Effect of soil conditioner on the growth of Lolium multiflorum

doi:10.11686/cyxb2014503

Abstract

Abstract: To explore the effect of soil conditioners which are applied to semiarid regions of the Loess Plateau, this study compared pots planted with Lolium multiflorum seed with and without the soil conditioners. Three self-made soil conditioners (A, B, C) and a standard soil conditioner (D) were compared. The results showed that soil conditioner application can significantly improve soil perviousness, but there was no difference in seedling emergence rates between untreated and soil conditioner treated pots. Soil conditioner C produced significantly better height growth in L. multiflorum plants, 16.6% and 33.7% higher than that of the standard soil conditioner and the untreated soil respectively. Tiller numbers in pots treated with soil conditioner C were 18.5% and 33.8% higher than that of standard soil conditioner and the untreated soil respectively while the biomass was 40% and 185% higher, respectively. The appearance utilization rate of phosphorus was 10.28% treated with soil conditioner C. Therefore, self-made environment-friendly soil conditioner C was the best soil conditioner among them. The study will provide a theoretical guide for soil conditioner application and vegetation restoration in semiarid regions of the Loess Plateau.
