摘要
在不同刈割频率、施肥量和混播比例下,对混播草地牛鞭草Hemarthria compressa和白三叶Triflium re-pen不同种群产量、地下生物量及分蘖数进行了研究。试验表明,刈割4次牧草蛋白质的收获量与刈割5次的差异不显著(P>0.05),而酸性洗涤纤维的收获量各处理间差异极显著(P<0.01),其中以刈割4次的最高,为1 135.1 g/m2。当刈割次数适当时,牛鞭草粗蛋白的收获量随着施肥量和禾草混播比例的增加而提高。
Three management factors including cutting frequency, the level of N fertilizer application and seeding rates of grass/legume were selected to study their effect on yield and the number of tillers. The results showed that the protein yield of mixture pasture on cutting 4 times and cutting 5 times was not significantly different （P〉0.05）. The ADF yield on every cutting time was significantly different （P〈0. 01）. The ADF yield on cutting 4 times was the highest. It was 1 135. 1 g/m^2. When the cutting time was moderate, the crude protein yield of mixture pasture was increased in the treatments of higher fertilizer and seeding rates than in other treatments.
