot body blanket seedling growth substrate may be applied to solanaceae seedling growth, and can also provide a block-shaped substrate for landscape flowers and plants in a three-dimensional arrangements.
