寒地鸭茅引种初探

黑龙江省尚无鸭茅栽培种，１９８５年以来，在三江平原寒冷地区进行了鸭茅引种试种。结果表明，从日本引入的５种品种中两个早熟和キタミドリ和ホクレン改良种已在八五三农场正常生长发育７年，但在佳木斯却未能正常越冬。初步认为，鸭茅引入寒冷的黑龙江省是有可能的，但还须对其限制因子做进一步研究。

A PRELIMINARY STUDY ON THE COLD AREA DACTYLIS GLOMERATA INTRODUCED

There were not any cultivated varieties of Dactylis glomerata. D. glomerata had been intreduced in theSanjiang Plain cold area since 1985. The result showed that among the five varieties introduced fromJapan, the two early maturing of them,had grown seven years on the 853Farm,however,they could not overwinter normally in Jiamusi.Therefore,it is possible for D. glomerata tobe introduced into the cold Heilongjiang Province,but its limiting factors have to be further studied also.
