SCREENING OF SUITABLE FORAGE GRASSES FOR CULTIVATION IN THE ALPINE REGION OF QINGHAI
This study aimed to screen high-quality forage grasses suitable for cultivation in the alpine region of Qinghai by measuring and analyzing the production performance and nutritional value of four different grasses.The results showed that Festuca rubra subsp.arctica exhibited significantly higher plant height at both the flowering and full maturity stages compared to the other three species(P＜0.05).Its fresh weight and dry weight reached 192.00g/m2 and 74.82 g/m2,respectively,which were significantly higher than those of Festuca kryloviana and Deschampsia caespitosa(P＜0.05).In terms of nutritional composition,Festuca rubra subsp.arctica and Festuca kryloviana had significantly higher crude fat content,reaching 3.76％and 3.77％,respectively,indicating good nutritional value.Additionally,Festuca rubra subsp.arctica had the highest crude ash and calcium content,at 10.30％and 1.03％,which were significantly higher than those of the other species(P＜0.05).Based on a comprehensive analysis of all indicators,Festuca rubra subsp.arctica is recommended as a candidate forage grass for establishing artificial grasslands in the alpine pastoral regions of Qinghai due to its higher biomass and superior nutritional composition.This study provides a scientific basis for the selection and production of forage grasses in the alpine regions of Qinghai.
