不同播种量对贵草1号多花黑麦草生产性能的影响

The Effect of Different Sowing Quantity on Productive Performance of Guicao 1

对贵草1号不同播种量的再生速度、分蘖数、茎叶比、鲜草产量进行了测定,结果表明:贵草1号多花黑麦草的最佳播种量为3.8kg/667m2,其鲜草产量在3000kg/667m2以上,同时平均单株分蘖数32株,茎叶比最小,适口性好。

Guicao 1 was tested under different sowing quantity to investigate the effect on its regeneration speed, tiller ability, ratio of stem to leaf, and fresh grass yield. The results showed that the optimum sowing quantity is 3.8 kg/667m2. The fresh grass yield and average tiller number per plant is above 3 000 kg/667m2 and 32 plant, and its palatability is better because of the minimum ratio of stem to leaf under 3.8 kg/667m2 of sowing quantity.
