The principal component analysis was used to analyze the culture substrate formula of garden waste, which could provide scientific reference for comprehensive evaluation and selection of optimal formula. Nine groups of substrates for plant cultivation were prepared by using garden waste, soil and commercial nutritive soil as the main raw materials, in which the mass fraction of total decomposed and undecomposed garden waste reached up to 30%~40%, and non-renewable nature resources such as peat soil were not required. Most physical and chemical indexes of the substrate met the requirements of the national and industrial standards for cultivation substrates. The results of planting experiments showed that the germination rate of tall fescue seeds in the substrate was higher than 85%. The results of the comprehensive score evaluation of substrate formulas adopting "principal component analysis methodology" showed that the total porosity, nitrogen, phosphorus, potassium and total nutrients had the greatest influence on the physical and chemical properties of the substrates. The highest comprehensive evaluation score of nine substrate formulations was substrate 3, which was as follows: control soil/decomposed garden waste/undecomposed garden waste/commercial nutrient soil=5/3/1/1, and the mass fraction of total decomposed and undecomposed garden wastes reached 40% of the raw materials.
