为了提高大豆区域试验的准确性,尽量减少人为因素造成的试验误差,从而极大限度地发挥大豆参试材料的增产作用,为我省选育出更加优良的大豆新品种。我们在实践中采取了以下几项行之有效的措施,使试验的准确性达到了较高的标准。 1 整地精细,杜绝堑沟区和岗垄区试验地中的堑沟,会给试验造成很大的差异。由于堑沟区的冷凉和岗垄区的温热,两种试验区的产量差异从我们多年的经验摸索中得出最高可达25%,排布到这两种小区上的参试材料的产
In order to improve the accuracy of the test in the soybean area and try to reduce the experimental error caused by human factors, the yield increase effect of the soybean test material is exerted to a great extent, and a better new soybean variety is bred in our province. In practice, we have taken the following several effective measures to make the accuracy of the test to a higher standard. A fine preparation of land, put an end to cut trenches and gullies experimental ditch in the trench, will give the test a great difference. Due to the cooling of the ditch region and the warming of the gangue area, the difference in yield between the two experimental areas can reach up to 25% from our years of experience and exploration, and the distribution of the tested materials to these two plots Production
