试验田是开展农业科学实验活动的重要阵地,试验田选择和设计的好坏,关系到试验结果的准确性.试验田应选择在土质、肥力和地形有一定代表性的地方,要求地势平坦,土壤肥力均匀,耕作、通风和光照条件一致,避免在树旁、屋旁以及易遭家禽、家畜损害的地方作试验田.根据试验性质的不同,试验田的设计可分大田试验和小区试验两种.凡是比较有把握的增产措施,为了进一步肯定它的增产效果和推广价值,并向群众作示范的,一般以采用大田试验为好.因为大田试验的面积大,代表性大,操作较为方便,计算产量时的正确性也较
The experimental field is an important front for carrying out agricultural science experiments, and the selection and design of the experimental field is good and bad, which is related to the accuracy of the experimental results. The experimental field should select a place where the soil quality, fertility and topography are representative, requiring flat topography and uniform soil fertility , Tillage, ventilation and light conditions, to avoid the trees next to the house and vulnerable to poultry and livestock damage areas for experimental fields.According to the nature of the test, the experimental field design can be divided into field test and plot test two. Grasp the stimulation measures, in order to further affirmed its stimulation effect and promotion of value, and to demonstrate to the masses, the general field test is better to use because the field test large area, large representative, more convenient operation, the calculation of production The correctness is also more
