不同切根打孔参数条件下伊犁山地草甸土壤物理性质与产草量研究
Soil Physical Properties and Grass Yield under Different Root Cutting and Punching Parameters in Yili Mountain Meadow
摘要
Abstract
Aiming to investigate the effects of root cutting and punching combinations on soil improvement and grass yield in mountain meadow soils,a targeted experiment was conducted in the Yili River Valley from May 2023 to September 2024.The experimental factors included root cutting depths(5 cm,10 cm,15 cm),punching(20 cm,40 cm,60 cm),and a control(CK).The experiment aimed to analyze their influence on the soil's physical properties and grass yield,providing a comprehensive understanding of how these treatments affect the ecosystem.The results showed that root cutting reduced soil bulk density by 14.58％to 20.83％,reduced soil specific gravity by 3.54％to 9.73％,increased soil porosity by 2.76％to 5.47％,and significantly boosted fresh grass yield by 26.54％to 36.01％,and dry grass yield by 18.46％to 26.80％,while also reducing soil compaction.Similarly,punching reduced soil bulk density by 16.67％to 17.71％,reduced soil specific gravity by 2.65％to 7.96％,increased soil porosity by 1.52％to 5.56％,and improved fresh grass yield by 20.68％to 35.08％,and dry grass yield by 9.31％to 29.49％,while also enhancing soil compaction.The combination of root cutting and punching effectively improved soil physical properties and increased grass yield,leading to a better mountain meadow environment.Among the treatments,D60Q5 demonstrated the most significant effects on both soil improvement and yield increase,providing both ecological and economic benefits.In conclusion,the optimal root cutting depth was 5～10 cm,and the optimal punching spacing was 40～60 cm.The combination of punching at 60 cm and root cutting at 5 cm provided a sustainable and efficient approach to improve soil physical properties and increase grass productivity,which can be considered as the optimal solution for improving the mountain meadows in the Yili River Valley.关键词
