研究三种优良牧草白三叶、草地早熟禾、多年生黑麦草在不同播种方法情况下的生物学性状及经济性状,结果表明:混播牧草比单播牧草在杂草防除、叶面积指数提高及生物学产量的增加有显著的优势,试验结果可为当地的饲料生产及草地改良提供可行的依据。
The biological characteristics and economic traits of white clover, meadow bluegrass and perennial ryegrass under three kinds of sowing methods were studied. The results showed that the mixed-forage grass had better weed control, leaf area index and biomass There is a significant advantage in the increase of yield, and the result of the experiment can provide a feasible basis for the local feed production and grassland improvement.
