摘要
试验采用随机区组设计，探索责单8号直播适宜种植密度，通过试验得出责单8号在密度为4424株／亩时亩产量最高达665．3公斤，3902株／亩的亩产量次之为648．9公斤，居第2位；2064株／亩的亩产量534．2公斤，居第5位。本试验中3902株／亩-4424株／亩为适宜的种植密度。
The experiment uses the randomized block design, explores the guidan 8 direct seeding being suitable planting density, obtains by experiment yield of guidan 8 are 9979.5kg/hectares when planting density are 66360/ hectares, ranking No 1; yield of 58530/hectare next are 9733.5kg/hectares, ranking No 2; yield of 30960/hectare are 8013kg/hectares , ranking No 5. In this experiment 58530/hectare - 66360/hectares for suitable planting density.
