The study on new method of yield estimation of rapeseed

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.
