玉树地区小黑麦不同播期生产性能研究

为了选择更适宜高寒牧区种植的一年生饲草,在玉树州称多县开展了小黑麦春季不同播期试验,对不同播期处理下株高,产草量等指标测定对比。结果表明:小黑麦株高在抽穗期受到播期的影响显著,但是在乳熟期影响不显著;不同播期对小黑麦产量的影响显著,播期太早和推迟都会直接影响小黑麦的产量,通过各种产量对比,小黑麦在本试验条件下最适宜的播期应控制在5月20～30日之间,可作为抗灾保畜的优质饲草进行利用。试验结果可为制定科学的高产栽培技术提供理论依据。

Study on the production performance of triticale in different sowing time in Yushu

In order to choose more suitable for planting annual forages in Alpine pastoral areas, the experiment of triticale sowing with different sowing date was implemented in Spring in Yushu prefecture. The plant height, yield and other indicators under different sowing date were determined. The results showed that plant height of triticale at heading stage was influenced greatly by sowing date, but in the milk- ripe stage the effect was not significant. The influence of different sowing date on triticale yield was significant, sowing date is too early or delay will directly affect the production of triticale. The optimum sowing date of triticale is between on May 20th and 30th. The test results provide theoretical basis for high yield cultivation of triticale.
