摘  要：
在海河平原区对11个饲用小黑麦品种进行了生产性能比较试验以及旱作条件下适应性,试验得出:冀饲-1成熟早,生育期短,抽穗期比对照中新830提前6d,干草产量高,比对照中新830提高26.7%,能与春播作物形成一年两作,适于在海河平原区推广利用;冀饲-2在海河平原地区鲜干草产量均较高,分别比对照中新830增产4 854.3kg/hm2和777.0kg/hm2,属于高产品种,茎叶比低,叶量丰富是海河平原区主要品种推广种植。旱作条件下种植,饲用小黑麦株高比正常管理条件下降低64.6%~83.4%,分蘖数和成穗数分别减少60.0%~74.7%和85.3%~98.1%,鲜干草产量分别降低69.3%和70.2%,利用价值不大,只有在一定的灌溉和施肥条件下种植才能产生较好经济效益。

摘  要：
The comparison experiment of productivity and adaptation under the rain-fed condition of 11 forage triticale cultivars were carried out in Haihe Plain area.The results indicated that the heading period of JS-1was 6days earlier than Zhongxin 830(CK)and the hay yield was increased by 26.7%,which could be used for double cropping with the spring-sown crop in one year and be suitable for extension.For JS-2,both fresh yield and hay yield were relatively high,which were 4854.3kg/ha and 777.0kg/ha higher than the CK respectively.As a high-yield cultivar with low stem-leaf ratio and abundant leaves,Js-2could be widely sown in Haihe plain.Under the rain-fed condition,the plant height reduced by 64.6% to 83.4%,the tiller number and heading rate decreased by 60% to 74.7% and 85.3% to 98.1% respectively,the fresh yield and hay yield decreased by69.3% and 70.2%respectively.This suggested that forage triticale should be grown under irrigation and fertilization conditions so that the economic benefits could be gained.
