【摘要】 针对我省优良抗性苜蓿(Medicago saliva L.)品种少、良种繁育技术落后、种子产量低、质量差等实际问题,通过对苜蓿无性扦插繁育、不同种植密度和切叶蜂(Megachile rotundata Fabricius)辅助授粉等关键技术的研究,确定最佳苜蓿良种繁育技术。结果表明:使用"108"生根宝液浸泡后扦插,成活率达78.8%;苜蓿种子田密度以30cm×70cm处理,种子产量最高(264.33kg/hm~2),比对照增产61.17%;利用苜蓿切叶蜂辅助授粉,最有效放蜂距离为30m,可使苜蓿种子增产27.23%～109.80%,效果显著。更多还原

【Abstract】 The optimum seed reproduction techniques of alfalfa is established according to researching on the effect of cuttage,planting with different density and pollinating by alfalfa leaf-cutting bee on seed yield with the problems of lacking high quality alfalfa,backward technology of alfalfa seed reproduction,low seed yield and low seed quality in HeiLongjiang province.The results showed that the survival rate may reach 78%with using"Sheng Gen-bao 108"fluid;the highestseed yield is 264.33 kg/hm~2 with density 30cm×70cm that increased 61.17%compared with the control;and the effective distance is 30m around the bee-cage of leaf-cutting,the seed yield can be increased between 27.23%and 109.80%.更多还原
