饲用小黑麦品种在黑龙港地区的引进筛选

Introduction and selection of triticale varieties in Heilonggang region

对引进的12个饲用小黑麦(Triticum secale)品种在黑龙港地区进行了2年的比较试验研究,调查分析了产草量、籽粒产量、株高、茎叶比、鲜干比、抗倒性及结实率,结果表明:NTH1048、NTH1877地上生物量丰富但籽粒产量低,适合作为饲用型小黑麦种植;NTH2597、NTH2179干草产量、籽粒产量高适合于晒制干草和作为粮饲兼用型小黑麦品种种植,可充分利用冬闲田实现土地周年生产。

Two years of field experiment were carried out to study the 12 introduced forage triticale（Triticum secale） varieties in Heilonggang region,the forage yield,grain yield,natural height,the ratio of stem / leaf,the ratio of fresh / dry,lodging resistance and seed setting were investigated and analyzed.The results showed that NTH1048 and NTH1877 had more aboveground biomass but lower grain yield,therefore,they were suitable for cultivation as forage triticale;NTH2597 and NTH2179 had more dry yield and grain yield,so they were suitable for drying hay and cultivation as grain-forage triticale,and the goal of anniversary production could be achieved through use of winter fallow land.
