为了解胜利油菜生育特性、丰产性能及其与不同播种期的关系,进一步明确其播种适期,夏播的增产潜力及冬播、春播的丰产可能性,我们于1960—61年度对其进行了夏、秋、冬、春四季播种试验。 本试验共设12个播种期,小区面积0.3亩,顺序排列。处理情况详表一。 试验结果分析一、周年播种对生长发育的影响1.周年播种对生育时期的影响 试验结果,早播者各发育时期相应提早,迟播者显著延迟,惟第一组各期之间差異不大。春播(2/11)者到6月上旬才成熟,收获时还有20％植株未现蕾。(表二) 生育历程随播期延迟而依次减短或加
To understand the reproductive characteristics of Shengli rape, its high yield performance and its relationship with different sowing dates, we further clarified the potential of sowing date, yield potential of summer sowing, and high yield of winter sowing and spring sowing. We conducted this in 1960-61 Summer, autumn, winter and spring seeding trials. The test consists of 12 sowing period, the plot area of 0.3 acres, in order. A detailed list of treatment. The results of an analysis of the impact of annual planting on the growth and development of 1 anniversary of the impact of sowing on the reproductive period of the test results, early stage corresponding to the early development of each period of development was delayed significantly delayed, but the first group was not significantly different between the various stages . Spring sowing (2/11) does not mature until early June, with 20% of the plants harvested at harvest. (Table 2) Fertility process with the sowing delay in turn shorten or add
