苜蓿与不同禾草混播的研究

本文介绍了在乌鲁木齐灌溉条件下,苜蓿(Medicago varia Martyn)+无芒雀麦(Bromus inermis leyss);苜蓿+苇状羊茅(Festuca arundinacea Schreb.);苜蓿+猫尾草(Phleum pralenss L.);苜蓿单播;苇状羊茅及无芒雀麦单播等处理的混播试验。研究结果表明苜蓿与一种禾草混播比禾草单播显著增产。单播一种禾草产量很低不宜采用;建立打草人工草场,以苜蓿+无芒雀麦组合为好,建立打草和放牧兼用草场,以苜蓿+苇状羊茅为好。

Study on Mixture of Alfalfa with Different Grass Species

Different mixture treatments, which included alfalfa (Medicago varia Martyn) with smooth bromegrass (Bromus innermis Leyss) ; with tall fescue (Festuca arundinacea Schrcb.) and with timothv (Phlcum pratense L.), and treatments of alfalfa, smooth bromcgrass and tall fescue seeded alone were tested under irrigation condition in Urumqi. Results showed that, mixtures of alfalfa with any tested grass specie could yield higher than grass seeded alone, for their low yielding capacity, it is better not to seed grass alone. Mixture of alfalfa with smooth bromcgrass is suitable to be used for cutting grassland establishment, mixture combination of alfalfa with tall fescue is suitable to establish grassland used both for cutting and grazing.
