[目的]解决生产上缺少饲草专用型谷子品种的问题。[方法]利用野生大谷莠子为原始材料,经多年多代的系统选育,育成饲用谷子品种冀草谷1号(S724)。[结果]冀草谷1号具有如下突出特性:1、粗蛋白含量高。谷草粗蛋白含量高,品质检测结果表明,粗蛋白含量达9.81%;2、鲜草、干草产量高。专家田间检测平均鲜草产量58 308.15kg/hm2,较对照饲草2号(35 763 kg/hm2)增产58.29%;干草产量15 922.65 kg/hm2较对照饲草2号(11 548.05 kg/hm2)增产37.88%;3、生物学特性,幼苗绿色,生育期122 d,株高198.22cm,穗长23.65 cm,茎叶比1.43,干鲜比37.86,种子产量3 383.4 kg/hm2;有分蘖,一般2~3个。[结论]该品种适宜在华北地区农闲田夏播或内蒙等地春播饲用,适合机械化收割。加大推广力度,可促进饲用谷子产业化开发。
[Objective] To solve the problem of lack of forage-specific millet varieties in production. [Method] The wild big valley herbivores were used as raw materials. After several generations of systematic breeding, the forage millet variety Jiashugu 1 was bred (S724). [Result] Ji grass valley 1 has the following outstanding features: 1, crude protein content is high. Asparagus crude protein content is high, the quality test results show that the crude protein content of 9.81%; 2, fresh grass, hay yield. Compared with the control forage 2 (35 763 kg / hm2), the average yield of fresh grass was 58 308.15 kg / hm2 in the expert field test, and the yield of hay was 15 922.65 kg / hm2 (11 548.05 kg / hm2) The yield was 37.88%; 3, biological characteristics, seedling green, 122 days growth stage, plant height 198.22cm, spike length 23.65 cm, stem and leaf ratio 1.43, fresh and dry ratio 37.86, seed yield 3 383.4 kg / hm2; 2 ~ 3. [Conclusion] This variety was suitable for spring sowing in summer in arable land in North China or in Inner Mongolia and other places, suitable for mechanized harvesting. Increase promotion efforts, can promote the industrialization of forage millet.
