云南红河州19个草品种适应性栽培试验

2021—2022年，在红河州中北部不同海拔、气候条件和生态环境，开展19个草品种发芽及生长情况对比试验。从发芽率、出苗率、高生长量、根系生长情况、草产量、植株内容物含量等方面进行对比分析。结果认为，从试验栽培的土壤类型看，红壤土上各草种的生长都优于沙壤土上；从海拔上看，高海拔区域更适宜于草本植物生长。

Adaptable Cultivation Experiment of 19 Grass Varieties in Honghe Prefecture of Yunnan Province

From 2021 to 2022, the comparative experiments were conducted on the germination and growth of 19 grass varieties at different altitudes, climatic conditions and ecological environments in the central and northern parts of Honghe Prefecture, and the germination rate, seedling emergence rate, height growth, root growth, grass yield, and plant content were compared and analyzed. The results showed that the growth of grass varieties on red soil was better than that on sandy soil; high-altitude areas were more suitable for the growth of herbaceous plants.
