摘要
为促进大渡河干旱河谷地区多年生巨菌草种植,探索最优平茬高度,以人工智能温室中巨菌草为研究对象,以未平茬巨菌草为对照,测定不同高度平茬处理后巨菌草的生长性状表现和复壮情况。结果表明,平茬处理可促进巨菌草更好地生长,平茬45 d后,平茬高度为20 cm的巨菌草叶片与茎秆生长最优,适宜用作饲料等;平茬高度为5 cm的巨菌草分蘖数最多,适宜用于水土保持和生态修复;平茬高度为15和10 cm的巨菌草长势一般,平茬高度为0 cm的巨菌草长势最差,不适用于平茬选择。
In order to promote the perennial planting of Cenchrus fungigraminus in the Arid Valley of Dadu River,and explore the optimal stubble height,the growth traits and rejuvenation of Cenchrus fungigraminus after treatment in artificial intelligence greenhouse were observed,the unleveled Cenchrus fungigraminus were used as control.The results showed that,stubble treatment could promote the better growth of Cenchrus fungigraminus.After 45 days of stubble,the leaves and stems of Cenchrus fungigraminus with the stubble height of 20 cm grew optimally,and were suitable for use as feed.The Cenchrus fungigraminus with the stubble height of 5 cm had the largest number of tillers,which were suitable for soil and water conservation and ecological restoration.Cenchrus fungigraminus with the flat stubble height of 15 cm and 10 cm grew normally,and the Cenchrus fungigraminus with the flat stubble height of 0 cm had the worst growth and were not suitable for stubble selection.
