鸭茅、“81-01”纤毛鹅观草与红三叶混播对比试验小结(1988～1989年)

A BRIEF SUMMARY OF THE COMPARATIVE EXPERIMENT OF THE MIXED SOWING OF ORCHARDGRASS AND 81-01 ROEGNERIA CILIARIS WITH RED CLOVER(1988～1989)

试验表明,鸭茅产草量比纤毛鹅观草高8.2%.鸭茅前期生长缓慢,利于红三叶生长,二者的协调性比纤毛鹅观草与红三叶混播好.在刈割3次(终刈时间1989年6月1日)的情况下,鸭茅越夏率90%以上,纤毛鹅观草80%以上,而红三叶越夏率很低.

The experiment showed that the yield of Orchardgrass was 8.2% higher thanthat of Roegneria ciliaris.The slow growth of Orchardgrass at the early stage was be-neficial to red clover's growth.The concordance of Orchardgrass with red cloverwas better than that of Roegneria ciliaris with red clover.After cutting threetimes(the last cutting on 6 1st 1989),the oversummering percentage of Orc-hardgrass and Roegneria ciliaris were above 90% and 80% respectively but thatof red clover was very low.
