目前,在农村科学试验中,计算小区产量。常用两种方法。即在测定小区的果穗鲜重后再抽样测定样品的果穗鲜重和样品的子粒风干重,一般按18个水(含水量18%)计算。应用下面两种公式;小区产量(18个水)=小区果穗鲜重×样品子粒风干重/样品果德鲜重×1-风干样品子粒含水量百分数/82×100小区产量(18个水)=小区果穗鲜重×样品子粒风干重/样品果德鲜重×(1+18/100-风干后子粒含水量百分数) 应用实例; 某玉米自交系小区面积20平方米,测产小区果穗鲜重为10公斤,抽10穗样品果穗鲜重为2.5公斤。风干后10穗样品脱粒称重2公斤,此时子粒含水量20%,求
Currently, in rural scientific experiments, the calculation of community output. Two commonly used methods. That is, after determining the fresh weight of a plot, the fresh weight of the sample and the dry weight of the grain of the sample are determined by sampling, and then 18 water (18% of water content) is generally calculated. Application of the following two formulas; plot yield (18 water) = fresh weight of plot × dry weight of sample grain / fresh weight of fruit sample × 1-% moisture content of dried sample pellet / 82 × 100 plot yield (18 water) = District ear fresh weight × sample grain air-dried weight / sample fresh fruit weight × × (1 + 18/100-moisture percentage of the water content of the particles) Application example; a maize inbred line area of 20 square meters, 10 kg, 10 spike samples ear fresh weight of 2.5 kg. 10 ears after air-dried samples threshing weighing 2 kg, at this time 20% water content of grain, seeking
