1 区试中误差的来源,主要有以下几种 1.1 试验地不合格,这是误差的主要来源。试验地不合格有以下几个方面: ①试验地不够平坦,肥力不够均匀,这样势必造成处理小区的产量随地势和肥力的变化而起伏不定,失去了试验结果的准确性,以致难以判断每个参试品种的优劣。②试验地面积不足或不固定,不能搞合理的轮作,不能搞匀地。③试验地离村屯较近,不利于保护科研成果,易受人畜危害,使试验前功尽弃。
1, the source of the error in the district test, there are several following 1.1 failed test, which is the main source of error. Test unqualified in the following areas: ① test is not flat enough, fertility is not enough uniform, which will inevitably result in the production of plots of plots with the topography and fertility changes undulating, losing the accuracy of the test results, it is difficult to determine each The pros and cons of the varieties tested. ② lack of test area or not fixed, can not engage in reasonable rotation, can not engage in uniform. ③ The test site is closer to the village, which is not conducive to the protection of scientific research and is susceptible to human and livestock hazards.
