摘　　要：进行了移栽密度对稻板免耕油莱产量和效益的影响试验。结果表明，移栽密度对稻板免耕油菜产量、效益和菌核病发病程度有较大的影响，以90000～10．5000株／hm^2较为适宜，产量、效益较高，且有利于降低菌核病发生程度。The influences of transplanting densities on yield and efficiency of untilled rapeseed on rice plate were studied.The results showed that trans-planting densities had a great influence on yield, efficiency and sclerotinia incidence degree of untilled rapeseed on rice plate. Among which 90 000-105 000 hm^2 was more appropriate,with higher yield and efficiency ,and beneficial to reduce the degree of sclerotinia occurrence.
