一试验目的和方法1959—1962年在山东农学院实习,曾先后用二十六个春小麦品种进行了夏季播种试验。关于春小麦夏播的生育状况,连续夏播对春小麦的影响,以及影响春小麦夏季栽培的几个主要因素等,已简要报导于山东农学院学报第七期。为了进一步比较春小麦秋播、春播和夏播的生育状况;了解因夏播所产生的变異是否能够稳定遗传,1962—1963年继续进行试验。试验包括两个主要部分。第一部分:将1961年秋播,1962年收获的合作二号、合作三号、合作五号、合作六号、贵州特早487等5个春小麦品种都分别进行秋播(10月21日)、春播(2月28日)和夏播(5月10日),比较不同时期播种的生育状况和单株生产力。
A test of purpose and method In 1959-1962 in Shandong Agricultural College practice, has conducted twenty-six varieties of spring wheat sowing test. The fertility status of summer sowing, continuous sowing of spring wheat, and several major factors that affect the cultivation of spring wheat in summer have been briefly reported in the seventh issue of Shandong Agricultural College. In order to further compare the fertility status of spring wheat sowing, spring sowing and summer sowing in spring wheat, and to know whether the variation caused by summer sowing could be inherited steadily, the experiment was continued from 1962 to 1963. The experiment consisted of two main parts. Part I: The five spring wheat varieties, which were sown in the autumn of 1961, the cooperation two, the cooperation three, the cooperation five, the cooperation six and the Guizhou early morning 487, which were harvested in the autumn of 1961, were respectively sowed in autumn (October 21) (February 28) and summer sowing (May 10) to compare the fertility status and plant productivity of sowing in different periods.
