瑞拉菌素对10种作物幼苗生长的影响

Effects of Zuelacmycin on Seedling Growth of Ten Crops

用3个浓度梯度的瑞拉菌素稀释液对辣椒、芥菜、萝卜、黄瓜、玉米、韭菜、水稻、小麦、高粱、番茄10种作物进行室内砂培试验,测定供试作物的出苗率、根长、苗高、鲜质量4项指标。结果表明,浸种处理时,3种浓度的瑞拉菌素稀释液对萝卜、玉米、辣椒、芥菜4种作物是安全的,韭菜和水稻的最低安全浓度是100倍的稀释液,黄瓜、小麦、高粱最低安全浓度是400倍的稀释液,但3种浓度的稀释液对番茄生长均有显著抑制作用。

The experiment was to observe effects of Zuelacmycin on seedling growth of different crops and to give a clue for its application.Different concentrations of Zuelaemycin were applied to the sand culture test in ten different kinds of crops,Brassicana piformis L.H.Bari,Capsicum annum L,Raphanus sativus L,Cucumis sativus L,Zea mays L,Triglochin maritimum L,Oryza sativa L,Triticum aestivum L,Sorghum cernuum（Ard.）Host,and Lycopersicon esculentum Mill.Indicators of determination included the emergence rate,length of root,height of seedlings,and fresh weight.The results showed that three kinds of concentrations of Zuelacmycin were safe for Raphanus sativus L,Zea mays L,Brassicana piformis L.H.Bari,Capsicum annum L The minimum safe concentrations were 100 times diluted of Zuelacmycin for Triglochin maritimum L,Oryza sativa L,and 400 times for Cucumis sativus L,Triticum aestivum L,Sorghum cernuum（Ard.）Host.However,the three kinds of concentration of diluent significantly inhibited the growth of Lycopersicon esculentum Mill.
