在近几年的棉花试验中,年度间复演性较差,通过分析我们发现,其主要原因是由于棉种的贮存年限不同而造成的。为了解不同贮存年限的棉种对产量等有关性状的影响,我们于1987年进行了研究试验。一、试验材料与田间设计供试品种为冀棉4号和冀棉8号,各以贮存4、3、2、1年的种子参与试验。田间设计:6行区,行长10米,大小行种植,平均行距66厘米,随机排列,重复三次,以贮存1年(即1986年收获)的种子为对照种,播
In recent years, cotton experiments, the annual recurrence of the poor, through our analysis, we found that the main reason is due to the different shelf life of cotton species caused. In order to understand the effect of cotton varieties with different shelf life on yield and other related traits, we conducted a research experiment in 1987. First, the experimental materials and field design for the test varieties Jimin 4 and Ji Mian 8, each to store 4, 3, 2, 1 year seed to participate in the experiment. Field design: 6-line area, the governor of 10 meters, the size of rows of planting, the average spacing of 66 cm, randomly arranged, repeated three times to store 1 year (1986 harvest) seeds as control, sowing
