摘　　要：采用取样测数法和合并测产法分别对中双4号、华杂6号甘篮型油菜产量进行了测定。结果表明,合并测产法具有取样测数法获得油菜产量要素及理论产量的优点,且便于操作、减轻了工作量,工作效率高,与实收产量的符合程度高,精确度高,为2．1％,其结果准确可靠。The methods of sampling estimation data and amalgamating yield estimation were introduced to estimate theory yield of zhongshuang 4 and Huaza 6 of Brassica napus L. in this paper .The results showed that the method of amalgamating yield estimation could obtain yield element component and theory yield of rapeseed the same as sampling estimation data, which is convenient to operate for lessening workload with high efficiency and has highly conforming yield with effective yield and high precision CEV2.1% with reliable outcome.
