| 摘 要： | 为提高水稻区域试验准确度和精确度及减轻后期测产工作量,2005年早、晚两造分别对10个和9个参试水稻组合进行折干率计产的比较试验,以小区湿谷重的5%、10%和15%3种比例取样,晒干后对折干率计算的小区干重与实际干重进行比较。结果表明,按3个取样比例的折干率计算的小区干重与实际干重差异不显著。提出在实际应用中采用10%的比例取样,2次重复,以2次折干率的平均值计算小区干重。

| Abstract: | In order to improve the accuracy of rice regional trial and alleviate workload of yield measurement in late harvesting stage of rice,a comparative dry weight analysis between theoretical weight(measured by drying rate) and the actual weight was performed in 2005.Ten early and nine late tested rice combinations were planted and the 5,10 and 15% proportions of wet grain samples were collected.The results showed that there was no significant difference between dry weight in plots calculated according to the dr... |
