为了研究禾本科饲草的生产性能,试验选用20种一年生禾本科饲草材料,在黑龙江省农业科学院草业研究所试验地进行田间种植,对其生产性能进行比较分析。结果表明:高丹草Late BMR、大力士以及苏丹草的PACF8421和健宝4个品种(品系)未能完成其生育期;青贮玉米的株高最高,与其他品种差异极显著(P<0.01),苏丹草中农26837的株高最低,只有191 cm;高丹草中Enorma和Bra-sero的分蘖能力最强,单株分蘖数分别为37.00,31.50个/株,极显著高于其他品种(P<0.01);高丹草Big Kahuma的鲜草产量高,抗倒伏能力和抗病性均较强。苏丹草中Enorma的分蘖能力最强,茎叶比最小,抗病性最强。综合比较,在20种饲草品种中高丹草Big Kahuma和苏丹草Enorma宜作为黑龙江地区青饲、青贮的禾本科饲草品种。
In order to study the production performance of gramineous forage grass, twenty year-old gramineous forage materials were selected to be field experimentally cultivated in the grassland research institute of Heilongjiang Academy of Agricultural Sciences, and their production performance was comparatively analyzed. The results showed that the four cultivars (lines) of Late BMR, Thalasso and Sudan grass were not able to complete its growth period. The height of silage corn was the highest, with significant difference from other varieties (P <0.01) , Sudangrass middle peanut 26837 had the lowest plant height of 191 cm, and Enorma and Bra-sero of sudangrass had the strongest tillering ability. The number of tillers per plant was 37.00 and 3.11 plants per plant, which was significantly higher than that of other cultivars (P <0.01). The fresh grass yield of Big Kahuma was higher than that of the control, and the lodging resistance and disease resistance were both good. Sudan grass Enorma strongest tillering ability, stem and leaf ratio is the smallest, the strongest disease resistance. Totally, Big Kahuma and Enorma in 20 forage varieties were used as grass forage and silage grasses in Heilongjiang Province.
