野生硬雀麦栽培驯化研究

Study on the cultivation and acclimation of the wild forage——Bromus rigidus

通过硬雀麦Bromus rigidus与3种一年生黑麦草Lolium multiflorum和莜麦Avena nuda的品种比较试验,结果表明:硬雀麦产草量达76 095.0 kg/hm2,仅次于阿伯德多花黑麦草(77 589.0 kg/hm2),略高于邦德一年生黑麦草(74 212.5 kg/hm2),三者之间差异不显著(P>0.05);高于赣选1号多花黑麦草(67 033.5 kg/hm2)和莜麦(66 697.5 kg/hm2),差异极显著(P<0.01)。硬雀麦的播种量以73.3125 kg/hm2,行距15 cm为最佳,平均产量可达98 227.5 kg/hm2。硬雀麦可作为过渡带冬闲田种植的优良牧草。

The test was carried on the variety comparison of Bromus rigidus, Avena nuda and 3 annual ryegrasses. Results were shown that the yields of B. rigidus, Lolium multiflorum cv. Aubade and L. multiflorum cv. Abundant were 76 095.0, 77 589. 0 and 74 212.5 kg/hm^2 respectively. There weren＇t significantly difference among them. But the yields of B. rigidus and L. multiflorum cv. Ganxuan No. 1 differed significantly at P〈0.01 level. The best cultivation pattern of B. rigidus was sowing density 73. 312 5 kg/hm^2 and row spacing 15 cm. The average yield of B. rigidus could reach to 98 227. 5 kg/hm^2 and was about 1.29 times of those of other forages. B. rigidus was the better forage for the winter fallow field in the transitional zone.
