不同柳枝稷在盐碱地的适应性研究
Adaptability of Different Panicum virgatum in Saline-alkali Soil
摘要
Abstract
[Objective]To explore the adaptability of 12 varieties of Panicum virgatum to the saline-alkali environment in Yulin area,in order to provide theoretical guidance for the introduction of Panicum virgatum in saline-alkali land in Yulin area.[Method]A total of 12 plots were tested in the field of PB-1,PB-2,PB-3,PB-4,PB-5,PB-6,PB-7,PB-8,PB-9,PB-10,PB-11 and PB-12.The plant agronomic indexes and soil physicochemical properties of different Panicum virgatum were analyzed.[Result]PB-4 had the highest emergence rate,which was 46.53%.PB-1 grows best,reaching a height of 160 cm.The biomass of PB-10 was significantly higher than that of other varieties,which was 217.80 g/kg.The leaf area of PB-2 was relatively high in September and October,at 47.48 cm2 and 53.31 cm2,respectively.The soil mois-ture content may vary due to weather conditions,with PB-4 having the highest moisture content in August,reaching 16.59%;the moisture content of PB-3 was the highest in September,reaching 19.99%;the moisture content of PB-2 was the highest in October,reaching 17.58%.The soil bulk density of PB-4 decreased by 2.29%.The results indicated that the planting of PB-4 had a significantly better effect on the improvement of bulk density of saline-alkali land than other varieties.[Conclusion]Principal component analysis showed that PB-2 had the strongest adaptability with a score of 2.994,and was the most suitable among the 12 varieties for planting and promotion in the saline-alkali land of Yulin,northern Shaanxi.关键词
