苜蓿品比试验研究

Comparative studies between alfalfa varieties

以新疆大叶苜蓿为对照品种进行品种比较试验,通过对苜蓿的出苗速度、生育期、产草量、抗寒性、抗病性及根茎直径与根茎入土深度等项指标调查研究结果表明,FunduleaI苜蓿出苗速度高于对照2 8%,第2,3年干草产量分别比对照增加16 4%与12 4%,成熟期比对照提前9～16d,且抗霜霉病。就抗寒性而言,FunduleaI苜蓿第2年越冬率略低于对照新疆大叶苜蓿,第3年与对照品种相同,2种苜蓿干叶率相比,FunduleaI苜蓿低于对照品种新疆大叶苜蓿。

Comparative experiments were carried out between two alfalfa varieties, Funduleal alfalfa and Xinjiang big leaf alfalfa (CK) Characteristics including germination rate, bearing period, forage yield, coldresistance, diseaseresistance, and diameter and depth of rootneck were investigated Results showed that compared with CK, the germination rate of Funduleal alfalfa was greater by 28%, hay yield in the second and third years was greater by 164% and 124% respectively, the maturity period was earlier 9～16d, and it resisted Peronospora Looking at coldresistance, the survival over wintering rate of Funduleal alfalfa in the second year was slightly poorer than CK, and was the same as CK in the third year Funduleal alfalfa had a lower dry leaf rate than CK
