小黑麦在黄冈市作为青贮饲料的适应性试验

Study on Introduction Experimental of Planting Triticale in Huanggang City

为了解小黑麦在湖北省黄冈市作为青贮饲料的应用前景,对引进的3个小黑麦材料开展了播期和收获期适应性试验。结果表明,不同材料间的农艺性状间存在差异。就同一材料不同播期差异而言,农艺性状间差异不太明显。但播期对小黑麦单位面积的鲜重影响很大,这可能是由于播期越迟、分蘖越少、收获株数越少导致的。其中小黑麦材料"3241"在11月5日播种、第二年5月6日收获的鲜草产量最高,达到3.24 t/667 m^2。小黑麦和小麦的性状间比较表明,引进的3个小黑麦材料株高和单茎鲜重均远大于小麦。

In order to understand the application prospect of triticale in Huanggang city of Hubei province as silage,the adaptability test of sowing stage and harvest time was carried out for3introduced materials.The results showed that there were differences in agronomic characters between different cultivars.In terms of different seeding periods of the same material,the difference of agronomic characters is not obvious.However,the effect of sowing time on the fresh weight of triticale is huge,which may be due to the shorter tillering time and the less number of harvest plants for the late planting time.Among them,the maximum yield was3.24t/667m2,of materials3241,which was seeded on5th November,harvested on6th May.The comparison between the characteristics of triticale and wheat showed that fresh weight of single stem of the three triticale materials were much higher than that of wheat.
